NSC DEFENSIVE DRIVING COURSE —
EXAMINATION
120 Multiple-Choice Questions with Answers and Rationales
1. What is the core definition of defensive driving?
A. Driving faster than traffic to avoid conflicts
B. Driving so as to prevent collisions in spite of the incorrect actions of others and
adverse conditions
C. Driving only in daylight hours
D. Driving with maximum insurance coverage
Correct Answer: B
Rationale: Defensive driving is defined as driving to save lives, time, and money despite
the conditions around you and the actions of others.
2. Which of the following best describes the goal of a defensive driver?
A. To never be involved in a collision, even one caused entirely by another driver
B. To arrive at the destination as quickly as possible
C. To always have the right of way
D. To follow other vehicles as closely as possible to save time
Correct Answer: A
Rationale: A true defensive driver anticipates hazards and adjusts driving to avoid
collisions, regardless of who would technically be at fault.
3. The three key elements of collision avoidance taught in defensive driving are
recognizing a hazard, deciding on a course of action, and:
A. Blaming the other driver
B. Executing the action in time
C. Reporting it to police first
D. Waiting for the hazard to pass
Correct Answer: B
Rationale: Recognition, decision, and timely execution form the collision-avoidance
sequence; failing to act in time defeats early recognition.
,4. What does the acronym SIPDE stand for in defensive driving?
A. Scan, Identify, Predict, Decide, Execute
B. Stop, Inspect, Park, Drive, Exit
C. Signal, Indicate, Pass, Drive, Ease
D. Steer, Idle, Push, Drift, Engage
Correct Answer: A
Rationale: SIPDE (Scan, Identify, Predict, Decide, Execute) is a systematic process for
processing information while driving.
5. A collision is generally defined by safety professionals as:
A. An unavoidable act of God
B. An unplanned event resulting from an unsafe act, condition, or a combination of
both
C. Only an event involving injury
D. Any event where a vehicle stops suddenly
Correct Answer: B
Rationale: Collisions are treated as preventable, unplanned events caused by unsafe
acts or conditions, not as random accidents.
6. What is a 'preventable collision'?
A. One where the driver failed to do everything reasonable to avoid it
B. One that involved another vehicle
C. One that happened on a highway
D. One that occurred at night
Correct Answer: A
Rationale: A collision is classified as preventable if the driver failed to act reasonably to
avoid it, even if another party was legally at fault.
7. Which attitude is most associated with safe, defensive driving?
A. Impatience
B. Overconfidence
C. Tolerance and patience toward other road users
D. Competitiveness
Correct Answer: C
Rationale: Patience and tolerance reduce the likelihood of aggressive reactions that
lead to poor decisions and collisions.
,8. Why is attitude considered as important as skill in defensive driving?
A. Attitude determines how a driver applies their skills and knowledge in real
situations
B. Attitude has no real effect on driving
C. Skill alone always prevents collisions
D. Attitude only matters for new drivers
Correct Answer: A
Rationale: A driver may have excellent skills but a poor attitude (impatience, aggression)
can override good judgment and lead to unsafe decisions.
9. What is the 'space cushion' concept in defensive driving?
A. A cushion installed in the driver's seat
B. Maintaining an open area of space around the vehicle to allow time to react to
hazards
C. The distance between the steering wheel and the driver
D. A term used only for parking
Correct Answer: B
Rationale: Keeping space on all sides of the vehicle (front, rear, and sides where
possible) gives the driver room and time to maneuver away from danger.
10. Which of the following is NOT one of the four main categories of driving errors
that lead to collisions?
A. Faulty observation
B. Wrong assumptions
C. Poor vehicle color choice
D. Improper reaction (too slow or too fast)
Correct Answer: C
Rationale: Vehicle color has no bearing on driver error; the recognized categories
involve observation, judgment, decision-making, and reaction.
, 11. What is the minimum following distance recommended under ideal conditions
using the time-based method?
A. 1 second
B. At least 3 seconds
C. 10 seconds
D. There is no recommended method
Correct Answer: B
Rationale: The 3-second rule provides a minimum buffer under good conditions; it
should be increased in poor weather, heavy traffic, or when following large vehicles.
12. How should following distance be adjusted when driving in rain or fog?
A. It should be reduced to save time
B. It should be increased beyond the standard 3 seconds
C. It should stay exactly the same
D. It only matters at night
Correct Answer: B
Rationale: Reduced traction and visibility in rain or fog require additional following
distance (often 4-6 seconds or more) to allow for longer stopping distances.
13. When being tailgated, what is the recommended defensive action?
A. Brake suddenly to warn the tailgater
B. Speed up to get away as fast as possible
C. Increase your own following distance and, if safe, allow the tailgater to pass
D. Ignore it completely and maintain the same following distance
Correct Answer: C
Rationale: Increasing your own cushion in front reduces the need for sudden braking,
and letting the tailgater pass removes the hazard safely.
14. Total stopping distance is the sum of which two components?
A. Perception distance and reaction distance only
B. Perception-reaction distance and braking distance
C. Speed and vehicle weight
D. Tire pressure and road grade
Correct Answer: B
Rationale: Total stopping distance equals the distance traveled while perceiving and
reacting to a hazard plus the distance needed to brake to a stop.
