As anyone who has ever driven on the turnpike in Ohio the posted speed limit of 65 is never followed but strictly enforced. The trap sets up using an airplane to attain your speed. They use calibrated stop watches and lines painted on the road every 1/4 mile. (This method is illegal in most states!) Your fuzz busters are worthless for this type of enforcement. The ground unit is parked either along side the road behind a bridge or around the bend out of sight and is not running radar so you don’t see him until he’s behind you with his lights on. My best advice is watch for the lines painted along side the road at mile marker 116 and check the air for people with stop watches.
