Flashing Lights to Warn of Police in Texas: Is it Legal?

"Is it illegal to flash my car's lights to warn others about police ahead in Texas?" This question has sparked countless debates among drivers. While some view it as a friendly heads-up, others see it as a way to dodge law enforcement. So, what does the law in Texas say about this? Let's break it down in simple terms.

Understanding Headlight Flashing

Flashing headlights is a universal language among drivers. It's a quick way to communicate about various road situations, like hazards, wildlife, or even the presence of police. However, the latter has stirred up some controversy. People who disagree argue it's a sneaky way to help lawbreakers avoid getting caught.

The Law in Texas

In the Lone Star State, the law doesn't specifically say that flashing lights to warn of police is illegal. According to the Texas Transportation Code, there are rules about when you can and can't use your high beams. But, there's no clear rule about flashing lights to warn about police.

The Disagreement

Despite the lack of a clear law, this practice has sparked debate. Some argue that it's a form of aiding and abetting criminals. Others see it as a community service, helping drivers avoid costly traffic tickets.

The Legal Grey Area

While the Texas Transportation Code doesn't explicitly outlaw the practice of flashing headlights to warn of police presence, it does contain rules that could possibly be interpreted to cover this situation. For instance, Section 547.305 of the Code states that a motor vehicle lamp or illuminating device, other than a headlamp, spotlamp, auxiliary lamp, turn signal lamp, or emergency vehicle, tow truck, or school bus warning lamp, that projects a beam with an intensity brighter than 300 candlepower shall be directed so that no part of the high-intensity portion of the beam strikes the roadway at a distance of more than 75 feet from the vehicle.

This provision could probably be interpreted to cover the practice of flashing headlights, depending on the intensity of the headlights and how they are directed. However, this interpretation is not clear-cut and would likely depend on the specific situation and potentially the discretion of law enforcement.

The Role of Law Enforcement

Law enforcement agencies in Texas have differing views on the practice of flashing headlights to warn of police presence. Some agencies have been known to issue citations for the practice, while others do not. This difference can confuse drivers about whether the practice is legal or not.

The Importance of Safe Driving

Regardless of the legality of flashing headlights to warn of police presence, it's important to remember that the main purpose of headlights is to ensure safety on the road. Flashing your headlights at oncoming drivers can potentially distract them and cause an accident. Therefore, it's always best to use your headlights in a manner that promotes safety and complies with the law.


So, is it illegal to flash your lights to warn of police in Texas? The short answer is no. There's no specific law against it. But remember, laws can change, and interpretations can vary. Always stay updated on local laws and drive responsibly.

Remember, flashing your lights should primarily be used to ensure safety on the road. Whether it's alerting a driver that their lights are off, warning of a road hazard, or communicating with other drivers, safety should always be your top priority.
