Polk County, for the most part, is a poor county. The revenue they get is from Cable, Telephone (and all communications), Utilities and You Guessed it, Traffic Fines. Each end of the City has posted signs telling you that the City speed is 40MPG. At the North end there is a Business called Benton Shooters Supply with a large lot where police like to sit and nab cars traveling south. Approximately 1/4 mile past that business is the Muni-Building on the left side of U.S. Hwy. 411. Either the police car sits in front of the building catching cars in both directions or they hide behind the Fence (their private parking lot) and go from there. The other two main traps are near the Traffic Signal (Bank Area) whereby the signal changes very fast when a car comes to the light from the east or west side (Main Street) of U.S. Hwy. 411. If the light turns Yellow…Stop and do not try to race under the light or – Ticket. No Wiggle Room. The other trap is on the south where you enter the city on U.S. Hwy. 411. Usually the police car sits off the road to the left facing south U.S. Hwy. 411. If you go 38 up the hill and maintain that speed your usually OK. Police are not all that well trained in these parts and calibation of equipment is an issue. Challange them and save yourself.
