Question 1Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white rectangular sign with black lettering reads 'SPEED LIMIT 45'. What does this sign establish in Maine?

  1. The maximum lawful speed under normal conditions is 45 mph Correct answer.
  2. The speed limit applies only to trucks at 45 mph
  3. The minimum lawful speed is 45 mph
  4. The recommended speed for curves is 45 mph

Explanation

A white regulatory speed limit sign with black numerals sets the maximum lawful speed for that road under normal conditions. Unless a lower limit is posted for a specific class of vehicle, it applies to all traffic. Advisory speeds for curves appear on yellow warning signs, not white regulatory ones.

Question 2Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

You are driving on a Maine road posted 'SPEED LIMIT 55' and heavy fog reduces visibility to about 200 feet. What is the correct action?

  1. Slow below the posted limit to a speed safe for the reduced visibility Correct answer.
  2. Speed up to clear the foggy area more quickly
  3. Turn on high beams and keep 55 mph
  4. Maintain 55 mph because the posted limit is lawful in all weather

Explanation

Posted speed limits apply to normal conditions; rain, fog, ice, or heavy traffic require you to drive slower than the maximum. Maine's basic speed rule requires a speed that is reasonable and prudent for existing conditions. Exceeding the posted limit is never required, but staying under it is expected when visibility drops.

Question 3Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A black-on-white sign reads 'TRUCKS USE LOW GEAR'. What is the purpose of this regulatory sign?

  1. To limit trucks to the left lane on the grade
  2. To require trucks to downshift on a downgrade for braking control Correct answer.
  3. To prohibit trucks from using engine brakes
  4. To tell trucks they must exit at the next ramp

Explanation

This sign directs heavy vehicles to select a lower gear before descending a steep grade so engine braking helps control speed and prevents brake fade. It is a regulatory instruction aimed at commercial vehicles, not an exit or lane directive. Passenger cars generally are not bound by it.

Question 4Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign shows a black arrow curving left with a red circle and slash over it. What maneuver does this prohibit?

  1. A U-turn Correct answer.
  2. A left turn at the intersection
  3. A lane change to the left
  4. Passing on the left

Explanation

A U-turn prohibition sign uses a curved arrow that reverses direction, combined with the red circle and slash. A simple left-turn prohibition uses a straight or right-angle arrow instead. Lane changes and passing are controlled by different markings and signs.

Question 5Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white rectangular sign reads 'NO RIGHT TURN ON RED'. What does this require of a driver facing it?

  1. Treat the signal as a flashing yellow for right turns
  2. Stop and wait for the green light before turning right Correct answer.
  3. Yield to traffic and turn right after stopping
  4. Turn right only when a police officer directs

Explanation

Maine generally allows a right turn after stopping at a red light unless a sign prohibits it. Where this sign is posted, the driver must remain stopped until the signal turns green. Yielding and stopping is not enough when the turn itself is banned on red.

Question 6Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

On a two-lane road you see a 'NO PASSING ZONE' pennant sign on your side. What does it mean?

  1. Passing is prohibited in your direction until the zone ends Correct answer.
  2. Passing is prohibited only for trucks
  3. Passing is allowed only for slow-moving farm equipment
  4. Passing is prohibited in both directions for one mile

Explanation

The yellow pennant-shaped 'NO PASSING ZONE' sign marks the start of a stretch where passing is prohibited for traffic moving in that direction. It is typically paired with a solid yellow line on your side. Passing restrictions for the opposite direction are marked separately.

Question 7Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign shows a black arrow pointing straight ahead labeled 'ONLY' above your lane. What does it tell you?

  1. The lane is reserved for buses going straight
  2. You may turn or go straight from this lane
  3. You must continue straight from this lane Correct answer.
  4. The lane ends ahead and merges straight

Explanation

A lane-use sign with a straight arrow and the word ONLY designates that lane exclusively for through movement. Drivers who intend to turn must be in a different lane. Lane-use signs control mandatory movements at the intersection ahead.

