California permit test: night driving and emergencies

See and be seen at night, and know the first steps when something goes wrong.

Key rules

Headlights from 30 minutes after sunset to 30 minutes before sunrise, whenever you cannot see 1,000 feet ahead, and whenever weather requires continuous wipers. (CVC §280, §24400)
Dim high beams within 500 feet of an oncoming vehicle and within 300 feet of a vehicle ahead. Use low beams in fog. (CVC §24409)
At night, drive at a speed that lets you stop within your headlights. Look at the right edge of your lane when blinded, and give room to vehicles with one light. (DMV handbook, Darkness)
