Nevada Road Signs Practice Test cheat sheet

Sign shapes carry meaning by themselves: octagon = stop, inverted triangle = yield, horizontal rectangle = guide or warning information, vertical rectangle = regulatory, diamond = warning, pennant = no-passing zone, round = railroad advance warning, crossbuck = railroad crossing.

Sign colors: red = stop, yield, or prohibition; yellow = general warning; fluorescent yellow-green = pedestrian, bicycle, and school warning; orange = construction and maintenance; blue = motorist services; brown = recreation and cultural interest; green = guide and permitted movements; white = regulatory; purple = electronic toll collection.

A flashing red signal is treated exactly as a stop sign: full stop, yield, then proceed when clear. A flashing yellow signal means slow down and proceed with caution; it never requires a stop by itself.

A steady yellow light means the signal is about to turn red; stop if you can do so safely, otherwise clear the intersection. Entering on red after the yellow has ended is a red-light violation.

Solid yellow center lines separate traffic moving in opposite directions; you may cross them only to turn left or into a driveway. Double solid yellow means no passing in either direction.

Broken yellow center line on your side permits passing when safe; broken white lines separate same-direction lanes and may be crossed to change lanes; solid white lines mark the right edge or a lane you should not cross.

A red X over a lane means that lane is closed or its use is prohibited; a green arrow means the lane is open in that direction. A white diamond marks a high-occupancy vehicle (HOV) lane.

At a crossbuck railroad crossing, yield to trains; a stop is required only if a signal, gate, or flagger indicates one. Never stop on the tracks, and remember a train at 55 mph can take a mile or more to stop.

Pavement markings reinforce signs and signals: stop bars mark where to halt at a signal or stop sign, crosswalk lines mark pedestrian paths, and chevron or diagonal markings indicate areas you must not drive over.

Nevada requires use of a safety belt by the driver and all passengers, and children under 6 years old and under 60 pounds must be secured in an appropriate child restraint system in the rear seat.

Turn signals must be given before changing lanes or turning, and the signal must be visible to other drivers for a reasonable distance before the maneuver; cancel it after completing the move.

Drive on the right half of the roadway except when passing, when the road is divided into lanes for one direction, or when a one-way street allows otherwise.

When a school bus stops with red lights flashing on a two-lane road, traffic in both directions must stop until the lights stop flashing; on a divided highway, only traffic behind the bus must stop.

Passing is prohibited on hills and curves where the view is obstructed, at railroad crossings, at intersections, and where a solid yellow line or no-passing pennant is present on your side.

Move over or slow down for stopped emergency, tow, and maintenance vehicles displaying flashing lights; if you cannot change lanes safely, reduce speed and proceed with caution.

Headlights are required from 30 minutes after sunset to 30 minutes before sunrise, and whenever visibility is insufficient to see persons or vehicles 1,000 feet away, plus during rain, snow, fog, or smoke.

Nevada law prohibits driving with a blood alcohol concentration of 0.08% or higher (0.04% for commercial drivers, 0.02% for drivers under 21); implied consent means submitting to a chemical test when lawfully requested.

Texting while driving is prohibited for all drivers, and handheld cell phone use is prohibited; hands-free devices are permitted for adult drivers but novice drivers face stricter limits.

At an intersection with no signs or signals, the vehicle that arrives first has the right-of-way; if two vehicles arrive at the same time, the vehicle on the left yields to the vehicle on the right.

A vehicle turning left must yield to oncoming traffic going straight or turning right, and must also yield to pedestrians in the crosswalk it is entering.

A vehicle entering a roadway from a driveway, alley, private road, or parking lot must yield to all traffic already on the roadway, including bicycles.

When two vehicles approach from opposite directions and one is turning left while the other goes straight, the left-turning vehicle yields; when both turn left, each keeps to the left of the center line.

Pedestrians in a marked or unmarked crosswalk have the right-of-way; a driver must yield and may not pass a vehicle stopped at a crosswalk for a pedestrian.

At a four-way stop, the first vehicle to stop proceeds first; when vehicles stop at the same time, the driver on the right goes first, and a left-turning driver yields to a straight-through driver.

Emergency vehicles with sirens and flashing lights have the right-of-way; pull to the right edge of the roadway and stop until the vehicle has passed, and never follow within 500 feet.

A driver entering a roundabout yields to traffic already circulating in the circle; traffic inside the roundabout never yields to entering traffic.

Blind pedestrians using a white cane or guide dog always have the right-of-way at any crossing, and drivers must stop and remain stopped until the pedestrian has cleared the roadway.