Question 8Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A black-on-white sign reads 'ONE WAY' with an arrow pointing right. What does it indicate about the roadway to your right?

  1. Traffic on that roadway moves only in the direction of the arrow Correct answer.
  2. Traffic on that roadway must turn right at the next corner
  3. The right lane is for right turns only
  4. The roadway is closed to through traffic

Explanation

A ONE WAY sign marks a roadway where all traffic flows in a single direction, shown by the arrow. It does not require you to turn, and it does not designate a turn lane. Entering such a roadway against the arrow is unlawful.

Question 9Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'WEIGHT LIMIT 10 TONS'. Which vehicles does this restriction apply to?

  1. Only single-unit trucks, not tractor-trailers
  2. Any vehicle or combination whose total weight exceeds 10 tons Correct answer.
  3. Only vehicles carrying hazardous materials over 10 tons
  4. Only vehicles over 10 tons per axle

Explanation

A posted weight limit restricts the total gross weight of a vehicle or combination to the figure shown. It applies to all vehicles that exceed the limit, not a special class. Axle-weight limits are a separate restriction from a posted gross weight limit.

Question 10Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'CLEARANCE 12 FT 6 IN'. What should a driver of a tall vehicle do before proceeding?

  1. Confirm the vehicle's height, including any load, is under 12 feet 6 inches Correct answer.
  2. Proceed if the vehicle is under 14 feet
  3. Proceed because clearance signs are advisory
  4. Assume the sign applies only to the shoulder

Explanation

Clearance signs state the maximum height that can pass beneath an overpass or structure. Drivers must know the total height of the vehicle plus any roof load and avoid the structure if it exceeds the posted figure. Striking an overpass can cause serious injury and structural damage.

Question 11Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

You approach a sign reading 'NO TRUCKS' on a residential street. Which vehicle is prohibited?

  1. A passenger pickup used for personal errands
  2. A heavy commercial truck over the posted weight threshold Correct answer.
  3. A van used as a family vehicle
  4. A passenger car towing a small utility trailer

Explanation

A NO TRUCKS sign restricts heavy commercial vehicles, typically defined by weight or vehicle class, from using the road. Local delivery and passenger-type vehicles are usually exempt under the applicable definition. The restriction targets through truck traffic on streets not built for heavy loads.

Question 12Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign mounted beside a travel lane reads 'LEFT LANE MUST TURN LEFT'. What must a driver in that lane do?

  1. Merge right before the intersection
  2. Continue straight through the intersection
  3. Complete a left turn at the intersection Correct answer.
  4. Stop and wait for a gap in oncoming traffic before merging

Explanation

This lane-use sign makes the left turn mandatory for vehicles in the designated lane. Drivers who want to continue straight must move to another lane before the intersection. The sign is regulatory, so failing to turn from that lane is a violation.

Question 13Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign shows a black bicycle symbol with the word 'LANE' beneath it. What does this sign indicate?

  1. Bicycles are prohibited on this road
  2. Motor vehicles must share the lane with bicycles
  3. A lane designated for bicycle use Correct answer.
  4. A bicycle parking area ahead

Explanation

A bicycle lane sign designates a portion of the roadway for exclusive or preferential bicycle use. Motor vehicles generally may not drive in a marked bike lane. The sign does not ban bicycles or mark parking.

Question 14Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

You are driving in the left lane of a multi-lane highway and see a 'KEEP RIGHT EXCEPT TO PASS' sign. What does it require?

  1. Stay in the left lane at all times
  2. Drive in the right lane unless you are overtaking another vehicle Correct answer.
  3. Exit at the next right-hand ramp
  4. Yield to traffic entering from the right

Explanation

This sign enforces the rule that slower traffic keeps right and the left lane is reserved for passing. A driver lingering in the left lane without passing violates the instruction. It does not require an exit or affect merging traffic.

Question 15Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'DO NOT PASS' with a black symbol of two cars side by side. How does this differ from the pennant-shaped NO PASSING ZONE sign?

