1. While driving, about how far ahead should you be scanning the road so you have time to spot a problem and react?

At least 10 seconds ahead
At least 3 seconds ahead
About one car length for every 10 mph of speed
At least 30 seconds ahead

Answer: A — At least 10 seconds ahead

Scanning at least 10 seconds ahead gives a driver time to react and avoid last-minute moves.

2. On a dry road, what rule should you use to judge a safe following distance behind the car ahead?

One car length for every 10 mph of speed
The three-second rule
The two-second rule
The ten-second rule

Answer: B — The three-second rule

The three-second rule is the recommended way to judge following distance.

3. A car merges into your lane and ends up very close in front of you. What should you do to restore a safe following distance?

Move into another lane immediately
Ease off the accelerator to reopen the gap
Tap the brakes rapidly to signal the driver ahead
Flash your headlights at the car ahead

Answer: B — Ease off the accelerator to reopen the gap

Easing off the accelerator rebuilds the space without a sudden, risky maneuver.

4. In your rearview mirror you see a driver following far too closely behind you. What should you do?

Tap your brakes to warn them off
Speed up so they fall further behind
Hold your course and speed, then move right when safe to let them pass
Move into the left lane so they can't tailgate as easily

Answer: C — Hold your course and speed, then move right when safe to let them pass

Holding your speed and course, then moving right when it's safe, lets the tailgater pass without provoking a reaction.

5. You're approaching an intersection where cross traffic faces a red light, so you have the right-of-way. What should you still do before proceeding?

Sound your horn to alert cross traffic
Look both ways before proceeding
Speed up slightly to clear the intersection faster
Proceed at normal speed without checking, since you have the right-of-way

Answer: B — Look both ways before proceeding

You should look both ways even when cross traffic faces a red light or stop sign, since the right-of-way doesn't guarantee another driver will stop.

6. Before changing lanes, a driver checks for vehicles in the blind spot by looking over their shoulder. What should they move to do this correctly?

Only the head, turning it to look through the side window
Just the eyes, glancing sideways without turning the head
The head and shoulders together, twisting the torso
The steering wheel slightly toward the lane, along with the head

Answer: A — Only the head, turning it to look through the side window

A blind-spot check is done by turning only the head to look through the side window, never the body or the wheel.

7. You're driving at night on a dark, open country road where high beams are legal. What should you make sure of before relying on them?

That the high beams are switched on only in town
That the car can be stopped within the distance the high beams light up
That the high beams stay on so oncoming drivers can see you
That the low beams are used instead for better range

Answer: B — That the car can be stopped within the distance the high beams light up

High beams should only be relied on if the car can stop within the distance they illuminate.

8. An oncoming car's headlights are too bright and glaring into your eyes at night. What should you do?

Look at the center line to keep your position in the lane
Look toward the right edge of your lane and watch the other vehicle from the corner of your eye
Switch on your own high beams so the other driver dims theirs
Look directly at the oncoming headlights so your eyes adjust faster

Answer: B — Look toward the right edge of your lane and watch the other vehicle from the corner of your eye

Looking toward the right edge of the lane avoids the glare while still tracking the oncoming vehicle peripherally; retaliating with high beams is not recommended.

9. At night you notice a vehicle approaching with only one headlight working. What should you do?

Keep as far right as possible, since it could be a motorcycle, bicycle, or a car with a headlight out
Flash your high beams to warn the driver their headlight is out
Assume it's a motorcycle and pass it immediately
Move toward the center line to give it a wide berth on your left

Answer: A — Keep as far right as possible, since it could be a motorcycle, bicycle, or a car with a headlight out

A single approaching light could be a narrower vehicle like a motorcycle or bicycle, so staying far right gives extra clearance.

10. Driving toward the sun makes it hard to see the road ahead. What is a recommended way to reduce this glare problem?

Wear tinted glasses with a dark tint at night as well
Wear polarized sunglasses and keep the windshield clean
Keep less space ahead so you can react to the car in front sooner
Keep the visor down at all times, even in shade

Answer: B — Wear polarized sunglasses and keep the windshield clean

Polarized sunglasses and a clean windshield are both recommended ways to cut sun glare.

11. Before heading down a steep, icy downhill grade, what should you do to help prevent a skid?

Increase following distance but keep the same gear
Shift to a low gear before starting down the hill
Shift to neutral and coast down slowly
Apply the parking brake partway down

Answer: B — Shift to a low gear before starting down the hill

Shifting to low gear before a steep downhill helps prevent a skid.

12. Your car begins to skid on an icy road. What is the recommended response?

Ease off the accelerator, do not brake, and steer in the direction of the skid
Brake firmly and steer opposite the direction of the skid
Pump the brakes rapidly while turning away from the skid
Accelerate slightly and steer straight ahead

Answer: A — Ease off the accelerator, do not brake, and steer in the direction of the skid

For a slippery-surface skid, ease off the accelerator, do not brake, and steer in the direction of the skid.

