Top Definition
A specific road violation in which, while making a left-hand turn onto a double-laned road, the driver immediately pulls into the right lane instead of properly turning into the left lane and then, with blinker, merging into the right lane. The term is named after the Canadian city "Thunder Bay" in which this aforementioned violation is rampant and part of everyday driving.
In a hurry, he pulled a Thunder Bay, not noticing the vehicle on the ramp that wanted to merge onto the road.
