Semi truck insurance claims: what happens after you call
Most truck owners read their policy twice: when they buy it, and after something goes wrong. This guide is for the second time: what the policy asks of you after a loss, what the insurer controls, and where claims stall.
Written by Rigo Diaz
A truck claim in numbers
A semi truck insurance claim starts with prompt notice to your insurer, and from then on the policy sets the rules. The insurer defends and settles liability claims against you, pays your truck's damage at the lesser of actual cash value or repair cost, and can refuse coverage if you skip your duties.
A claim is the moment a policy stops being a price and becomes a contract. The wording you skimmed when you bought it now decides who talks to the injured driver, how your truck gets valued, and whether you get paid at all.
I spent more than six years in risk management before I founded Simplex, and I have led it for more than 25 years since. This guide follows the conditions in ISO's standard business auto form, which spell out your duties and the insurer's after an accident. Read it next to your own policy, because yours may use different wording.

Key takeaways
Your duties are conditions of coverage
The standard form says the insurer has no duty to provide coverage unless you fully comply with the duties after a loss, starting with prompt notice of how, when, and where it happened.
Don't pay or promise on your own
Any payment, obligation, or expense you take on without the insurer's consent is at your own cost.
The insurer runs the liability defense
It has the right and duty to defend covered suits and may settle as it considers appropriate, until judgments or settlements use up your liability limit.
Your truck is paid at the lower number
Physical damage pays the lesser of actual cash value or repair cost, minus your deductible. If you disagree on the amount, either side can demand appraisal.
State law sets the claim clock
In Texas, an insurer has 15 days to acknowledge your own claim and 15 business days to decide once it has what it asked for. Surplus lines insurers get longer.

How does a semi truck insurance claim work?
It depends on who suffered the loss. Harm your truck causes to others, damage to your own truck, and damage to the freight are separate claims, with different people paid and different rules in control.
| The loss | Who gets paid | Who controls the claim |
|---|---|---|
| Injury or damage your truck causes to others | The injured people, up to your liability limit | Your insurer, which defends and settles |
| Damage to or theft of your own truck | You, and your lender if it is a loss payee | You and your insurer, with appraisal for value disputes |
| Loss of or damage to the freight | The cargo owner, through a claim against you | You, within federal deadlines, with your cargo insurer |
One crash can open all three at once. Which coverage answers which loss is mapped in our guide to types of commercial truck insurance, and freight claims and their deadlines are in documenting damaged cargo. The rest of this guide covers claims against you and claims on your truck.
What do you have to do after reporting a claim?
Everything the policy's conditions ask. The standard business auto form says the insurer has no duty to provide coverage unless there has been full compliance with these duties, so they are not courtesies.
Step 1: Give prompt notice
Tell the insurer or its authorized representative how, when, and where the accident or loss happened, the insured's name and address, and, as far as you can, the names and addresses of injured people and witnesses. What to do at the scene first is in our guide to truck accident procedures.
Step 2: Don't pay, promise, or spend
Assume no obligation, make no payment, and incur no expense without the insurer's consent, except at your own cost. Cash handed to the other driver at the scene is yours to lose.
Step 3: Forward every legal paper immediately
Send the insurer copies of any request, demand, order, notice, summons, or legal paper about the claim right away. Name one person in your office who receives them and forwards them the same day.
Step 4: Cooperate with the investigation
Cooperate in the investigation, settlement, or defense. Authorize the insurer to obtain medical records and other information, and submit to medical exams by its physicians, at its expense, as often as it reasonably requires.
Step 5: Protect the truck and keep receipts
For damage to your own truck, report a theft to police promptly, take reasonable steps to protect the truck from further damage, and keep a record of those expenses. Let the insurer inspect the truck and your records before you repair or dispose of it, and give a signed statement or an examination under oath if asked.
One condition overrides the rest. The form is void in any case of fraud by you, and void if you or another insured intentionally conceal or misrepresent a material fact about a claim.
Who controls a liability claim against you?
Your insurer does. Under the standard form, it has the right and duty to defend you against a suit for covered injury or damage, and it may investigate and settle any claim or suit as it considers appropriate.
That control ends at your limit. The duty to defend or settle ends once judgments or settlements have used up your liability limit, and anything above it is yours. Set your limit for what you haul and where you run, not only for the federal minimum.
