Question 1Road rules and safe driving

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

  1. Slow down and proceed if the road appears clear
  2. Stop only if pedestrians are present
  3. Yield to traffic on the right and then continue
  4. Stop before the intersection and remain stopped until the light turns green Correct answer.

Explanation

A steady red signal means a full stop must be made before the stop line, crosswalk, or intersection, and the vehicle must stay stopped until a green signal or a lawful turn on red is completed. Proceeding without stopping violates the signal and creates collision risk with cross traffic.

Question 2Road rules and safe driving

When are you permitted to turn right at a red light?

  1. Never, because right turns on red are always illegal
  2. Whenever no police officer is watching the intersection
  3. Only when the light has been red for at least thirty seconds
  4. After stopping, when no sign prohibits it and you yield to traffic and pedestrians Correct answer.

Explanation

A right turn on red is allowed after a complete stop unless a sign forbids it, and the driver must yield the right of way to pedestrians and to vehicles already in or approaching the intersection. The maneuver is a privilege conditioned on the stop and on yielding, not an automatic right.

Question 3Road rules and safe driving

What is the correct action when an emergency vehicle approaches with sirens and flashing lights?

  1. Speed up to reach the next intersection before it arrives
  2. Pull over to the right edge and stop until it passes Correct answer.
  3. Stop immediately in your lane wherever you are
  4. Maintain your speed and lane so the driver can predict your path

Explanation

Drivers must yield to emergency vehicles using lights and sirens by pulling as far as possible to the right edge of the roadway and stopping until the vehicle passes. Stopping abruptly in a travel lane can block the emergency vehicle and cause a rear-end crash.

Question 4Road rules and safe driving

At an intersection with no signs or signals, which vehicle generally has the right of way?

  1. The vehicle that arrives first Correct answer.
  2. The vehicle that arrives second
  3. The vehicle on the left
  4. The vehicle traveling faster

Explanation

At an uncontrolled intersection, the first vehicle to arrive has the right of way, and if two arrive at the same time the driver on the left must yield to the driver on the right. This first-arrival rule keeps movements predictable when no device assigns priority.

Question 5Road rules and safe driving

How far before a turn should you normally signal?

  1. Only as you begin the turn
  2. After completing the turn
  3. At least 100 feet before the turn Correct answer.
  4. About 10 feet before the turn

Explanation

Signals should be given at least 100 feet before a turn so other drivers and pedestrians have time to react. Signaling only at the moment of turning gives others almost no warning and is a common cause of collisions.

Question 6Road rules and safe driving

What is the meaning of a solid white line between lanes of traffic moving in the same direction?

  1. Lane changes are discouraged and should be avoided Correct answer.
  2. It marks the left edge of the roadway
  3. Passing is encouraged to keep traffic moving
  4. You may cross it freely at any time

Explanation

A solid white line separates lanes traveling in the same direction and indicates that lane changes are discouraged, though they may be made with care where legal. It is not an absolute barrier like a double yellow line, but drivers should avoid crossing it casually.

Question 7Road rules and safe driving

What must a driver do at a stop sign?

  1. Slow to a crawl and continue if the way is clear
  2. Stop only if a stop line is painted on the road
  3. Stop only when another vehicle is visible
  4. Come to a complete stop and yield to traffic and pedestrians Correct answer.

Explanation

A stop sign requires a complete stop at the stop line, crosswalk, or edge of the intersection, followed by yielding to vehicles and pedestrians before proceeding. A rolling stop does not satisfy the legal requirement.

Question 8Road rules and safe driving

What is the purpose of a safety belt's shoulder strap?

  1. To allow the driver to reach the controls more easily
  2. To replace the need for a headrest
  3. To keep the driver sitting upright during long trips
  4. To restrain the upper body and prevent it from striking the interior or other occupants Correct answer.

Explanation

The shoulder strap restrains the upper torso so that in a crash the body does not pitch forward into the dashboard, windshield, or other occupants. Combined with the lap belt, it spreads crash forces across strong parts of the body.

Question 9Road rules and safe driving

You are driving in heavy rain and the steering suddenly feels light while the vehicle drifts. What is happening and what should you do?

  1. The power steering has failed; turn the wheel sharply to recover
  2. The road is icy; accelerate to regain grip
  3. The tires are hydroplaning; ease off the accelerator and avoid hard braking Correct answer.
  4. The brakes have failed; pump them firmly and continue at speed

Explanation

Light steering and drifting in wet conditions indicate hydroplaning, where water lifts the tires off the pavement. The correct response is to ease off the accelerator, keep the wheel steady, and avoid sudden braking or steering so the tires can regain contact with the road.

