A higher loss ratio means carriers paid out more of each premium dollar in claims, which tends to push Illinois commercial auto rates up and thin the field of carriers competing for the business; a lower one signals a more profitable, more competitive market. With a 2.0% underwriting loss, Illinois carriers relied on investment income to make the line work in 2023 — a sign of rate pressure ahead. Counting investment income, carriers earned a 5.7% profit on commercial auto insurance transactions in Illinois in 2023 — NAIC's broadest profitability measure for the line. Either way, these are industry aggregates — your own commercial auto rate depends on your business, and the only way to see it is to compare filed rates and real quotes.
Illinois's $1.9B in commercial auto premiums is the 7th-largest of the 51 states NAIC reports for the line. Across those states, loss ratios span from 99.1% in California — the toughest market for carriers — down to 40.1% in Hawaii, the most profitable; Illinois's 67.9% places it 22nd of 51. For buyers, a state near the top of that spread usually means firmer commercial auto pricing and fewer competing carriers, while a state near the bottom tends to run softer and more competitive. By premium, Illinois is about 4.7% of the $40.9B national commercial auto market, and its loss-ratio rank places it in the harder half of states for carrier profitability — context that shapes how aggressively carriers compete for Illinois commercial auto business.
