Question 1North Carolina traffic laws, signs, signals, and markings

You are approaching a stop sign where a solid white stop line is painted across your lane. Where must the front of your vehicle come to a complete stop?

  1. Past the stop line, where cross traffic is visible
  2. At the marked stop line, before the crosswalk Correct answer.
  3. Even with the stop sign post
  4. At the far edge of the intersecting roadway

Explanation

North Carolina requires a complete stop at the marked stop line before entering a crosswalk or intersection. When no stop line exists, the stop is made at the crosswalk, and if there is no crosswalk, at the edge of the intersecting roadway. Rolling past the line to improve your view is a violation even if no traffic is present.

Question 2North Carolina traffic laws, signs, signals, and markings

Under North Carolina law, when may a driver make a right turn at a steady red light?

  1. After stopping, unless a sign prohibits it Correct answer.
  2. Only during a flashing red signal
  3. While slowing, if no traffic is approaching
  4. Only where a sign specifically allows the turn

Explanation

A right turn on red is permitted after a full stop, yielding the right of way to pedestrians and to traffic already in or approaching the intersection. The turn is forbidden wherever a sign prohibits it, and a flashing red signal simply functions as a stop sign at that point.

Question 3North Carolina traffic laws, signs, signals, and markings

A two-way street is marked down the center with two solid yellow lines. What do these lines indicate?

  1. Passing is prohibited for traffic in both directions Correct answer.
  2. The lane nearest each line is reserved for turning
  3. Traffic may cross the lines to pass a slow vehicle
  4. Passing is allowed for traffic on both sides

Explanation

Solid yellow lines separate traffic moving in opposite directions and signal a no-passing zone. When both lines are solid, neither direction may cross them to overtake. Drivers may still cross them where lawful to make a left turn into a driveway or side road.

Question 4North Carolina traffic laws, signs, signals, and markings

You are driving on a four-lane divided highway separated by a raised median. A school bus on the opposite side of the median stops with its red lights flashing and stop arm extended. What must you do?

  1. Stop only if children are visible near the roadway
  2. Stop until the stop arm is retracted
  3. Slow to 25 mph and continue past the bus
  4. Continue at your normal speed; the stop applies to traffic behind the bus Correct answer.

Explanation

On a highway divided by a median or other physical barrier, only traffic traveling in the same direction as the school bus must stop for its flashing red lights and stop arm. Opposing traffic on the other roadway is not required to stop, although drivers should still watch for children near the roadway.

Question 5North Carolina traffic laws, signs, signals, and markings

A law enforcement vehicle with flashing blue lights is stopped on the right shoulder of a four-lane road. What does North Carolina's Move Over law require of you?

  1. Reduce speed to 25 mph and remain in your current lane
  2. Move over one lane, or slow down if unable Correct answer.
  3. Stop completely until an officer signals you to proceed
  4. Change lanes only when the emergency vehicle is inside your travel lane

Explanation

The Move Over law requires a driver approaching a stopped emergency vehicle with its lights activated to vacate the lane closest to that vehicle when it is safe to do so. If traffic, road design, or weather make a lane change unsafe or impossible, the driver must slow down and pass with caution. The duty applies whenever emergency lights are operating, not only when the vehicle blocks a lane.

Question 6North Carolina traffic laws, signs, signals, and markings

Under North Carolina law, a child younger than 2 years must be secured in which type of restraint, unless the child exceeds the manufacturer's height or weight limit for that seat?

  1. A belt-positioning booster seat
  2. A rear-facing child restraint Correct answer.
  3. A standard lap and shoulder belt
  4. A forward-facing seat with a five-point harness

Explanation

North Carolina requires children under age 2 to ride in a rear-facing child passenger restraint system until they reach the seat manufacturer's height or weight limit. The requirement reflects the greater protection rear-facing seats give an infant's head and neck. Older children move to forward-facing seats and then to boosters as they outgrow each stage.

Question 7North Carolina traffic laws, signs, signals, and markings

You are stopped at a red light on a one-way street and want to turn left onto another one-way street. What does North Carolina law permit?

