Physical Damage Insurance
for Commercial Trucks
& Fleets.

Your commercial auto liability covers what happens to others when you’re in an accident. Physical damage is what covers your truck — the asset you depend on to generate revenue. If your truck is damaged, destroyed, or stolen and you don’t have physical damage coverage, that loss comes entirely out of your operation.

What Physical Damage Insurance Covers

Coverage for your own truck, trailer, and equipment — when they’re damaged, destroyed, or stolen.

Physical damage insurance covers the cost to repair or replace your commercial vehicle — your truck, tractor, trailer, or other equipment — when it is damaged or destroyed. It is first-party coverage: it protects your own property, not your liability to others. Commercial auto liability covers the other party in an accident; physical damage covers your vehicle in that same accident.

Physical damage consists of two components: collision coverage and comprehensive coverage. Collision pays for damage resulting from an impact — an accident, a rollover, hitting an object. Comprehensive pays for damage from causes other than collision — fire, theft, vandalism, hail, flood, and other covered non-collision events. Both can be purchased together or separately, depending on the vehicle’s value and the owner’s risk tolerance.

For owner-operators and small fleets, physical damage is often the most financially significant coverage in the program. A semi-truck can represent $100,000–$200,000 or more in asset value. Losing that asset to an accident, fire, or theft without physical damage coverage is a business-ending event for most operations.

“Liability tells someone else you’ll cover their losses if you cause an accident. Physical damage tells you that your truck will be repaired or replaced. One protects others from you. The other protects your business from a loss you can’t absorb.”

Physical damage is typically required by lenders when a commercial vehicle is financed — the lender has a financial interest in the vehicle and requires that interest to be insured. For paid-off equipment, it becomes a business decision about whether the vehicle’s value justifies the premium versus self-insuring the physical damage risk.


What physical damage covers:

Collision damage
Damage to your vehicle from an impact — hitting another vehicle, an object, or rolling over — regardless of fault
Fire damage
Vehicle damage or total loss from fire — engine fires, electrical fires, and fires caused by external sources while parked or in transit
Theft
Loss of the vehicle or tractor due to theft — covered under comprehensive physical damage at the vehicle’s insured value
Hail, wind & weather
Physical damage from hail, wind, flooding, and other weather events — particularly relevant in Texas where severe weather is frequent
Vandalism
Physical damage from vandalism while parked — broken glass, slashed tires, body damage, and other intentional damage
Owned trailers
Physical damage to owned trailers scheduled on the policy — flatbeds, reefers, dry vans, and other trailer types your business owns

Collision vs. Comprehensive — Understanding Both Components

Physical damage has two distinct parts. Most carriers need both — but the decision depends on your vehicle value and operation.

Physical damage isn’t a single coverage — it’s two components that address different types of loss. Understanding what each one covers helps you make an informed decision about which combination is right for your fleet.

Collision Coverage

Pays for damage from an impact — regardless of fault

Collision covers physical damage to your vehicle resulting from a collision with another vehicle, an object, or a rollover. It doesn’t matter who caused the accident — collision pays for your vehicle regardless of fault. If another driver hits you and doesn’t have adequate coverage, collision ensures your truck gets repaired even while the liability claim is sorted out.

  • Accident with another vehicle — at fault or not at fault

  • Single-vehicle accident — rollover, hitting a guardrail, leaving the road

  • Hitting a fixed object — a building, a pole, a loading dock

  • Backing accidents — one of the most common trucking loss events

  • Underride and override accidents with other vehicles

Comprehensive Coverage

Pays for damage from causes other than collision

Comprehensive covers physical damage to your vehicle from virtually any cause that isn’t a collision — fire, theft, vandalism, weather, flood, and other non-impact events. For trucking operations, theft of the tractor and fire are the most significant comprehensive exposures — and both can result in a total loss of a high-value asset in a single event.

  • Fire — engine fires, electrical fires, external fire sources

  • Theft of the tractor or trailer

  • Hail and wind damage — significant in Texas

  • Flood damage — particularly relevant in South and East Texas

  • Vandalism while parked — broken glass, body damage, tire slashing

Most carriers need both. Collision-only leaves you exposed to fire, theft, and weather. Comprehensive-only leaves you without coverage for the most common event — an accident. Together they provide complete physical damage protection for your vehicle investment.

Liability vs. Physical Damage — Two Coverages, Two Directions

Liability protects others from your truck. Physical damage protects your truck from the world.

