Connecticut Truck Mud Flap Law
Connecticut requires suitable metal protectors or flexible flaps behind the rearmost wheels of any bus, truck, truck-tractor, full trailer or semitrailer over three tons registered weight (Conn. Gen. Stat. 14-104). If the rear wheels aren't already covered by fender or body, cover them at the top and rear. The statute sets no inch clearance and no width number. A violation is an infraction. Roadside, an officer checks the flap is present and effective, not a precise dimension.
