Question 1Driving Safely

Under Nevada rules, when must a driver use the vehicle's headlights?

  1. Only on roads posted with a lighting requirement sign
  2. Only between midnight and sunrise
  3. Whenever there is not enough light to clearly see persons or vehicles at 1,000 feet Correct answer.
  4. Only when it is actually raining or snowing

Explanation

Nevada requires headlights whenever insufficient light or unfavorable atmospheric conditions prevent clear visibility of persons and vehicles at a distance of 1,000 feet. Headlights are also required from 30 minutes after sunset until 30 minutes before sunrise. The visibility standard, not a clock time or posted sign, is what governs.

Question 2Driving Safely

When a school bus is stopped with its red lights flashing on a two-lane road, what must a driver approaching from the opposite direction do?

  1. Stop only if children are visible in the roadway
  2. Slow to 25 mph and continue past the bus
  3. Stop and remain stopped until the red lights stop flashing Correct answer.
  4. Sound the horn and pass with caution

Explanation

On a two-lane road, traffic in both directions must stop for a school bus displaying flashing red lights. The stop continues until the red lights are turned off. Passing a stopped school bus with red lights flashing is a serious violation.

Question 3Driving Safely

What is the recommended way to hold the steering wheel for normal driving?

  1. One hand at the top of the wheel
  2. Both hands on the lower half of the wheel
  3. Left hand at 9 o'clock and right hand at 3 o'clock Correct answer.
  4. Left hand between 7 and 8 o'clock, right hand between 4 and 5 o'clock

Explanation

The 9 and 3 o'clock position gives the best control and keeps the hands clear of the airbag. It also allows quick, balanced steering corrections. Hands at the top or bottom of the wheel reduce control and increase injury risk if the airbag deploys.

Question 4Driving Safely

A driver's vehicle begins to skid on a wet road. What is the correct first response?

  1. Accelerate to pull the vehicle out of the skid
  2. Turn the wheel sharply opposite the direction of the skid
  3. Take your foot off the accelerator and steer in the direction you want the front of the vehicle to go Correct answer.
  4. Brake hard and hold the wheel straight

Explanation

When a vehicle skids, easing off the accelerator lets the tires regain traction. Steering in the direction you want the front of the vehicle to go helps align the vehicle with the intended path. Hard braking or abrupt steering typically makes the skid worse.

Question 5Driving Safely

What following distance should a driver maintain behind the vehicle ahead under ideal conditions?

  1. At least six seconds
  2. At least one second
  3. At least two seconds Correct answer.
  4. At least four seconds

Explanation

Under ideal conditions, a driver should stay at least two seconds behind the vehicle ahead. The gap is measured by counting the time between the lead vehicle passing a fixed object and your vehicle reaching it. More time is needed at higher speeds or in poor conditions.

Question 6Driving Safely

A driver is following a large truck. How does the required following distance change?

  1. It can be shorter because the truck blocks the wind
  2. It can be shorter because trucks stop faster than cars
  3. It stays the same as for a passenger car
  4. It should be increased so the driver can see around the truck and have room to stop Correct answer.

Explanation

Large trucks block the view ahead, so following farther back lets the driver see traffic and road conditions past the truck. Trucks also need longer stopping distances, so extra space protects against sudden slowdowns. A larger gap is the safe choice.

Question 7Driving Safely

When may a driver legally pass another vehicle on the right on a multi-lane highway?

  1. Only when the speed limit is 65 mph or higher
  2. Never, under any circumstances
  3. Only when the vehicle ahead is making a left turn or when there are two or more lanes in the same direction Correct answer.
  4. Only when the shoulder is paved

Explanation

Passing on the right is generally allowed when the vehicle ahead is turning left or when the road has two or more lanes traveling in the same direction. Passing on the right must still be done safely and without leaving the roadway. Passing on an unpaved shoulder is never permitted.

Question 8Driving Safely

What is the safest action when an oncoming vehicle's headlights are blinding the driver at night?

  1. Flash high beams repeatedly until the other driver dims theirs
  2. Close your eyes briefly until the vehicle passes
  3. Look toward the right edge of your lane and slow down Correct answer.
  4. Speed up to pass the vehicle quickly

Explanation

Looking toward the right edge of the lane helps the driver stay in the lane while avoiding the glare. Slowing down gives more time to react if the vehicle drifts into your lane. Flashing lights or speeding up increases risk.

Question 9Driving Safely

How should a driver use high beams when following another vehicle at night?

