California law requires you to turn on your headlights whenever:

• A.It is cloudy but dry
• B.You are driving in the daytime on a freeway
• C.You need to use your windshield wipers because of weather
• D.Your parking lights are not working

Why

If weather is bad enough to require wipers, it is bad enough to require headlights. Headlights help other drivers see you in rain and spray.