  1. No left turn on red is permitted under any circumstances at any intersection
  2. The turn without stopping if the street is clearly empty
  3. A left turn after stopping, yielding, unless posted otherwise Correct answer.
  4. The turn may be made only after the signal turns green

Explanation

A left turn on red is allowed only when both streets are one-way, and only after a complete stop with the right of way yielded to pedestrians and other traffic. Any posted sign prohibiting the turn controls. Turning from a two-way street onto a one-way street on red is not permitted.

Question 8North Carolina traffic laws, signs, signals, and markings

Which statement correctly describes North Carolina's rules on mobile phone use by a licensed driver who is 21 years old?

  1. Hands-free and handheld calls are both prohibited
  2. Sending or reading a text while driving is prohibited Correct answer.
  3. Handheld calls are permitted, but only on rural roads
  4. Texting is allowed while stopped at a red light

Explanation

North Carolina bans manually entering or reading text messages and emails for all drivers, regardless of age. The separate handheld phone ban applies to drivers under 18 and to school bus drivers, so a 21-year-old may legally make a handheld call but may not text. The texting prohibition is not suspended while the vehicle is stopped in traffic.

Question 9North Carolina traffic laws, signs, signals, and markings

In North Carolina, how many driver license points are assessed against a driver convicted of passing a stopped school bus?

  1. Five points Correct answer.
  2. Two points
  3. Eight points
  4. Twelve points

Explanation

A conviction for passing a stopped school bus carries five driver license points, one of the heaviest assessments in the state point schedule, along with misdemeanor penalties. Accumulating 12 points within three years results in license suspension. The high point value reflects the danger to children loading and unloading.

Question 10North Carolina traffic laws, signs, signals, and markings

A driver arrested for impaired driving refuses to submit to a chemical test. Under North Carolina's implied consent law, what is the consequence?

  1. The officer must release the driver without filing charges
  2. The driver may select a different test and avoid any penalty
  3. The refusal is ignored if the driver later performs well on field sobriety tests
  4. A one-year revocation, and the refusal may be used at trial Correct answer.

Explanation

By driving on North Carolina highways, a person consents to chemical testing when lawfully arrested for impaired driving. A willful refusal results in revocation of driving privileges for one year for a first refusal, and the refusal itself is admissible as evidence in the criminal case. Field sobriety test performance does not erase the refusal or its consequences.

Question 11North Carolina traffic laws, signs, signals, and markings

A driver facing a flashing yellow left-turn arrow in North Carolina may do which of the following?

  1. A turn that remains prohibited until a steady green arrow appears.
  2. A protected turn that gives you the right-of-way over oncoming traffic.
  3. A permissive turn after yielding to oncoming traffic and pedestrians. Correct answer.
  4. A required stop before you may turn left across oncoming traffic.

Explanation

A flashing yellow arrow authorizes a permissive left turn, not a protected one. The driver must yield to oncoming vehicles and to pedestrians in the crosswalk before completing the turn. A steady green arrow, by contrast, gives a protected turn.

Question 12North Carolina traffic laws, signs, signals, and markings

A center lane on a two-way street is bounded by yellow lines on both sides and is marked for left turns from either direction. Under North Carolina law, which use of this lane is permitted?

  1. Using it to pass a slower vehicle going the same direction.
  2. Entering to prepare for a left turn. Correct answer.
  3. Using it as a through lane when regular lanes are congested.
  4. Parking in it briefly while making a delivery.

Explanation

This is a two-way left-turn lane, provided so drivers from either direction can wait for a safe gap to turn left. It is not a travel lane, a passing lane, or a parking area. Entering it well before the turn is permitted; using it for other purposes is not.

Question 13North Carolina traffic laws, signs, signals, and markings

When a driver approaches a modern roundabout in North Carolina and sees no stop sign or traffic signal, what is the correct action?

  1. Yield only to vehicles that are approaching from your left side.
  2. Enter immediately because vehicles already circulating must yield to entering traffic.
  3. Come to a complete stop and wait until no vehicle is anywhere in the circle.
  4. Yield to circulating traffic and to pedestrians in the crosswalk. Correct answer.

