Physical damage truck insurance in California for commercial fleets

Physical damage is the half of a business auto policy that generally protects your own vehicles rather than other people. It's usually bought in two parts, each with its own deductible, and you can often choose them vehicle by vehicle: A new financed box truck might carry both, while a paid-off, high-mileage pickup carries neither.

• Wear and tear, rust, mechanical or electrical breakdown and freezing.
• Tire damage on its own, unless it's part of a larger covered loss such as a theft or fire.
• Tools, inventory and customers' goods inside the vehicle.
• Electronics that aren't permanently installed and some installed equipment unless it's declared.
• Damage to other people's vehicles, which is liability's job.
• Rentals and borrowed vehicles, unless you add hired auto physical damage.

Unless you choose otherwise, physical damage typically pays actual cash value (ACV): what the truck was worth just before the loss, accounting for age, mileage and condition. For a common pickup with plenty of sales data, ACV tends to be easy to establish and fair.

Trucks with expensive bodies and upfits are harder. A service body with a crane, a box truck with a liftgate and refrigeration or a bucket truck with an insulated boom can be worth far more than the chassis's book value suggests. Stated amount coverage lets you put a value on the declarations page for each unit, so the carrier can see and rate the whole truck. On most forms, that number is a ceiling, not a promise: The carrier pays the least of the stated amount, ACV or the cost to repair. Set it too low, and a total loss may pay only that figure; inflate it, and you pay premium for value you likely can't collect. Either way, keep the upfit invoices that help prove what the body is worth.

The trade-offs are laid out side by side in how a total-loss truck gets valued.

Financed and leased trucks add a lender. The lender will usually require comprehensive and collision, set a maximum deductible and be named as loss payee, so a claim check typically goes to both of you. Some carriers offer loan or lease gap coverage for the difference between ACV and what you still owe.

Comprehensive is usually the coverage that responds to California's big events. The Department of Insurance's 2025 consumer alert reminds drivers that comprehensive auto coverage typically pays for flood damage and that a flood or mudslide exclusion may not apply when the loss follows a recent wildfire. After the Los Angeles fires, the Department counted 5,597 auto claims as of February 5, 2025; by November 17, 2025, its wildfire claims tracker showed 42,121 claims across all lines of insurance, with $22.4 billion paid.

Theft is the steadier risk. The CHP counted 7,331 trailers stolen in California in 2025, and 80.0% of stolen commercial trucks were recovered, against 84.0% of all stolen vehicles. A recovered truck is often stripped or damaged, and one that's never found is usually treated as a total loss valued under your policy's terms.

Yard security, GPS trackers and hitch locks on parked trailers can all help, and underwriters often ask about them at each garaging address.

Plumbing

A jetter truck carries a high-pressure jetting unit, a water tank and hose reels that can be worth more than the chassis. If that equipment is permanently mounted, build it into the vehicle's value; see plumbing contractor commercial auto insurance.

Electrical and tree service

A bucket truck's boom and insulated platform make up much of its value, and a rollover or a boom strike can be a near-total loss. These units are often prime candidates for stated values; bucket truck insurance gets its own page for that reason.

Landscaping

Trailers parked overnight at a yard or a curb are easy to hitch and drive away. Each one usually needs its own physical damage line, and the mower on it is generally equipment, not auto; more on landscape truck insurance in California.

Wholesale distributors

Box trucks with liftgates and refrigeration units often pick up damage in docks and alleys: a post clipped while backing, a liftgate bent against a curb. Collision typically handles those; see box truck insurance for distributors and box truck insurance quote.

Roofing

Roofing flatbeds and conveyor trucks carry costly loading equipment, and a truck parked under trees or near a fire-prone hillside is exposed to comprehensive losses. List conveyors and loaders with the truck; see roofing contractor commercial auto insurance.