Question 10Road rules and safe driving

You are approaching a school bus stopped on your side of the road with its red lights flashing. What must you do?

  1. Pass on the left after yielding to oncoming traffic
  2. Honk to warn children and continue
  3. Slow down and pass carefully if children are not visible
  4. Stop and wait until the red lights stop flashing Correct answer.

Explanation

When a school bus displays flashing red lights on an undivided road, traffic in both directions must stop and remain stopped until the lights are turned off. The rule protects children who may be crossing the roadway out of the driver's view.

Question 11Road rules and safe driving

You are entering a freeway from an acceleration lane. What is the safest procedure?

  1. Use the lane to build speed matching traffic, then merge into a suitable gap Correct answer.
  2. Stop at the end of the ramp and wait for a large gap
  3. Enter at a slow speed and let freeway traffic adjust
  4. Merge immediately and then accelerate to match traffic

Explanation

The acceleration lane exists so drivers can build speed to match freeway traffic and merge smoothly into a safe gap. Merging far below traffic speed forces other drivers to brake and creates a serious hazard.

Question 12Road rules and safe driving

What is the recommended following distance under normal dry conditions?

  1. One car length for every ten miles per hour
  2. Exactly two car lengths at any speed
  3. At least three seconds behind the vehicle ahead Correct answer.
  4. Half a second at highway speeds

Explanation

A minimum three-second gap gives a driver time to perceive a hazard and stop, and the gap should be increased in rain, darkness, or when following large vehicles. The seconds method adjusts automatically as speed rises, unlike fixed car lengths.

Question 13Road rules and safe driving

You are driving at night and an oncoming vehicle's high beams glare into your eyes. What should you do?

  1. Flash your own high beams to warn the other driver
  2. Look directly at the headlights to judge the distance
  3. Close your eyes briefly until the vehicle passes
  4. Look toward the right edge of your lane and slow down Correct answer.

Explanation

When glare from oncoming high beams affects your vision, look toward the right edge of your lane to keep the vehicle positioned and reduce the blinding effect, and slow down until you can see clearly again. Looking into the lights temporarily destroys night vision.

Question 14Road rules and safe driving

What does a flashing yellow traffic light mean?

  1. Proceed with caution after yielding to cross traffic Correct answer.
  2. Prepare to stop because the light will turn red immediately
  3. Come to a complete stop before proceeding
  4. The signal is broken and normal right-of-way rules do not apply

Explanation

A flashing yellow signal directs drivers to slow down and proceed with caution, yielding to vehicles and pedestrians already lawfully in the intersection. It does not require a stop, but it warns that conflicts may exist.

Question 15Road rules and safe driving

On a two-lane road, where should you begin a left turn from?

  1. From the shoulder to the right of the travel lane
  2. From the left lane or center turn lane nearest the center line Correct answer.
  3. From whichever lane has the shortest line of traffic
  4. From the right lane so you have more room to swing wide

Explanation

A left turn should be started from the lane closest to the center line, or from a designated center turn lane, so the turn does not cut across other lanes of traffic. Swinging wide from the right lane can strike vehicles or pedestrians beside you.

Question 16Road rules and safe driving

You are on a road with a broken yellow center line on your side. What does this permit?

  1. Exceeding the posted speed limit while passing
  2. Parking on the left side of the roadway
  3. Passing when the way ahead is clear and it is safe Correct answer.
  4. Driving on the left side for as long as you wish

Explanation

A broken yellow line on your side of the center line means you may cross it to pass when the road ahead is clear and the maneuver can be completed safely. The marking permits passing but does not remove the duty to ensure it is safe.

Question 17Road rules and safe driving

You are driving and begin to feel drowsy. What is the safest course of action?

  1. Open a window and continue to your destination
  2. Turn up the radio and drive faster to stay alert
  3. Drink coffee while driving and keep going
  4. Pull over in a safe place and rest before continuing Correct answer.

Explanation

Drowsiness impairs reaction time and judgment much like alcohol, and short-term tricks such as fresh air or caffeine do not restore alertness reliably. The safe response is to stop in a safe location and rest, or end the trip, rather than push on.

Question 18Road rules and safe driving

Which statement about sharing the road with motorcyclists is correct?

