Christine V. Anto co-authored "The MCS‐90 Endorsement (The Ultimate Monkey Wrench)" published on December 16, 2011, in In Transit, the Defense Research Institute's Trucking Litigation Committee newsletter.
The article discusses the Federal Motor Carrier Act of 1980 and the result that motor carriers who transport goods in interstate commerce must file proof that they have financial resources to adhere to the minimum levels of financial responsibility. They can satisfy it though three means - MCS-90 endorsement, a surety bond (MCS-82), or self-insurance.
Overall, Christine concludes MCS-90 is not insurance, but should rather be considered a safety net for innocent parties injured by the negligence of the named insured motor carrier. Understanding how the MCS-90 endorsement works should aid the transportation industry in better appreciating and managing their risk.
