The Valley Claw is a gesture that resembles a wave but with a bit of a flick in the wrist... once you see it, you know. This gesture is done to wave hello, let someone into traffic, etc. It can be witnessed all across the friendly Ottawa Valley.
Driver 1 sees Driver 2 pull out of the Tim's drive thru, waiting to merge into traffic. Driver 1 makes eye contact and tosses the Valley Claw to alert Driver 2 to go ahead into traffic ahead of Driver 1.