  1. Dim to low beams when within 200 feet of the vehicle ahead Correct answer.
  2. Use high beams only when the vehicle ahead is more than 500 feet away
  3. Keep high beams on at all times to see farther
  4. Use high beams only in rain or fog

Explanation

High beams must be dimmed when following another vehicle within 200 feet, because the bright light reflects in the driver's mirrors. High beams are also dimmed for oncoming traffic within 500 feet. Using low beams in poor weather reduces glare back at the driver.

Question 10Driving Safely

A driver approaches a steady yellow traffic light. What does the light mean?

  1. Stop if it is safe to do so Correct answer.
  2. Speed up to clear the intersection before red
  3. Proceed because the light is about to turn green
  4. Stop only if pedestrians are present

Explanation

A steady yellow light warns that the signal is changing to red. The driver should stop if it is safe to do so. If stopping abruptly would cause a crash, the driver may proceed through the intersection with caution.

Question 11Driving Safely

What does a flashing red traffic light require a driver to do?

  1. Stop, yield, and proceed when safe Correct answer.
  2. Stop and wait for a police officer to direct traffic
  3. Treat it as a green light
  4. Slow down and proceed without stopping

Explanation

A flashing red light functions like a stop sign. The driver must come to a complete stop, yield to other traffic and pedestrians, and proceed only when it is safe. Waiting for an officer is not required.

Question 12Driving Safely

When two vehicles arrive at an uncontrolled intersection at about the same time, which vehicle has the right of way?

  1. The larger vehicle
  2. The vehicle on the right Correct answer.
  3. The vehicle traveling faster
  4. The vehicle on the left

Explanation

At an uncontrolled intersection, the vehicle on the right has the right of way when two vehicles arrive at about the same time. The driver on the left must yield. Size and speed do not determine right of way.

Question 13Driving Safely

A driver intends to turn left at an intersection with a solid green light. What must the driver do?

  1. Yield to oncoming traffic and pedestrians before turning Correct answer.
  2. Sound the horn and turn
  3. Wait for a green arrow before turning in any case
  4. Turn immediately because the light is green

Explanation

A solid green light allows a left turn only after yielding to oncoming traffic and pedestrians. The driver must wait for a safe gap. A green arrow, when present, gives a protected turn.

Question 14Driving Safely

How should a driver signal a lane change?

  1. Signal only if other vehicles are nearby
  2. Signal at least 100 feet before the change and check mirrors and blind spots Correct answer.
  3. Signal only after starting to move into the new lane
  4. Use hand signals instead of turn signals at all times

Explanation

Nevada requires a turn signal at least 100 feet before a lane change or turn. The driver should also check mirrors and blind spots to confirm the lane is clear. Signaling after moving defeats the purpose of warning others.

Question 15Driving Safely

What is the primary purpose of checking blind spots before a lane change?

  1. To check the road surface for potholes
  2. To estimate the distance to the next exit
  3. To confirm the turn signal is working
  4. To see vehicles that mirrors do not show Correct answer.

Explanation

Mirrors leave areas beside and behind the vehicle that they cannot show. A quick head check over the shoulder reveals vehicles in those blind spots. This check prevents sideswipe collisions during lane changes.

Question 16Driving Safely

A driver is entering a freeway from an on-ramp. What is the correct procedure?

  1. Merge immediately at ramp speed
  2. Use the acceleration lane to match the speed of freeway traffic and merge when safe Correct answer.
  3. Stop at the end of the ramp and wait for a large gap
  4. Drive on the shoulder until a gap appears

Explanation

The acceleration lane lets the driver build speed to match freeway traffic before merging. Merging at a similar speed reduces the risk of a rear-end collision. Stopping at the end of the ramp is dangerous unless traffic is stopped.

Question 17Driving Safely

When driving down a long, steep grade, what is the safest way to control speed?

  1. Ride the brakes continuously
  2. Shift to a lower gear and use the brakes intermittently Correct answer.
  3. Shift to neutral and coast
  4. Turn off the engine to save fuel

Explanation

A lower gear uses engine braking to help control speed on a downgrade. The brakes are then used intermittently, which prevents overheating and brake fade. Coasting in neutral or with the engine off removes control.

Question 18Driving Safely

A driver's vehicle has antilock brakes. During a panic stop, what should the driver do?

  1. Release the brake if the pedal pulses
  2. Brake lightly and steer sharply
  3. Pump the brake pedal rapidly
  4. Press the brake pedal firmly and hold it Correct answer.

