The Department’s proposal would establish safety standards requiring all newly manufactured U.S. trucks, buses, and multipurpose passenger vehicles with a gross vehicle weight rating more than 26,000 pounds to come equipped with speed limiting devices.  Motor carriers operating commercial vehicles in interstate commerce would be responsible for maintaining the speed limiting devices at or below the designated speed for the service life of the vehicle under the proposal.

Is a "multipurpose passenger vehicle" a motorhome?
