What Drives Commercial Auto Premium for Heavy Haul Trucking Companies

The five factors that drive Commercial Auto premium for Heavy Haul Trucking Companies

For Heavy Haul Trucking Companies, the underwriting variables that drive Commercial Auto premium fall into a predictable hierarchy. The five factors that do most of the work:

• Commodity hauled (general freight vs hazmat vs auto)
• Three-year auto loss ratio

The Heavy Haul Trucking Companies Commercial Auto pricing factors not on the official list

What underwriters actually look at on Heavy Haul Trucking Companies Commercial Auto

The accept/decline decision is made on the top one or two; if the account passes, schedule-rating credits and debits are applied based on the remaining drivers and the soft factors (documentation, submission quality, etc.).

Understanding this order helps a heavy haul trucking company (and broker) prepare submissions strategically. Lead with the strongest signal on the top driver, then layer in documentation for the supporting factors. The underwriter's job becomes easier, and easier underwriting tends to produce sharper pricing.
