Federal Judge Rules Flashing Lights to Warn of Speed Trap is Protected Free Speech

Police cannot punish drivers for flashing their headlights to warn others of speed traps, a federal judge has ruled (pdf) in a case involving the First Amendment.

 

The ruling arose after police in Ellisville, Missouri, ticketed Michael Elli for using his headlights to inform motorists that officers were lying in wait to ticket those exceeding the speed limit.

 

The American Civil Liberties Union (ACLU), which sued on behalf of Elli and other drivers, argued that the plaintiffs’ actions constituted a form of free speech.

 

U.S. District Judge Henry Autrey agreed with the ACLU and granted a preliminary injunction that prevents Ellisville police from ticketing or arresting any more motorists for flashing their headlights.

 

Autrey wrote that the officer in Elli’s case “did not have reasonable suspicion to believe that Plaintiff had violated any law” and that it was not illegal to warn drivers “because a speed trap is ahead.”

 

Other towns have tried to do the same thing with motorists warning each other.

 

ACLU Legal Director Tony Rothert said the ruling, the first of its kind in the nation, should apply everywhere. If not, the civil liberties group may file more lawsuits.

 

“We’re going to hope that they take note of the court’s order. And if we hear about it happening after today, we will contact them, and ask them to stop,” Rothert told the St. Louis Post-Dispatch.

 

Eugene Volokh, who teaches free speech law at UCLA, says he’s not sure if Elli’s and others’ actions are covered under the First Amendment.

 

“Whether this is the right answer is not clear. The situation is a special case of warnings to hide one’s illegal conduct because the police are coming — ‘abort the plan to rob the store’ or ‘flush the drugs down the toilet,’” Volokh wrote in The Washington Post.

Flashing one's lights serves a public safety interest, which a speed trap does not. A speed trap is primarily about handing out tickets to raise revenue. That's why officers hide behind hills and hedges, to snare the unwary. The zone of wary drivers is kept as small as possible. Flashing of lights, on the other hand, causes people to slow down well in advance, miles in advance even, of the actual speed trap --- the slowing down and extra alertness of drivers increases safety. Police should view "flashers" as adjuncts of the speed trap, extending its public safety mission for miles in both directions --- rather than party poopers who spoil the officers' fun.
