Headlight requirements by state

You might think knowing when to turn on your car headlights is simply a matter of common sense, but U.S. laws for headlight use actually vary widely from state to state. With the expanded availability of its Smart Auto Headlights (which respond to weather conditions), Nissan analyzed the headlight regulations throughout the U.S. and created a handy infographic showing when drivers are required by law to turn on their headlights.

The analysis shows that the majority of states require headlight use when visibility is less than 1,000 feet. However, some states require headlights to be used when visibility is 500 feet. Two states, South Dakota and Tennessee, are more lenient, requiring headlights only when visibility is less than 200 feet, while the laws in four states (Louisiana, Massachusetts, Minnesota and South Carolina) stipulate car headlight use only when wipers are in use.

A handful of states, however, have more specific laws for headlight use that could catch an out-of-town driver (or a resident not up on current laws) completely off-guard. The most common requirement is to use headlights when wipers are in use. More obscure requirements include Pennsylvania, which requires drivers to turn on their headlights in construction zones, while Alaska requires headlights at speeds above 45 mph on designated highways.

Because keeping track of state laws can be difficult, owning a car with automatic headlights (which turn on when it's dark) as well as daytime running lights (which use a low beam headlight during the day) can be handy.

All moving vehicles--lights-on, unless you are on tank-duty in enemy territory, good luck!

Everyone should be sure your lights are on in fog, rain snow, dusk!
My wipers on not running at dusk or after dark, except for when it rains!

I can't believe that all the new cars/trucks sold in the US aren't required to have automatic headlights & daylight running lights. Not only are they a great safety feature but it would cut down on the number of STUPID people driving around after dusk without lights...just saw a car last night at 8:30 pm driving down a major road without any headlights!
I wouldn't buy a car without automatic headlights and daylight running lights. Even with these features on my Suburban, I do sometimes have to switch on the lights if driving in rain.

when automatic headlights are on the tail lights are not on. Ask me how dangerous that is in the early morning fog when headlights are coming at u.

Joe, I'm with you: I missed the list, too. Well, maybe we're just suppose to guess-timate?!?
