Mt. Prospect gains a ton of revennue because of their ridiculously extended 30 mph speed zone on NW Hwy. When headed southeast, the limit is lowered to 30 by the Shell station, which is several blocks before Central, and nearly a mile before Downtown Mt. Prospect. When headed northwest, it is lowered by Bruce’s Automotive shop, which is a half a mile from Downtown MP. They primarily run radar from the metra parking lots,the shell station, bruce’s automotive, orthe fire station. It looks like a normal parked car at first, but its not until after he has clocked your speed that you realize its a cop. Watch out for unmarked silver and black crown victorias also. Also, don’t speed to or past 40 until you passed the 40 sign.
