The Illinois Commercial Auto Assigned Risk Plan is operating at a severe underwriting deficit, with combined ratios exceeding 150 percent over the past decade and nearing 191 percent in 2025. Earned premium of roughly $435.7 million has been outpaced by more than $625 million in incurred losses, along with substantial loss adjustment and underwriting expenses. For insurers required to participate in the pool, the gap signals sustained financial strain in a segment already challenged by commercial auto liability trends.
The plan, administered in many states by AIPSO, exists to provide coverage for higher-risk trucking operators that cannot secure insurance in the voluntary market. Industry sources allege some carriers may be underreporting fleet size when applying for coverage, which would distort exposure assumptions and shift costs onto compliant insureds and participating carriers. If accurate, that misrepresentation complicates claims handling, post-loss audits, and coverage verification for adjusters working serious trucking losses.
At the same time, broader pressures remain in play. Nuclear verdicts, severity inflation, and long-tail reserve development continue to challenge commercial auto results nationwide. The surge of new motor carriers during the 2020 to 2022 freight boom introduced many inexperienced operators, and financial stress in the current freight environment may be increasing coverage disputes and fraud concerns.
Recent tightening of application standards and rate adjustments suggest corrective action is underway. For claims professionals, the practical impact is clear: greater scrutiny of exposure accuracy, closer coordination with underwriting and SIU, and continued reserve volatility in Illinois trucking claims until results stabilize.
