Which of the following is NOT in the defensive driving chain of events?

• A. Perception
• B. Reaction
• C. Expectation
• D. Hesitation

Answer: (D)

Defensive driving relies on a smooth sequence from noticing a potential hazard to taking timely action. You perceive the situation, which triggers your mental assessment of what could happen. You form an expectation about how other road users might behave and what outcome is likely, so you’re ready to respond. Then you decide on a safe course of action and carry it out—for example, braking or steering to avoid danger. Hesitation doesn’t fit this flow because it introduces a delay between noticing a hazard and acting. That pause can allow the hazard to change or worsen, making safe avoidance much harder and undermining the proactive nature of defensive driving. Perception gets you aware of the risk, reaction is the physical response, and expectation helps you anticipate what might happen so your response is appropriate. Hesitation, by contrast, is the pause that undermines timely, decisive action.
