This is a high enforcement area! Cobb County and GP Officers are always somewhere, either northbound or southbound, at all times of the day. They are especially fond of under the Hwy 5 overpass (267) for 1/2 mile north in the northbound lanes (toward 268). The officer sits in the center of the highway, usually around a mild corner, sampling speed at a surprise distance of about 750 feet. Speed limit is 65 mph, but officers regularly get persons doing 85 or more. You are safe at a speed of 8 mph above the speed limit, but do not let others push or hurry you along.
