I own an older, well-built pickup truck with a solid I-beam rear bumper. To date, I have jammed on my brakes three times when speeders tailgate my vehicle. Am I breaking the law doing what I do. Yes, I realize I am, but I am fed up with tailgaters, red light and stop sign runners and flat-out traffic lawbreakers. When will the police start ticketing these violators. Again, I realize that I am no better, but I am FED UP with self-centered, all about me careless drivers.