  1. Two motorcycles may never share a lane under any circumstance
  2. Motorcyclists are entitled to the full width of a lane Correct answer.
  3. A motorcycle may be passed within the same lane if there is room
  4. Motorcyclists must always ride in the left portion of a lane

Explanation

A motorcycle is entitled to a full lane, and other drivers must not share the lane with it or squeeze past within the lane. Motorcyclists may need the lane width to avoid hazards such as potholes, gravel, or wind gusts.

Question 19Road rules and safe driving

You are driving behind a large truck that is about to make a right turn. What hazard should you anticipate?

  1. The truck may swing wide to the left before turning and its rear wheels will track inside the front path Correct answer.
  2. The truck will turn without signaling
  3. The truck will stop in the intersection for a long time
  4. The truck's brake lights will not function

Explanation

Large vehicles often swing left before a right turn to clear the curb, and their rear wheels cut inside the path of the front wheels, so a vehicle that pulls alongside on the right can be crushed. Stay back and never pass a turning truck on the right.

Question 20Road rules and safe driving

You are stopped behind a vehicle at a railroad crossing when the gates begin to lower. What should you do?

  1. Stop on the tracks only if the vehicle ahead blocks you
  2. Drive around the gate before the train arrives
  3. Back up quickly to clear the crossing
  4. Stay stopped behind the vehicle and wait for the gates to rise Correct answer.

Explanation

When warning devices activate, drivers must stop and remain clear of the tracks until the train has passed and the gates rise. Never drive around a lowered gate or stop on the tracks, because trains cannot stop quickly and the gate is a warning of an approaching train.

Question 21Road rules and safe driving

You are driving on a highway and your vehicle begins to skid on a wet road. What is the best initial response?

  1. Steer sharply in the opposite direction of the skid
  2. Brake as hard as possible and hold the wheel straight
  3. Accelerate to pull the vehicle out of the skid
  4. Ease off the accelerator and steer gently in the direction you want to go Correct answer.

Explanation

In a skid, the driver should ease off the accelerator and make smooth steering corrections toward the intended path, avoiding hard braking that can shift weight and worsen the loss of traction. Sudden inputs reduce what little grip the tires have.

Question 22Road rules and safe driving

What is the legal blood alcohol concentration limit for drivers 21 and older in most U.S. states?

  1. 0.02 percent
  2. 0.10 percent
  3. 0.05 percent
  4. 0.08 percent Correct answer.

Explanation

The national standard for adult drivers is a blood alcohol concentration below 0.08 percent, and drivers under 21 are held to zero-tolerance limits. Alcohol impairs judgment, coordination, and reaction time well before a driver feels intoxicated.

Question 23Road rules and safe driving

You are driving on a multi-lane road and a vehicle is tailgating you closely. What is the safest response?

  1. Speed up well beyond the limit to create distance
  2. Wave the driver around and slow down gradually
  3. Change lanes when it is safe and let the vehicle pass Correct answer.
  4. Brake sharply to warn the driver to back off

Explanation

When tailgated, the safest response is to move out of the way at the first safe opportunity, such as changing lanes or allowing the vehicle to pass, while maintaining a steady speed. Brake-checking or racing away escalates the risk for everyone nearby.

Question 24Road rules and safe driving

You are approaching a blind curve on a narrow two-lane road and want to pass a slow-moving vehicle. What is the correct judgment?

  1. Do not pass, because you cannot see oncoming traffic through the curve Correct answer.
  2. Pass if you can complete the maneuver before the curve begins
  3. Pass only if the vehicle ahead signals you to do so
  4. Pass if the center line is broken, because the marking guarantees safety

Explanation

Passing requires seeing far enough ahead to confirm the oncoming lane is clear for the whole maneuver, and a blind curve removes that sight distance. A broken line permits passing only when it is safe; it does not guarantee that it is.

Question 25Road rules and safe driving

You are the first vehicle to arrive at the scene of a crash with injuries on a highway. What should you do first?

  1. Stop safely off the roadway, warn other traffic, and call for emergency help Correct answer.
  2. Park in the travel lane to block traffic and stand beside your vehicle
  3. Take photographs of the scene before doing anything else
  4. Move the injured people out of the vehicles immediately

Explanation

The first priorities are to avoid becoming part of the crash, warn approaching traffic, and summon emergency medical help. Moving injured people without training can worsen spinal or internal injuries, so it should wait for responders unless there is immediate danger such as fire.

Question 26Road rules and safe driving

What does a red octagonal sign require a driver to do?

  1. Slow down and proceed only if other traffic is present
  2. Stop only when a pedestrian is visible
  3. Yield to traffic on the right but keep rolling
  4. Come to a complete stop before the crosswalk or intersection Correct answer.