  1. The rectangular sign applies only to trucks, while the pennant applies to all vehicles
  2. The rectangular sign marks a specific short restriction, while the pennant marks the start of a no-passing zone Correct answer.
  3. The rectangular sign is advisory, while the pennant is regulatory
  4. The rectangular sign bans passing in both directions, while the pennant bans it only on curves

Explanation

The rectangular DO NOT PASS sign is placed at a specific location where passing is unsafe, such as before a hillcrest or curve. The yellow pennant marks the beginning of an extended no-passing zone for your direction. Both are regulatory in effect and apply to all vehicles.

Question 16Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A sign reads 'SPEED LIMIT 65' but a separate white sign below reads 'TRUCKS 55'. A truck driver should interpret this as:

  1. A 65 mph limit for trucks and 55 mph for cars
  2. A 55 mph minimum for trucks
  3. A 55 mph limit that applies only at night
  4. A 55 mph maximum for trucks and a 65 mph maximum for other vehicles Correct answer.

Explanation

A supplementary truck speed sign lowers the maximum speed for trucks below the general limit shown above it. The general 65 mph limit continues to apply to passenger vehicles. Truck drivers are bound by the lower posted figure at all times.

Question 17Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign at an intersection reads 'NO LEFT TURN' and another reads 'NO U-TURN'. A driver who wants to reverse direction should:

  1. Make a U-turn because only left turns are banned
  2. Stop in the intersection and wait for a gap
  3. Turn left and then make a U-turn immediately
  4. Continue ahead and find a lawful place to turn around Correct answer.

Explanation

When both left turns and U-turns are prohibited at an intersection, a driver cannot reverse direction there. The lawful approach is to continue and turn around at a location where the maneuver is permitted. Stopping in the intersection obstructs traffic and is unsafe.

Question 18Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'RIGHT LANE ENDS MERGE LEFT'. What does this sign tell a driver in the right lane?

  1. The right lane terminates ahead and traffic must merge into the left lane Correct answer.
  2. Right turns are prohibited ahead
  3. The left lane is ending and traffic must merge right
  4. The right lane is closed for construction only during daytime

Explanation

This lane-use sign warns that the right lane will end, requiring drivers in it to merge left. Drivers should adjust speed and find a gap rather than waiting until the lane runs out. The sign concerns lane termination, not turn restrictions.

Question 19Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A black-on-white sign reads 'BRIDGE WEIGHT LIMIT 6 TONS'. A driver of a 7-ton delivery truck sees no alternate route posted. What is the correct action?

  1. Cross because the limit applies only to tractor-trailers
  2. Cross only if no other vehicles are on the bridge
  3. Cross slowly to reduce stress on the bridge
  4. Do not cross the bridge and find a route that complies with the limit Correct answer.

Explanation

A posted bridge weight limit is a strict maximum; an overweight vehicle may not cross even slowly or alone. The driver must use an alternate route that can legally carry the load. Ignoring the limit risks structural failure and is a violation.

Question 20Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign shows a black arrow bending left with the word 'ONLY' and a red circle-slash over a straight arrow. What movement is required?

  1. A left turn is the only permitted movement from this lane Correct answer.
  2. A left turn is prohibited from this lane
  3. Either a left turn or straight ahead is permitted
  4. Straight ahead is the only permitted movement

Explanation

Combining a left-turn arrow with ONLY designates the lane exclusively for left turns. The slashed straight arrow reinforces that through movement is not allowed from this lane. Drivers intending to go straight must choose a different lane.

Question 21Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'NO PARKING ANY TIME'. Where does this restriction generally apply?

  1. Only during business hours on weekdays
  2. Only to commercial vehicles
  3. Only when snow removal is underway
  4. Along the curb or shoulder where the sign is posted, at all hours Correct answer.

Explanation

A NO PARKING ANY TIME sign prohibits parking at all hours along the section it governs. It is not limited to business hours, weather events, or vehicle type. Parking there can result in a citation or towing.

