Semi truck physical damage insurance: covering the truck itself
Semi truck physical damage insurance pays to repair or replace your own tractor, and trailer if you insure it, after a collision or other damage such as fire, theft or weather. No law requires it, but your lender or lessor usually does, and if you are leased onto a carrier, the carrier's policy does not cover your truck.
Contents
The short version
- Two parts: collision (hitting something or rolling over) and comprehensive (most other causes).
- The truck is insured for a value you declare; set it to the truck's real current value, equipment included.
- The deductible is what you pay per claim; raising it lowers the premium.
- Trailers you pull under an interchange agreement need separate coverage.
What does physical damage insurance cover on a semi?
Progressive describes physical damage as "a general term for a group of insurance coverages that protect your vehicle". On a truck policy, it is usually two coverages, which you can often buy separately.
| Collision | Comprehensive | |
|---|---|---|
| Pays when | The truck collides with another vehicle or object, or overturns | The truck is damaged by something other than collision or overturn |
| Typical examples | Rear-ending a car, hitting a dock or a pole, a rollover on a ramp | Theft, fire, hail, flood, vandalism |
| Fault | Pays whoever caused the accident (minus your deductible) | No other driver involved in most cases |
Triple-I calls comprehensive "the broadest form of auto physical damage coverage", because it covers losses "from any cause except collision and overturn" (Triple-I, business vehicle insurance). Where a given event falls (an animal strike, falling objects, glass) depends on your policy's definitions.
Some insurers offer narrower or packaged versions. Progressive, for example, sells "Fire and Theft with CAC" as an alternative to comprehensive, notes that it does not cover windshield claims, and requires either comprehensive or Fire and Theft with CAC before it will add collision.
What physical damage does not cover
- Other people's vehicles and property: that is trucking liability.
- The freight: that is motor truck cargo.
- Non-owned trailers pulled under an interchange agreement: Progressive says its physical damage "cannot be applied to non-owned trailers".
- Wear, maintenance and mechanical breakdown, which are not sudden accidental damage.
Who requires physical damage coverage?
Not the law
The federal minimums in 49 CFR part 387 are about protecting the public, so they set liability amounts only. Progressive says that if your vehicle is fully paid for, physical damage "is optional".
Your lender or lessor
If you financed or leased the truck, the contract with the lender or lessor is what makes physical damage mandatory. Progressive says that if your vehicle is leased, "you probably are required" to carry it. The contract can also require that the lender be named on the policy as loss payee, so that a total-loss payment goes to it up to what you owe; insurers offer loss payee and lessor additional insured endorsements for this. Your financing contract states the conditions, which may include a maximum deductible.
The carrier you lease onto: not your insurer for the truck
Being leased onto a carrier does not insure your truck. As Progressive explains on its non-trucking liability page, carriers that provide primary liability for owner-operators "don't include" physical damage, and that gap "still exists, even if you get non-trucking liability insurance". If the carrier offers to provide it and charge you for it, 49 CFR 376.12(j) requires the lease to state the amount charged back and, on request, give you a certificate showing coverage, cost and deductible. Our page on leased owner-operator insurance covers those clauses.
Stated value: how much is your truck insured for?
Truck physical damage is usually written for an amount you declare when you buy the policy. Progressive calls it the "stated amount", "your best estimate of the current value of your vehicle", and says it should take into account the truck's age and condition "as well as any permanently attached equipment" (Progressive, physical damage). HUB International lists tractor physical damage as written at "stated value or actual cash value".
The settlement rules behind those words are set by each policy, and they matter most on a total loss. Ask the insurer in writing:
- On a total loss, do you pay the stated amount, or the lower of the stated amount and the truck's actual cash value?
- Is equipment such as an APU, a sleeper upgrade or a headache rack included in the value, or does it need to be listed?
- Are tarps, chains and binders covered, and should they count in the stated value?
Declaring more than the truck is worth raises the premium without guaranteeing a bigger payout, depending on how the policy settles. Declaring less lowers the premium but caps what you can recover. Review the stated value every renewal: trucks lose value, and equipment gets added.
Choosing a deductible
The deductible is the amount you agree to pay out of pocket on each claim, and Progressive notes that a higher deductible is "an easy way to lower the price". With one truck, the right level is the one you could pay quickly without losing the truck's earnings for weeks: a deductible you cannot afford turns a covered claim into an unpaid repair.
Points to compare between quotes:
- separate deductibles for collision and comprehensive, or one for both;
- whether a single deductible applies when the same accident damages truck and cargo (some insurers offer this);
- any maximum deductible your lender allows.
Other ways to bring the premium down, and the ones that backfire, are covered in cheap truck insurance.
A worked example
Illustration with round numbers, not a quote. A tractor is insured at a stated amount of $90,000 with a $2,500 collision deductible.
- Partial loss: after a collision, the covered repair is $20,000. The policy pays $17,500; the owner pays the $2,500 deductible.
- Total loss: the policy pays at most the stated amount minus the deductible, here $87,500, under the policy's settlement terms. If $95,000 is still owed on the truck loan, about $7,500 of the loan remains to be paid without a truck. Ask your agent whether any option on your policy addresses a loan balance above the truck's value.
The same truck stopped for repairs also stops earning. Some insurers offer downtime or rental reimbursement options; Progressive, for example, lists a "Rental Reimbursement with Downtime" coverage. Read the daily amount and the waiting period before counting on it.
Trailers and add-ons
An owned trailer can be listed for physical damage on your policy with its own stated value. A trailer you pull for someone else under a written interchange agreement needs trailer interchange coverage, and a non-owned trailer outside such an agreement may need another option: see tractor-trailer insurance. Some insurers include towing after a covered loss automatically; check whether yours does.
Checklist before you buy
- Check the lender's conditions. Loss payee wording and maximum deductible from your financing or lease contract.
- Set a realistic value. Current market value plus permanently attached equipment, not the purchase price.
- Ask how a total loss is settled and get the answer in writing.
- Pick deductibles you can pay and compare collision and comprehensive separately.
- List every trailer you own, and get interchange cover before pulling someone else's.
Physical damage is one line among several; see how it fits with the others in trucking insurance coverages, or let the coverage planner tell you whether your situation calls for it.

FAQ
Is physical damage insurance required by law for a semi?
No federal or state rule we know of requires it: the federal financial responsibility rules in 49 CFR part 387 cover liability to the public, not your own truck. The requirement comes from whoever finances or leases the truck to you. Progressive says physical damage is optional if the truck is fully paid for.
Does physical damage cover my truck when someone else causes the crash?
Your collision coverage can pay for repairs, minus your deductible, whoever is at fault. You can also claim against the at-fault driver's liability insurer instead; when your own insurer pays, it may then pursue the other party. Ask your insurer how it handles deductibles in that case.
Can I drop physical damage once the truck is paid off?
You can, since no lender is requiring it anymore. Before you do, compare the yearly premium with what it would cost you to repair or replace the truck from savings, and how long you could go without income while you do it.
Does physical damage cover mechanical breakdown?
Generally no. Collision and comprehensive cover sudden damage from a crash or from causes such as fire, theft or weather. Wear and mechanical failure are treated as maintenance costs. Check the exclusions section of your policy.
