Summary of requirements
Owner-operators leased to a carrier operate under the carrier’s authority and USDOT number. There is no need for the owner-operator to have a separate DOT number unless the owner operator will also operate as a carrier under their own authority.
An owner-operator that has leased themselves and their vehicle to a carrier, must mark the vehicle with the carrier’s legal name (or tradename if included on the carrier’s MCS-150) and USDOT number.
