Is Flashing Your Lights to Warn of Cops Illegal?: 1 Minute to Understand the Legal Implications

Flashing your headlights to warn oncoming drivers about police presence or speed traps is a common practice among drivers, but its legality depends on where you are. In the United States, there is no federal law specifically prohibiting this act. However, different states and municipalities interpret the practice—and enforce laws—differently. In some states, flashing your lights is seen as protected free speech, while in others, it can be considered obstruction of justice or a violation of laws regarding the improper use of vehicle lighting.

For example, courts in Florida and New Jersey have ruled in favor of drivers, arguing that warning others about speed traps is a form of free speech. Some states, however, may cite drivers for improper use of headlights, especially if the act is deemed distracting or if it involves high beams that could interfere with other motorists' safety. It’s always best to check your state's specific laws to know your rights on the road.