Question 22Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'STOP HERE ON RED'. What does it require at a signalized intersection?

  1. Proceed through the red light after slowing
  2. Stop only if a pedestrian is present
  3. Stop at the marked line before proceeding when the light is red Correct answer.
  4. Stop only when turning right

Explanation

This sign directs drivers to stop at the designated point when the signal is red, such as before a crosswalk or sensor loop. It clarifies where the stop must occur for the signal to detect the vehicle and for pedestrians to be protected. Proceeding on red without a lawful turn is not permitted.

Question 23Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'DO NOT ENTER' at a roadway entrance. What does it mean?

  1. The roadway is open only to bicycles
  2. The roadway is a one-way street in your direction
  3. Vehicles must stop and then may enter if clear
  4. Vehicles may not proceed into that roadway because traffic faces them Correct answer.

Explanation

A DO NOT ENTER sign marks the wrong-way entrance to a one-way road or an exit ramp where oncoming traffic travels toward you. Entering would put you head-on against traffic. The sign is not a stop-and-proceed instruction.

Question 24Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'MINIMUM SPEED 40'. A driver traveling at 35 mph in the left lane of a highway should:

  1. Turn on hazard lights and continue at 35 mph
  2. Stay in the left lane at 35 mph
  3. Move to the right lane or increase speed to at least 40 mph Correct answer.
  4. Stop on the shoulder until traffic clears

Explanation

A posted minimum speed requires traffic to maintain at least that speed where conditions allow. A driver unable or unwilling to do so should move right so faster traffic can pass. Traveling well below the minimum in a travel lane impedes traffic and can be cited.

Question 25Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'NO PASSING ON RIGHT'. When does this restriction matter most?

  1. When a school bus is loading children
  2. When you are driving in the left lane of a divided highway
  3. When you are entering a highway from an on-ramp
  4. When a vehicle ahead is preparing to turn left and you consider passing on the shoulder Correct answer.

Explanation

This sign prohibits overtaking on the right, often where a paved shoulder could tempt drivers to squeeze past a left-turning vehicle. Passing on the shoulder is unsafe and generally unlawful. The sign does not concern ramp merges or normal left-lane travel.

Question 26Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white rectangular sign reads 'SPEED LIMIT 45'. What does this sign establish on the roadway where it is posted?

  1. A suggested speed for curves and bad weather
  2. The minimum speed slower vehicles must maintain
  3. An advisory speed that drivers may exceed freely
  4. The maximum lawful speed under normal conditions Correct answer.

Explanation

A white rectangular sign with black lettering stating a speed limit sets the legal maximum speed for that stretch of road in favorable conditions. Driving faster than the posted number is a violation unless a separate hazard-specific advisory sign indicates otherwise.

Question 27Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

You are traveling on an interstate and pass a white sign reading 'SPEED LIMIT 70' followed by a smaller sign reading 'MINIMUM 40'. What do these two signs together require?

  1. Never drive slower than 70 mph in any lane
  2. Keep speed between 40 and 70 mph under normal conditions Correct answer.
  3. Treat 40 mph as the maximum in the right lane
  4. Drive exactly 55 mph as a compromise speed

Explanation

The upper sign sets the maximum lawful speed and the lower sign sets the minimum lawful speed for the same roadway. A driver must stay within that band unless conditions such as weather or traffic require slower travel for safety.

Question 28Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign shows a left-pointing arrow with the word 'ONLY' beneath it over the leftmost lane of a three-lane road. What does this sign require of a driver in that lane?

  1. Merge right because the lane is closing
  2. Continue straight or turn left as traffic allows
  3. Yield to oncoming traffic before proceeding
  4. Turn left at the upcoming intersection Correct answer.

Explanation

A lane-use sign combining a turn arrow with 'ONLY' means that lane is reserved for that single movement. A driver in the left lane must make the left turn and may not continue straight from that lane.

