In Alabama, you must dim your headlights whenever you are within ________ of an oncoming vehicle.

Explanation

High beams can blind the driver of an oncoming vehicle. Under Alabama law, you must dim your headlights to low beam whenever you're within 500 feet of an oncoming vehicle or within 200 feet of a vehicle you are following. Avoid shining your high beams on any other occupied vehicle. If you dim your high beams before they can shine on other vehicles, those other drivers may extend you the same courtesy.
