Trucking Insurance for California Operators.

MCS-90 is a federally-required endorsement on trucking auto liability that ensures the carrier will pay third-party claims even if the insured violated policy terms. Required for FMCSA-authorized interstate trucking. The carrier can recover from the insured after paying, but the third party gets paid. It's filing-only, not actual additional coverage — but without it, you can't operate interstate.

Cargo insurance is first-party — it pays for cargo damage regardless of fault, up to the policy limit. Motor truck cargo legal liability is third-party — it covers your legal liability to the cargo owner when you're at fault. Most trucking operations carry first-party cargo (the shipper expects it); brokers often carry MTC legal for the loads they arrange.

Trucking workers' comp uses several codes depending on operation: 7219 for trucking under 3 tons, 7229 for over 3 tons, 7230 for trucking with stop-and-go delivery operations, 7228 for trucking long-distance. Rates are high — trucking is one of the higher claim-frequency industries in workers' comp. Correct class coding matters enormously at audit.

USDOT numbers identify FMCSA-registered carriers. Insurance carriers pull your USDOT number's safety scores, crash history, and inspection results during underwriting. A bad CSA score (Compliance, Safety, Accountability) can mean higher premiums or non-renewal. We help newer operations get coverage before their CSA scores develop and help established operations manage the carrier relationship through CSA changes.

Trucking auto liability is rated heavily on driver MVR — accidents, moving violations, hours-of-service violations, DOT inspection results. A single major violation (DUI, reckless, hit-and-run) typically triggers non-renewal. Multiple minor violations push premium up significantly. We help operations build hiring criteria that protect the rate, and we shop markets when an existing driver creates rating problems.

When you pull a trailer that's not yours under a trailer interchange agreement, your auto liability won't cover damage to that trailer. Trailer interchange coverage fills the gap. Common in dedicated lane operations, drop-and-hook freight, and arrangements with brokers who supply trailers. Required by many trailer interchange agreements.

Owner-operators can elect to be covered or excluded from their own workers' comp. Many fleets require owner-operators to carry occupational accident insurance instead (cheaper but provides less benefit). California specifically has restrictions on excluding owners — we structure this carefully because misstructured ownership can lead to uninsured injury claims.

FMCSA rules apply to interstate trucking. California intrastate trucking is regulated by CHP and CPUC with somewhat different requirements but generally similar minimum liability limits. We confirm whether you're interstate, intrastate, or both — and structure compliance for the right authority.
