When driving behind another vehicle at night, you should:
- Keep your headlights on the low beam setting. ✓
- Use your high beam headlights until you are within 10 feet of the vehicle ahead.
- Use your high beam headlights.
Answer: A. Keep your headlights on the low beam setting.
Keep your headlights on low beam when you are driving behind another vehicle at night.
Why this is the answer
The handbook says your headlights must be on low beam when you are within 200 feet of a vehicle ahead of you, even if that vehicle is in a different lane. It also says to be considerate when using high beams. Following another vehicle at night puts you in the situation where the low-beam rule applies, so keeping low beams is the correct choice.
Why the other answers are wrong
- B. Use your high beam headlights until you are within 10 feet of the vehicle ahead. — The handbook does not set a 10-foot high-beam limit; it requires low beam within 200 feet of a vehicle ahead, so waiting until 10 feet is far too close and conflicts with that rule.
- C. Use your high beam headlights. — Using high beams behind another vehicle conflicts with the handbook rule to dim to low beam within 200 feet of a vehicle ahead.
Remember it
If you can see a vehicle ahead, think low beam: the handbook's 200-foot rule starts well before you get close.