Explanation

A roundabout is designed for continuous movement, and entering drivers must yield to vehicles already in the circle. They must also yield to pedestrians using the crosswalk at the entrance. Stopping when the circle is clear is unnecessary and can disrupt traffic flow.

Question 14North Carolina traffic laws, signs, signals, and markings

A school zone sign in North Carolina displays a 25 mph limit with yellow lights that flash before and after school. When must a driver obey the 25 mph limit?

  1. At all times, day or night, unless a sign says otherwise.
  2. Whenever the yellow lights are flashing. Correct answer.
  3. Only when children are visible along the sidewalk.
  4. Only during the hours the school building is open.

Explanation

North Carolina school zones commonly use flashing yellow lights to identify when the reduced speed limit is in force. Drivers must slow to the posted school-zone limit whenever the lights are flashing, not merely when they happen to see children. The regular speed limit resumes when the lights stop flashing.

Question 15North Carolina traffic laws, signs, signals, and markings

At a railroad crossing marked only by a crossbuck sign and no gates or flashing lights, what must a North Carolina driver do?

  1. Stop only if a flagger or another driver signals that a train is coming.
  2. Stop completely before the tracks every time, even when no train is near.
  3. Slow down, look and listen, and stop if a train is approaching. Correct answer.
  4. Continue at the posted speed because crossbucks apply only to trains.

Explanation

A crossbuck sign means the crossing is passive and the driver must yield to trains. The driver should slow down, look and listen, and stop when a train is approaching. A complete stop is required when a train is near, not every time regardless of conditions.

Question 16North Carolina traffic laws, signs, signals, and markings

An orange sign in a North Carolina work zone states that fines are doubled. When does that enhanced penalty apply?

  1. Only if the driver exceeds the posted limit by more than 15 mph.
  2. When workers are present in the work zone. Correct answer.
  3. At all times while the orange signs remain posted.
  4. Only during nighttime hours when workers are absent.

Explanation

North Carolina's enhanced work-zone penalties for speeding apply when workers are present in the zone. The orange signs warn drivers of the construction area and the possible doubled fine. When no workers are present, the enhanced penalty does not apply solely because signs remain.

Question 17North Carolina traffic laws, signs, signals, and markings

Two vehicles arrive at the same time at an intersection with no stop signs, yield signs, or traffic signals. What does North Carolina law require?

  1. The driver who is traveling faster has the right-of-way.
  2. The driver on the left must yield to the driver on the right. Correct answer.
  3. The driver on the right must yield to the driver on the left.
  4. Both drivers must stop and wait for a police officer.

Explanation

At an uncontrolled intersection, North Carolina follows the general rule that the driver on the left yields to the driver on the right. This rule applies when the vehicles arrive at approximately the same time. Speed does not create a right-of-way.

Question 18North Carolina traffic laws, signs, signals, and markings

A vehicle in the lane ahead of you is stopped at a marked crosswalk to let a pedestrian cross. What does North Carolina law require you to do?

  1. Sound your horn so the pedestrian hurries across the roadway.
  2. Pass the stopped vehicle on the left if the pedestrian is still on the far side.
  3. Move into the adjacent lane and continue without slowing down.
  4. Stop behind the vehicle and do not pass it while the pedestrian crosses. Correct answer.

Explanation

North Carolina prohibits passing a vehicle that is stopped at a crosswalk to allow a pedestrian to cross. The driver behind must stop and wait rather than go around the stopped vehicle. This protects the pedestrian, who may be hidden from the passing driver's view.

Question 19North Carolina traffic laws, signs, signals, and markings

On a divided highway, a solid yellow line painted along the far left edge of your travel lane marks what?

  1. The boundary of a two-way left-turn lane.
  2. The right edge of the roadway next to the shoulder.
  3. The left edge next to the median. Correct answer.
  4. A lane reserved for passing slower traffic.

Explanation

Yellow pavement markings separate traffic moving in opposite directions or mark the left edge of a divided roadway. A solid yellow line on the far left of a divided highway shows the edge next to the median. White lines generally mark the right edge or separate same-direction lanes.

