MC Authority & MCS90 Your Trucking Insurance Guide #truckinginsurance #truckingindustry
In this segment, Hunter Nelson explains that carriers with an active MC (Motor Carrier) authority are required to carry the MCS‑90 endorsement, which mandates that all trucks—whether owned, operated, or owned by independent owner‑operators—must be listed on the carrier’s auto liability policy. The auto liability coverage follows the MC number, meaning any truck associated with the carrier is covered while it is in transit or handling a load as defined by the bill of lading. Additionally, the carrier’s cargo insurance policy is also linked to the bill of lading and includes the carrier’s name, extending cargo coverage to the same loads. The explanation emphasizes the regulatory linkage between MC authority, the MCS‑90 endorsement, and both auto liability and cargo insurance coverage.
