Truck Weigh & Inspection Operations

The Motor Carrier Division (MCD), in cooperation with the Maryland State Police (MSP) Commercial Vehicle Enforcement Division (CVED), the Maryland Transportation Authority Police (MdTAP) Commercial Vehicle Safety Unit (CVSU) and allied law enforcement agencies certified to enforce motor carrier law is responsible for the safe movement of commercial motor vehicles (CMV) along Maryland highways. The MSP and MdTAP operate 13 TWIS with permanent scales and 4 additional Stations that utilize portable scales to check CMV's for compliance with state and federal safety as well as size and weight requirements. Seven (7) of these sites utilize weigh-in-motion (WIM) devices to pre-screen for weight violations. Additional electronic screening for CMV credentialing (e.g. fuel tax, safety rating, etc.) is being deployed for increased efficiency and effectiveness in maintaining CMV safety. For further information on the Truck Weigh and Inspection Program, call the Motor Carrier Division, 7491 Connelley Drive, Hanover, Maryland 21076, Telephone 410-582-5734.

For further information on the TWIS operated by the MSP, please call the CVED at 410-694-6100. For Stations operated by the MdTAP, please call the CVSU 410-537-1126.

Gross Weight of Vehicles

Based upon Maryland statistical data, 1,800,000 trucks and commercial vehicles are weighed and 95,000 vehicles are inspected each year. Overweight vehicles, in addition to being a potential safety hazard to highway traffic, put a strain on existing pavement and the design life expectancy of roads and bridges. To minimize the damage to bridges and pavement caused by too heavy vehicles, Maryland has adopted the federal bridge formula and table, commonly known as the “Bridge Table” which is detailed on page 102 in the Maryland Motor Carrier Handbook (PDF, 946Kb). Maryland utilizes platform scales and Weigh-In-Motion (WIM) equipment at its TWIS and portable scales at pull-off locations and other sites used by roving enforcement crews.

Width of Vehicles

The maximum allowable vehicle width in Maryland is 102 inches, except when prohibited by posted signs.The width of a vehicle includes any load that it carries and shall be exclusive of safety and energy conservation devices, such as side mirrors, turn signal lamps, marker lamps, steps and handholds for entry and egress. For a detailed description of the Maryland vehicle width law, refer to Title 24, Subsection 102 of the Maryland Vehicle Law.

Height of Vehicles and Loads

The vehicle and load height limit in Maryland is 13’ 6” inches. To obtain hauling permits for overwidth, overheight, or overweight vehicles, contact the State Highway Administration, Motor Carrier Division, Hauling Permits Section at 410-582-5727 or toll-free (within Maryland only) 1-800-846-6435.

Length of Vehicles and Loads

The length of a vehicle includes its front and rear bumpers and any part of its load that extends beyond the vehicle, but is exclusive of non-load bearing safety and energy conservation devices, such as marker lamps, steps and handhold for entry and egress, front-mounted refrigeration units, and front-mounted air compressors. Refer to the Maryland Vehicle Law Title 24, subsection 104.1 for a list of the different vehicle length limits in Maryland .