Explanation

A red octagon is the universal stop sign. The driver must bring the vehicle to a full halt at the marked stop line, crosswalk, or edge of the intersection, then proceed only when it is safe. Rolling slowly through the sign does not satisfy the legal requirement.

Question 27Road rules and safe driving

A traffic light shows a steady red arrow pointing left. What may a driver do?

  1. Complete a left turn only if already inside the intersection
  2. Wait until the arrow changes before turning left Correct answer.
  3. Treat the arrow as a caution and turn slowly
  4. Turn left after yielding to oncoming traffic

Explanation

A steady red arrow means turning in the direction of the arrow is prohibited at that moment. The driver must remain stopped until a green arrow or green light appears. It is not the same as a steady red circle, where a right turn on red may sometimes be allowed.

Question 28Road rules and safe driving

Which behavior is required when an emergency vehicle with sirens and flashing lights approaches from behind?

  1. Stop immediately wherever the vehicle is
  2. Speed up to reach the next exit before it passes
  3. Pull to the right edge and stop until it passes Correct answer.
  4. Continue at the same speed in the left lane

Explanation

Drivers must yield the right of way to emergency vehicles using lights and sirens. The usual procedure is to pull as far as possible toward the right edge of the roadway and stop until the vehicle has passed. Blocking the path or stopping abruptly in a travel lane creates new hazards.

Question 29Road rules and safe driving

What is the purpose of a center left-turn lane marked on a busy road?

  1. To allow faster vehicles to overtake slower ones
  2. To provide a lane for buses only
  3. To serve as a shoulder for disabled vehicles
  4. To store vehicles waiting to turn left from either direction Correct answer.

Explanation

A center left-turn lane, sometimes called a two-way left-turn lane, is shared by traffic from both directions for preparing and completing left turns. Drivers enter it only shortly before turning and may not use it for passing or through travel. Using it as a travel lane is both illegal and hazardous.

Question 30Road rules and safe driving

When parking on a hill facing downhill next to a curb, which way should the front wheels be turned?

  1. Away from the curb, into the traffic lane
  2. It makes no difference if the parking brake is set
  3. Toward the curb, so the tires rest against it Correct answer.
  4. Straight ahead, with the parking brake set

Explanation

Facing downhill with a curb, the front wheels should be turned toward the curb. If the vehicle rolls, the tires will press against the curb and help stop it. Leaving wheels straight or turned into traffic risks the vehicle rolling into the roadway.

Question 31Road rules and safe driving

What does a yellow diamond-shaped sign generally indicate?

  1. A regulatory requirement such as a speed limit
  2. A construction zone with workers present
  3. A service such as fuel or lodging
  4. A warning of a road condition or hazard ahead Correct answer.

Explanation

Yellow diamond signs are warning signs that alert drivers to conditions ahead, such as curves, intersections, or pedestrian crossings. Regulatory signs are usually white rectangles or red circles, and services are shown on blue signs. Recognizing the shape and color helps drivers anticipate what is coming.

Question 32Road rules and safe driving

How should a driver signal a lane change?

  1. Rely on other drivers to notice the vehicle moving
  2. Flash the headlights once and change lanes
  3. Activate the turn signal well before moving and check mirrors and blind spot Correct answer.
  4. Signal only after the lane change is complete

Explanation

A lane change should be signaled early enough to give other drivers time to react. The driver should check mirrors and turn the head to verify the blind spot before moving over. Signaling after the move or not at all deprives others of warning.

Question 33Road rules and safe driving

What is the correct action when a pedestrian is crossing at a marked crosswalk without a signal?

  1. Sound the horn to hurry the pedestrian along
  2. Drive around behind the pedestrian without stopping
  3. Stop and yield until the pedestrian has crossed safely Correct answer.
  4. Proceed if there is enough room to pass in front

Explanation

Drivers must yield to pedestrians in marked crosswalks, whether or not a signal is present. The vehicle should stop and remain stopped until the pedestrian clears the driver's path. Honking or squeezing past intimidates pedestrians and violates their right of way.

Question 34Road rules and safe driving

You are driving in the left lane of a multi-lane highway and faster traffic is approaching from behind. What is the safest action?

  1. Brake sharply to encourage the other driver to slow
  2. Move to the right lane when it is safe to do so Correct answer.
  3. Maintain speed and stay in the left lane
  4. Speed up to match the approaching traffic

Explanation

The left lane is intended for passing, and slower traffic should keep right. When a faster vehicle approaches, the driver should complete any pass in progress and move right when it is safe. Holding the left lane forces others to pass on the right, which increases risk.

