About MC Authorities


With some exceptions, companies that carry passengers or cargo across state lines for compensation must have an Operating Authoirty (also known as an MC Authority).

Upon requesting an MC Authority, companies must get the necessary licensing, insurance and coverage to be approved by the Federal Motor Carrier Safety Administration.

Once approved, the FMCSA sends the new operating authority a letter through the mail, which serves as a license to allow the carrier to operate.

To allow the carrier to get on the road as soon as a week or two earlier, for a small fee MC Authoirty US gets you your letter instantly!
