Question 5284

If you are driving and have doubts about the lighting conditions, what should you do?

  1. If in doubt, turn on the high beams.
  2. If in doubt, turn on the low beams.
  3. If in doubt, turn off the lights to avoid causing glare.
Show answer and explanation

Correct answer: If in doubt, turn on the low beams.

If you're unsure whether there's enough light to see and be seen, turn on your low beams without waiting until it's completely dark. They let others see you and, if properly adjusted, won't blind anyone. High beams can blind others, and with your lights off, you're harder to see.
