Explanation
Low beam headlights must be used between sunset and sunrise, unless there are no other drivers or pedestrians nearby who could be blinded by high beams. They should also be used during poor weather conditions, such as fog, rain, or smoke. It is best not to use high beams in fog, as the light may reflect off the fog and impair the driver’s vision.