These two coverages work in opposite directions. Understanding which one pays for what — in the same accident — is fundamental to building a complete commercial auto program.

Commercial Auto Liability

Covers damage and injuries your truck causes to others

Commercial auto liability pays for bodily injury and property damage your vehicle causes to other people in an accident. It covers the other driver’s injuries, their vehicle damage, and your legal defense. It does not cover any damage to your own truck — that’s entirely separate.

Example: Your truck rear-ends a passenger car on the highway. Liability covers the other driver’s injuries, their vehicle damage, and your legal defense. Your truck’s damage is covered by your physical damage policy — not liability.
Physical Damage Coverage

Covers damage to your own truck — from any covered cause

Physical damage pays to repair or replace your own vehicle when it is damaged or destroyed. It covers your truck in an accident regardless of fault, and covers non-collision losses like fire, theft, and weather. It has no coverage for third-party claims — that’s liability’s job.

Example: In the same accident, your truck sustains $35,000 in front-end damage. Physical damage pays to repair your truck after your deductible. If your truck is totaled, physical damage pays the actual cash value or agreed value up to the policy limit.

The complete program: Liability is legally required to operate. Physical damage protects the asset that generates the revenue. Most serious operations carry both — one without the other leaves either the public or the truck unprotected.

Key Coverage Decisions

The details that determine how much your physical damage policy actually pays — and when.

Physical damage involves several important coverage decisions that significantly affect what the policy pays and what comes out of your pocket. We walk through each one when building your physical damage program.

Stated Value vs. Actual Cash Value

Actual cash value (ACV) pays the depreciated market value of the vehicle at the time of loss — what it was worth right before the accident, not what you paid for it. Stated value policies pay up to the stated amount but typically only the ACV if lower. Agreed value policies pay the full agreed amount with no depreciation deduction. For newer or high-value trucks, understanding which valuation method your policy uses is critical — the gap between what ACV pays and what a new equivalent costs can be tens of thousands of dollars.

Deductible

Physical damage policies have a per-occurrence deductible — the amount you pay out of pocket before the policy responds. Higher deductibles mean lower premiums; lower deductibles mean more coverage but higher cost. For trucking operations, deductibles commonly run from $1,000 to $5,000 or higher. The right deductible balances premium savings against what you can realistically absorb from a single incident. Some fleets use higher deductibles on older, lower-value equipment and lower deductibles on newer, high-value units.

Gap Coverage

When a financed truck is totaled, the insurance payout may be less than the outstanding loan balance — especially early in the loan when depreciation has reduced the vehicle’s ACV faster than the loan has been paid down. Gap coverage pays the difference between what physical damage pays and what you still owe the lender. For carriers financing newer or high-cost equipment, gap coverage prevents a total loss from leaving you with a destroyed truck and a remaining loan balance simultaneously.

Rental Reimbursement

When your truck is in the shop for a covered repair, your operation is down. Rental reimbursement pays for a rental vehicle or the cost of leasing substitute equipment while your truck is being repaired. For owner-operators and small fleets where every truck is essential to revenue, rental reimbursement reduces the business income impact of a physical damage claim while the repair is completed.

Rental Reimbursement

When your truck is in the shop for a covered repair, your operation is down. Rental reimbursement pays for a rental vehicle or the cost of leasing substitute equipment while your truck is being repaired. For owner-operators and small fleets where every truck is essential to revenue, rental reimbursement reduces the business income impact of a physical damage claim while the repair is completed.

Coverage on Older Equipment

As trucks age and depreciate, the ACV decreases — and at some point the physical damage premium may not be justified relative to the payout potential. A truck worth $15,000 with a $3,000 premium and a $5,000 deductible nets only $10,000 in the worst case — a calculation worth making. For older, paid-off equipment, some operators choose to self-insure the physical damage risk and carry liability only. We help clients think through when that trade-off makes sense.

Who Needs Physical Damage Coverage

Any commercial vehicle operator whose truck represents a financial asset they can’t afford to lose.

Physical damage is especially critical when the vehicle is financed, when it’s newer or high-value, or when the operation depends on that specific vehicle to generate revenue.

Owner-Operators

For a single-truck operator, the tractor is the entire business. A total loss without physical damage coverage ends the operation. For most owner-operators, physical damage is non-negotiable regardless of truck age or value.

Small Fleets

Each truck in a small fleet represents a meaningful percentage of total revenue capacity. Losing even one vehicle to damage or theft without coverage creates immediate financial strain on the entire operation.

