We found out a few weeks ago that it is illegal for you to flash your headlights at an oncoming vehicle in Illinois, but is it illegal in Missouri?

Everyone should know that driving courtesy of dimming your lights when you pass another car is legal (and encouraged to do so). However, if you are caught using your headlights other than diming them for oncoming traffic, that is illegal.  According to a book released from the Missouri Driver Guide,

•Use your high beams when there are no oncoming vehicles. Do not overdrive your headlights...Use your low beams when you come within 500 feet (about one block) of an oncoming vehicle. Also use your low beams when following another vehicle within 300 feet.

If you are caught flashing your lights, other than dimming them it could get you a ticket. Flashing lights at another driving are considered aggressive driving in the state of Illinois, so you will want to be careful and think before you flash your headlights.

Just like Illinois, it did not say anything about warning another driver about a police officer by flashing your lights, but in my experience (yes I have been pulled over for that) I wouldn't do it. I just got a warning and no ticket. Hey, I was a teenager I didn't know any better but haven't done it since.

Be careful when you think flashing your lights is a good thing, I guess if you don't get caught but is that a chance you want to take?
