How Insurance Companies Underwrite Commercial Auto Policies
What underwriters look at, why your premium is what it is, and how to present your business for the best rate.
TL;DR: Insurance underwriters evaluate your industry, driver MVRs, 3-5 year claims history, vehicle types, garaging ZIP codes, operating radius, and cargo type to price your policy. Claims history and driver records are the most controllable factors. Present a complete application and use an independent broker.

What Is Underwriting?
Underwriting is the process insurance carriers use to evaluate your business, assess risk, and determine whether to offer coverage and at what price. The underwriter reviews your application, loss history, driver records, vehicles, and operations to assign a risk classification that drives your premium.
What Underwriters Evaluate
1. Business Classification (SIC/NAICS Code)
Your industry determines your base rate. Construction contractors, delivery services, and transportation companies pay more than office-based businesses because their vehicles face higher risk exposure. The classification code on your policy must accurately reflect your operations.
2. Driver Records (MVR)
Underwriters pull Motor Vehicle Reports for every driver on your policy. Clean MVRs get preferred rates. Violations increase premiums: speeding tickets add 5-15%, at-fault accidents add 20-35%, and DUI/DWI can make a driver uninsurable with preferred carriers. Driver requirements guide.
3. Loss History (Loss Runs)
Your 3-5 year claims history is the single biggest factor in your premium. Underwriters look at claim frequency (how many), severity (how expensive), and loss ratio (claims paid vs. premium collected). A loss ratio under 50% is excellent; over 75% triggers concern; over 100% means the carrier is losing money on your account.
4. Vehicle Details
Year, make, model, GVWR, VIN, and intended use all affect pricing. Newer vehicles cost more to insure (higher replacement value). Heavier vehicles (higher GVWR) generate larger claims. Specialized vehicles (dump trucks, reefers) carry higher risk profiles than standard work vans.
5. Garaging Location
Where your vehicles are parked overnight significantly affects rates. Vehicles garaged in NYC pay 30-50% more than those on Long Island due to higher accident frequency, theft rates, and repair costs.
6. Radius of Operation
How far your vehicles travel from their base. Local operations (under 50 miles) are cheapest. Regional (50-200 miles) costs more. Long-haul (200+ miles) is the most expensive because more miles driven = more accident exposure.
7. Cargo Type
What your vehicles carry matters. General tools and equipment are standard. Hazardous materials, high-value goods, and perishables increase risk and premium.
How to Get Better Underwriting Results
- Present a complete, accurate application. Incomplete applications get declined. Inaccurate ones get rescinded after a claim.
- Clean up driver records. Remove or exclude drivers with poor MVRs. Implement defensive driving training.
- Show loss improvement. If you have had claims, demonstrate what you have done to prevent future ones (telematics, safety programs, driver training).
- Provide fleet photos. Clean, well-maintained vehicles signal a well-run operation.
- Use an independent broker. FHIA knows which carriers are writing aggressively for your industry and risk profile. We present your account to the right markets.

Why Choose FHIA for Commercial Auto Underwriting
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).