Nevada's default maximum speed limits are 25 mph in business and residential districts, 15 mph in school zones during posted hours, and 65 mph on rural interstate highways unless posted otherwise.

The basic speed law requires driving at a speed that is reasonable and prudent for existing conditions; a posted limit is a maximum, not a target, so rain, ice, fog, or heavy traffic can make a lower speed the legal one.

Nevada's absolute speed limits mean that exceeding the posted limit is a violation regardless of conditions; there is no legal allowance for driving faster than the posted maximum.

Following distance should be at least three seconds in good conditions; add one second for each adverse factor such as rain, darkness, or a heavy load, and more on ice or snow.

Stopping distance equals perception distance plus reaction distance plus braking distance; total stopping distance rises with the square of speed, so doubling speed roughly quadruples braking distance.

Reduce speed before entering a curve, not during it, and slow further when the curve is posted with an advisory speed plate below the general limit.

Slow down and use lower gears on long downgrades to avoid brake fade; continuous braking on a steep grade can overheat brakes and cause loss of stopping ability.

Speed must be reduced when approaching a hill crest, a narrow bridge, a sharp curve, or any place where the view ahead is obstructed, and whenever a hazard requires a stop within the distance you can see.

Work zone speed limits are enforceable when posted, and fines are doubled for moving violations in marked work zones where workers are present.

Warning signs are yellow diamonds with black symbols; common examples include curve ahead, crossroad ahead, signal ahead, pedestrian crossing, and deer crossing.

Regulatory signs are white rectangles with black or red legends, such as speed limit, no U-turn, no right turn, keep right, and one-way arrows.

Guide signs are green with white lettering for destinations and distances; brown signs identify parks, historic sites, and recreation areas.

Construction and maintenance signs are orange diamonds; a flagger symbol or a worker symbol means slow down and be prepared to stop.

A circular yellow sign with an R and R indicates a railroad crossing ahead; a white X-shaped crossbuck marks the crossing itself.

A five-sided yellow school sign warns of a school zone or school crossing; slow to the posted school-zone limit when children are present or the zone is in effect.

A yellow diamond with a black arrow curving warns of a curve ahead; a plate showing a speed below the limit is an advisory speed, not a mandatory limit but a safe maximum for the curve.

A red circle with a diagonal slash means the action shown inside is prohibited; a red circle alone with a number indicates a maximum limit.

Interstate route markers are red, white, and blue shields; U.S. route markers are white shields; state route markers in Nevada are white with a blue outline and the state name.

A center left-turn lane marked with opposing arrows may be entered only a short distance before turning left; it may not be used for passing or for travel.

When a lane ends or merges, the vehicle in the through lane has the right-of-way; the merging driver must adjust speed and yield, using the turn signal.

Do not enter an intersection unless you can clear it; blocking an intersection during a red light is a violation, and you may not stop on railroad tracks or crosswalks.

Right turns on red are permitted after a full stop and yield to pedestrians and traffic unless a sign prohibits them; left turns on red are permitted only from a one-way street onto another one-way street.

U-turns are prohibited at intersections controlled by a signal, on a curve or hill, and where a sign prohibits them; check that the turn can be made without interfering with traffic.

When a traffic signal is dark or flashing red because of a power failure, treat the intersection as an all-way stop and proceed in turn.

Bicycles and motorcycles are entitled to a full lane; pass only when you can leave a safe distance and never squeeze past in the same lane.

Backing is permitted only when it can be done safely; check behind the vehicle, back slowly, and never back on a freeway or in an intersection.

Parking is prohibited within 15 feet of a fire hydrant, within 20 feet of a crosswalk or intersection, on a sidewalk, and in front of a driveway.

Directions from a police officer or authorized flagger override signs, signals, and markings; obey the officer's hand signals even if the light is green.

A green arrow means you may proceed in the direction of the arrow, and oncoming traffic is stopped; a green circle means proceed if clear, yielding to pedestrians and oncoming left-turners.

A steady red arrow prohibits movement in that direction; a flashing yellow arrow means you may turn in that direction after yielding to oncoming traffic and pedestrians.

When a signal shows a green light but the intersection is blocked by traffic, do not enter; wait behind the crosswalk or stop bar until space is available.

A pedestrian signal showing a steady upraised hand means do not start crossing; a flashing hand means finish crossing but do not begin.

At a yield sign, slow down and be prepared to stop; if traffic is approaching, stop and wait, and only proceed when the way is clear.

When an emergency vehicle approaches from behind, pull to the right and stop; if you are in an intersection, clear it first and then pull over.

