Illinois auto repair shops handle a wide range of vehicle traffic, from Chicago's dense urban core to suburban dealerships and rural independent shops downstate. What stays constant across all of them is the commercial auto exposure that comes with operating a repair business. Test driving customer vehicles, running a tow truck, keeping loaner cars available for customers, sending drivers to pick up parts: each activity creates liability the moment a vehicle hits the street. Garage liability and garage keeper's liability cover what happens inside your shop. Commercial auto covers what happens when your vehicles or your drivers are out in traffic.

What Commercial Auto Insurance Covers for Illinois Auto Repair Shops

Test Driving Customer Vehicles

After completing a repair, a technician taking the car for a test drive is a standard quality check. But it also puts your shop on the hook for any accident that technician causes while behind the wheel. Illinois law holds operators of vehicles liable for negligent driving, and your shop is responsible for its employees' actions in the course of employment. A third-party claim arising from a test drive, covering bodily injury or property damage to others, is a commercial auto claim. The specific coverage mechanism depends on whether your policy includes non-owned auto provisions or whether you rely on a garage policy endorsement. Either way, confirm with your agent that test drives are covered.

Shop-Owned Service Vehicles

Illinois requires all registered vehicles to carry minimum liability insurance. For vehicles titled to your business, that means a commercial auto policy. This includes any vehicle regularly used for shop operations: parts pickups, deliveries, management vehicles, mobile service vans, and courtesy cars. Business use on a personal auto policy is typically excluded, so business-owned vehicles need to be on a commercial auto policy.

Tow Trucks

If your shop operates tow trucks as part of its service, those vehicles need commercial auto coverage with appropriate vehicle classification. Tow trucks are rated separately from passenger vehicles and service trucks because of their higher weight class, on-hook exposure, and operational complexity. On-hook coverage, which protects the vehicle being towed, is typically a separate endorsement. Illinois tow operators are subject to state licensing requirements, and some municipalities have additional requirements in Chicago.

Parts Runs and Delivery Vehicles

A driver picking up a part from a NAPA down the street or delivering a finished vehicle to a customer is making a business trip. Personal auto insurance does not cover business use. If your shop uses any vehicle for regular business errands or customer deliveries, it needs to be on your commercial auto policy.

Employee-Driven Shop Vehicles

Illinois employers are vicariously liable for employee conduct during the scope of employment. When an employee drives a shop vehicle and causes an accident, your commercial auto policy covers the liability. A hired and non-owned auto endorsement extends coverage to employees using their own vehicles for shop business.

What Commercial Auto Insurance Does NOT Cover

Customer Vehicles at Rest in Your Shop

Damage to a customer's car while it is parked on your lot or sitting in a service bay is a garage keeper's liability claim. Commercial auto only covers vehicles in operation.

Tools and Shop Equipment in Vehicles

Commercial auto covers the vehicle and liability from driving it. Tools, parts, and inventory in shop vehicles need inland marine or commercial property coverage.

Employee Injuries from Accidents

Workers compensation is the coverage that handles employee injuries. Illinois requires most employers to carry workers comp. Auto repair shop employees face physical injury risk from vehicle-related activities, so workers comp is a practical necessity beyond the legal requirement.

Vehicles You Are Currently Repairing

Vehicles in your care for service or repair are covered by garage keeper's liability, not commercial auto.

Illinois-Specific Considerations

Illinois requires minimum auto liability limits of $25,000 per person and $50,000 per accident for bodily injury, and $20,000 for property damage. These minimums apply to all registered vehicles, including commercial vehicles. For an auto repair shop, especially one operating a tow truck or loaner vehicles, the state minimums are a starting point, not a recommended coverage level. Most shops carry at least $500,000 combined single limit. Shops with multiple vehicles or tow trucks should consider $1M.

Illinois is a fault state for auto accidents. This means the at-fault driver's insurance pays for the other party's damages. Illinois also uses comparative negligence, so damages can be reduced proportionally based on each party's share of fault. If one of your drivers is partially at fault in an accident, the liability allocated to your shop comes out of your commercial auto policy.

Chicago and the surrounding Cook County area generate much higher commercial auto premiums than the rest of Illinois. Traffic density, higher accident frequency, and elevated repair and litigation costs all contribute. A shop in Chicago may pay 40 to 60 percent more than a similar shop in Springfield or Peoria.

Illinois does not mandate uninsured motorist coverage on commercial auto policies, but it is available and recommended. Illinois has a meaningful percentage of uninsured drivers, and if one of your shop vehicles is hit by an uninsured driver, your UM coverage protects your vehicle and your driver.

Frequently Asked Questions

Does commercial auto cover a technician test driving a customer's vehicle in Illinois?

For third-party liability, yes, assuming your policy includes non-owned auto coverage or appropriate garage policy provisions. If the technician causes an accident during the test drive and a third party is injured or their property is damaged, your commercial auto or garage policy responds. Damage to the customer's own vehicle is a garage keeper's liability claim. The two coverages work together for a complete picture.

Is there a difference between commercial auto rates in Chicago versus downstate Illinois?

Yes, significantly. Commercial auto is rated by garaging location, and Chicago zip codes carry substantially higher rates than downstate or suburban locations. Traffic density, accident frequency, vehicle theft rates, and legal environment all factor into territorial pricing. Two identical shops with identical vehicles and identical driver records can face very different premiums based solely on where they are located.

What is hired and non-owned auto coverage, and does my shop need it?

Hired and non-owned auto (HNOA) coverage extends your commercial auto liability to vehicles you hire or rent, and to personal vehicles your employees drive for business purposes. If a service writer uses their own car to make a bank deposit and gets into an accident, your shop may face vicarious liability. HNOA coverage addresses that exposure. Most commercial auto policies for small businesses include HNOA or offer it as an inexpensive endorsement.

Do I need commercial auto if I only have one service vehicle?

Yes. Any vehicle used for business purposes needs commercial auto coverage, even if it is just one pickup truck. A single-vehicle commercial auto policy is available from most carriers and is often priced competitively for small shops. The risk of operating even one vehicle without proper coverage is the potential for an uncovered liability claim that could exceed your shop's total assets.

How does a loaner vehicle affect my commercial auto policy?

A loaner vehicle owned by your shop needs to be scheduled on your commercial auto policy. When a customer drives that loaner, your liability coverage applies if the customer causes an accident and the policy extends to permissive users. Confirm with your agent that your policy language covers non-employee drivers of your loaner vehicles and that the liability limits are adequate.
