How Insurance Companies Price Commercial Auto Risk
The factors, formulas, and data that determine what you pay for commercial auto insurance.
TL;DR: Your premium equals base rate x classification x territory x experience modifier x driver surcharges, adjusted by endorsements. The most controllable factors are claims history (experience modifier) and driver records (MVR surcharges). Shop carriers annually through an independent broker for the best rate.

The Pricing Formula
Your commercial auto premium is not a random number. It is the result of a pricing formula that combines multiple risk factors. Understanding these factors helps you take specific actions to lower your premium.
At its simplest: Premium = Base Rate x Classification x Territory x Experience Modifier x Driver Surcharges +/- Endorsements
Factor 1: Base Rate
Every state's insurance department approves base rates for commercial auto coverage. These are the starting point before any adjustments. Base rates reflect the overall claims costs in that state. New York has some of the highest base rates in the country due to high medical costs, aggressive litigation environment, and dense traffic.
Factor 2: Classification (Industry/Use)
Your business classification determines your risk tier. Carriers use SIC or NAICS codes to group similar businesses. A law firm with one company car pays less than a plumbing company with one service van because the plumber drives more miles, carries equipment, and works in higher-risk environments.
Factor 3: Territory (Garaging ZIP Code)
Where your vehicles are parked overnight is one of the biggest pricing factors. Carriers divide the country into rating territories. In New York:
- Manhattan/Brooklyn: Highest rates (dense traffic, high theft, expensive repairs)
- Queens/Bronx/Staten Island: High rates
- Nassau County: Moderate-high rates
- Suffolk County: Moderate rates (cheapest in the metro area)
- Upstate NY: Lower rates
Factor 4: Experience Modifier
Your own claims history modifies your premium up or down from the base. Carriers use a loss ratio (claims paid / premium collected) over 3-5 years. A loss ratio under 50% earns credits. Over 75% triggers debits. This is the single biggest controllable factor in your premium.
Factor 5: Driver Surcharges
Each driver's MVR is scored individually. Clean records get no surcharge. Each violation adds points that translate to premium increases. Serious violations (DUI, reckless driving) can make a driver uninsurable with preferred carriers.
Factor 6: Vehicle Characteristics
Year, make, model, GVWR, and age determine replacement cost and risk profile. A new $60,000 truck costs more to insure than a 10-year-old $15,000 van because the potential physical damage payout is higher.
How to Use This Knowledge
You cannot change the base rate or territory factors. But you can control:
- Experience modifier: Prevent claims through safety programs and telematics
- Driver surcharges: Screen drivers aggressively and exclude problem drivers
- Vehicle selection: Choose vehicles with lower GVWR and good safety ratings
- Carrier selection: Work with an independent broker who shops your risk to the carrier that prices YOUR profile most favorably

Why Choose FHIA for Commercial Auto Pricing
We are not a call center or a quoting platform. First Heritage is the managing general agency (MGA) behind FirstClass, our own commercial auto program. If your fleet qualifies, our in-house team makes the underwriting decision under authority delegated by the program’s insurers. If it isn’t a fit for the program, we place it with other carriers we represent. Either way, the same licensed team handles your account from first quote to bound policy.
FirstClass policies are issued by Pennsylvania Manufacturers’ Association Insurance Company (NAIC 12262), Manufacturers Alliance Insurance Company (NAIC 36897), or Pennsylvania Manufacturers Indemnity Company (NAIC 41424) — all members of the Old Republic Insurance Group, each with its principal office in Blue Bell, Pennsylvania. Your issuing company is identified before you bind. Accounts placed outside the FirstClass program are written by other insurance carriers we represent. First Heritage Insurance Agency Inc. is licensed as an insurance producer in New York (licence nos. BR504706 and PC504706).
