Posted limit in town is 30 mph. As you leave and are in the wide open spaces a 55 mph sign appears in the distance. Natural tendency is to begin to speed up. If you begin to increase speed before the 55 mph, they’ll nab you (and it is technically their right to do that). Tickets are outrageously expensive. Since it was the end of the month and I was from out of state, I was a great target. This was only my third ticket in 30+ years of driving. Got my second one less than a year ago though!
