Question 4415
If a cloud of smoke significantly reduces visibility, must any type of lighting be used?
- Yes, the front fog light or the low or high beams.
- No, except between sunset and sunrise.
- Only when oncoming vehicles approach.
Show answer and explanation
Correct answer: Yes, the front fog light or the low or high beams.
If smoke greatly reduces visibility, lighting is mandatory at any time, including during the day and even if no one is coming toward you. You must use your position lights and, at the front, your front fog lights, low beams, or high beams, without blinding anyone. You must turn on the rear fog light only if the smoke is dense. In the image, the car coming out of the smoke has its lights on in broad daylight.