Question 35Road rules and safe driving

A school zone sign shows a flashing yellow light during posted hours. What does this mean?

  1. Buses are the only vehicles permitted
  2. The school zone speed limit is in effect Correct answer.
  3. Drivers must stop before the school entrance
  4. The school is closed and normal limits apply

Explanation

Flashing yellow lights at a school zone indicate that children are likely to be present and the reduced speed limit applies. Drivers must slow to the posted school zone speed and watch for children. The flashing signal does not require a stop unless a stop sign or crossing guard directs one.

Question 36Road rules and safe driving

You are driving on an icy bridge and need to slow down. What is the safest technique?

  1. Release the accelerator and brake gently in a straight line Correct answer.
  2. Apply the brakes firmly and steer toward the shoulder
  3. Pump the accelerator to maintain engine speed
  4. Downshift abruptly and turn the wheel to test traction

Explanation

Bridges freeze before other road surfaces because cold air circulates beneath them. On ice, abrupt braking or steering can cause a loss of traction, so the driver should ease off the accelerator and brake gently while traveling straight. Smooth inputs give the tires the best chance to maintain grip.

Question 37Road rules and safe driving

What is the proper way to merge onto a road from a driveway blocked by a hedge?

  1. Accelerate quickly so any approaching vehicle sees the car
  2. Stop, then edge forward slowly until the view is clear before entering Correct answer.
  3. Rely on sounds from passing vehicles to judge traffic
  4. Creep forward until the front bumper enters the roadway, then look

Explanation

A hedge limits the view of approaching traffic, so the driver must stop and then inch forward until the sight line opens. Only after confirming the way is clear should the vehicle enter the road. Sound alone is unreliable, and darting out gives others no time to react.

Question 38Road rules and safe driving

When may a driver legally pass another vehicle on the right?

  1. Whenever the vehicle ahead is traveling below the speed limit
  2. When the vehicle ahead is turning left and there is room to pass on the right Correct answer.
  3. Never, under any circumstances
  4. Only on a two-lane road with a broken center line

Explanation

Passing on the right is generally allowed when the vehicle ahead is making or preparing for a left turn and there is sufficient paved space. It may also be allowed on multi-lane roads where lanes move in the same direction. Passing on the shoulder or off the pavement is not permitted.

Question 39Road rules and safe driving

You are driving and a front tire suddenly blows out. What should you do first?

  1. Turn the wheel sharply to test the steering
  2. Shift into neutral and coast to a stop
  3. Brake hard and pull immediately to the shoulder
  4. Hold the wheel firmly and ease off the accelerator Correct answer.

Explanation

A blowout can pull the vehicle toward the failed tire, so the driver should grip the wheel firmly and keep it straight. Easing off the accelerator lets the vehicle slow gradually before any braking. Hard braking or sharp steering during a blowout can cause a loss of control.

Question 40Road rules and safe driving

What is the main reason to increase following distance behind a motorcycle?

  1. Motorcycles are required to travel below the speed limit
  2. Motorcyclists may need to swerve suddenly for road hazards Correct answer.
  3. Motorcycles accelerate more slowly than cars
  4. Motorcycle brake lights are always dim

Explanation

Motorcyclists are exposed to hazards such as potholes, gravel, and wet patches that a car would barely notice. They may brake or swerve suddenly to avoid these conditions, so a larger following gap gives the driver time to react. Tailgating a motorcycle leaves almost no margin for error.

Question 41Road rules and safe driving

A traffic officer directs you to proceed through an intersection while the light is red. What should you do?

  1. Wait for the light to turn green
  2. Obey the officer's direction Correct answer.
  3. Proceed only after other drivers move
  4. Sound the horn and remain stopped

Explanation

Directions from a police officer or authorized traffic controller override signals, signs, and pavement markings. When an officer waves traffic through a red light, the driver should follow that instruction carefully. Ignoring the officer can disrupt traffic control and create confusion.

Question 42Road rules and safe driving

You are on a one-way street and want to turn left onto another one-way street. Where should the turn begin?

  1. From any lane with enough room
  2. From the far right lane
  3. From the center lane only
  4. From the left lane nearest the turn Correct answer.

Explanation

On a one-way street, a left turn into another one-way street should be made from the left lane. Because all traffic moves the same direction, the left lane is closest to the new road and minimizes crossing paths. Turning from a right or center lane would cut across other vehicles.

