Maryland Trucking Laws

The Federal Motor Carrier Safety Regulations (Title 49, Parts 350-399) govern all vehicles engaged in interstate traffic.

There are some situations where a tractor-trailer or other commercial motor vehicle is involved in only intrastate travel. For example, an appliance store in Bethesda may own a truck that only makes in-state deliveries.

The Maryland Department of Public Safety has adopted Title 49, Parts 382-384 and 390-399 of the federal regulations.

The following provisions are an overview of Maryland laws that affect trucks operating only in Maryland:

Driver Qualification

Maryland has adopted Part 391 of the Federal Regulations with some modifications. Part 391 does not apply to a farmer in the transportation of supplies or farm products within 150 air miles of the farm.

A driver not meeting the physical qualification requirements may qualify for a waiver. Contact the Motor Vehicle Administration for specifics regarding a waiver possibility.

Parts and Accessories

Maryland has adopted Part 393 of the Federal Regulations. Factory installed pollution control devices must be maintained in constant operation. It is illegal to disconnect or otherwise interrupt their operation.

Loads

Maryland has adopted Part 393 of the Federal Regulations, including regulations dealing with projecting and shifting or falling loads. All vehicles must be constructed or loaded in a way that prevents any of the load from dropping, sifting, leaking, or otherwise escaping from the vehicle.
