What are DOT Decals on Vehicles for?

DOT decals are used to identify commercial vehicles that are registered with the Federal Motor Carrier Safety Administration (FMCSA). The decals must be displayed on the front and back of the vehicle, and they must be at least 2 inches high. The decals include the vehicle's USDOT number, which is a unique identifier assigned to the vehicle by the FMCSA.

The FMCSA requires commercial vehicles to be registered with the agency in order to operate in interstate commerce. The registration process includes providing information about the vehicle, the owner, and the operator. The FMCSA uses this information to track commercial vehicles and to ensure that they are in compliance with federal safety regulations.

The USDOT number is used by law enforcement and other officials to identify commercial vehicles. The number can be used to access information about the vehicle, such as its registration status and its inspection history. The number can also be used to track the vehicle's movements.

DOT decals are an important part of the FMCSA's efforts to ensure the safety of commercial vehicles. The decals help to identify commercial vehicles and to track their movements. This information can be used to prevent accidents and to enforce safety regulations.
