1. There are police in the area trying to catch speeders

The first reason is one I'm sure you've heard before. Another driver is trying to alert you that a police officer is in the area.

It's an act of courtesy. It may be serving as a warning that there's a speed trap ahead, so head the warning and watch out. You may want to slow down a little.

2. It's dark and your lights aren't on

The second reason could be that it's getting dark or is dark enough that you should have your own headlights on.

3. You have a headlight out

Some drivers simply use it as a way to get the other driver's attention and then will point at something wrong with the person's car, like a headlight being out, or they've left their cup of coffee on the roof after leaving Starbucks, Dunkin', or wherever. You laugh, but, I've seen it.

4. There's a hazard on the road ahead

Take warning. There may be something on the road ahead that could affect your drive...a dead animal, a tree down, or some other debris.

It is legal to flash your lights at another driver

You may have heard it's illegal to flash your lights at another driver, and if a cop catches you doing it, you'll get a ticket.

Wrong.

It used to be against the law in some states but the ACLU came to the defense of people across the country, arguing it was simply a way for drivers to communicate.
