California DMV Permit Test (Class C)Safe Driving PracticesMedium
You are driving on a multi-lane highway. To practice defensive driving, how far ahead should you typically scan the road for potential hazards?
- A10-15 seconds ahead to allow for early detection and reaction.
- BAs far as you can see, regardless of traffic conditions.
- C1-2 seconds ahead to focus on immediate traffic.
- D5-6 seconds ahead to anticipate upcoming events.
Show answer & explanationAnswer & explanation
Correct answer: A. 10-15 seconds ahead to allow for early detection and reaction.
Defensive driving involves looking well ahead to identify potential hazards and situations that may require a response. Scanning 10-15 seconds ahead, which typically translates to about a quarter-mile on the freeway, provides ample time to react safely to changing conditions.
Why the other options are wrong
- B. While looking as far as you can see is good, the '10-15 seconds' rule is a practical and measurable guideline for defensive scanning.
- C. 1-2 seconds is too short and only allows for reactive driving, not defensive driving.
- D. 5-6 seconds is better than 1-2, but still not optimal for anticipating hazards on a highway.