At an uncontrolled T-intersection, traffic on the through road has the right-of-way, and the vehicle on the terminating road must yield before entering or crossing.

A driver who has already entered an intersection lawfully on a green light may complete the turn after the light turns red, but must yield to pedestrians and cross traffic.

Nevada uses absolute speed limits, so a citation may be issued for exceeding the posted limit even if conditions are ideal; the limit is not a defense.

Speed limits in school zones are 15 mph and are enforced when children are present or the zone is in effect as posted; fines are increased for violations in school zones.

The three-second rule is a minimum following distance: pick a fixed object ahead, and if you reach it before counting three seconds after the vehicle ahead passes it, you are too close.

On wet pavement, stopping distance can roughly double; on ice it can increase many times over, so reduce speed well before conditions require it.

Advisory speeds on yellow plates are recommended maximums for curves, ramps, and other hazards; exceeding one does not automatically violate a limit but can be unsafe and used as evidence of unreasonable speed.

Driving too slowly can also be a violation: a driver may not drive so slowly as to impede the normal and reasonable flow of traffic.

Speed affects crash severity: kinetic energy rises with the square of speed, so a small increase in speed produces a much larger increase in crash forces.

When towing a trailer or driving a large vehicle, lower speeds are required on downgrades and in curves, and posted limits for trucks may be lower than for passenger cars.

In fog, rain, or dust, use low-beam headlights and reduce speed so you can stop within the distance you can see ahead.

A solid white line across your lane at an intersection is a stop bar; stop before it, not on it, when a signal or sign requires a stop.

Two solid yellow lines may be crossed to make a left turn into a driveway or side road, but not to pass; a single broken yellow line on your side permits passing.

White arrows painted in a lane show the direction of travel for that lane; choose the correct lane before the intersection and do not change lanes inside it.

A yellow diamond with a black symbol is a warning; a yellow diamond with a black arrow and a speed plate is a curve warning with an advisory speed.

Green lights mean go if clear; yellow means the light is changing; red means stop. A flashing red is a stop sign, and a flashing yellow is a caution signal.

Lane-use control signals over freeway lanes use a red X for closed lanes and a green arrow for open lanes; a yellow X means the lane is about to close.

Crosswalk markings may be two parallel white lines or a series of wide white bars; pedestrians in either form have the right-of-way.

A painted curb means parking is restricted: red = no stopping, yellow = loading only, white = passenger pickup, blue = disabled parking, green = limited time.

Rumble strips, raised pavement markers, and chevron signs warn of curves or lane shifts; they supplement, not replace, the posted signs and limits.

Motorcyclists are entitled to the full lane; do not share a lane with a motorcycle, and check mirrors and blind spots before changing lanes.

When passing a bicycle, leave at least three feet of clearance where practicable and do not return to the lane until the bicycle is safely behind you.

Pedestrians have the right-of-way in crosswalks; when a vehicle is stopped at a crosswalk, do not pass it, because a pedestrian may be hidden in front of it.

Large trucks have large blind spots (no-zones) behind and beside them; if you cannot see the truck driver's mirrors, the driver cannot see you.

If your brakes fail, pump them, downshift to a lower gear, and use the parking brake gradually; if a tire blows, hold the wheel firmly and slow gradually without hard braking.

If you begin to skid, steer in the direction you want the front of the vehicle to go and avoid hard braking; on ice, ease off the accelerator.

In a crash, stop, render aid if you can, exchange information, and report the crash to law enforcement when required by law; leaving the scene of an injury crash is a felony.

If your vehicle stalls on railroad tracks, get everyone out and away from the tracks immediately, then call for help; do not remain in the vehicle.

Drivers must yield to pedestrians in crosswalks, and a pedestrian who has stepped into a crosswalk with the intent to cross has the right-of-way.

When turning at a signal, yield to pedestrians crossing the street you are turning into, even if you have a green light.

A driver must not stop or park on a crosswalk or sidewalk, because doing so forces pedestrians into traffic and blocks their right-of-way.

At a crosswalk with a flashing yellow beacon, slow down and yield to pedestrians in the crosswalk; the beacon does not stop traffic by itself.

Blind pedestrians using a white cane or guide dog have the right-of-way everywhere, including outside marked crosswalks.

When a school bus displays flashing red lights, stop and remain stopped until the lights are turned off; the only exception on a divided highway is traffic in the opposite direction.

Funeral processions have the right-of-way; do not cut into or pass through a procession unless directed by an officer.

When an emergency vehicle approaches, pull to the right and stop; if you are in an intersection, clear it first, then pull over.

At a roundabout, entering drivers yield to circulating traffic, and pedestrians in the crosswalk at each leg have the right-of-way over entering and exiting vehicles.

