Traffic safetyQuestion #15401Multiple correct
When must a driver switch from high beam to low beam?
Explanation
The rules name several situations where high beam must be dipped to low beam to avoid dazzling other drivers: at a certain distance from an oncoming vehicle, when driving on a lit road, and whenever your lights could dazzle others, including drivers ahead of you.
KET reference: KET 95: At night or in poor visibility, high beam must be switched to low beam: on properly lit roads; at least 150 m before an oncoming vehicle; in other cases when it could dazzle drivers.
