Arkansas Truck Mud Flap Law
Arkansas requires a flexible splash apron behind the rearmost wheels of any truck, tractor, trailer or semitrailer over 10,000 pounds GVWR (Rule 17.3, 27 CAR 110-1803). It must hang perpendicular, parallel to the axle, and be big enough to keep road spray off a following windshield. The rule sets no inch-clearance and no width number, so Arkansas Highway Police judge it by whether spray is controlled. A missing or shredded apron is a correctable equipment citation, not an out-of-service defect.