13. A car with four-wheel ABS goes into a skid after hard braking. How should the driver use the brake pedal?

Take the foot off the brake completely and steer
Press the brake firmly
Ease off just enough to let the wheels roll, then reapply
Pump the brake rapidly in short bursts

Answer: B — Press the brake firmly

With four-wheel ABS, the brake should be pressed firmly.

14. A light truck with rear-wheel ABS goes into a skid after hard braking. What should the driver do?

Pump the brake pedal quickly and repeatedly
Press the brake pedal firmly and hold it down the whole time
Ease up on the brake just enough for the front wheels to roll so they can steer, then stop braking and steer into the skid
Take the foot completely off the brake immediately

Answer: C — Ease up on the brake just enough for the front wheels to roll so they can steer, then stop braking and steer into the skid

Rear-wheel ABS, common on light trucks, still allows the front wheels to lock, so the driver eases up just enough to steer, then releases the brake and steers into the skid.

15. A car without ABS goes into a skid after hard braking, and the brake pedal sinks all the way to the floor. What should the driver do?

Pump the brake pedal gently
Pull the emergency brake immediately and hold it
Take the foot off the brake and coast to a stop
Press the brake firmly and hold it down

Answer: A — Pump the brake pedal gently

If the pedal sinks to the floor while pumping the brakes, the driver should switch to pumping gently.

16. You're driving on a road covered in ice. How much should you cut your speed?

To no more than 5 mph
By 5 to 10 mph
To no more than 15 mph
By half

Answer: A — To no more than 5 mph

On ice, speed should be cut to no more than 5 mph.

17. On a cold day with wet roads, which part of the road is likely to become icy first?

Open straightaways in direct sun
Wide intersections
Bridges and overpasses
Roads recently sanded or salted

Answer: C — Bridges and overpasses

Bridges and overpasses freeze before the rest of the road.

18. A light rain begins after several weeks without rain. Why is the road especially slippery right now?

Oil and dust built up on the pavement during the dry spell haven't been washed away yet
The road is slippery only once a heavy downpour starts, not during light rain
The tires haven't had time to build up water channels
Fresh rain increases tire traction until the road fully dries

Answer: A — Oil and dust built up on the pavement during the dry spell haven't been washed away yet

Pavement is especially slippery when rain begins, particularly after a long dry spell when oil and dust haven't washed away.

19. In a heavy rainstorm you can only see about 100 feet ahead. What is the fastest it's safe to drive?

45 mph
30 mph
50 mph
15 mph

Answer: B — 30 mph

When visibility drops to 100 feet or less, it is unsafe to drive faster than 30 mph.

20. Your car begins to hydroplane on a wet road. What should you do?

Turn the wheel sharply toward dry pavement
Slow down gradually and do not brake
Accelerate slightly to push through the water
Brake firmly to regain traction quickly

Answer: B — Slow down gradually and do not brake

Once hydroplaning starts, the driver should slow down gradually and avoid braking.

21. You come across a flooded section of road with no other route, so you decide to cross slowly. What should you do right after getting through?

Turn on the hazard flashers and stop
Speed up to dry the tires
Shift into neutral and coast to check the engine
Test the brakes

Answer: D — Test the brakes

After crossing a flooded road, the brakes should be tested since water can reduce their effectiveness.

22. You're driving a camper in high winds. What should you avoid doing?

Slowing down
Using cruise control
Holding the wheel firmly
Watching ahead for debris

Answer: B — Using cruise control

In high winds you should slow down, hold the wheel firmly, watch ahead for debris, and not use cruise control.

23. Fog becomes so thick while driving that you can barely see the road at all. What should you do?

Pull off the road, turn on the flashers, and wait
Follow the taillights of the car ahead closely
Speed up to get through the fog zone quickly
Turn on your high beams to cut through the fog

Answer: A — Pull off the road, turn on the flashers, and wait

If fog gets too thick to see through, the safest response is to pull off the road, turn on the flashers, and wait it out.

24. A patrol car turns on its emergency lights and slowly weaves back and forth across the lanes ahead of you to slow traffic. What should you do?

Come to a complete stop immediately in your lane
Flash your high beams to signal you've seen the officer
Turn on your flashers and slow gradually to the officer's speed, without braking suddenly
Pass the patrol car quickly before it fully blocks the road

Answer: C — Turn on your flashers and slow gradually to the officer's speed, without braking suddenly

During a traffic break, drivers should turn on their flashers and slow gradually to the officer's speed rather than braking suddenly.

25. During a traffic break led by a patrol car weaving across the lanes, when is it acceptable to pass the patrol car?

After following at a safe distance for a mile or more
Once you reach a passing zone with a dashed center line
As soon as traffic starts moving normally again, even if the lights are still on
Only after the officer turns off the emergency lights and conditions allow

Answer: D — Only after the officer turns off the emergency lights and conditions allow

Drivers must never pass the patrol car or speed up until the officer turns off the lights and conditions allow it.
