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.
