The rules vary state by state, so make sure you know the guidelines before you buckle up and drive.
Hazards of the road
You’re driving on local roads and highways on your daily commute. Suddenly, sheets of rain pour down, making what once seemed fine driving weather into an actual hazard. You see in front of you that drivers are turning on their hazard lights, but should you do the same? Read on to learn when you should (and shouldn’t) use your hazard lights. Before you hit the road, brush up on the things you should never do to your car and the weird car features you didn’t know you might have.
First of all, what are hazard lights?
Hazard lights aren’t just for decoration. The experts at the Ford Driving Skills for Life Team (Ford DSFL) tell Reader’s Digest that “the hazard warning function is by FMVSS 108 definition a ‘driver-controlled device which causes all required turn signal lamps to flash simultaneously to indicate to approaching drivers the presence of a vehicular hazard.’ Most state laws are user laws, so they can determine when the user (driver) is permitted to operate them if they choose.” Basically, they’re lights on your car that flash on and off periodically to alert other drivers on the road of a potentially dangerous situation.