Explanation

With antilock brakes, the driver should press the pedal firmly and hold it while steering. The system prevents wheel lockup and the pedal may pulse, which is normal. Pumping the pedal defeats the antilock function.

Question 19Driving Safely

How does alcohol affect a driver's ability to drive safely?

  1. It reduces judgment, coordination, and reaction time Correct answer.
  2. It affects only drivers who feel intoxicated
  3. It has no effect below the legal limit
  4. It improves reaction time at low doses

Explanation

Alcohol impairs judgment, coordination, and reaction time even at low levels. These effects begin before a driver feels intoxicated or reaches the legal limit. Any alcohol before driving increases crash risk.

Question 20Driving Safely

A driver is taking a prescription medication that causes drowsiness. What should the driver do?

  1. Drink coffee and drive as usual
  2. Drive only on roads with light traffic
  3. Ask the doctor or pharmacist about driving effects and avoid driving if impaired Correct answer.
  4. Take half the dose and drive

Explanation

Prescription drugs can impair driving just as alcohol does. The driver should ask the doctor or pharmacist whether the medication affects driving. If drowsiness occurs, the driver should not drive.

Question 21Driving Safely

What is the best way to stay alert on a long trip?

  1. Stop every two hours or 100 miles to rest and stretch Correct answer.
  2. Open a window and turn up the radio
  3. Drink energy drinks instead of stopping
  4. Drive straight through to save time

Explanation

Regular rest stops every two hours or 100 miles help prevent fatigue. Getting out and stretching restores alertness. Tricks like open windows or loud music do not fix fatigue.

Question 22Driving Safely

A driver feels sleepy while driving at night. What is the safest action?

  1. Turn on high beams and keep driving
  2. Speed up to arrive sooner
  3. Roll down the window and continue
  4. Continue to the next exit and pull over to rest Correct answer.

Explanation

Drowsiness is a serious impairment that can lead to falling asleep at the wheel. The safest response is to stop at a safe location and rest. Pushing on to the destination risks a crash.

Question 23Driving Safely

What is the correct action when an emergency vehicle approaches with its siren and lights on?

  1. Continue at the same speed in the left lane
  2. Stop in the middle of the intersection
  3. Pull to the right edge of the road and stop until it passes Correct answer.
  4. Speed up to stay ahead of it

Explanation

Drivers must yield to emergency vehicles using lights and sirens. Pulling to the right edge and stopping clears a path. Stopping in an intersection blocks the emergency vehicle's route.

Question 24Driving Safely

A tire blows out while a driver is traveling at highway speed. What should the driver do first?

  1. Turn sharply onto the shoulder
  2. Brake hard immediately
  3. Hold the wheel firmly and ease off the accelerator Correct answer.
  4. Accelerate to stabilize the vehicle

Explanation

After a blowout, the driver should grip the wheel firmly and ease off the accelerator to slow gradually. Hard braking or sharp steering can cause a loss of control. The vehicle should be guided to a safe stop once it is stable.

Question 25Driving Safely

Why is it dangerous to drive through moving water across a roadway?

  1. It only affects large trucks
  2. It only damages the tires
  3. It always improves traction
  4. Moving water can sweep a vehicle off the road even when shallow Correct answer.

Explanation

Flowing water exerts force against the vehicle and can float or sweep it off the roadway. Even shallow moving water can be powerful enough to move a car. Drivers should turn around rather than drive through flooded roads.

Question 26Driving Safely

Under New York's point system, what happens when a driver accumulates 11 points within 18 months?

  1. The driver's license is suspended after a hearing opportunity Correct answer.
  2. The driver pays a fine with no further action
  3. The driver receives only a written warning
  4. The driver must retake the written permit test

Explanation

New York assesses points for convictions, and reaching 11 points in an 18-month period triggers a suspension after the driver is offered a DMV hearing. Points are reduced by completing an approved accident-prevention course.

Question 27Driving Safely

A driver is convicted of following another vehicle too closely. How many points does New York assign for that conviction?

  1. Two points
  2. Three points
  3. Four points Correct answer.
  4. Six points

Explanation

New York assigns four points for a following-too-closely conviction, the same weight as speeding 21 to 30 mph over the limit. Point values are listed in the DMV point schedule.

Question 28Driving Safely

How many points does a New York driver receive for a conviction of reckless driving?

