Questions and Answers Latest Versions Top
Rated A+
1) You’re approaching an intersection with limited visibility. The best defensive
driving strategy is to:
A. Rely on the other driver to stop if needed
B. Slow down and be prepared to stop within your field of view
C. Accelerate to clear the intersection quickly
D. Honk to warn other drivers early
Answer: B
Rationale: Defensive driving means adjusting speed so you can stop if hazards appear within
your view.
2) If you see a driver ahead making sudden lane changes, you should:
A. Move closer to read their brake lights
B. Maintain a larger following distance and be prepared for braking
C. Tailgate them to keep them from cutting in
D. Pass them immediately
Answer: B
Rationale: Sudden maneuvers increase risk; increasing space gives you reaction time.
3) The best time to check your mirrors is:
A. Only when you plan to change lanes
B. Immediately before turning
C. Frequently, as part of ongoing scanning
D. After you’ve already committed to a lane change
Answer: C
Rationale: Continuous scanning helps you detect developing hazards early.
4) Hydroplaning is most likely to occur when:
,A. Tires have good tread depth
B. You drive too slowly in heavy rain
C. Your tires are bald or you drive too fast in water-covered roads
D. You reduce speed and avoid standing water
Answer: C
Rationale: Water between tires and road can reduce traction, especially at higher speeds and
with worn tires.
5) A safe following distance is based on:
A. The posted speed limit only
B. Road conditions and your speed (reaction time needs vary)
C. How impatient the driver behind you is
D. Whether traffic is moving or stopped
Answer: B
Rationale: Following distance must match speed and conditions to allow full reaction and
stopping distance.
6) When approaching a school zone with reduced speed, you should:
A. Keep your speed unless you see children
B. Maintain the posted speed and be ready to stop
C. Use the horn instead of slowing
D. Assume other drivers will stop
Answer: B
Rationale: Children may enter the roadway unexpectedly; slow and be prepared.
7) If a vehicle is not using headlights at dusk, the best response is:
A. Assume they can see you
B. Increase your visibility and be extra cautious
C. Flash your headlights continuously
D. Drive faster to put distance between you
Answer: B
Rationale: Defensive drivers assume other vehicles may be harder to see and adjust accordingly.
,8) You should never drive primarily by:
A. Scanning 12–15 seconds ahead
B. Checking blind spots before lane changes
C. Relying on the “right of way”
D. Keeping your vehicle under control
Answer: C
Rationale: “Right of way” doesn’t prevent crashes; you must still respond defensively.
9) If you miss your exit on a divided highway, the safe action is to:
A. Make a U-turn immediately
B. Use a proper exit and re-route legally
C. Cross the median carefully
D. Stop in a travel lane
Answer: B
Rationale: U-turns or median crossings are dangerous and often illegal; use legal exits.
10) After rain starts, the road surface can be especially slippery because:
A. Water instantly clears away oil
B. Oil and debris rise to the surface early in the storm
C. Tire traction increases automatically
D. Wet roads are always less slippery than dry roads
Answer: B
Rationale: “First flush” of rain can create a temporary slick surface.
11) A pedestrian is walking near the roadway. Defensive driving means:
A. Assume they will always follow traffic rules
B. Slow down and be prepared for unexpected crossing
C. Pass at the last moment to avoid delay
D. Stop only if they look at you
, Answer: B
Rationale: Pedestrians may misjudge speed/distance; anticipate.
12) Which is a primary cause of many crashes?
A. Proper signaling
B. Driver distraction
C. Good tire pressure
D. Following at a safe distance
Answer: B
Rationale: Distraction reduces reaction time and attention to traffic conditions.
13) If you must brake on a slippery road, the best method is:
A. Brake hard immediately to stop fast
B. Brake smoothly to maintain control
C. Pump the brakes lightly
D. Release the brake completely
Answer: B
Rationale: Smooth braking helps maintain stability and traction.
14) For a safe left turn, you should:
A. Turn as soon as the light turns green
B. Check for oncoming traffic and pedestrians even with a green arrow/green light
C. Only check your left mirror
D. Trust that vehicles farther away will slow
Answer: B
Rationale: Signals don’t guarantee other drivers will stop; look for conflicts.
15) Which driving behavior best reduces risk at night?
A. Driving with bright headlights aimed correctly
B. Wearing sunglasses indoors