Total stopping distance = perception distance + reaction distance + braking distance; at 60 mph a typical total is about 300 feet on dry pavement, far more than the length of a football field.

Perception-reaction time is commonly about 1.5 seconds; at 60 mph that alone covers roughly 132 feet before the brakes are applied.

Braking distance increases with the square of speed: going from 30 to 60 mph roughly quadruples braking distance, not doubles it.

Nevada's posted limits include 25 mph in residential and business districts and 65 mph on rural interstates; always obey the posted sign over the general limit.

The basic speed law requires a speed reasonable for conditions; you may be cited for driving too fast for conditions even below the posted limit.

In a work zone with workers present, fines for moving violations are doubled, and the posted work-zone limit is enforceable.

Following too closely is a violation; use the three-second rule and increase the gap in rain, at night, or when following a large vehicle that blocks your view.

When entering a freeway, use the acceleration lane to match traffic speed and merge safely; do not stop at the end of the ramp unless traffic requires it.

On a long downgrade, select a lower gear before the descent and use engine braking to keep speed controlled, applying brakes intermittently rather than continuously.

Regulatory signs tell you what you must or must not do and are enforceable; warning signs alert you to conditions ahead and are not themselves commands.

A stop sign requires a full stop at the stop bar, crosswalk, or edge of the roadway, and you must yield to traffic and pedestrians before proceeding.

A yield sign requires slowing and stopping if necessary; rolling through a yield without checking is a common cause of intersection crashes.

A no-passing zone is marked by a solid yellow line on your side and often by a pennant-shaped sign; passing there is a violation regardless of whether traffic is visible.

A yellow diamond with a symbol of a pedestrian warns of a crossing ahead; a fluorescent yellow-green sign marks a school crossing or school zone.

An orange diamond with a worker symbol means road work ahead; slow down and be prepared for lane shifts, flaggers, and stopped equipment.

A blue sign with a white H or a wheelchair symbol marks a hospital or accessible facility; a blue sign with a gas pump marks services ahead.

A brown sign identifies a park, historic site, or recreation area; these are guide signs, not warnings, and do not change the speed limit.

At a flashing yellow arrow for a left turn, yield to oncoming traffic and pedestrians before turning; at a green arrow, oncoming traffic is stopped and you may proceed.

Nevada's per se limit is 0.08% BAC for drivers 21 and older, 0.04% for commercial drivers, and 0.02% for drivers under 21; a driver may also be convicted when impaired below those levels.

Implied consent means that by driving in Nevada you agree to a chemical test when lawfully arrested for DUI; refusing can lead to license revocation.

Texting and handheld cell phone use are prohibited while driving; a first offense carries fines and points, and repeat offenses carry greater penalties.

A driver under 18 may not use a wireless device while driving except in an emergency, and passenger restrictions apply during the first months of licensure.

Nevada uses a point system: accumulating too many points within a year leads to license suspension, and traffic school may be offered to reduce points.

Driving is a privilege, not a right; a license may be suspended for DUI, excessive points, failure to appear, or failure to maintain insurance.

Financial responsibility law requires liability insurance or another approved form of security; driving uninsured can result in registration suspension and fines.

Open containers of alcohol in the passenger area of a vehicle are prohibited, and a driver with any measurable alcohol can be arrested if impaired.

Fatigue impairs driving like alcohol; take a break every two hours or 100 miles on long trips, and do not rely on caffeine or open windows to stay awake.

At a two-way stop, traffic on the road without stop signs has the right-of-way; vehicles facing stop signs must stop and yield to cross traffic.

At an all-way stop, first to arrive goes first; if two arrive together, the driver on the right proceeds first, and left-turning drivers yield to straight-through traffic.

A left turn at a green light must yield to oncoming traffic and pedestrians; a left turn on a green arrow may proceed because oncoming traffic is stopped.

When merging onto a freeway, the entering driver yields to traffic already on the freeway and uses the acceleration lane to match speed.

When two lanes merge into one, the driver in the lane being merged into has the right-of-way; the driver whose lane ends must yield.

When a vehicle is already in an intersection completing a turn, other drivers should allow it to clear before proceeding, even if their light turns green.

At a T-intersection, traffic on the continuing road has the right-of-way; traffic on the road that ends must yield before entering or crossing.

A driver entering a roundabout yields to traffic already circulating; once inside, the driver has the right-of-way over entering vehicles.

If an emergency vehicle approaches while you are in an intersection, clear the intersection first, then pull to the right and stop.

