Commercial Auto Insurance Loss Ratios by State: 2026
In 2023, commercial-auto insurers ran a 74.4% loss ratio and lost 13.5% on underwriting — the worst of the 8 major commercial lines. That's why trucking and delivery rates keep climbing.
Source: NAIC 2023 Report on Profitability by Line by State (public regulator data). Loss ratio = incurred losses ÷ premiums earned; a higher loss ratio (and negative underwriting profit) means the line is less profitable for carriers, which drives rate increases.

Methodology
Figures are from the NAIC 2023 Report on Profitability by Line by State — the National Association of Insurance Commissioners' public compilation of insurer financial results. Loss ratio is incurred losses divided by premiums earned; underwriting profit reflects the insurance result after expenses. We rank states worst-first by loss ratio and report commercial auto's rank among the major commercial lines by national loss ratio — the "worst line" framing is the computed rank, not an assertion. These are aggregate carrier economics, not a quote for any individual business.