  1. Eleven points
  2. Three points
  3. Eight points
  4. Five points Correct answer.

Explanation

Reckless driving carries five points under New York's point schedule. It is a serious violation that can also lead to license suspension and higher insurance costs.

Question 29Driving Safely

A driver with a probationary license in New York is convicted of a serious traffic violation. What is a possible consequence?

  1. The probationary license may be suspended or revoked Correct answer.
  2. The driver's points are erased after 30 days
  3. The driver pays only a surcharge with no record
  4. The driver automatically receives a commercial license

Explanation

Probationary drivers face stricter consequences, and serious violations can lead to suspension or revocation of the probationary license. Points remain on the record and are not erased quickly.

Question 30Driving Safely

What is the maximum speed limit on most rural interstate highways in New York unless posted otherwise?

  1. 65 mph Correct answer.
  2. 70 mph
  3. 75 mph
  4. 55 mph

Explanation

New York's default maximum speed limit on rural interstates is 65 mph unless a different limit is posted. Drivers must always obey the posted limit, which may be lower.

Question 31Driving Safely

What is the speed limit in a New York school speed zone while the zone is in effect?

  1. 30 mph
  2. 25 mph Correct answer.
  3. 15 mph
  4. 20 mph

Explanation

New York sets school speed zones at 25 mph during the posted hours when the zone is active. The lower limit protects children near schools.

Question 32Driving Safely

A driver is convicted of speeding 25 mph over the posted limit. How many points does New York assign?

  1. Three points
  2. Four points
  3. Six points Correct answer.
  4. Eight points

Explanation

New York assigns six points for speeding 21 to 30 mph over the limit. Points increase as the amount over the limit grows.

Question 33Driving Safely

What does a steady green arrow pointing left mean for a driver turning left?

  1. The driver may turn only after the light turns red
  2. The driver must stop and wait for a flashing signal
  3. The left turn is protected and oncoming traffic is stopped Correct answer.
  4. The driver must yield to oncoming traffic before turning

Explanation

A green arrow gives a protected turn, meaning conflicting traffic is stopped. The driver may proceed with the turn while the arrow is displayed.

Question 34Driving Safely

A driver approaches a flashing yellow traffic signal. What should the driver do?

  1. Treat the signal as a stop sign
  2. Come to a complete stop before proceeding
  3. Wait for a green light before moving
  4. Slow down and proceed with caution Correct answer.

Explanation

A flashing yellow light warns drivers to slow down and proceed carefully while watching for hazards. It does not require a stop.

Question 35Driving Safely

What does a yellow diamond-shaped warning sign with a curved arrow indicate?

  1. A pedestrian crossing with a stop required
  2. A curve ahead that may require reduced speed Correct answer.
  3. A lane that ends ahead
  4. A mandatory U-turn location

Explanation

Yellow diamond signs are warnings, and a curved arrow warns of a curve ahead where the driver should slow down. Warning signs do not impose a stop requirement.

Question 36Driving Safely

A driver sees a sign with a red circle and a diagonal slash over a symbol. What does this sign mean?

  1. The action shown is optional
  2. The action shown is recommended
  3. The action shown is required
  4. The action shown is prohibited Correct answer.

Explanation

A red circle with a diagonal slash is a regulatory prohibition sign. It tells drivers that the depicted action is not allowed.

Question 37Driving Safely

A driver is approaching a railroad crossing with flashing red lights and no gate. What is the required action?

  1. Honk and continue across the tracks
  2. Stop and remain stopped until the lights stop flashing Correct answer.
  3. Proceed if the driver can cross before the train arrives
  4. Slow down and cross if no train is visible

Explanation

Flashing red lights at a railroad crossing require a complete stop until the lights stop flashing and it is safe to cross. Never try to beat a train.

Question 38Driving Safely

When a school bus displays flashing red lights on an undivided two-lane road, what must an approaching driver do?

  1. Pass only if children are not visible
  2. Stop only if the bus is on the same side
  3. Stop until the red lights stop flashing Correct answer.
  4. Slow down and pass with caution

Explanation

On an undivided road, traffic in both directions must stop for a school bus with flashing red lights. Drivers may proceed only after the lights stop.

Question 39Driving Safely

A driver is convicted of passing a stopped school bus with flashing red lights. What is a likely consequence in New York?

  1. Five points and a substantial fine Correct answer.
  2. No points if no children were present
  3. Only a written test requirement
  4. Two points and a warning

Explanation

Passing a stopped school bus with red lights flashing carries five points and significant fines in New York. The penalty applies even if no children were present.

