Only partially. The MCS-90 endorsement is a federally mandated endorsement attached to commercial auto policies that provides a public-interest backstop up to the financial-responsibility minimums in 49 CFR Part 387 — typically $750,000 for general freight and higher amounts for hazmat. It exists to ensure injured members of the public can recover even when there are coverage disputes. It does not fully shield a broker from negligent-selection claims when the tendered carrier was operating outside its declared parameters or when nuclear-verdict damages exceed the federal minimums. In 2026, the standard of care that brokers are held to in vetting carriers before tender is rising. A broker that relies solely on the MCS-90 endorsement as a substitute for active carrier vetting is taking on legal exposure that did not exist a decade ago.
