Two trucking companies with the same number of trucks can get very different quotes. Underwriters are estimating how likely you are to have a claim and how large it could be. These are the things they weigh.
1. Your drivers
Experience and driving records matter more than almost anything else. Underwriters look at years of commercial driving experience, violations and accidents on each motor vehicle report, and how you screen new hires.
2. Your loss history
Past claims are the best predictor of future ones. Clean, current loss runs help; missing loss runs hurt, because the underwriter has to assume the worst.
3. Time in business
A company with several years of continuous coverage and no lapses is easier to place than a new venture. New companies can still get insured, but usually with fewer markets to choose from.
4. What you haul
Some commodities are more likely to be stolen, spoiled or cause severe damage in an accident. Be exact about what you haul so the policy covers it.
5. Where you run
Long-haul routes and congested metropolitan areas carry more exposure than local or regional runs.
6. Your equipment
The age, value and condition of your trucks and trailers affect physical damage pricing.
7. Your safety practices
Written hiring standards, driver training, maintenance programs, and technology such as cameras and telematics show an underwriter that you manage your risk.
What you can control
You cannot change your history, but you can hire carefully, keep coverage continuous, document your safety program and submit a complete application. Those are the things that move a quote.
