Question

It is ten o'clock in the morning on the A28 near Zwolle and there is dense fog. Your driving instructor says: 'In this fog you drive with dipped beam, not with full beam.' Is that true?

Accepted Answer

True — False — you think more light gives more visibility in fog. In the daytime you use dipped beam in dense fog, and full beam is not allowed in the daytime. So the instructor is right.