Question 20North Carolina traffic laws, signs, signals, and markings

A traffic signal at an intersection is flashing red in all directions after a power failure. How should a North Carolina driver proceed?

  1. Proceed without stopping because the signal is not showing a steady red.
  2. Stop, yield to traffic in the intersection, and proceed when safe. Correct answer.
  3. Treat the signal as a yield sign and slow down only if traffic is present.
  4. Wait for the signal to turn green before entering the intersection.

Explanation

A flashing red signal requires each driver to stop and then proceed when it is safe, functioning like a stop sign. When all directions flash red, drivers treat the intersection as an all-way stop and yield to traffic already in it. Waiting for a green light is unnecessary because the signal may remain in flashing mode.

Question 21North Carolina traffic laws, signs, signals, and markings

Under North Carolina law, what is the default speed limit in a residential district unless a different speed is posted?

  1. 25 mph
  2. 35 mph Correct answer.
  3. 45 mph
  4. 55 mph

Explanation

North Carolina sets a statutory speed limit of 35 mph in residential districts and 55 mph in rural areas unless signs post a different limit. A lower posted limit, such as a school zone limit, controls when it is in effect. Drivers must always follow the posted or statutory limit for the area.

Question 22North Carolina traffic laws, signs, signals, and markings

A red octagonal sign with white lettering is posted at an intersection. What does this sign require a North Carolina driver to do?

  1. Do not enter the roadway ahead
  2. Yield to traffic already in the intersection
  3. Reduce speed and proceed with caution
  4. Come to a complete stop before proceeding Correct answer.

Explanation

The octagon shape is reserved for stop signs, and a red octagon with white letters means the driver must stop completely. After stopping, the driver yields as required and proceeds only when safe. A yield sign uses a triangle shape, not an octagon.

Question 23North Carolina traffic laws, signs, signals, and markings

On a two-lane street, a fire engine approaches from behind with its siren sounding and red lights flashing. What must a North Carolina driver do?

  1. Stop in the travel lane immediately and wait
  2. Pull as far to the right as possible and stop Correct answer.
  3. Maintain speed and wave the emergency vehicle around
  4. Speed up to reach the next intersection and turn off

Explanation

North Carolina law requires drivers to yield the right-of-way to emergency vehicles using sirens and flashing lights. The proper response is to pull to the right edge of the roadway and stop until the emergency vehicle has passed. Stopping in the lane or speeding up can block the vehicle and create a hazard.

Question 24North Carolina traffic laws, signs, signals, and markings

You are driving in the right lane of a multi-lane road and see a broken white line separating your lane from the lane to your left. What does the broken white line mean?

  1. You must stay in your lane until the line becomes solid
  2. Passing is prohibited on both sides of the line
  3. The lane to your left is reserved for oncoming traffic
  4. You may change lanes when it is safe to do so Correct answer.

Explanation

White lines separate traffic moving in the same direction, and a broken white line means lane changes are permitted when safe. A solid white line discourages lane changes but does not mark opposing traffic. Yellow lines are used to separate traffic moving in opposite directions.

Question 25North Carolina traffic laws, signs, signals, and markings

A traffic signal displays a flashing yellow light for your lane at an intersection. How should a North Carolina driver respond?

  1. Accelerate to clear the intersection before the light changes
  2. Treat the signal as a four-way stop
  3. Slow down and proceed with caution when it is safe Correct answer.
  4. Stop completely and wait for a green light

Explanation

A flashing yellow signal means caution: slow down, check for traffic and pedestrians, and proceed only when it is safe. It does not require a complete stop the way a flashing red signal does. Drivers should not speed up to beat a signal change.

Question 26North Carolina traffic laws, signs, signals, and markings

A school bus ahead of you has its yellow lights flashing, but its red lights and stop arm are not activated. What should you do?

  1. Pass the bus on the left without slowing
  2. Slow down and prepare to stop for children Correct answer.
  3. Sound your horn and continue at the posted speed
  4. Stop immediately behind the bus and wait

Explanation

Flashing yellow lights on a school bus warn that the bus is preparing to stop, so drivers should slow down and be ready to stop. The red lights and stop arm, once activated, require traffic to stop. Passing a bus with yellow lights flashing without caution is dangerous because children may be nearby.