In rain, reduce speed and increase following distance; hydroplaning can occur at highway speeds, and if it happens, ease off the accelerator and avoid hard braking.

In fog, use low-beam headlights, reduce speed, and increase following distance; high beams reflect off the fog and reduce visibility.

On ice or snow, accelerate and brake gently, leave extra following distance, and steer smoothly; bridges and overpasses freeze first.

In strong crosswinds, reduce speed and grip the wheel firmly, especially when driving a high-profile vehicle or towing a trailer.

At night, drive at a speed that lets you stop within the distance illuminated by your headlights; overdriving your headlights is a common cause of night crashes.

In a work zone, reduce speed, watch for flaggers and lane shifts, and leave extra space behind the vehicle ahead.

When approaching a hill crest or curve with limited sight distance, slow down before the hazard so you can stop for anything hidden beyond it.

When towing a trailer, reduce speed and allow more stopping distance; trailer sway is corrected by easing off the accelerator, not by hard braking.

If your vehicle begins to hydroplane, ease off the accelerator and steer straight until traction returns; do not brake hard or turn sharply.

A steady green light means proceed if the intersection is clear; you must still yield to pedestrians and to vehicles lawfully in the intersection.

A steady yellow light warns that the signal is changing to red; stop if you can do so safely, and do not speed up to beat the light.

A steady red light means stop before the stop bar or crosswalk and remain stopped until the light turns green or a permitted turn is made.

A flashing red light is a stop sign: stop completely, yield, and proceed when safe. A flashing yellow light means slow down and proceed with caution.

A red arrow means no movement in that direction; a green arrow means the movement is protected; a flashing yellow arrow means yield before turning.

A dark or failed signal should be treated as an all-way stop; proceed in turn after stopping and yielding.

A white diamond symbol marks an HOV lane, which may be restricted to vehicles with a specified number of occupants during posted hours.

A red X over a freeway lane means the lane is closed; a green arrow means it is open; a yellow X warns the lane is about to close.

Green paint or markings may indicate a bicycle lane; do not drive, stop, or park in a bike lane except when crossing it to turn or park where permitted.

Parking is prohibited within 15 feet of a fire hydrant, within 20 feet of a crosswalk or intersection, within 30 feet of a stop sign or signal, and on a sidewalk or in front of a driveway.

When parking on a hill facing downhill, turn the wheels toward the curb; facing uphill with a curb, turn them away from the curb; with no curb, turn them toward the edge of the road.

Passing on the right is permitted only when the vehicle ahead is turning left or when there are two or more lanes in your direction; never pass on the shoulder.

On a freeway, use the left lane for passing and keep right except when passing; slower traffic must stay in the right lanes.

Do not stop, park, or back up on a freeway; if you miss an exit, continue to the next one rather than reversing.

When entering a freeway, use the acceleration lane to reach traffic speed, signal, and merge into a gap; do not stop at the end of the ramp unless necessary.

When leaving a freeway, signal early and move into the deceleration lane before slowing; do not slow down in the through lanes.

When a school bus stops with red lights flashing on an undivided road, traffic in both directions must stop; on a divided highway, only traffic behind the bus must stop.

Move over or slow down for stopped emergency, tow, and maintenance vehicles with flashing lights; if you cannot change lanes, reduce speed and proceed with caution.

Drivers must yield to pedestrians in marked or unmarked crosswalks at intersections; a pedestrian who has begun crossing has the right-of-way.

When a vehicle is stopped at a crosswalk, do not pass it; a pedestrian may be crossing in front of it and hidden from your view.

When turning, yield to pedestrians crossing the street you are entering, even if you have a green light or a green arrow.

Bicycles on the roadway are vehicles with the same rights and duties as cars; yield to them as you would to another vehicle.

When passing a bicycle, leave at least three feet of clearance where practicable, and do not return to the lane until you can see the bicycle behind you.

Do not drive, stop, or park in a bike lane except when crossing it to turn or park where permitted; check for cyclists before opening a car door.

At a crosswalk with a flashing yellow beacon, slow down and yield to pedestrians; the beacon warns drivers but does not itself stop traffic.

Blind pedestrians using a white cane or guide dog have the right-of-way at all times, including outside marked crosswalks.

When a pedestrian is crossing with a walk signal, vehicles turning through the crosswalk must wait until the pedestrian has cleared their path.

Nevada's general speed limits include 25 mph in business and residential districts, 15 mph in school zones when in effect, and 65 mph on rural interstates unless posted otherwise.

The basic speed law requires a speed that is reasonable and prudent for conditions; a posted limit is a maximum, not a safe speed for every condition.

