Is It Legal in Indiana to Warn Other Drivers That Police are Ahead?

You're driving down the road when you notice an oncoming vehicle flashing its brights at you. Now, if it's at night, that most likely means your brights are on and you need to turn them off, but if it's daytime, the flashing lights almost always mean one thing - there is a cop up ahead. While it may seem like a friendly gesture, you might wonder if it is legal to warn other drivers about a police presence on the road.

I guess the simple answer is yes, that is legal. There is no specific law in Indiana that forbids drivers from flashing their headlights to warn others of law enforcement. However, the situation is a little more complex than a simple yes or no answer.

What Indiana Law Says About Flashing Your Headlights

Indiana’s traffic laws do not explicitly ban flashing headlights to alert fellow drivers about the police. In fact, courts in other states, including some rulings related to free speech rights, have determined the act of warning others about police presence is protected under the First Amendment. While Indiana hasn't had a direct ruling like this, the state's traffic code doesn’t target headlight-flashing for police warnings as illegal.

Having said that, flashing your lights for other "improper" reasons can still get you into trouble. Indiana law prohibits using high beams when they could potentially blind other drivers, so it's crucial to avoid reckless behavior while trying to warn someone.

Potential Consequences for Indiana Drivers

While warning others about police may not directly break the law, it could raise suspicion. Officers might pull you over if they believe you're interfering with traffic enforcement or driving recklessly when flashing your headlights. Here's a friendly reminder - always be cautious when interacting with traffic laws to ensure you stay on the right side of them. You don't want to give law enforcement any reason or excuse to pull you over.

The bottom line is this - warning other Indiana drivers of a speed trap or police car ahead isn't explicitly illegal, but it's best to stay mindful of how you do it. Flashing your lights can be considered free speech in some contexts, but it's smart to use common sense and avoid distractions while driving.