Question 27North Carolina traffic laws, signs, signals, and markings

Under North Carolina law, when passing a bicyclist on a roadway, a motorist must leave at least how much clearance?

  1. Six feet
  2. Two feet Correct answer.
  3. One foot
  4. Four feet

Explanation

North Carolina requires motorists to pass a bicyclist with at least two feet of clearance. If the lane is too narrow to allow that clearance safely, the motorist should wait until it is safe to pass. The clearance rule protects bicyclists from being struck or forced off the road.

Question 28North Carolina traffic laws, signs, signals, and markings

You are facing a circular green traffic light and want to turn left at an intersection. What does North Carolina law require?

  1. You must wait for a green arrow before turning
  2. Yield to oncoming traffic and pedestrians in the crosswalk Correct answer.
  3. You have an absolute right-of-way over all oncoming traffic
  4. You may turn only after the light turns yellow

Explanation

A circular green light permits a left turn, but the turning driver must yield to oncoming vehicles and to pedestrians lawfully in the crosswalk. A green arrow, by contrast, gives a protected turn after yielding to pedestrians and other traffic already in the intersection. The circular green does not create an absolute right-of-way.

Question 29North Carolina traffic laws, signs, signals, and markings

Two vehicles arrive at a four-way stop at the same time. Vehicle A intends to turn left, and Vehicle B intends to go straight. Both have come to a complete stop. Who has the right-of-way?

  1. Vehicle A, because it arrived first
  2. Vehicle B, because the left-turning vehicle must yield Correct answer.
  3. Vehicle A, because left turns have priority at four-way stops
  4. Neither; both must wait for a police officer

Explanation

At a four-way stop, when two vehicles arrive at the same time, the driver on the left must yield to the driver on the right. In addition, a vehicle turning left must yield to a vehicle going straight or turning right. Therefore Vehicle B, going straight, has the right-of-way over Vehicle A's left turn.

Question 30North Carolina traffic laws, signs, signals, and markings

Overhead lane-use signals show a red X above the lane you are approaching, while adjacent lanes show green arrows. What does the red X mean in North Carolina?

  1. The lane is for high-occupancy vehicles only
  2. The lane is closed to traffic Correct answer.
  3. The lane is open but you must reduce speed
  4. The lane is reserved for turning traffic only

Explanation

A red X over a lane means that lane is closed to traffic, often because of a crash, work zone, or reversed flow. Drivers must move to a lane marked with a green arrow or otherwise open. The signal applies to the lane beneath it, not to the whole roadway.

Question 31North Carolina traffic laws, signs, signals, and markings

A North Carolina driver approaching an intersection sees a steady circular yellow light. What is the required response?

  1. Treat the light as a yield sign and continue only after sounding the horn.
  2. Accelerate to clear the intersection before the light turns red.
  3. Stop before the intersection if safe; otherwise proceed cautiously. Correct answer.
  4. Come to a complete stop and remain stopped until the light turns green.

Explanation

A steady yellow light warns that the signal is about to turn red. North Carolina law requires the driver to stop before the intersection if that can be done safely; if the vehicle is too close to stop safely, the driver should proceed through the intersection with caution. It is not a command to speed up, and it does not require a stop when stopping would be unsafe.

Question 32North Carolina traffic laws, signs, signals, and markings

A pedestrian signal shows a flashing orange hand as you reach the curb. What does it mean?

  1. The signal is broken and pedestrians should wait for a green light.
  2. Vehicles may turn right without yielding to pedestrians.
  3. Pedestrians may begin crossing and have the right-of-way.
  4. Do not start crossing; finish if already in the crosswalk. Correct answer.

Explanation

A flashing orange hand means pedestrians should not begin crossing. A pedestrian who is already in the crosswalk when the hand begins flashing should continue to the other side. The countdown, where provided, shows the remaining crossing time.

Question 33North Carolina traffic laws, signs, signals, and markings

Under North Carolina law, how must a child who is under age 8 and weighs less than 80 pounds be restrained while riding in a passenger vehicle?

