A Slow Poke Law goes in effect in Tennessee on July 1.
It is designed to keep someone from "camping out" in the fast lane of a highway with three or more lanes.
The law says the fast lane - the one on the far left - is to be used only for overtaking and passing another vehicle.
Those found in violation of the new law are subject to paying a $50 fine.
Rep. Gerald McCormick of Hixson was one of the sponsors.
