Endorsement for Motor Carrier Policies of Insurance for Public Liability under Sections 29 and 30 of the Motor Carrier Act of 1980. 

The MCS 90 is an insurance endorsement required by federal regulation under 49 CFR § 387.15 and mandated by Sections 29 and 30 of the Motor Carrier Act of 1980 (49 U.S.C. § 13906).

The MCS 90 endorsement is not issued for individual vehicles. Instead, it is attached to the motor carrier’s liability insurance policy and applies to all vehicles operated under that policy which are subject to the federal financial responsibility requirements.