Question 29Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign above a lane shows a straight arrow and a curved right arrow side by side with no 'ONLY' wording. How should a driver in that lane interpret it?

  1. The lane requires a right turn at the next corner
  2. The lane will merge into the right lane ahead
  3. The lane is reserved for buses and right-turning trucks
  4. The lane permits either going straight or turning right Correct answer.

Explanation

When a lane-use sign shows two permitted movements without the word 'ONLY', drivers in that lane may perform either movement. The sign identifies allowed choices rather than compelling a single one.

Question 30Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'CENTER LANE LEFT TURN ONLY' above a two-way left-turn lane marked with shared arrows. Who is permitted to use that center lane?

  1. Drivers preparing to turn left from either direction Correct answer.
  2. Drivers making deliveries with hazard lights on
  3. Drivers who want to pass slower traffic ahead
  4. Drivers entering the roadway from a driveway

Explanation

A center two-way left-turn lane is reserved for vehicles preparing to turn left from either direction. It is a staging area for turns, not a travel or passing lane.

Question 31Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

You see a white sign reading 'ONE WAY' with an arrow pointing left on a street you intend to enter from the right. What does the sign tell you about traffic on that street?

  1. Traffic flows only to the left as viewed from your position Correct answer.
  2. Traffic may turn either way at the next intersection
  3. Traffic alternates direction depending on the hour
  4. Traffic flows only toward you on that street

Explanation

A 'ONE WAY' sign with an arrow shows the single direction in which all traffic on that roadway travels. Entering against the arrow would put you in the path of oncoming vehicles.

Question 32Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign at the entrance to a parking lot exit reads 'DO NOT ENTER' with a red circle. A driver leaving the lot sees this sign facing them. What does it mean?

  1. The driver must stop and wait for a green light
  2. The driver should honk before entering the roadway
  3. The roadway ahead is closed to all traffic at night
  4. The driver is facing wrong-way travel and must not proceed Correct answer.

Explanation

A 'DO NOT ENTER' sign marks a roadway or ramp that vehicles may not enter from that direction. Seeing one face-on means the driver is oriented against the intended flow and must turn around.

Question 33Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

On a two-lane road a white rectangular sign reading 'DO NOT PASS' is posted on your side. How does this rectangular sign differ in meaning from the 'NO PASSING ZONE' pennant?

  1. The rectangle permits passing if the road ahead is clear
  2. The rectangle applies only to trucks and buses
  3. The rectangle is advisory while the pennant is enforceable
  4. The rectangle marks a point restriction while the pennant marks a zone Correct answer.

Explanation

The rectangular 'DO NOT PASS' sign is typically posted at a specific location, while the pennant marks the beginning of an extended no-passing zone. Both carry the force of law, but they differ in how the restriction is bounded.

Question 34Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign mounted beside a lane reads 'NO PASSING ON RIGHT'. In which situation does this restriction matter most?

  1. When you approach a bridge with a narrow span
  2. When a school bus stops with red lights flashing
  3. When a slow vehicle ahead moves to the left lane Correct answer.
  4. When a large truck ahead blocks your view

Explanation

The restriction matters most when a slower vehicle shifts left and tempts following drivers to squeeze past on the right. Passing on the right in that situation is prohibited by the sign and is unsafe because the left vehicle may return to the right lane.

Question 35Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'TRUCKS USE LOW GEAR' on a long downhill grade. What is the purpose of this regulatory instruction?

  1. To keep trucks below the minimum speed limit
  2. To reduce brake fade by using engine braking on the descent Correct answer.
  3. To prevent trucks from using the left lane
  4. To require trucks to shift into higher gears for economy

Explanation

On steep downgrades trucks can overheat their brakes if they rely on them continuously. Using a low gear lets engine compression control speed and preserves the service brakes for emergencies.

Question 36Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'WEIGHT LIMIT 8 TONS PER AXLE'. A driver of a vehicle with a registered gross weight of 14 tons spread over two axles should conclude what?

