Beware, especially those drivers living in urban areas where speed limits generally correlate to population density, street lighting and commercial/residential development. Clarksburg is nothing more than an intersection of two country roads with a convenience store, a branch bank, a honky tonk and a handful of old, mostly run down, homes. Yet it has three shiny police cars who hide at the low end of a speed transition zone from 65 to 40 in less than a mile. If you happen not to see the 55 mph sign lodged between the 65 and the 40 mph signs, you cannot slow fast enough to be at 40 mph by the time you get there. Especially dangerous at night as there is no street lighting or commercial signage to indicate you are entering a township. The road is very wide (5 lanes, 7 counting the paved shoulders) and gives the driver the feeling you are going slower than you really are. Local government depends on speeding fines. This bunch of country rubes will really stick it to you if you are from out of their county. Tennessee Highway Patrol will give a motorist 9 mph over the limit, but Clarksburg’s own “Barney Fife” said, “One mile per hour over, you’re mine, city slicker!”
