NSC Defensive Driving 3 — Questions and Answers
Question 1: What is 'road rage' and how should a defensive driver respond to an aggressive driver?
- Match the aggressive driver's speed to stay safe
- Avoid eye contact, do not retaliate, and create distance (Correct answer)
- Flash your lights to signal them to back off
- Report them via cell phone while driving
Correct answer: Avoid eye contact, do not retaliate, and create distance
Retaliating escalates danger; the safest response is to disengage, avoid eye contact, and increase the gap between vehicles.
Question 2: What is the primary purpose of the 'space cushion' concept in defensive driving?
- To allow other drivers to merge more easily
- To provide time and space to react to unexpected hazards (Correct answer)
- To reduce fuel consumption by drafting
- To comply with minimum following distance laws
Correct answer: To provide time and space to react to unexpected hazards
A space cushion gives you reaction time and maneuvering room to avoid crashes when hazards appear suddenly.
Question 3: At what blood alcohol concentration (BAC) does the law presume impairment for drivers 21 and older in all US states?
- 0.05%
- 0.08% (Correct answer)
- 0.10%
- 0.12%
Correct answer: 0.08%
All 50 states set the legal BAC limit for adult drivers at 0.08%, above which impairment is legally presumed.
Question 4: Which of the following best describes 'controlled intersection' in NSC defensive driving?
- An intersection with no traffic controls
- An intersection managed by signals, signs, or officers (Correct answer)
- An intersection on a private road
- An intersection with only yield signs
Correct answer: An intersection managed by signals, signs, or officers
A controlled intersection has official traffic controls such as signals, stop signs, or traffic officers directing vehicles.
Question 5: What should a driver do when merging onto a highway from an on-ramp?
- Stop at the end of the ramp and wait for a gap
- Match highway speed and merge smoothly into a gap (Correct answer)
- Force highway traffic to slow down for you
- Use the shoulder to extend your acceleration distance
Correct answer: Match highway speed and merge smoothly into a gap
Matching highway speed before merging reduces speed differentials that cause rear-end collisions.
Question 6: What does SIPDE stand for in the defensive driving decision-making process?
- Speed, Identify, Predict, Decide, Execute
- Scan, Identify, Predict, Decide, Execute (Correct answer)
- See, Indicate, Proceed, Decelerate, Evaluate
- Slow, Inspect, Position, Drive, Exit
Correct answer: Scan, Identify, Predict, Decide, Execute
SIPDE — Scan, Identify, Predict, Decide, Execute — is a systematic process for managing driving hazards.
Question 7: What is the recommended action when you experience a tire blowout at highway speed?
- Brake hard immediately to stop quickly
- Grip the wheel firmly, ease off the gas, and steer straight while gradually braking (Correct answer)
- Swerve toward the shoulder immediately
- Shift to a lower gear right away
Correct answer: Grip the wheel firmly, ease off the gas, and steer straight while gradually braking
Hard braking after a blowout can cause a spin; maintaining control and gradually decelerating keeps the vehicle stable.