Question 43Road rules and safe driving

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

  1. Keep high beams on to see farther ahead
  2. Use high beams only when the road curves
  3. Alternate high and low beams to signal a pass
  4. Switch to low beams to avoid blinding the driver ahead Correct answer.

Explanation

High beams aimed at the back of a leading vehicle reflect into the mirrors and can blind its driver. Drivers should dim to low beams when following within a reasonable distance as well as when meeting oncoming traffic. Courtesy and visibility both favor low beams in these situations.

Question 44Road rules and safe driving

What is the effect of drinking alcohol on a driver's ability to judge speed and distance?

  1. Judgment is impaired even at low blood alcohol levels Correct answer.
  2. Judgment is affected only above the legal limit
  3. Judgment is unaffected if the driver feels alert
  4. Judgment improves slightly because the driver relaxes

Explanation

Alcohol impairs coordination, reaction time, and the ability to judge speed and distance, and these effects begin at low levels. A driver may feel alert while still being impaired. This is why any alcohol before driving is a risk, not just amounts above the legal limit.

Question 45Road rules and safe driving

When approaching a railroad crossing with no gates and no flashing lights, what should a driver do?

  1. Stop for exactly three seconds then accelerate
  2. Slow down, look and listen, and cross only when clear Correct answer.
  3. Maintain speed because the crossing is unprotected
  4. Follow the vehicle ahead closely across the tracks

Explanation

At a passive crossing with no gates or lights, the driver is responsible for checking for trains. The vehicle should slow, look both ways, and listen with windows down before crossing. Following closely behind another vehicle can leave the car stranded on the tracks.

Question 46Road rules and safe driving

You are driving on a road with a solid yellow center line on your side. What does it mean?

  1. The line marks the edge of the roadway
  2. Passing is permitted when the road ahead is clear
  3. You may cross it to make a left turn into a driveway
  4. Passing is prohibited on your side of the road Correct answer.

Explanation

A solid yellow line on the driver's side of the center line means passing is prohibited in that direction. The restriction exists because sight distance or road conditions make passing unsafe. A driver may still cross the line to turn into a driveway or side road where permitted.

Question 47Road rules and safe driving

A vehicle ahead of you has its left turn signal on but has not moved for several seconds. What is the best response?

  1. Sound the horn repeatedly to prompt the turn
  2. Wait behind the vehicle until it completes the turn or you can pass safely on the right Correct answer.
  3. Drive onto the shoulder to go around
  4. Pass on the left as soon as the oncoming lane looks empty

Explanation

A signaled left turn may be delayed by oncoming traffic, and the lead driver may still move unexpectedly. Patience is safer than guessing the driver's intent. Passing on the right is only lawful when there is paved space and the situation clearly permits it.

Question 48Road rules and safe driving

You are driving at highway speed and the accelerator pedal sticks. What is the best sequence of actions?

  1. Shift to neutral, brake firmly, and steer to a safe place to stop Correct answer.
  2. Pump the brake pedal repeatedly and continue driving
  3. Open the door and look at the pedal while steering
  4. Turn off the ignition immediately while at speed

Explanation

If the accelerator sticks, the driver should shift to neutral to cut engine power to the wheels, then brake firmly and steer to a safe stopping place. Turning off the ignition at speed can lock the steering and disable power assist. Keeping control of the vehicle while slowing is the priority.

Question 49Road rules and safe driving

On a divided highway, you see a vehicle approaching in your lane from the wrong direction. What should you do?

  1. Move to the right shoulder and stop, then warn others if safe Correct answer.
  2. Continue in your lane and flash your headlights
  3. Stop in the center of your lane and wait
  4. Accelerate to pass the vehicle quickly

Explanation

A wrong-way vehicle is an extreme hazard, and the safest immediate step is to move as far right as possible and stop clear of the travel lane. Flashing lights may help alert the other driver but should not replace evasive action. Stopping in the center of the lane leaves the vehicle directly in the path of danger.

Question 50Road rules and safe driving

Why is it unsafe to rely only on a vehicle's rearview mirrors when changing lanes?

  1. Mirrors show a reversed image of the road
  2. Mirrors leave blind spots that a head check reveals Correct answer.
  3. Mirrors distort distance at low speeds only
  4. Mirrors are not adjustable on most vehicles

Explanation

Mirrors cannot show every area beside and behind the vehicle, so blind spots remain even when they are properly adjusted. A brief head check over the shoulder confirms that no vehicle is hidden there. Relying on mirrors alone is a frequent cause of sideswipe collisions.
