Question 1906

May you drive on a road outside a built-up area with your high-beam headlights on in heavy rain or dense fog?

  1. Yes, because in this case the road is insufficiently lit.
  2. Yes, but it is not advisable because the reflection from the fog or rain could blind you.
  3. No, it is prohibited.
Show answer and explanation

Correct answer: Yes, but it is not advisable because the reflection from the fog or rain could blind you.

Heavy rain or dense fog does not, by itself, prohibit using high beams. However, reflected light can cause glare and worsen visibility, so low beams are usually preferable.
