We serve clients across Florida and work with multiple insurance carriers to help individuals, families, and business owners compare coverage options that fit their state and industry requirements.
Reviews reflect individual customer opinions and experiences. They do not guarantee specific coverage, pricing, service timing, or claim outcomes.
A loss run is a record of your claims history, and carriers use it to evaluate a risk before quoting it.
What a loss run may show
The report commonly identifies policy periods, dates of loss, claim numbers, drivers or vehicles, cause or description, paid amounts, reserves, recovery information, and open or closed status. Formats differ by insurer, and a report may not contain the complete claim file.
Check that the business name, policy periods, and requested valuation date are correct. An old report can omit later payments, recoveries, reopened files, or claim closures.
How to request loss runs
Contact the current or prior insurer or agent and request currently valued loss runs for the period required by the prospective insurer, often several policy years. Provide the exact legal entity, policy numbers, policy dates, and authorized contact information. Ask whether the receiving underwriter needs the reports sent directly by the insurer.
Start early. Carrier response times vary, and open claims or old policies can require follow-up. Do not wait until the day before renewal.
Reconcile the report with the business’s records
Compare every entry with accident reports, vehicle files, driver assignments, repair documents, and correspondence. Identify incorrect drivers, duplicate claims, wrong dates, or claims that should be closed. Ask the insurer to review an error; do not edit the carrier’s report yourself.
If a claim remains open, learn what information is missing and who owns the next step. An open reserve does not necessarily equal the final payment, but it may affect underwriting until the file changes.
Add factual context without rewriting history
Explain what happened, which vehicle and driver were involved, the current status, and any documented operational change. Examples include new backing procedures, changed driver assignment, camera installation, maintenance controls, or revised accident reporting.
Do not minimize an incident, speculate about blame, or promise that a new control will eliminate claims or reduce premium. Underwriting decides how to evaluate the record.
Use loss patterns to improve operations
Several small backing claims can indicate yard or jobsite-control issues. Repeated windshield or glass claims can show route and parking exposure. Theft can reveal overnight-security concerns. The business can use these patterns for training, routing, maintenance, and vehicle assignment even when the insurance result is uncertain.
Loss-run request checklist
- Exact legal entity and any prior names
- Current and prior policy numbers
- Required years and current valuation date
- Contact authorized to receive the reports
- Open-claim status and adjuster information
- Accident reports and internal incident records
- Factual explanation of corrective actions
- Deadline for renewal or new quote
Distinguish paid amounts, reserves, and total incurred
“Paid” is generally the amount disbursed to date. A reserve is an insurer’s estimate for future claim obligations and can change. “Total incurred” commonly combines paid amounts and outstanding reserves, subject to the carrier’s reporting format. Do not describe a reserve as money already paid or a final claim value.
When an underwriter asks about a large open claim, provide the current report and factual status. Do not pressure an adjuster to close a legitimate file solely for quoting purposes. If the report appears stale, request an updated valuation or written clarification.
Build a five-year claim timeline
For each policy period, list every reported event, including glass or small physical-damage claims when they appear on the carrier record. Match the date, driver, vehicle, location, cause, paid amount, reserve, and status. Add a column for documented operational response.
This timeline helps identify recurring patterns and prevents the owner from forgetting a claim when completing an application. An omission can appear inconsistent even when it began as a memory problem.
Protect the integrity of the documents
Save carrier-issued PDFs with the date received and do not edit them. Transmit them through a secure method because they may contain business and claim information. Limit access to staff who need the record, and follow the company’s document-retention and privacy procedures.
At renewal, request new reports early enough to correct missing periods. If the business changed insurers, obtain runs from each carrier. When an entity was renamed, merged, or reorganized, explain which policies and claims belong to the current operation.
Loss runs are one part of underwriting. MVRs, accident reports, claim narratives, current controls, vehicles, drivers, and the insurer’s appetite can also affect the decision. A clean report does not assure a quote, and a claim does not automatically make an account uninsurable.
What to send with a difficult loss history
Provide the carrier-issued report, declarations for the matching periods, police or incident reports when available, photographs, claim-status correspondence, and a short factual narrative. Identify which driver and vehicle were involved and whether either remains with the business. If a procedure changed, attach the dated policy, training record, maintenance log, or other proof.
Avoid character judgments or unsupported claims that the other party was fraudulent. Underwriters need a consistent record. A concise chronology with documents is more credible than a long explanation that conflicts with the loss run.
Frequently asked questions
Are loss runs the same as a driver MVR?
No. Loss runs report claims tied to insurance policies; an MVR reports a driver’s motor-vehicle record from the applicable authority.
Can I obtain a quote without loss runs?
You can often get a rough price, but most carriers want loss runs before they finalize and bind the policy. A new business with no prior commercial policy is the exception, since there is nothing to report.
What if the report is wrong?
Send documentation to the insurer or agent and request correction or an explanatory response. Preserve the original report and correspondence.
How far back should I request?
Plan on the last three to five years of commercial auto coverage, dated within the last 60 to 90 days. Some carriers ask for less, so confirm the exact number of years with your agent before you request them.
