1. What is the primary goal of defensive driving?
A. Driving as fast as possible
B. Preventing collisions by recognizing and responding to hazards
C. Avoiding all highways
D. Driving only during daylight
Answer: B. Preventing collisions by recognizing and responding to hazards
Rationale: Defensive driving emphasizes recognizing potential and immediate hazards and
making decisions that reduce the likelihood of collisions. NSC specifically emphasizes hazard
recognition and collision-prevention strategies.
2. Which factor is most directly controlled by the driver?
A. Weather
B. Road construction
C. Driver behavior and decisions
D. Another driver's actions
Answer: C. Driver behavior and decisions
Rationale: Drivers cannot control weather, road conditions, or other motorists, but they can
control their own speed, attention, following distance, and decisions.
3. A defensive driver should primarily:
A. React only after a hazard becomes dangerous
B. Anticipate potential hazards before they become emergencies
C. Assume other drivers will always obey the law
D. Drive faster than surrounding traffic
Answer: B
Rationale: Defensive driving is proactive. Recognizing developing hazards early gives the driver
more time and space to respond.
,4. Which behavior increases crash risk?
A. Maintaining adequate following distance
B. Scanning ahead
C. Distracted driving
D. Adjusting speed for conditions
Answer: C. Distracted driving
Rationale: Distraction reduces the driver's ability to detect hazards, process information, and
respond appropriately.
5. What does "space management" mean in defensive driving?
A. Keeping adequate space around the vehicle
B. Parking only in large parking lots
C. Driving only in the right lane
D. Leaving space exclusively in front of the vehicle
Answer: A
Rationale: Space management involves maintaining usable space around the vehicle so the
driver has time and options to respond to hazards.
6. Why is following distance important?
A. It improves fuel economy only
B. It provides time and distance to react if traffic slows or stops
C. It allows the driver to use a phone
D. It eliminates the need to scan ahead
Answer: B
Rationale: Adequate following distance creates a safety buffer and increases the driver's
available response time.
7. What is a hazard?
A. Anything that can increase the possibility of a collision or injury
B. Only a stopped vehicle
,C. Only bad weather
D. Only a traffic violation
Answer: A
Rationale: Hazards can include vehicles, pedestrians, road conditions, weather, poor visibility,
objects, and driver behaviors.
8. Which is an example of a potential hazard?
A. A pedestrian approaching the edge of a roadway
B. An empty parking lot
C. A properly functioning traffic signal
D. A clear road with no traffic
Answer: A
Rationale: A pedestrian near the roadway may enter the driver's path. Recognizing the potential
hazard early allows the driver to prepare.
9. Which is an immediate hazard?
A. A vehicle suddenly entering your lane
B. A distant billboard
C. A parked car several blocks away
D. A clear sky
Answer: A
Rationale: An immediate hazard requires prompt driver attention and potentially an immediate
response.
10. What is the best response when another driver behaves aggressively?
A. Compete with the driver
B. Make eye contact and challenge the driver
C. Avoid escalating the situation and create distance
D. Follow the driver closely
Answer: C
, Rationale: Defensive driving emphasizes avoiding unnecessary conflict. Creating distance and
remaining calm can reduce the risk of a road-rage incident.
11. What is the safest attitude toward other drivers?
A. Assume they will make no mistakes
B. Expect that other road users may make errors
C. Assume everyone is inexperienced
D. Treat every driver as an opponent
Answer: B
Rationale: Defensive drivers anticipate mistakes by other road users and maintain enough space
and awareness to respond.
12. Which activity is a form of driver distraction?
A. Scanning mirrors
B. Checking traffic ahead
C. Texting while driving
D. Maintaining a safe following distance
Answer: C
Rationale: Texting diverts visual, manual, and cognitive attention from driving and significantly
reduces situational awareness.
13. Why is texting particularly dangerous while driving?
A. It only affects hearing
B. It diverts attention away from the driving task
C. It improves reaction time
D. It makes the vehicle easier to control
Answer: B
Rationale: Texting can simultaneously require visual attention, manual interaction, and cognitive
attention, leaving fewer resources available for driving.