Question 40Driving Safely

What is the proper way to make a right turn at a red light in New York, where permitted?

  1. Stop, yield to traffic and pedestrians, then turn when clear Correct answer.
  2. Stop and turn immediately without yielding
  3. Slow down and turn without stopping if clear
  4. Turn only after the light turns green

Explanation

A right turn on red is allowed after a complete stop, yielding to pedestrians and cross traffic. Some intersections prohibit the turn by sign.

Question 41Driving Safely

A driver is parking on a two-way street in New York. Which direction should the vehicle face?

  1. Against traffic to simplify leaving
  2. In the direction of traffic on that side Correct answer.
  3. Facing the nearest crosswalk
  4. Either direction as long as wheels are curbed

Explanation

Parked vehicles must face in the direction of traffic flow on that side of the street. Parking against traffic is unsafe and illegal.

Question 42Driving Safely

How close to a fire hydrant may a driver legally park in New York?

  1. No closer than 50 feet
  2. No closer than 25 feet
  3. No closer than 5 feet
  4. No closer than 15 feet Correct answer.

Explanation

New York prohibits parking within 15 feet of a fire hydrant so firefighters can access it. The distance is measured from the hydrant.

Question 43Driving Safely

A driver's vehicle begins to skid on a wet road. What should the driver do?

  1. Pull the parking brake firmly
  2. Ease off the accelerator and steer in the direction of the skid Correct answer.
  3. Brake hard and turn against the skid
  4. Accelerate to regain traction

Explanation

Easing off the accelerator and steering in the direction of the skid helps the tires regain traction. Hard braking or acceleration can worsen the skid.

Question 44Driving Safely

What is the recommended minimum following distance under normal driving conditions?

  1. At least one second
  2. At least three seconds Correct answer.
  3. At least ten seconds
  4. At least half a car length

Explanation

A three-second following distance gives the driver time to react under normal conditions. The gap should increase in bad weather or when following large vehicles.

Question 45Driving Safely

A driver is stopped at a red light behind another vehicle. How should the driver position the vehicle?

  1. Directly over the crosswalk line
  2. Far enough back to see the rear tires of the vehicle ahead Correct answer.
  3. In the oncoming lane to improve visibility
  4. Bumper to bumper to prevent others from cutting in

Explanation

Stopping where the rear tires of the vehicle ahead are visible leaves room to maneuver if that vehicle stalls. It also reduces the risk of a rear-end collision.

Question 46Driving Safely

What does a solid white line between lanes on a roadway indicate?

  1. The lane is reserved for buses
  2. Lane changes are discouraged Correct answer.
  3. Passing is required
  4. Traffic must merge immediately

Explanation

A solid white line discourages lane changes, while a broken white line permits them when safe. Solid lines are common near intersections and off-ramps.

Question 47Driving Safely

A driver's vehicle has a tire with low pressure and the warning light is on. What is the best action?

  1. Check the tires and inflate them to the recommended pressure Correct answer.
  2. Ignore the light if the vehicle drives normally
  3. Increase speed to seat the tire bead
  4. Continue driving until the next oil change

Explanation

Low tire pressure affects handling and fuel economy and can lead to a blowout. Checking and inflating to the recommended pressure addresses the problem.

Question 48Driving Safely

Under New York's Move Over law, what must a driver do when approaching a stopped emergency vehicle with lights flashing on a multi-lane road?

  1. Stop completely in the travel lane
  2. Move over a lane if safe or slow down significantly Correct answer.
  3. Maintain speed and stay in the lane
  4. Honk and pass in the same lane

Explanation

New York's Move Over law requires drivers to move over one lane when safe or slow down significantly when approaching stopped emergency or hazard vehicles with lights flashing.

Question 49Driving Safely

A driver is involved in a crash with property damage only in New York. What must the driver do?

  1. Stop, exchange information, and report if required Correct answer.
  2. Leave the scene if no one is injured
  3. Report only if the other driver requests it
  4. Continue driving and report at the next trip

Explanation

Drivers must stop after a crash, exchange required information, and report the crash when required by law. Leaving the scene can lead to serious charges.

Question 50Driving Safely

A driver's license is suspended for a DWI conviction. What is required before driving privileges may be restored?

  1. Nothing, since suspension ends automatically
  2. Payment of fees and proof of compliance with DMV requirements Correct answer.
  3. Only a written apology to the court
  4. A new vehicle purchase

Explanation