  1. On an adult's lap in the rear seat.
  2. In an appropriate child passenger restraint system. Correct answer.
  3. By the vehicle's lap and shoulder seat belt only.
  4. In the front seat with the air bag turned off.

Explanation

North Carolina requires a child passenger restraint system for children under 8 years old and under 80 pounds. The restraint must be appropriate for the child's height and weight, and the rear seat is generally safer. A regular seat belt alone does not satisfy this requirement for that age and weight group.

Question 34North Carolina traffic laws, signs, signals, and markings

On a two-lane road, your lane is bounded on the left by a broken yellow line with a solid yellow line beside it. What does this marking allow you to do?

  1. Never pass, because a solid yellow line is present.
  2. Use the opposing lane as a passing lane whenever traffic is light.
  3. Pass when safe; the broken line is on your side. Correct answer.
  4. Pass only if the vehicle ahead is traveling below the posted speed.

Explanation

When a broken yellow line is on your side of the center line, you may cross it to pass when safe. The solid yellow line beside it restricts traffic on the opposite side from passing. Passing is never permitted when it cannot be done safely or when a sign or marking prohibits it.

Question 35North Carolina traffic laws, signs, signals, and markings

At a steady circular red light in North Carolina, when may a driver turn right?

  1. Only after waiting through one full green cycle.
  2. Without stopping if no vehicles are visible.
  3. Stop, yield to pedestrians and traffic, then turn unless prohibited. Correct answer.
  4. Only if a police officer directs traffic.

Explanation

North Carolina allows a right turn at a steady red light after the driver makes a complete stop and yields to pedestrians and cross traffic. The turn is permitted unless a sign prohibits it. A right turn on red is not allowed without stopping.

Question 36North Carolina traffic laws, signs, signals, and markings

On a multi-lane highway, you approach a tow truck stopped on the shoulder with amber lights flashing. What does North Carolina's Move Over law require?

  1. Stop completely until the tow truck driver waves you past.
  2. Move to the shoulder and drive around the tow truck.
  3. Maintain speed and lane because tow trucks are not covered by the Move Over law.
  4. Move over one lane if possible; otherwise slow and proceed cautiously. Correct answer.

Explanation

North Carolina's Move Over law applies when approaching a stationary emergency vehicle, tow truck, or utility vehicle with warning lights activated. The driver must move to a lane not adjacent to the stopped vehicle if that can be done safely; if not, the driver must slow down and proceed cautiously.

Question 37North Carolina traffic laws, signs, signals, and markings

A school bus on a two-lane, undivided road stops with its red lights flashing and stop arm extended. What must traffic in both directions do?

  1. Stop until the red lights stop flashing. Correct answer.
  2. Continue at posted speed if no children are visible.
  3. Slow to 25 mph and pass carefully.
  4. Stop only if traveling behind the bus.

Explanation

On a two-lane, undivided road, traffic in both directions must stop when a school bus displays flashing red lights and its stop arm. Drivers must remain stopped until the red lights stop flashing, even if no children are immediately visible. Passing the bus during this phase is unlawful.

Question 38North Carolina traffic laws, signs, signals, and markings

A solid white line along the right side of your travel lane marks what?

  1. A lane reserved for passing.
  2. The left edge of a two-way roadway.
  3. The right edge of the roadway. Correct answer.
  4. The center line of a divided highway.

Explanation

A solid white line on the right side of the lane marks the right edge of the roadway or travel lane. Yellow lines generally mark the left edge of a divided highway or separate traffic moving in opposite directions. Edge lines help drivers keep their vehicle within the intended travel path.

Question 39North Carolina traffic laws, signs, signals, and markings

A traffic signal displays a flashing red left-turn arrow. What must a North Carolina driver do before turning left?

  1. Turn only after the vehicle behind sounds its horn.
  2. Stop, yield, then turn when clear. Correct answer.
  3. Wait for a green arrow even if the intersection is clear.
  4. Proceed without stopping because the arrow is flashing.

Explanation

A flashing red left-turn arrow requires the driver to stop and yield before turning. After stopping, the driver may turn left when oncoming traffic and pedestrians are clear. A flashing yellow arrow, by contrast, does not require a stop.

