NSC Defensive Driving 5 — Questions and Answers
Question 1: What is the correct technique for steering through a curve on a slippery road?
- Accelerate through the curve to maintain traction
- Brake hard before the curve, then accelerate mid-curve
- Reduce speed before the curve and maintain steady throttle through it (Correct answer)
- Steer sharply to exit the curve quickly
Correct answer: Reduce speed before the curve and maintain steady throttle through it
Braking before the curve and applying steady throttle through it keeps weight balanced and maximizes available traction.
Question 2: Under NSC guidelines, what is the minimum recommended sleep before a long highway drive?
- 4 hours
- 6 hours
- 7–8 hours (Correct answer)
- 5 hours
Correct answer: 7–8 hours
NSC recommends 7–8 hours of sleep before driving to ensure alertness, as drowsy driving impairs reaction time comparably to alcohol.
Question 3: What is the safest position to hold a steering wheel for airbag-equipped vehicles?
- 10 and 2 o'clock
- 9 and 3 o'clock (Correct answer)
- 8 and 4 o'clock
- 11 and 1 o'clock
Correct answer: 9 and 3 o'clock
The 9 and 3 position keeps hands away from the airbag deployment zone and provides better steering leverage.
Question 4: When driving through a work zone, which of the following is most important?
- Matching the speed of other vehicles in the zone
- Obeying posted work zone speed limits and watching for workers (Correct answer)
- Staying in the left lane to avoid workers on the shoulder
- Speeding up to clear the zone quickly
Correct answer: Obeying posted work zone speed limits and watching for workers
Work zone crashes are often fatal for workers; posted reduced speed limits and constant alertness for workers on foot are critical.
Question 5: What does 'vehicle dynamics' mean in a defensive driving context?
- The engine horsepower output under load
- How a vehicle's weight shifts during acceleration, braking, and cornering (Correct answer)
- The aerodynamic drag of a vehicle's body
- The fuel consumption rate at varying speeds
Correct answer: How a vehicle's weight shifts during acceleration, braking, and cornering
Understanding weight transfer helps drivers predict how their vehicle will respond to inputs and avoid loss of control.
Question 6: Which of the following distractions is classified as 'cognitive' in NSC's distracted driving framework?
- Adjusting the radio dial
- Eating while driving
- Talking hands-free on a cell phone (Correct answer)
- Looking at a map on the dashboard
Correct answer: Talking hands-free on a cell phone
Hands-free calls are cognitive distractions because mental focus shifts away from driving even though hands remain on the wheel.
Question 7: If your vehicle's ABS activates during emergency braking, you should:
- Pump the brake pedal to help the system
- Release the brake pedal to reset the system
- Maintain firm brake pressure and steer around the hazard (Correct answer)
- Press harder, then release in pulses
Correct answer: Maintain firm brake pressure and steer around the hazard
ABS does the pumping for you; keeping steady firm pressure lets ABS maintain maximum braking force while you steer to avoid the hazard.
