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

Section 287-7 of the Charles County Code defines HEAVY COMMERCIAL VEHICLE as any motor vehicle and tandem axle trailer or semitrailer used for freight, merchandise, or commercial purposes that has a gross vehicle weight over 10,000 pounds, a manufacturer's rated capacity over one ton, a length over 21 feet, or a height over eight feet, excluding government-owned vehicles and farm equipment. Section 287-8C(3) prohibits parking heavy commercial vehicles, utility trailers, or buses on a public roadway where truck, trailer and bus parking is prohibited by official signs, with narrow exceptions: a vehicle actively loading or unloading, a vehicle used by an owner working on abutting property, a bus stopped 30 minutes or less at an authorized terminal, a vehicle disabled by mechanical failure or emergency for 48 hours or less, or a permitted public contractor's vehicle.

Section 287-8C(4) lets the county post those no-parking signs on a local road or minor collector inside the Development District, a Planned Unit Development, or a Waterfront Planned Community Zone, where the road abuts residentially zoned property, if a majority of abutting property owners or the neighborhood's homeowners' association requests it in writing, or if the County Commissioners deem it appropriate on their own.