Question 40North Carolina traffic laws, signs, signals, and markings

A pedestrian hybrid beacon at a mid-block crossing displays alternating flashing red lights after a solid red phase. What may a driver do?

  1. Proceed without stopping because the pedestrian phase has ended.
  2. Stop, then proceed if the crosswalk is clear. Correct answer.
  3. Stop and remain stopped until the beacon goes completely dark.
  4. Treat the signal as a flashing yellow and slow only.

Explanation

At a pedestrian hybrid beacon, alternating flashing red lights mean the driver must stop and then may proceed if the crosswalk is clear. A solid red light requires the driver to remain stopped while pedestrians cross. The beacon should not be treated as a flashing yellow.

Question 41Safe and defensive driving practices

You are coaching a learner on a two-lane road at the posted limit when a vehicle begins following very closely behind. What should you instruct the learner to do?

  1. Accelerate well above the posted limit to open up a gap behind the car.
  2. Brake firmly a few times to warn the tailgater that the gap is too small.
  3. Increase the space ahead and slow gradually so any braking stays gentle. Correct answer.
  4. Keep the same speed and switch on the hazard flashers until the other driver backs off.

Explanation

When another driver follows too closely, the driver ahead cannot control the rear gap but can control the front gap. Adding space ahead allows earlier, smoother speed changes, so braking stays gradual and the chance of a rear-end crash drops. Brake-checking or running hazard flashers while moving can startle the tailgater and removes your own margin for error.

Question 42Safe and defensive driving practices

A learner is approaching a stopped tow truck with amber warning lights active on a multi-lane highway. What does North Carolina's move over law require the learner to do?

  1. Continue at the posted speed in the current lane while watching the flashing lights.
  2. Change lanes only if a law enforcement officer signals that it is permitted.
  3. Move over a lane if possible, otherwise slow down and pass with caution. Correct answer.
  4. Stop completely in the travel lane until an officer waves the vehicle past.

Explanation

The move over law applies when emergency, tow, or utility vehicles are stopped with warning lights on. Drivers must change lanes away from the stopped vehicle when a lane is available and the move can be made safely; if they cannot move over, they must slow down and pass cautiously. Stopping in a travel lane without direction from an officer creates a new hazard.

Question 43Safe and defensive driving practices

During heavy rain a learner's vehicle begins to hydroplane at highway speed; the steering feels light and the tires stop responding. What is the best immediate action to coach?

  1. Accelerate to push the standing water away from the tires.
  2. Apply the brakes hard to scrub off speed as quickly as possible.
  3. Ease off the accelerator and hold the wheel steady until grip returns. Correct answer.
  4. Turn the wheel sharply from side to side to feel for traction.

Explanation

Hydroplaning means the tires are riding on a film of water, so steering and braking inputs have little effect. Easing off the accelerator lets speed bleed off gradually until the tires cut through the water and grip returns. Hard braking or sharp steering while the tires are unloaded can trigger a skid the moment traction comes back.

Question 44Safe and defensive driving practices

On a four-lane undivided roadway, a school bus traveling in the opposite direction stops with its red lights flashing and stop arm extended. What must the learner driver do?

  1. Continue on, because the bus is on the opposite side of the road.
  2. Slow to 25 mph and continue past the bus with care.
  3. Stop only if children are visible near the edge of the roadway.
  4. Stop and remain stopped until the red lights stop flashing. Correct answer.

Explanation

On an undivided roadway, traffic in both directions must stop for a school bus showing flashing red lights and an extended stop arm, whether the bus is ahead of you or approaching from the opposite direction. The stop continues until the red lights stop flashing. Only on a divided highway with a median or physical barrier separating the directions does opposing traffic proceed without stopping.

Question 45Safe and defensive driving practices

At night on an unlit rural road, a learner drives at the posted 55 mph using low beams that light roughly 160 feet ahead. Why is this unsafe, and what should change?

