Is It Legal To Flash Your Headlights To Warn Of Nearby Cops?

    Most drivers in Pennsylvania and New Jersey are aware of the traditional act of flashing your high beams to other drivers to warn them of nearby police speed traps. But many motorists are not aware that the police may attempt to ticket drivers for such action. So, what are your rights when flashing high beams to warn other drivers of police speed traps? Read below for the interesting history and final answer.

    Across the country, each state has their own set of laws which govern driver behavior. However, many states' laws have led to drivers being ticketed for flashing their high beams to warn of an upcoming speed trap.

    A driver in Florida was ticketed for flashing his headlights at oncoming traffic to warn of the nearby police officer. The driver fought the ticket and successfully argued that his conduct was "free speech" as protected by the First Amendment. As a result, Florida enacted a new law clarifying the fact that flashing high beams to alert other drivers is legal in the state. A current lawsuit in Missouri is claiming the same defense.


Pennsylvania

    In Pennsylvania, the issue is not 100% clear.
The Pennsylvania Supreme Court ruled, in 1999, that Pennsylvania law does not allow police officers to ticket a driver who flashes their high beams to alert other drivers during the day. 

    However, no case or law directly addresses the issue of flashing high beams at night. The closest answer is to look to Pennsylvania's general high beam law:
"Whenever the driver of a vehicle approaches an oncoming vehicle within 500 feet, the driver shall use the low beam of light."  75 Pa. C.S.A. Sec. 4306
    Based on a strict interpretation of the law, it is clear that a driver may violate the law by raising their high beams at any point when a driver is within 500 feet in the opposite direction. This law, however, could potentially be challenged as free speech in the same way as the above cases in Florida and Missouri.

New Jersey

    In New Jersey, the law is very clear. In 1999 the Superior Court - Appellate division held that: a motorist may not be convicted of misusing her headlights to warn oncoming motorists of radar. 

    Overall, drivers should always exercise caution with their high beams. Pennsylvania drivers should keep in mind the high beam restriction when a vehicle is approaching in the opposite direction. New Jersey drivers have more leeway, but should always use a prudent approach. While driving through other states, be sure to keep in mind that their state laws may be different than those you are used to in Pennsylvania and New Jersey.

The PA law is pretty much unenforceable anyway. Who determines, or how is it determined if the 500 foot limit has been reached?

BTW, the hyperlink for " 75 Pa. C.S.A. Sec. 4306 " goes to the New Jersey case of State of NJ v Luptak, not to the PA law.

Tom, thanks for the comment. You are right that it can be quite arbitrary to determine the 500 foot threshold. It is left to the officer's discretion, and it's pretty rare that we see an officer issue a ticket unless the high beams are still activated at a very close distance.

Also thanks for pointing out the glitch in the link for the Pennsylvania statute. It's updated now.

It actually seems to be broader than just flashing them to alert motorists of speed traps. It's a First Amendment issue. Even flashing them to indicate that the oncoming driver has HIS high beams on is protected speech.
