Getting pulled over by a police officer can be nerve-wracking. As the flashing lights reflect off your rearview mirror, your mind races, and you may notice something that seems out of place: the officer reaches out and touches your car’s tail lights. Why do they do that? Is there some hidden meaning or reason behind this subtle gesture? In this article, we’ll uncover the fascinating reasons why police officers always touch the car’s tail lights during traffic stops.
