Commercial Auto Insurance

What commercial auto insurance covers

Commercial auto insurance (also called business auto insurance) covers vehicles that your business owns, leases or uses for work. A policy is built from several coverages, much like personal auto:

• Liability: pays for injuries and property damage you cause to others in an accident. This is the part states require.
• Collision: pays to repair or replace your vehicle after a crash.
• Comprehensive: covers theft, vandalism, fire, hail, falling objects and animal strikes.
• Medical payments or personal injury protection (PIP): helps pay medical bills for you and your passengers, depending on your state.
• Uninsured / underinsured motorist: protects you when the other driver has little or no insurance.

Example: A plumber rear-ends another car while driving the company van to a job. The other driver's car is damaged and the driver is hurt. Commercial auto pays for the other car's repairs and the driver's medical claim, and collision coverage pays to fix the van.

When personal auto isn't enough

Many personal auto policies exclude or limit coverage when a vehicle is used for business. Signs that you need commercial auto include:

• The vehicle is owned or leased by your business.
• You carry tools, equipment or products regularly, like a handyman, electrician or caterer.
• You deliver goods or transport people for pay, like a delivery driver or food truck owner.
• Employees drive the vehicle.
• The vehicle is a work truck, van or trailer, or has signage.
• A client contract asks for commercial auto limits on your certificate of insurance.

If you are unsure, ask your personal auto insurer how it treats business use, in writing.

Hired and non-owned auto (HNOA)

Many small businesses don't own vehicles, but employees still drive for work. Picking up supplies or visiting clients in a personal car creates risk: if the employee causes a serious accident, the injured party may sue your business. Hired and non-owned auto (HNOA) coverage protects the business from that liability when employees use their own cars, or when you rent vehicles. HNOA is often available as an add-on to a business owner's policy or general liability policy. It does not repair the employee's car; their own auto policy covers that.

What commercial auto doesn't cover

• Tools and equipment in the vehicle. Theft of tools from a van is usually covered by tools and equipment insurance, not auto.
• Employee injuries, which are usually workers' compensation claims, even when they happen in a vehicle.
• Wear and tear, breakdowns and maintenance.
• Cargo you haul for customers, unless you add cargo or motor truck cargo coverage.
• Business activities away from the vehicle, which are covered by general liability.

How much does commercial auto insurance cost?

There is no single typical price for commercial auto. Insureon does not publish a median for it in its 2026 cost data, and costs vary widely between businesses. A single sedan used for client visits and a fleet of box trucks are priced very differently. The main cost factors are:

• Vehicle type and value. Heavier vehicles and expensive vans cost more to insure.
• Use. Hauling heavy equipment, carrying passengers or making many deliveries raises risk.
• Drivers. Ages, experience and driving records matter a lot.
• Location. Urban areas with heavy traffic and higher claim costs usually cost more.
• Miles driven and the radius of operation.
• Limits and deductibles you choose.
• Claims history.

The best way to know your cost is to get quotes for your actual vehicles and drivers. For other policies, see how much does business insurance cost or the business insurance cost calculator.

Limits and deductibles explained

Every state sets a minimum auto liability limit, but those minimums are often low compared with the cost of a serious accident. Many businesses choose a combined single limit (for example $1 million), which applies to bodily injury and property damage together. Client contracts frequently require a specific auto limit on your certificate of insurance. Collision and comprehensive each have a deductible, the amount you pay before the insurer pays for your vehicle's damage. A higher deductible lowers the premium.

How to buy commercial auto insurance

Gather your vehicle details, driver list and records, and a clear description of how the vehicles are used. Get quotes from licensed agents, brokers or insurers that write commercial auto. Make sure every driver is listed, the use is described accurately, and your limits match state rules and contracts. If you also carry tools, ask about pairing auto with tools and equipment coverage.

Business vehicle use: common situations

How to lower commercial auto costs

• Hire careful drivers and check motor vehicle records before letting anyone drive.
• Set a written driving policy that covers phone use, seat belts and who may drive.
• Choose higher deductibles for collision and comprehensive if your budget allows.
• Match the vehicle to the job. A smaller vehicle can cost less to insure when it does the work.
• Keep vehicles maintained and record inspections.
• Use telematics if your insurer offers a discount for monitored driving.
• Review your vehicle list every renewal and remove vehicles you no longer use.

Example: A landscaper adds a second truck and a new driver in spring but forgets to tell the insurer. When the new driver causes an accident, the claim is delayed while the insurer reviews the unlisted vehicle and driver. Updating your policy whenever vehicles or drivers change avoids that problem.
