Why is commercial auto insurance so expensive for heavy truck fleets?
Commercial auto insurance is expensive for heavy truck fleets mainly because accidents involving heavy trucks tend to be severe, and the cost of resolving those claims has risen sharply. A loaded mixer, dump truck, or tanker carries far more weight than a passenger vehicle, so when it's involved in a crash, injuries are often serious and property damage is significant.
Several things compound that. Medical and repair costs have increased. Litigation has become more aggressive, with plaintiff attorneys using techniques designed to put trucking companies and their safety practices on trial. Large jury awards, often called nuclear verdicts, have changed how insurers estimate the cost of a serious claim. Insurers also price for the venues where you operate, and some jurisdictions are considered much less favorable to defendants than others.
On top of that, fewer insurers want to write heavy-truck classes like concrete, aggregates, and oilfield hauling. Less competition generally means less pricing flexibility.
The things you control still matter. Loss history, driver hiring standards, training, maintenance, telematics, and how you use camera footage all influence how underwriters see your fleet. A well-documented safety program won't make heavy-truck insurance cheap, but it can make a real difference in how your account is priced and which markets are willing to compete for it.