Nevada uses absolute speed limits, so exceeding the posted limit is a violation regardless of conditions; there is no legal allowance above the limit.

Following distance should be at least three seconds in good conditions, increased in rain, at night, or when following a large vehicle.

Total stopping distance includes perception, reaction, and braking distance; it grows with the square of speed, so higher speeds greatly increase stopping distance.

Reduce speed before entering a curve and before a hill crest where the view is limited; do not brake hard in the middle of a curve.

Driving too slowly can be a violation when it impedes the normal and reasonable flow of traffic; keep up with traffic within the posted limit.

In work zones with workers present, fines for moving violations are doubled, and the posted work-zone limit is enforceable.

On a long downgrade, use a lower gear and engine braking to control speed rather than riding the brakes, which can overheat and fail.

Octagon = stop; inverted triangle = yield; diamond = warning; vertical rectangle = regulatory; horizontal rectangle = guide; pennant = no-passing zone; round = railroad advance warning.

Red means stop, yield, or prohibition; yellow means warning; orange means construction; blue means motorist services; brown means recreation; green means guide or permitted movement; white means regulatory.

A red circle with a diagonal slash means the action shown is prohibited; a red circle with a number is a maximum limit.

A yellow diamond with a black symbol warns of a condition ahead; the symbol shows the hazard, and a plate below may add distance or advisory speed.

A crossbuck (white X) marks a railroad crossing; a round yellow sign with an R and R warns of the crossing ahead.

A five-sided yellow sign warns of a school zone or school crossing; slow to the posted limit when children are present or the zone is in effect.

A white rectangular sign with black lettering is regulatory and enforceable, such as speed limit, keep right, or no U-turn.

A green rectangular sign gives directions, distances, and destinations; a brown sign identifies parks, historic sites, and recreation areas.

An orange diamond warns of road work ahead; slow down and watch for flaggers, lane shifts, and stopped equipment.

Headlights are required from 30 minutes after sunset to 30 minutes before sunrise and whenever visibility is insufficient to see persons or vehicles 1,000 feet away.

Use low beams in fog, rain, or snow and when following another vehicle or meeting oncoming traffic; high beams are for open road with no oncoming traffic.

Turn signals must be given before turning or changing lanes and must be visible to other drivers for a reasonable distance before the maneuver.

Brake lights, headlights, taillights, and turn signals must be in working order; a broken light can lead to a citation and reduces your visibility to others.

Windshield wipers must be in good condition, and headlights must be on when wipers are required by weather; Nevada requires lights with wipers in storm conditions.

A vehicle must have a working horn, mirrors, and safety belts; child passengers under 6 years old and under 60 pounds must be in an appropriate child restraint.

Do not drive with a suspended or revoked license; doing so can lead to arrest, vehicle impoundment, and additional suspension.

Proof of insurance must be carried in the vehicle and shown to law enforcement on request; driving uninsured can result in registration suspension.

A cracked or obstructed windshield, a missing mirror, or an inoperative signal can make a vehicle unsafe and subject to a fix-it citation.

Emergency vehicles with sirens and flashing lights have the right-of-way; pull to the right edge of the road and stop until the vehicle has passed.

Never follow an emergency vehicle closer than 500 feet when it is responding to an emergency, and never park within 500 feet of a fire station driveway.

If you are in an intersection when an emergency vehicle approaches, clear the intersection first, then pull to the right and stop.

Move over or slow down for stopped emergency, tow, and maintenance vehicles displaying flashing lights; if you cannot change lanes, reduce speed and proceed with caution.

When a school bus displays flashing red lights, stop and remain stopped until the lights are off; on a divided highway, only traffic behind the bus must stop.

Funeral processions have the right-of-way; do not cut into or pass through a procession unless directed by an officer.

A flagger in a work zone has the authority to direct traffic; obey the flagger's signals even if they conflict with a sign or signal.

Directions from a police officer override signs, signals, and markings; obey the officer's hand signals even if the light is green.

A vehicle displaying a slow-moving vehicle emblem (orange triangle) travels at 25 mph or less; slow down and pass with care when safe.

Perception-reaction time is commonly about 1.5 seconds; at 60 mph that covers roughly 132 feet before the brakes are applied.

Total stopping distance = perception distance + reaction distance + braking distance; at 60 mph a typical total is about 300 feet on dry pavement.

Braking distance increases with the square of speed, so doubling speed roughly quadruples braking distance.

Use the three-second rule for following distance in good conditions and add at least one second for rain, darkness, or a heavy load.

In fog, use low beams and reduce speed so you can stop within the distance you can see; high beams reflect off the fog and reduce visibility.

