Can Flashing Your High Beams Change a Traffic Signal?
Big Jim used to be a fireman/paramedic and told us a secret about traffic lights. If you flash them with your high beams from the right distance, you can get them to change! Now, if you Google it, you'll find places like SNOPES.com saying it isn't true. What do YOU think?
The logic is that the lights have reflectors designed to sense the approach of emergency vehicles.
