This video shows a trucker using a flashlight to signal a motorist. According to the video description, the motorist had “no idea why. My high beams weren’t on, nor the car behind me. I wasn’t speeding, there was no speed trap further down the road. It was the first and only time I passed him, just driving along normal. Maybe it was intended for the car behind me, but I can’t figure out why he was doing that. Maybe a trucker out there can shed some light on it. Pun kinda intended.”