  1. Low beams are not legal on rural roads after dark, so high beams must be used at all times.
  2. The lit distance is shorter than the distance needed to stop from that speed. Correct answer.
  3. Posted speed limits apply only during daylight hours, so the learner may choose any safe speed.
  4. High beams must be used whenever no other vehicle is present, regardless of speed.

Explanation

This is overdriving the headlights: the illuminated distance is shorter than the total stopping distance at 55 mph, which includes perception, reaction, and braking. Low beams typically reach only about 160 feet, while stopping from 55 mph takes well over 200 feet. The correction is to reduce speed so the vehicle can stop within the distance the headlights actually show.

Question 46Safe and defensive driving practices

A learner's car begins to skid on a wet curve, and the rear of the vehicle is sliding toward the left. What should the driver do?

  1. Hold the wheel straight and accelerate through the skid.
  2. Steer left, ease off the accelerator, and avoid hard braking. Correct answer.
  3. Pull the parking brake to slow the rear wheels down.
  4. Steer right and brake firmly to straighten the vehicle out.

Explanation

In a rear-wheel skid, the driver steers in the direction the rear is sliding, here to the left, so the front of the car follows the direction of travel and the vehicle straightens. Easing off the accelerator and avoiding hard braking lets the tires regain grip gradually. Abrupt inputs while the tires are already at their limit usually make the skid worse.

Question 47Safe and defensive driving practices

You are teaching a learner to enter a modern roundabout for the first time. What is the correct entry procedure?

  1. Yield to vehicles already in the roundabout and enter to the right. Correct answer.
  2. Come to a complete stop at the yield line every time before entering.
  3. Signal left and merge into the circle without yielding to circulating traffic.
  4. Enter with the left turn signal on, then change lanes inside the circle.

Explanation

A modern roundabout is built for continuous movement: entering drivers yield to vehicles already circulating, then enter to the right and travel counterclockwise. A full stop at the yield line is required only when traffic makes it necessary. Once inside, drivers keep their lane and signal for the exit after passing the exit before theirs.

Question 48Safe and defensive driving practices

A learner is approaching an active interstate work zone where the limit has been lowered and lanes are shifted. What should you coach the learner to do?

  1. Keep the original highway speed until reaching the workers' position.
  2. Slow before the lane shift and add extra following distance. Correct answer.
  3. Move in close behind the vehicle ahead to discourage lane changes.
  4. Turn on high beams and hold speed steadily through the zone.

Explanation

Work zones combine a reduced speed limit, narrowed or shifted lanes, and frequent sudden slowing, so the safest approach is to slow before the taper and leave extra following distance. Early, gentle braking also gives drivers behind more time to react. Penalties for speeding in work zones are higher, which reinforces exact compliance with the posted limit.

Question 49Safe and defensive driving practices

A learner is driving alongside the right rear of a tractor-trailer when the truck's right turn signal comes on. What is the safest response, and why?

  1. Drop back out of the right-side blind spot and let the truck complete the turn. Correct answer.
  2. Sound the horn and hold position alongside the trailer to stay visible.
  3. Accelerate to pass before the turn starts, since the smaller vehicle can move faster.
  4. Move forward and to the right of the truck to stay clear of its path.

Explanation

Large trucks have deep blind spots, often called the No-Zone, along the right side and directly behind the trailer. A truck preparing a right turn commonly swings wide to the left first, so a car alongside the right rear can be squeezed or struck. Dropping back keeps the learner where the truck driver can see the car and out of the trailer's sweeping path.

Question 50Safe and defensive driving practices

A learner enters a stretch of dense fog on a rural highway and switches on the high beams, which makes visibility worse. What should you coach?

  1. Follow the taillights of the vehicle ahead as closely as possible.
  2. Switch to low beams and reduce speed to match the visible distance. Correct answer.
  3. Keep the high beams on, because they light more of the roadway ahead.
  4. Turn on the hazard flashers and maintain the current speed.

Explanation

Fog droplets reflect light straight back at the driver, so high beams create a bright wall of glare while low beams aim lower and keep more of the road surface visible. Speed should drop so the vehicle can stop within the distance actually visible. Following taillights closely is risky because the lead driver may brake suddenly or leave the roadway.