Financed Equipment

Lenders require physical damage coverage on financed vehicles as a loan condition. A carrier who lets physical damage lapse on a financed truck risks forced-placed insurance from the lender — typically at a much higher rate and with limited coverage.

High-Value Specialized Equipment

Specialty trailers, reefers, flatbeds with specialized configurations, and other high-value non-standard equipment carry physical damage exposure that justifies dedicated coverage regardless of fleet size.

New or Newer Trucks

A newer truck depreciates rapidly in the first few years. ACV on a two-year-old semi may still represent $80,000–$120,000 in value — significant enough to justify the physical damage premium with clear financial logic.

Carriers in High-Risk Lanes

Carriers operating in lanes with high accident frequency, significant weather exposure, or elevated theft risk have above-average physical damage exposure that coverage directly addresses.

Contractors with Commercial Vehicles

Construction, landscaping, and service businesses with commercial trucks and vans benefit from physical damage on their fleet — especially for newer, financed, or high-value vehicles used for job site and service operations.

Any Commercial Vehicle with Loan Balance

If you owe money on a commercial vehicle, your lender requires physical damage coverage. Full stop. The question for paid-off vehicles is whether the remaining value justifies the premium — a conversation we’re happy to have.

Real Scenarios.

Physical damage losses — what they cost without coverage and what the policy pays with it.

01
A semi-truck is totaled in a highway accident
An owner-operator is involved in a serious highway collision. The tractor is declared a total loss — the frame is bent and the repair estimate exceeds the vehicle’s value. Physical damage pays the ACV of the truck minus the deductible. For a $120,000 truck with a $2,500 deductible, the payout is $117,500 — enough to replace the equipment and keep the operation running. Without physical damage, the driver loses their truck and their income source in a single event.

03
A tractor is stolen from a terminal overnight
A carrier’s tractor is stolen from a secured terminal during an overnight layover. Comprehensive physical damage covers theft of the vehicle. The carrier receives the ACV of the stolen tractor after the deductible. Without comprehensive coverage, the stolen truck is an uninsured total loss — the operator owes the remaining loan balance on a truck they no longer have, while also needing to replace the vehicle to keep hauling.

05
A backing accident damages a reefer trailer
A driver backs a reefer trailer into a loading dock too aggressively and damages the rear doors and frame. Backing accidents are among the most frequent physical damage claims in trucking — and they’re covered under collision physical damage as an impact event. The trailer repair — which can run $5,000–$15,000 depending on severity — is paid by the policy after the deductible. Without physical damage on the trailer, the carrier pays the repair out of pocket.

02
A truck is destroyed in a cab fire
An engine fire — caused by a fuel line failure — destroys the cab and engine of a Class 8 tractor while the driver is at a rest area. The fire is not from a collision. Comprehensive physical damage covers fire as a covered cause of loss — the policy pays the ACV of the destroyed tractor. Collision-only coverage would not respond to a fire loss. For trucking operations, comprehensive is essential specifically because fire is one of the most total and most common non-collision losses in the industry.

04
A hail storm damages an entire fleet overnight
A severe hail storm passes through a carrier’s terminal lot overnight and damages multiple tractors and trailers — cracked windshields, dented hoods, damaged fairings. Comprehensive physical damage covers hail damage across the fleet. For a small fleet of 5–10 trucks, a single hail event can generate $50,000–$150,000 in total repair costs. Comprehensive coverage on the fleet addresses the full scope of a weather event rather than leaving the carrier to absorb multiple vehicle repairs simultaneously.

06
A carrier totals a financed truck and has a loan gap
A carrier with a $90,000 loan balance totals a truck whose ACV at the time of the loss is $75,000. Without gap coverage, the physical damage policy pays $75,000 and the carrier still owes $15,000 on a destroyed truck while also needing to replace the vehicle. Gap coverage pays the $15,000 difference — eliminating the loan obligation on the totaled truck and allowing the carrier to focus entirely on replacement rather than carrying debt on equipment they no longer have.

Why Get Your Physical Damage Coverage Through McKnight

Physical damage valuation, deductible structure, and fleet-level decisions require more than a standard quote.

Physical damage for commercial vehicles isn’t one decision — it’s several. Valuation method, deductible level, whether to carry collision, comprehensive, or both on each unit, gap coverage on financed equipment, rental reimbursement, and downtime coverage all interact to determine what the policy actually pays when a loss happens. We walk through each decision specifically rather than defaulting to standard settings that may not match your operation.

