Physical damage vs. auto liability insurance
One protects your equipment. The other protects against claims made against you.
These two coverages are often discussed together because both attach to the vehicle, but they answer entirely different questions and are triggered by entirely different events.
Confusing the two is one of the more expensive misunderstandings in commercial trucking insurance.
Physical damage: your truck
Physical damage insurance is designed to respond to covered physical loss or damage to your own covered trucks and equipment, from causes such as collision, theft or vandalism, depending on the policy.
Auto liability: the other party
Auto liability responds to covered claims where the insured is legally responsible for bodily injury or property damage arising from a covered auto operation. It is about the harm your operation may cause to others.
Different levers, different decisions
Physical damage decisions turn on valuation and deductibles. Liability decisions turn on limits, and those limits are frequently set by authority, contracts and regulation rather than by preference.
Why you usually need both
Carrying only liability leaves your own equipment exposed. Carrying only physical damage leaves the business exposed to third-party claims and, in most commercial operations, out of step with regulatory and contractual requirements.
The right structure depends on the equipment, the operation and the obligations the business has taken on.
