IS IT ILLEGAL TO FLASH YOUR HEADLIGHTS TO WARN OF A SPEED TRAP IN MISSOURI?

SPEED TRAP

If you’ve ever flashed your headlights at an oncoming car to warn them about a speed trap up ahead, you’re not alone. In fact, some drivers feel it’s just part of the unofficial “driver code.”

But here’s the real question:

“Is flashing your headlights to warn other drivers illegal in Missouri?”

The answer? It depends. The law isn’t exactly crystal clear, but Missouri courts have weighed in and if you’re not careful, you could still end up pulled over or even ticketed.

If you’re dealing with a pesky Missouri traffic ticket, give Speeding Ticket KC a call today and talk to one of our experienced Kansas City traffic defense lawyers. We can help you  navigate the often confusing Missouri legal system and help you get your record cleaned up.

WHY DRIVERS FLASH THEIR HEADLIGHTS

Most of the time, headlight flashing is used to:

  • Warn of speed traps or police up ahead
  • Signal to move over or go ahead at intersections
  • Communicate road hazards or emergencies

But even if it feels helpful or downright neighborly — law enforcement doesn’t always appreciate it.

WHAT DOES MISSOURI LAW SAY ABOUT FLASHING HEADLIGHTS?

Missouri doesn’t have a specific statute that says, “It is illegal to flash your headlights to warn of police.” However, drivers have been cited under other laws, such as:

  • Improper use of vehicle lighting (RSMo § 307.120)
  • Obstruction of justice or interference with law enforcement
  • Unlawful use of high beams (especially if within 500 feet of another vehicle)

The good news?: In 2014, a federal court in Missouri ruled that flashing headlights is a form of free speech protected under the First Amendment. In Elli v. City of Ellisville, the court held that the act of warning other drivers by flashing headlights is not illegal and that citing a driver for doing so violates constitutional rights.

Still, that doesn’t mean officers won’t pull you over or try to cite you under another provision. That’s where things can get messy.

CAN I STILL GET PULLED OVER?

Yes. Despite the court ruling, police in some Missouri jurisdictions still stop drivers for headlight flashing — especially if they can argue that:

  • Your brights blinded another driver
  • You obstructed an investigation or interfered with enforcement
  • You violated a local ordinance

And even if the headlight warning charge doesn’t stick, you could walk away with:

  • A secondary citation for something else
  • A court appearance
  • Points on your license if it’s combined with a moving violation

WHY YOU SHOULD HIRE AN EXPERIENCED MISSOURI TRAFFIC LAWYER

If you’ve already been ticketed….Don’t panic — but don’t ignore it either. Headlight-related tickets can be challenged, reduced, or dismissed, especially with the 2014 court ruling as precedent and strong legal argument from a trusted Kansas City traffic attorney.

Trying to defend yourself in court? That’s where things go from clever to costly. Even if your ticket seems minor, a conviction can mean:

  • Points on your license
  • Insurance rate increases
  • A record of interference with law enforcement
  • A headache in court if you’re not familiar with legal language or defenses

At Speeding Ticket KC, we know how to fight tickets tied to:

  • Improper headlight use
  • Speed trap-related stops
  • Local ordinances abused by overzealous policing
  • First Amendment violations

We’ll handle the court, the paperwork, and the negotiations—so you don’t have to stress or guess.
