No one flashes their lights in Ohio, they just cut in about a foot in front of you anyway. Even if there are no other cars on the road for miles ahead or behind.Posted by BarbC:
Where I learned to drive in NJ, on the turnpike and parkway, flashing one's headlights means get out of the left lane or your going to lose your front bumper when he cuts back in front of you.
Once in a while cars will flash their lights if I'm in the left lane passing someone that is going slower than me. I ignore them or slow down a little if I'm going the speed limit. I took an oath to enforce and uphold the laws of this worthless state and I'm not about to abet any idiots that can't read a speed limit sign. They should have left earlier.