On ice or snow, accelerate and brake gently, increase following distance, and remember that bridges and overpasses freeze first.

If you begin to hydroplane, ease off the accelerator and steer straight until traction returns; do not brake hard or turn sharply.

In strong crosswinds, reduce speed and grip the wheel firmly, especially in high-profile vehicles or when towing a trailer.

When towing a trailer, reduce speed and allow more stopping distance; correct trailer sway by easing off the accelerator rather than braking hard.

A solid yellow center line on your side means no passing; a broken yellow line on your side permits passing when safe. Double solid yellow means no passing in either direction.

A solid white line separates same-direction lanes or marks the right edge; you should not cross it except in an emergency or to turn where permitted.

A broken white line separates same-direction lanes and may be crossed to change lanes when safe.

A stop bar is a solid white line across your lane at an intersection; stop before it when required, not on it.

White arrows painted in a lane show the direction of travel; choose the correct lane before the intersection and do not change lanes inside it.

A white diamond marks an HOV lane, which may be restricted to vehicles with a specified number of occupants during posted hours.

A red X over a freeway lane means the lane is closed; a green arrow means it is open; a yellow X warns that the lane is about to close.

Crosswalk markings may be two parallel white lines or a series of wide white bars; pedestrians in either form have the right-of-way.

Green paint or markings may indicate a bicycle lane; do not drive, stop, or park in a bike lane except when crossing it to turn or park where permitted.

Do not enter an intersection unless you can clear it; blocking an intersection during a red light is a violation, and you may not stop on railroad tracks or crosswalks.

Right turns on red are permitted after a full stop and yield to pedestrians and traffic unless a sign prohibits them; left turns on red are permitted only from a one-way street onto another one-way street.

U-turns are prohibited at signal-controlled intersections, on curves or hills, and where a sign prohibits them.

When a traffic signal is dark or flashing red because of a power failure, treat the intersection as an all-way stop and proceed in turn.

A center left-turn lane may be entered only a short distance before turning left; it may not be used for passing or for travel.

When a lane ends or merges, the vehicle in the through lane has the right-of-way; the merging driver must adjust speed and yield.

Bicycles and motorcycles are entitled to a full lane; pass only when you can leave a safe distance and never squeeze past in the same lane.

Backing is permitted only when it can be done safely; check behind the vehicle, back slowly, and never back on a freeway or in an intersection.

Parking is prohibited within 15 feet of a fire hydrant, within 20 feet of a crosswalk or intersection, on a sidewalk, and in front of a driveway.

At an intersection with no signs or signals, the vehicle that arrives first has the right-of-way; if two arrive at the same time, the vehicle on the left yields to the vehicle on the right.

A vehicle turning left must yield to oncoming traffic going straight or turning right, and must also yield to pedestrians in the crosswalk it is entering.

A vehicle entering a roadway from a driveway, alley, private road, or parking lot must yield to all traffic already on the roadway, including bicycles.

When two vehicles approach from opposite directions and one is turning left while the other goes straight, the left-turning vehicle yields.

At a four-way stop, the first vehicle to stop proceeds first; when vehicles stop at the same time, the driver on the right goes first.

A driver entering a roundabout yields to traffic already circulating; traffic inside the roundabout never yields to entering traffic.

At an uncontrolled T-intersection, traffic on the through road has the right-of-way, and the vehicle on the terminating road must yield.

A driver who has already entered an intersection lawfully on a green light may complete the turn after the light turns red but must yield to pedestrians and cross traffic.

When two lanes merge into one, the driver in the lane being merged into has the right-of-way; the driver whose lane ends must yield.

Nevada's posted limits include 25 mph in business and residential districts, 15 mph in school zones when in effect, and 65 mph on rural interstates unless posted otherwise.

The basic speed law requires a speed reasonable for conditions; you may be cited for driving too fast for conditions even below the posted limit.

Nevada uses absolute speed limits, so exceeding the posted limit is a violation regardless of conditions.

In work zones with workers present, fines for moving violations are doubled, and the posted work-zone limit is enforceable.

Driving too slowly can be a violation when it impedes the normal and reasonable flow of traffic; keep up with traffic within the posted limit.

When approaching a hill crest, curve, or narrow bridge with limited sight distance, slow down before the hazard so you can stop for anything hidden.

At night, drive at a speed that lets you stop within the distance illuminated by your headlights; overdriving your headlights is a common cause of night crashes.

On a long downgrade, select a lower gear before the descent and use engine braking to keep speed controlled, applying brakes intermittently rather than continuously.

