Physical Damage Coverage for Commercial Trucks: Collision, Comprehensive, and What It Costs in 2026

Physical damage insurance covers your trucks and trailers against loss or damage — from the collision with another vehicle to the hailstorm that destroys six trailers in a Houston yard overnight. It’s the coverage that protects your equipment investment when something goes wrong with your own vehicles, as distinct from the liability coverage that protects you when something goes wrong with other people’s vehicles or property.

Collision vs. Comprehensive: What Each Covers

Collision coverage pays for damage to your truck when it collides with another vehicle or object — regardless of fault. If you rear-end another vehicle, run off the road, or back into a loading dock, collision pays to repair or replace your truck. The at-fault driver’s liability insurance covers the other party’s damages; collision covers your vehicle regardless of who caused the accident.

Comprehensive coverage pays for losses that aren’t collisions: theft, fire, flood, hail, wind, falling objects, and vandalism. For Houston operators, comprehensive is particularly important — Gulf Coast hurricanes, severe hail events in the DFW corridor, and vehicle theft from unattended yards are all comprehensive perils. A single hailstorm can generate comprehensive claims on every trailer in an exposed yard.

Agreed Value vs. Actual Cash Value

Policies settle physical damage claims on either an agreed value or actual cash value (ACV) basis. ACV applies depreciation — as your truck ages, the policy pays progressively less for a total loss. A semi worth $150,000 when purchased might be valued at $90,000 three years later under ACV. An agreed value policy states a specific value upfront and pays that amount on a total loss regardless of depreciation. Agreed value costs slightly more but eliminates the settlement dispute about what your truck is worth after a loss.

For newer equipment or high-specification trucks, agreed value is worth the additional premium. For older units with residual values below $40,000, ACV is often adequate.

When to Self-Insure Physical Damage

Large fleets with owned-free-and-clear equipment — no outstanding liens — can choose to retain physical damage risk rather than insure it. The economics: if you’re paying $4,500/year per unit for physical damage on 60 trucks ($270,000 annually), and your average physical damage claim runs $18,000, you need to have more than 15 claims per year to justify insuring it. Many established fleets with maintained, medium-aged equipment retain physical damage entirely and self-fund repairs from operating cash flow.

The threshold for considering self-insurance is typically 30+ trucks with equipment valued below $80,000 per unit. Higher-value fleets, those with high-spec refrigerated trailers, or those in high-theft markets should insure regardless of fleet size.
