Going South on US Hwy 281, just before the Bitters Rd Exit, A policeman will operate a tripod mounted laser to read your speed from either the side of the road or from the bridge overhead. He then radios to patrol cars waiting further down. This setup is hard to spot because we normally look for a patrol car parked on the side of the highway. Unlike traditional radar, this laser unit allows them to hit cars that are very close together – they can get 3 or 4 cars in a line if they are all speeding.