When towing a trailer or driving a large vehicle, lower speeds are required on downgrades and in curves, and posted limits for trucks may be lower than for passenger cars.

Warning signs are yellow diamonds with black symbols; common examples include curve ahead, crossroad ahead, signal ahead, pedestrian crossing, and deer crossing.

Regulatory signs are white rectangles with black or red legends, such as speed limit, no U-turn, no right turn, keep right, and one-way arrows.

A yellow diamond with a black arrow curving warns of a curve ahead; a plate showing a speed below the limit is an advisory speed for the curve.

A circular yellow sign with an R and R indicates a railroad crossing ahead; a white X-shaped crossbuck marks the crossing itself.

A five-sided yellow school sign warns of a school zone or school crossing; slow to the posted school-zone limit when children are present.

An orange diamond with a worker symbol means road work ahead; slow down and be prepared for lane shifts, flaggers, and stopped equipment.

A blue sign with a white H or wheelchair symbol marks a hospital or accessible facility; a blue sign with a gas pump marks services ahead.

A brown sign identifies a park, historic site, or recreation area; these are guide signs, not warnings, and do not change the speed limit.

A no-passing zone is marked by a solid yellow line on your side and often by a pennant-shaped sign; passing there is a violation regardless of whether traffic is visible.

Nevada requires safety belt use by the driver and all passengers, and children under 6 years old and under 60 pounds must be in an appropriate child restraint in the rear seat.

Nevada's per se limit is 0.08% BAC for drivers 21 and older, 0.04% for commercial drivers, and 0.02% for drivers under 21.

Implied consent means that by driving in Nevada you agree to a chemical test when lawfully arrested for DUI; refusing can lead to license revocation.

Texting and handheld cell phone use are prohibited while driving; hands-free devices are permitted for adult drivers but novice drivers face stricter limits.

Open containers of alcohol in the passenger area of a vehicle are prohibited, and a driver with any measurable alcohol can be arrested if impaired.

Fatigue impairs driving like alcohol; take a break every two hours or 100 miles on long trips, and do not rely on caffeine or open windows to stay awake.

Nevada uses a point system: accumulating too many points within a year leads to license suspension, and traffic school may be offered to reduce points.

Financial responsibility law requires liability insurance or another approved form of security; driving uninsured can result in registration suspension and fines.

A driver under 18 may not use a wireless device while driving except in an emergency, and passenger restrictions apply during the first months of licensure.

Directions from a police officer or authorized flagger override signs, signals, and markings; obey the officer's hand signals even if the light is green.

A green arrow means you may proceed in the direction of the arrow, and oncoming traffic is stopped; a green circle means proceed if clear, yielding to pedestrians and oncoming left-turners.

A steady red arrow prohibits movement in that direction; a flashing yellow arrow means you may turn in that direction after yielding to oncoming traffic and pedestrians.

When a signal shows a green light but the intersection is blocked by traffic, do not enter; wait behind the crosswalk or stop bar until space is available.

A pedestrian signal showing a steady upraised hand means do not start crossing; a flashing hand means finish crossing but do not begin.

At a yield sign, slow down and be prepared to stop; if traffic is approaching, stop and wait, and only proceed when the way is clear.

At a crosswalk with a flashing yellow beacon, slow down and yield to pedestrians in the crosswalk; the beacon does not stop traffic by itself.

When an emergency vehicle approaches from behind, pull to the right and stop; if you are in an intersection, clear it first and then pull over.

At a roundabout, entering drivers yield to circulating traffic, and pedestrians in the crosswalk at each leg have the right-of-way over entering and exiting vehicles.

When entering a freeway, use the acceleration lane to match traffic speed and merge safely; do not stop at the end of the ramp unless traffic requires it.

When leaving a freeway, signal early and move into the deceleration lane before slowing; do not slow down in the through lanes.

On a freeway, use the left lane for passing and keep right except when passing; slower traffic must stay in the right lanes.

Do not stop, park, or back up on a freeway; if you miss an exit, continue to the next one rather than reversing.

At night, drive at a speed that lets you stop within the distance illuminated by your headlights; overdriving your headlights is a common cause of night crashes.

In rain, reduce speed and increase following distance; hydroplaning can occur at highway speeds, and if it happens, ease off the accelerator and avoid hard braking.

In fog, use low-beam headlights, reduce speed, and increase following distance; high beams reflect off the fog and reduce visibility.

On ice or snow, accelerate and brake gently, leave extra following distance, and steer smoothly; bridges and overpasses freeze first.

In strong crosswinds, reduce speed and grip the wheel firmly, especially when driving a high-profile vehicle or towing a trailer.
