To drive defensively, you should
- prepare to stop as you approach a stale green light.
- be alert for vehicles that are about to pass you.
- scan the traffic all around you regularly.
- do all of the above. ✓
Answer: D. do all of the above.
All of the listed habits are part of defensive driving: preparing to stop at a stale green light, watching for vehicles about to pass you, and scanning the traffic all around you regularly.
Why this is the answer
The handbook tells commercial drivers to scan traffic ahead, behind and to their sides constantly, and to use mirror checks to spot drivers who are passing or about to pass. It also says a light that has stayed green for a while is stale, so you should expect it to change and be ready to stop. Since each of the listed behaviors appears in the driving-skills material, doing all of them is the right answer.
Why the other answers are wrong
- A. prepare to stop as you approach a stale green light. — Watching a stale green light and being ready to stop is correct, but it is only one of the defensive habits listed here.
- B. be alert for vehicles that are about to pass you. — Being alert for vehicles about to pass you is correct, but it covers just one part of watching the traffic around you.
- C. scan the traffic all around you regularly. — Regularly scanning all the traffic around you is correct, but on its own it leaves out the other listed habits.
Remember it
Picture defensive driving as a loop: eyes ahead, mirrors behind, sides checked, and a plan for that green light you have been watching for a while.
