What rating basis does Umbrella / Excess Liability use for Auto Transport Carriers?

Umbrella / Excess Liability for Auto Transport Carriers is rated per $1M of underlying limit — that is the unit of exposure carriers use to scale premium against operations. The base rate per unit comes from ISO loss costs, refined by each carrier with its own experience.

Two adjustments do most of the work after the base rate: your experience modifier (which captures three years of paid claims relative to expected losses) and the schedule rating credits or debits an underwriter applies based on operational quality.

How ISO codes shape your Umbrella / Excess Liability premium

Umbrella / Excess Liability rating for Auto Transport Carriers starts with the ISO class code mapped to the operation. The code controls the base rate per $1M of underlying limit, which is then adjusted by experience modifiers and carrier-specific multipliers.

Class-code disputes are a common reason for premium overages — a auto transport carrier placed in a higher-rated cousin class can pay 20-40% more than necessary. Asking the broker to confirm the assigned class code before binding is the single fastest premium audit.

What limits should Auto Transport Carriers carry on Umbrella / Excess Liability?

Limit selection on Umbrella / Excess Liability for Auto Transport Carriers is mostly driven by contract requirements and risk-tolerance — not premium. Moving from $1M to $2M per occurrence on the same risk typically adds only 15-25% to premium because the loss distribution above $1M is thin for most motor carrier risks.

If your contracts already require $2M, buying the lower limit and stacking umbrella to reach $2M effective limit is usually cheaper than carrying $2M primary outright. Coverage Axis routinely models both structures and lets the client pick the cheaper math.
