11 CSR 50-2.300 - Mud Flaps
(1) Trucks
without rear fenders, which are intended to be registered for over twenty-four
thousand pounds (24,000 lbs.) must be equipped with mud flaps for the rear
wheels. Mud flaps must be wide enough to cover the full tread width of the
tires. Mud flaps must be installed so that they extend from the underside of
the vehicle body in a vertical plane behind the wheels to within eight inches
(8") of the ground, except that mud flaps on dump trucks must be installed so
that they extend from the underside of the vehicle body in a vertical plane
behind the wheels to within twelve inches (12") of the ground. Mud flaps must
be sufficiently rigid to provide adequate protection when the vehicle is in
motion.
(2) Fenders installed by
the manufacturer on all pickup trucks and other small trucks will be
recognized. Curved fender wells, such as those on gasoline delivery trucks,
van-type trucks, and any other truck with a fender design that provides
reasonable protection to the rear of the vehicle, will be exempt.
(3) Reject vehicle if-
(A) Not equipped with required mud
flaps;
(B) Flap is not wide enough
to cover the full tread width of the tire(s);
(C) Flap is not in a vertical plane extending
to within twelve inches (12") of the ground for dump trucks; or

to within eight inches (8") of the ground for all other vehicles that require
mud flaps.
