The short answer
Start with the contract. Then look beyond its minimums.
CHP 2026–27 Tow Service Agreement: auto liability minimums are $750,000 combined single limit for Class A and $1,000,000 for Classes B, C and D, including hired and non-owned autos. On-hook minimums are $50,000, $100,000, $200,000 and $250,000 for Classes A through D. Garage liability is at least $500,000. Garagekeepers must meet the matching on-hook minimum, with proof for every listed storage facility.
CHP rotation requires an admitted insurer. For California-based operators, the agreement calls for a California-admitted insurer. The policy must provide at least 30 days’ written notice to CHP before cancellation or expiration. A certificate alone does not change the policy. Source: CHP agreement, section 14.
Agero’s published minimums: commercial auto and general liability each range from $300,000 to $1,000,000 per occurrence. On-hook is $100,000 to $150,000. Garagekeepers is $100,000 to $150,000 when storing vehicles. Service, volume, client and state requirements can mean higher limits. Source: Agero insurance requirements.
Your rate depends on the trucks, drivers, contracts, territory, loss history and yard exposure. Meeting a contract minimum does not establish that the limit fits your operation.
