Is flashing your headlights legal in Alabama? Here’s what the law says
How much does it cost to fix damage to your car from a pothole?
Springtime is often the season of potholes. Here are some tips to keep your tires safe from damage.
A quick flash of your headlights can catch someone’s attention faster than a horn. On busy or quiet streets, it’s a simple, wordless way drivers communicate.
Sometimes it’s a quick “thanks,” a warning or just a mystery. But is this way of communicating legal? Here’s what Alabama law says about flashing headlights.
Is it legal to flash your headlights at other cars in Alabama?
Yes, in Alabama, it technically is legal to flash your headlights at another car. There are no laws that explicitly say it’s illegal. However, some codes prohibit the use of high beams.
Alabama law says drivers must use low beams when within 500 feet of oncoming traffic or 200 feet of the vehicle ahead. These rules help everyone see clearly and stay safe.
Is flashing headlights to warn drivers of speed traps a form of free speech?
See a speed trap? Flashing your headlights to warn others is common. Is it legal? The Free Speech Center at MTSU notes that courts have protected this as free speech.
In 2012, Michael Elli of Ellisville, Missouri, was pulled over for warning of a speed trap by flashing his headlights. Officials said he hindered police, but later agreed he did not.
Other similar cases were Elliott v. Warrick County in 2014 and Beaver v. City of Federal Way in 2018.
