TL;DR: Loss runs are the official reports of your claim history that each insurer keeps: every claim, its date, status, and amounts paid or reserved. Trucking underwriters want three to five years of them, recently valued, before quoting. Request them from each insurer or through your agent, and review them for errors before they price you.
What exactly is a loss run?
A loss run is your insurance claim transcript. Each insurer that has covered you maintains a report listing every claim on your policies: date of loss, coverage involved, description, claim status open or closed, amounts paid, and amounts reserved for what may still be paid. Underwriters read loss runs the way lenders read credit reports, because past claims are the strongest available predictor of future ones. In trucking, where premiums are large and risk varies wildly between operations, no serious quote happens without them.
Why do underwriters care so much about them?
Because loss runs answer the two questions that price an account: how often do claims happen here, frequency, and how bad are they, severity. A pattern of small frequent claims signals loose operations. One large closed claim with a clean record around it reads differently than three open ones. Open reserves matter as much as payments, since the underwriter prices what the claims may still cost. Even the trend line matters: improving years tell a story that a single total number hides.
How do I request my loss runs?
Ask each insurer that covered you in the last three to five years, directly or through your agent. The request is routine: policy numbers, the named insured, and the years needed. Insurers customarily produce loss runs within days to a couple of weeks, and a number of states set legal deadlines for providing them on request. If a prior agent is unresponsive, go to the insurer directly. For periods you had no coverage or no claims, document that too; a no-loss letter fills gaps that would otherwise read as hidden history.
| Step | Detail |
|---|---|
| Identify insurers | Every carrier on your coverage for the last 3 to 5 years |
| Send requests | Named insured, policy numbers, years requested |
| Set the valuation date | Underwriters want reports valued within 60 to 90 days |
| Review before sending | Check for errors, wrong claims, and stale reserves |
| Fill gaps | No-loss letters for uninsured or claim-free periods |
What should I check before underwriters see them?
Read your own file first. Common problems worth fixing: claims that are not yours, attached by error to your account. Closed claims still showing open. Reserves that were set high early and never reduced after the claim resolved cheaply. Subrogation recoveries, money the insurer got back from the at-fault party, not reflected. Each of these inflates the picture that prices you. Ask the insurer's claims department to correct errors and update reserves before the loss runs go to market; a thirty-minute call can be worth real premium.
How do loss runs shape my renewal strategy?
They set the timeline and the story. Request them sixty to ninety days before renewal so marketing starts with fresh reports rather than stalling on document chase. If the runs are clean, they are your leverage: multiple markets pricing verified good history. If they are not, the runs tell you which narrative to bring: what happened, what changed, drivers, cameras, procedures, and why the trend improved. Underwriters respond to explained losses far better than to surprises they find themselves.
Do loss runs follow me when I switch insurers or agents?
Yes. The history belongs to your business, and every future insurer will ask for it regardless of who placed the coverage. Switching insurers does not reset the record, and gaps read worse than explained claims. Keep your own archive: save each year's loss runs when you receive them, so no future renewal depends on a prior insurer's responsiveness years later.
Real questions owner-operators and fleet managers ask
How many years of loss runs do underwriters want?
Three to five years is standard for trucking submissions, from every insurer that covered you in that window, valued recently, typically within 60 to 90 days of the quote. Longer histories help large accounts; shorter ones are expected for young authorities.
How fast can I get loss runs from my insurer?
Customarily within days to a couple of weeks of a routine request, and several states impose legal deadlines for producing them. Going through your agent works; going to the insurer directly works too, especially when a prior agent has gone quiet.
What if my loss runs show a claim that was not my fault?
Fault and coverage are different questions, and the report may still show the claim. Ask the insurer to note subrogation recoveries and closed status, and provide the narrative to underwriters: not-at-fault claims with documentation price far better than unexplained lines.
Do open reserves hurt my quote even if nothing was paid?
Yes. Underwriters price reserves as expected cost. If a claim resolved or a reserve is stale, ask the claims department to update it before marketing. Reducing an outdated reserve is one of the highest-leverage fixes in the renewal process.
What is a no-loss letter?
A short statement, signed by you or issued by an insurer, confirming no claims for a stated period. It fills gaps for uninsured periods or claim-free years a report does not cover, so your submission accounts for every year underwriters ask about.
