Howard County, MD Parking Rules: Commercial & Oversized Vehicles (2026)

232 bars parking a commercial motor vehicle on any highway in a residential area of the county for more than six continuous hours at a stretch. 101(g) sweeps in more than obvious box trucks: it covers Motor Vehicle Administration Class C (funeral and ambulance), Class E (truck, including truck-trailer combinations, dump trucks, and tow trucks), Class F (tractor), Class G (trailer), Class H (school), and Class P (passenger bus) vehicles, plus any vehicle used for hauling freight, merchandise, supplies, equipment, or debris in furtherance of a commercial purpose.

Three narrow exceptions apply: vehicles designated as emergency vehicles by the Motor Vehicle Administration, vehicles owned by or under contract to a public utility, and recreational vehicles built to provide temporary living quarters for travel. 213, enforced through a citation from the Police Department or a designated parking enforcement officer. 214 lets the Department of Police impound a commercial vehicle parked in or near a residential area once it accumulates unsatisfied parking citations, either 90 days after a single unresolved citation or 30 days after the most recent of two or more unresolved citations, once the Department of Finance flags the vehicle for impoundment.

The vehicle owner can get it back by paying the outstanding fines, towing, and storage costs, or by showing the Department of Finance the impoundment was improper.
