FMCSA Truckload Weight/Size Regulations

Learn about FMCSA regulations and weight/size restrictions for dedicated truckload equipment.

In general, the maximum weight limit for commercial motor vehicles is 80,000 pounds, including the weight of the vehicle and its cargo. However, there are certain exceptions to this rule, such as for vehicles that carry specialized loads like oversized equipment. The maximum size limit for commercial motor vehicles also varies depending on the state and the specific route being traveled. In general, the maximum length limit for combination vehicles is 80 feet, while the maximum height limit is 13 feet 6 inches. The maximum width limit is 8 feet 6 inches, although certain states allow for wider loads with special permits.

It's important to note that there are also regulations specific to refrigerated trucks, such as requirements for temperature monitoring and control. Carriers and drivers should ensure that their vehicles are compliant with all applicable regulations before operating on public roads.

Flatbeds are a type of CMV that is used primarily for transporting large or oversized loads that cannot be transported in a standard enclosed trailer. Flatbeds are subject to weight and size restrictions that are similar to those for dedicated truckload equipment. The FMCSA requires that flatbeds be no longer than 53 feet in length, no higher than 13.5 feet in height, and no wider than 8.5 feet in width. However, flatbeds may be allowed to exceed these restrictions if they obtain a special permit from the FMCSA. 

In addition to these general weight and size restrictions, the FMCSA also sets specific restrictions for certain types of cargo. For example, CMVs that transport hazardous materials are subject to additional safety regulations, such as requirements for specialized equipment and training for drivers. 

It is important to note that weight and size restrictions for CMVs may vary depending on the state in which the vehicle is operated. Some states may have stricter weight and size restrictions than those established by the FMCSA, while others may have more lenient restrictions. Operators of dedicated truckload equipment and flatbeds should be aware of the weight and size restrictions in each state in which they plan to operate.