  1. The vehicle is prohibited because total weight exceeds 8 tons
  2. The vehicle may proceed because the sign limits only single-unit trucks
  3. The vehicle must reduce speed to 8 mph over the bridge
  4. The vehicle may proceed if each axle carries no more than 8 tons Correct answer.

Explanation

A per-axle weight limit restricts the load carried by each axle rather than the total vehicle weight. A 14-ton two-axle vehicle averaging 7 tons per axle is within an 8-ton per-axle limit.

Question 37Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'HEIGHT LIMIT 13 FT 6 IN' posted before an underpass. A driver whose vehicle is 14 feet tall should do what?

  1. Proceed because the sign applies only to commercial trucks
  2. Stop and use an alternate route that avoids the underpass Correct answer.
  3. Lower tire pressure to reduce overall height
  4. Proceed slowly and check clearance visually

Explanation

A posted height limit means vehicles taller than the stated clearance cannot safely pass beneath the structure. The driver must find another route rather than risk a bridge strike.

Question 38Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'NO TRUCKS OVER 4 TONS' on a residential street. A driver of a 3-ton pickup with a ladder rack should interpret the sign how?

  1. The truck may use the street only during daylight hours
  2. The truck must obtain a permit before entering the street
  3. The truck may use the street because it is under the weight threshold Correct answer.
  4. The truck is prohibited because it is a commercial vehicle

Explanation

This restriction combines a vehicle type with a weight threshold, so only trucks exceeding 4 tons are barred. A 3-ton truck falls below the stated limit and is not prohibited by this sign.

Question 39Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'RIGHT LANE MUST TURN RIGHT' at an intersection. A driver in the right lane who intended to continue straight should have done what?

  1. Signaled and proceeded straight from the right lane
  2. Stopped in the right lane and waited for a gap
  3. Backed up to re-enter the correct lane
  4. Changed lanes earlier to a lane that continues straight Correct answer.

Explanation

A mandatory turn sign means the lane's traffic must make the indicated movement, so a driver wanting to go straight needs a different lane. The proper action is to change lanes before reaching the intersection.

Question 40Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'LEFT TURN YIELD ON GREEN' at a signalized intersection. What does this instruct a left-turning driver to do?

  1. Wait for a green arrow before turning left
  2. Turn left only when the light is red
  3. Stop completely before every left turn
  4. Turn left after yielding to oncoming traffic and pedestrians Correct answer.

Explanation

This sign tells drivers that the left-turn movement is permitted on a circular green but is unprotected. The turning driver must yield to oncoming vehicles and to pedestrians in the crosswalk.

Question 41Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'NO TURN ON RED' beneath a traffic signal. What does this sign change about a driver's normal right-turn-on-red privilege?

  1. The driver may still turn right after yielding to traffic
  2. The driver must wait for a green light before turning right Correct answer.
  3. The driver may turn right only if no pedestrians are present
  4. The driver may turn right after coming to a rolling stop

Explanation

A 'NO TURN ON RED' sign removes the usual permission to turn right after stopping at a red light. The driver must remain stopped until the signal turns green.

Question 42Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'NO U TURN' at a median opening on a divided highway. A driver who missed an exit and wants to reverse direction should do what?

  1. Continue to the next legal interchange or turn-around Correct answer.
  2. Use the median crossover with hazard lights on
  3. Stop in the median and wait for a gap in traffic
  4. Make the U-turn only if no traffic is visible

Explanation

A 'NO U TURN' sign prohibits reversing direction at that location because sight lines or traffic patterns make it hazardous. The lawful choice is to continue to an interchange or designated turn-around where the maneuver is permitted.

Question 43Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'KEEP RIGHT' mounted on a traffic island at a fork in the road. What does this sign direct a driver to do?