What the insurer pays on top of the limit
The standard form adds supplementary payments that do not reduce your limit:
- All expenses the insurer incurs.
- Up to $2,000 for bail bonds required because of a covered accident, including related traffic violations. The insurer does not have to furnish the bonds.
- Reasonable expenses you incur at its request, including actual lost earnings up to $250 a day.
- Court costs taxed against you in a suit it defends, but not attorneys' fees taxed against you.
- Interest on the full judgment that accrues after it is entered, until the insurer pays or offers the part within its limit.
When a letter says "reservation of rights"
It means the insurer is investigating, or even defending, while keeping its right to deny coverage later. As IRMI explains, the letter also warns you that part of the claim may not be covered, so you can protect your uninsured interests. Read it the day it arrives and ask which facts the insurer is questioning.
When only the MCS-90 pays
If a claim would not be covered except for the MCS-90 endorsement, the insurer pays the injured party and then has the right to seek reimbursement from you. How an unlisted truck ends up there is in our guide to commercial auto symbols.
How is a physical damage claim on your truck settled?
At the insurer's option. The standard form lets it pay for the loss, repair or replace the truck, return stolen property and pay for damage from the theft, or take the truck at an agreed or appraised value.
- The most it pays: the lesser of actual cash value at the time of loss or the cost to repair or replace with property of like kind and quality. On a total loss, it adjusts for depreciation and condition.
- Deductible: applied to each covered truck. A comprehensive deductible does not apply to a loss caused by fire or lightning.
- Sales tax: included when the insurer pays for the loss.
- Betterment: if a repair leaves the truck better than like kind and quality, the insurer does not pay for the improvement.
- Your lender: a lender named as loss payee is entitled to its share of the proceeds.
An older tractor can settle well below what you still owe on it. Our physical damage coverage page explains the options we place for tractors and trailers.
If you disagree on the amount: appraisal
Either side can demand appraisal when you disagree on the amount of loss. Each picks a competent appraiser, the two choose an impartial umpire, and a decision agreed by any two is binding. You pay your own appraiser and split the umpire and other costs equally.
Appraisal settles the amount, not the coverage: the insurer keeps its right to deny the claim.
If another driver caused it
Once your insurer pays, your right to recover from the at-fault driver transfers to it, which is called subrogation. You must do what is needed to secure those rights and nothing after the loss to impair them, so don't sign a release with the other driver or their insurer without checking with yours.
What can you do if a claim stalls or is denied?
Ask for the reason in writing, then take it to your state's insurance department. State law sets the claim-handling standards, and the NAIC's model Unfair Claims Settlement Practices Act shows the conduct regulators target when an insurer does it flagrantly or as a general business practice:
- Failing to acknowledge claim communications with reasonable promptness
- Refusing to pay without a reasonable investigation
- Not attempting in good faith a prompt, fair settlement once liability is reasonably clear
- Failing to affirm or deny coverage within a reasonable time after investigating
- Not promptly explaining a denial or a compromise offer
- Forcing insureds to sue by offering substantially less than they later recover
The model act does not give you a right to sue on its own; it is enforced by the regulator.
Example: Texas deadlines for your own claims
Texas puts numbers on first-party claims, the ones paid directly to you, such as damage to your own truck. They do not apply to a claim someone else makes against your liability coverage.
| What the insurer must do | Most insurers | Eligible surplus lines insurers |
|---|---|---|
| Acknowledge the claim, start investigating, and request what it needs, after notice | 15 days | 30 business days |
| Accept or reject in writing, after receiving everything it asked for | 15 business days, or within 45 days of telling you why it needs more time | Same |
| Pay, after accepting | 5 business days | 20 business days |
A rejection must state its reasons. An insurer that is liable for the claim and misses these rules owes interest on the claim as damages, plus reasonable attorney's fees. Texas policyholders can file complaints against insurers, agents, and adjusters with the Texas Department of Insurance.
How does a claim follow you to renewal?
Through your loss runs, the claim reports insurers provide to their insureds, and, for a recordable crash, through FMCSA's crash record. Ask for your loss runs before you renew or shop, and check that each claim is listed correctly and closed claims show as closed.
What underwriters do with your crash and inspection history is in our guide to how CSA scores affect truck insurance.
If an insurer decides to cancel the policy behind your federal filing, 49 CFR 387.7 requires 35 days' written notice, counted from when the notice is transmitted. Use that time to place replacement coverage so your filing never lapses.