For fleets, we also help carriers think through coverage differentiation across vehicles — higher limits and lower deductibles on newer, higher-value units; higher deductibles or liability-only on older, paid-off equipment that doesn’t justify the physical damage premium. The right approach isn’t the same for every truck in a mixed-age fleet.

As an independent agency writing trucking programs through carriers that specialize in commercial transportation, we find physical damage markets that understand heavy truck values, specialty equipment, and the specific exposure profile of your operation rather than treating a semi-truck like a delivery van.

Valuation method reviewed specifically
ACV, stated value, agreed value — we confirm how your policy values your equipment before a loss reveals a gap in the payout.

Deductible and coverage structure matched to fleet
We build the right coverage structure for each unit in your fleet — not one standard approach applied to every truck.

Trucking-specific carriers
We place physical damage through carriers that understand heavy truck values and specialty equipment — not general commercial markets.

FAQ

Physical damage questions we hear all the time.

What is physical damage insurance and what does it cover?
Physical damage insurance covers the cost to repair or replace your own commercial vehicle when it is damaged or destroyed. It has two components: collision covers damage from impacts — accidents, rollovers, hitting objects; comprehensive covers damage from non-collision causes — fire, theft, hail, vandalism, and weather. It is first-party coverage that protects your own equipment. Commercial auto liability, by contrast, is third-party coverage that protects others from your truck. Both are necessary for a complete commercial auto program.
Is physical damage required by law for commercial trucks?
Physical damage is not required by law the way commercial auto liability is. Liability is legally required to operate a commercial vehicle. Physical damage is a business decision — with one significant exception: if your vehicle is financed, your lender requires physical damage coverage as a loan condition. Carriers who let physical damage lapse on a financed truck risk the lender placing force-placed insurance on the vehicle, typically at a significantly higher rate and with more limited coverage terms.
What’s the difference between actual cash value and agreed value?
Actual cash value (ACV) pays the depreciated market value of your vehicle at the time of the loss — what it was worth right before the damage, accounting for age and wear. Agreed value policies pay the full amount agreed upon when the policy was placed, with no depreciation deduction. For newer or high-value trucks, agreed value coverage eliminates the gap between ACV and replacement cost. For older equipment, ACV may closely approximate what you’d receive anyway. Understanding which valuation method your policy uses before a total loss prevents a significant and unpleasant surprise at claim time.
What is gap coverage and when do I need it?
Gap coverage pays the difference between what your physical damage policy pays on a total loss and the remaining balance on your vehicle loan. When a truck depreciates faster than the loan is paid down — common in the early years of financing — the ACV payout from physical damage may be less than what you still owe the lender. Gap coverage prevents a total loss from leaving you with a destroyed truck, a remaining loan balance, and a need to finance a replacement vehicle simultaneously. It’s most important for newer financed equipment where the loan-to-value ratio creates meaningful gap exposure.
Should I carry physical damage on older paid-off trucks?
It depends on the truck’s current value, the premium, and your ability to absorb a total loss. As a truck ages and depreciates, the ACV decreases — and the financial logic of paying physical damage premium to insure a declining asset changes. A truck worth $20,000 with a $3,000 deductible nets $17,000 at most in a total loss. If the annual premium for that coverage is $3,000–$4,000, the math may not justify it for some operators. For others, even an older truck is essential to operations and the cost of replacement without insurance is unacceptable. We help carriers think through this truck by truck.
Does physical damage cover my trailer as well as my tractor?
Physical damage on your commercial auto policy covers owned trailers that are scheduled on the policy. Each trailer needs to be specifically listed with its own value and deductible. Non-owned trailers — those operated under interchange agreements — require trailer interchange coverage, which is a separate policy. If you own trailers and want them covered for physical damage, they need to be scheduled on your commercial auto policy or covered under a separate trailer physical damage policy. We make sure every piece of equipment you own is accounted for when building your program.
What happens if I’m in an accident that wasn’t my fault — does physical damage still apply?
Yes — physical damage collision coverage pays for damage to your truck regardless of fault. You pay your deductible and your policy repairs your vehicle while the fault determination and liability claims are sorted out separately. If the other party is at fault and has adequate liability coverage, your insurer may subrogate — pursuing reimbursement from the at-fault party’s insurer for what they paid on your behalf, including potentially returning your deductible. Without physical damage, an accident where the at-fault driver has insufficient insurance or is uninsured leaves you with a damaged truck and no coverage to repair it.
