St. Matthews has a very long 30 mph speed limit where such a speed is only necessary for the short business district. The speed limits changes from 55 to 30 mph. Few motorists decelerate quickly enough to get under 40 upon coming into town. Upon leaving town the tendency is to speed up in the long 30 mph zone. The town police cars are camped in hiding with the radars fixed on the 30 mph signs. They give "careless driving" citations and fines of $100 if 10 mph over limits which is not reported to the state nor the insurance companies. An officer told me had made eight such citations in a two hour period.
