You must use high-beam headlights in all of the following situations, EXCEPT

Use your high beams whenever there are no oncoming vehicles nearby. High beams let you see twice as far as low beams. Be sure to use high beams on unfamiliar roads, in construction areas, or where there may be people alongside the road. Use low beams in fog, snow, or heavy rain. Light from high beams reflects back from such precipitation and causes glare.