  1. Pass the island on its right side Correct answer.
  2. Turn around and take the other branch
  3. Merge left into the opposing lane
  4. Stop before the island and yield

Explanation

A 'KEEP RIGHT' sign directs traffic to pass to the right of an island, divider, or obstacle. It separates opposing flows and prevents drivers from cutting across the wrong side.

Question 44Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'TWO-WAY TRAFFIC AHEAD' at the end of a divided highway segment. What should a driver expect and do?

  1. Expect the speed limit to drop to 25 mph
  2. Expect a mandatory stop at a checkpoint ahead
  3. Expect oncoming vehicles in what had been a one-direction roadway Correct answer.
  4. Expect the road to narrow to a single lane soon

Explanation

This regulatory sign warns that the roadway ahead carries traffic in both directions, often after a divided section. Drivers should keep right and be alert for oncoming vehicles that were previously separated by a median.

Question 45Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'SOFT SHOULDER' along a highway. What does this regulatory warning tell a driver about the area beyond the pavement edge?

  1. The shoulder is paved and safe for parking
  2. The shoulder has a rumble strip for alertness
  3. The shoulder surface may not support vehicle weight Correct answer.
  4. The shoulder is reserved for emergency vehicles

Explanation

A 'SOFT SHOULDER' sign warns that the ground beside the pavement may be unstable and unable to bear a vehicle's weight. Drivers should avoid pulling onto it, especially heavy vehicles that could sink or roll over.

Question 46Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'BRIDGE FREEZES BEFORE ROADWAY'. What action should a driver take when crossing the bridge in cold weather?

  1. Reduce speed and avoid sudden braking or steering Correct answer.
  2. Shift into neutral to coast across the bridge
  3. Maintain speed because the bridge is treated first
  4. Turn on hazard lights and stop on the bridge

Explanation

Bridge decks lose heat faster than the road surface and can ice while the approach is still clear. Slowing down and making smooth inputs reduces the chance of losing traction on unexpected ice.

Question 47Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'NO PARKING 7 AM TO 9 AM' on a city street. What does this restriction require of a driver?

  1. The driver may not leave the vehicle standing there during those hours Correct answer.
  2. The driver must move the vehicle every thirty minutes all day
  3. The driver may park there only on weekends
  4. The driver may park there if the engine is left running

Explanation

A time-limited parking restriction prohibits leaving a vehicle in that space during the stated hours. Outside those hours parking may be permitted unless another sign says otherwise.

Question 48Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'STOP HERE ON RED' beside a stop line at a signalized intersection. What does it require?

  1. Bring the vehicle to a full stop at the marked line when the light is red Correct answer.
  2. Stop at the sign rather than at the signal
  3. Stop only if pedestrians are present
  4. Stop before turning right on red

Explanation

This sign positions the stop line for red-light compliance, often where the signal is hard to see. Drivers must halt with the front of the vehicle at the marked line and remain there until the light changes.

Question 49Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'MINIMUM SPEED 45' in the left lane of a freeway. A driver traveling at 40 mph in that lane should do what?

  1. Stop on the shoulder until traffic clears
  2. Continue at 40 mph because minimums are advisory
  3. Speed up to at least 45 mph or move to a lane where slower travel is allowed Correct answer.
  4. Flash headlights to warn faster drivers behind

Explanation

A posted minimum speed means travel slower than that figure impedes traffic flow and is unlawful in that lane under normal conditions. A driver unable to maintain the minimum should move to a lane where slower speeds are permitted or exit the freeway.

Question 50Regulatory Signs (speed limits, lane use, turns, one-way, no-passing, weight and height limits)

A white sign reads 'NO RIGHT TURN ON RED' at an intersection where a driver wants to turn right. The light is red and the cross street is empty. What must the driver do?

  1. Turn right after yielding to pedestrians only
  2. Turn right after a full stop because traffic is clear
  3. Remain stopped until the light turns green Correct answer.
  4. Turn right slowly without stopping

Explanation

The sign removes the right-turn-on-red privilege entirely, so an empty cross street does not authorize the turn. The driver must wait for a green signal before proceeding.
