NSC Defensive Driving Course Exam
Questions & Detailed Answers| Latest Update
,Question 1. According to the National Safety Council, defensive driving is
best defined as:
A. Driving fast enough to keep up with traffic flow at all times
B. Driving to save lives, time, and money despite the conditions around you
and the actions of others
C. Driving only during daylight hours to avoid hazards
D. Driving strictly according to posted speed limits regardless of conditions
Correct Answer: B
Rationale: The NSC defines defensive driving as driving to save lives, time,
and money, in spite of the conditions around you and the actions of others. It
requires anticipating hazards and adjusting behavior proactively rather than
simply reacting or rigidly following rules regardless of context.
Question 2. What are the three most common contributing factors in
collisions, according to defensive driving research?
A. Weather, road design, and vehicle age
B. Driver error, distraction, and impairment
C. Excessive speed only
D. Poor vehicle maintenance only
Correct Answer: B
Rationale: The vast majority of collisions are caused primarily by human/driver
error, including inattention, distraction, impairment, and poor decision-making,
rather than by vehicle or road factors alone; addressing driver behavior is the
core focus of defensive driving training.
Question 3. The 'space cushion' concept in defensive driving refers to:
A. The distance maintained around a vehicle on all sides to allow time to
react to hazards
B. The amount of legroom inside the vehicle
C. The distance between the driver's seat and the steering wheel
, D. The trunk space available for cargo
Correct Answer: A
Rationale: A space cushion is the area maintained around a vehicle (front,
rear, and sides) that provides the driver with time and room to see hazards,
react, and maneuver safely, which is a cornerstone principle of defensive
driving.
Question 4. Which acronym is commonly taught in defensive driving
courses to describe the visual scanning and decision-making process?
A. IPDE (Identify, Predict, Decide, Execute)
B. STOP (Stand, Turn, Observe, Proceed)
C. FAST (Focus, Assess, Steer, Turn)
D. GO (Gas, Observe)
Correct Answer: A
Rationale: IPDE stands for Identify, Predict, Decide, and Execute — a
systematic process defensive drivers use to identify potential hazards, predict
how they might affect the driver, decide on the best course of action, and
execute that action smoothly and in time.
Question 5. In the IPDE process, the 'Predict' step involves:
A. Physically braking the vehicle
B. Anticipating what a hazard is likely to do and how it could affect your path
of travel
C. Signaling a lane change
D. Checking mirrors only
Correct Answer: B
Rationale: The Predict step requires the driver to mentally anticipate the likely
actions of an identified hazard (such as a pedestrian, vehicle, or road
condition) and how those actions could create a conflict with the driver's
intended path, before deciding how to respond.
Question 6. The Smith System's 'Aim High in Steering' principle means:
, A. Looking only at the vehicle directly ahead
B. Looking well ahead of the vehicle (12-15 seconds) to identify potential
hazards early
C. Steering with the eyes closed briefly to relax
D. Keeping the headlights on high beam at all times
Correct Answer: B
Rationale: Aiming high in steering means looking far down the road (about
12-15 seconds ahead in normal driving) rather than fixating close to the
vehicle, which allows earlier hazard detection, smoother steering, and more
time to react.
Question 7. Which of the following best describes 'getting the big picture'
as a defensive driving habit?
A. Focusing narrowly on the vehicle directly in front
B. Continuously scanning the entire driving environment, including mirrors,
gauges, and surroundings
C. Only checking the rearview mirror before braking
D. Watching only oncoming traffic
Correct Answer: B
Rationale: Getting the big picture involves maintaining broad situational
awareness by continuously scanning the road ahead, to the sides, and behind
(via mirrors), as well as monitoring instrument gauges, to detect hazards early
and avoid tunnel vision.
Question 8. The Smith System principle 'Keep Your Eyes Moving' is
intended to prevent which hazardous habit?
A. Highway hypnosis / target fixation on a single point
B. Excessive mirror checking
C. Frequent lane changes
D. Overuse of turn signals
Correct Answer: A
