Entering Clarksburg TN southbound on Hwy 22 the speed limit rapidly drops from 65 to 40 requiring a quick reaction to avoid a ticket. But the real rub is after putting through this tiny town of little traffic at the 40 mph limit when you pass the last signs of a town and nothing is around you and you are within sight of the 55 mph speed limit sign, DO NOT SPEED UP. While I have never seen this technicality enforced anywhere in my 50 years, the local revenue enhancers (police) of Clarksburg will ticket you for accelerating before you have physically passed the 55 mph speed limit sign. Remain at 40 mph and do not contribute to this towns revenue. I also urge you not to contribute to their revenue by stopping at their one convenience store or BBQ joint. Old figures show they get well over $100,000 a year from speeding fines and driving schools and for a town of 400 people this is absurd. Without a doubt these guys will write tickets for anything they can. make a dollar on. Watch out!!!
