The correct answer is B — MCS-90 endorsement. The MCS-90 is the federally prescribed endorsement attached to a motor carrier's liability insurance policy to demonstrate compliance with applicable public-liability financial-responsibility requirements.
The Federal Motor Carrier Safety Administration identifies Form MCS-90 as the Endorsement for Motor Carrier Policies of Insurance for Public Liability under Sections 29 and 30 of the Motor Carrier Act of 1980. FMCSA further states that the endorsement is required under 49 CFR §387.15 for motor carriers subject to the applicable federal financial-responsibility rules.
The MCS-90 is attached to the carrier's liability policy rather than to a specific individual vehicle. Its purpose is to assure payment, within the federally required limits, of qualifying final judgments for public liability arising from negligence in the operation, maintenance, or use of covered motor vehicles.
The Additional Insured-Lessor endorsement deals with leased-vehicle relationships. The Individual Named Insured endorsement addresses particular personal-type coverage needs under commercial auto forms. The Mobile Equipment endorsement addresses equipment that otherwise falls outside ordinary automobile classifications.
The Series 17-70 commercial-auto material includes Motor Carrier coverage, federal financial responsibility, endorsements, liability limits, and commercial automobile forms.
Therefore, MCS-90, option B, is the required endorsement.
