Dooly County Sheriff Department targets motorists along I-75 in the area where construction is taking place. The speed limit drops from 70 mph to 60 mph. The thing that makes this a speed trap is that the Dooly County Sheriff Department preys upon motorist in this area on weekends when absolutely no workers are present and no construction is taking place. During this time period, the speed limit should not be enforced. They are taking advantage of motorists to raise revenue. The fine is $298 . Wow!
