A single total loss is the scenario most owners picture, and it's often not the one that hurts most. The pattern that more often strains a fleet is several mid-sized claims in one policy year: a backing hit at the supply house, a cracked windshield, a sideswipe on a narrow job-site road, a cut-out catalytic converter. Each one typically costs the full deductible.
- Pull three to five years of loss runs and count the physical damage claims in each year, not just the dollars.
- Multiply your worst year's count by each deductible you're considering.
- Compare the result with what the higher deductible is quoted to save in premium.
- Check it against the cash the business could spend in a bad month without delaying payroll or a supplier.
- Run the test separately for comprehensive and collision, since theft, glass and weather losses tend to follow their own pattern.
Lenders get a vote, too. Financed and leased trucks usually come with a maximum deductible and a loss payee requirement written into the finance agreement, so read those documents before settling on a figure the lender might not accept.
