Turn your headlights on in bad weather or when you cannot see feet in front of you without them.

The answer varies depending on the state, but generally it is either 500 feet or 1000 feet in front of you.

Explanation:

In California and Alaska, the state law is that you must turn on your headlights if you cannot see 1000 feet in front of you. In Alabama, Indiana, and the District of Colombia, it is 500 feet in front of you.
