Commercial Auto Insurance for Auto Repair Shops in Texas: Coverage & Cost Guide

Texas has more registered vehicles than almost any other state, which means auto repair shops here stay busy. It also means your commercial auto exposure is real. Every time a technician takes a customer's car for a test drive on a Plano service road or your tow truck brings in a breakdown from I-35, your business is on the hook if something goes wrong. A personal auto policy does not cover vehicles used for business. Neither does your garage liability policy, which handles a different set of risks entirely. Commercial auto insurance is what fills that gap.

Quick Answer

Costs below are annual estimates for Texas auto repair shops with clean driving records and standard $1M/$2M liability limits.

Shop Profile	Vehicles Covered	Estimated Annual Premium
Small shop, 1-2 service vehicles	1 service truck or van	$1,800 to $2,800
Mid-size shop with loaner and tow truck	3-5 vehicles	$4,500 to $7,500
Larger multi-bay shop with small fleet	6-10 vehicles	$8,000 to $14,000

Rates vary by driver records, vehicle type, annual mileage, and coverage limits. Tow trucks carry higher premiums than passenger vehicles due to weight class and use.

What Commercial Auto Insurance Covers for Texas Auto Repair Shops

Commercial auto insurance covers your business against liability and physical damage claims arising from the use of vehicles in your operations. For auto repair shops, that breaks into several distinct exposures.

Test Driving Customer Vehicles

When a technician takes a customer's car around the block to verify a repair, that vehicle is under your care and control. Garage keeper's liability covers damage to the customer's vehicle while it is in your custody. But if your technician causes an accident during that test drive and injures another driver or damages a third party's property, that is a commercial auto liability claim, not a garage keeper's claim. The distinction matters because the wrong policy will not respond. Texas requires commercial auto liability coverage if you are operating vehicles in connection with your business, and test driving qualifies.

Shop-Owned Service Vehicles

Any vehicle titled to your business or regularly used by your employees to run shop operations needs commercial auto coverage. This includes the pickup truck you use to pick up parts, the van for mobile oil changes or roadside work, and any utility vehicle on your property. If a driver in one of your shop vehicles causes an injury or property damage, your commercial auto policy covers the liability and can cover repairs to your own vehicle if you carry collision and comprehensive.

Tow Trucks and Recovery Equipment

Tow trucks are a specialized vehicle class. They carry higher premiums because of their weight, the complexity of their operation, and the added liability of towing another vehicle. On-hook coverage (which protects the vehicle being towed) is typically added as a separate endorsement rather than being part of standard commercial auto, but the underlying liability for your tow truck driver causing an accident is commercial auto territory. If your shop operates even one tow truck, get that vehicle properly classified and scheduled on your policy.

Parts Delivery and Errand Vehicles

If you send a driver to pick up a part from a nearby supplier or deliver a vehicle to a customer, that trip is a business use. Personal auto insurance excludes business use by definition. Any vehicle used regularly for parts runs, supplier trips, or customer vehicle delivery should be on your commercial auto policy.

Employee-Driven Shop Vehicles

When your employees drive vehicles owned or leased by your shop, your business is vicariously liable for their actions behind the wheel. Commercial auto coverage extends to employees operating scheduled vehicles in the course of their job duties. If you use a hired and non-owned auto endorsement, it can also extend coverage to employees using their personal vehicles for shop business, such as a service writer making a bank deposit.

What Commercial Auto Insurance Does NOT Cover

Damage to Customer Vehicles in Your Lot

If a customer's vehicle is damaged while sitting on your lot, a fire spreads from a neighboring property, or a hailstorm hits your service bays, that is not a commercial auto claim. Damage to vehicles in your custody, care, and control falls under garage keeper's liability insurance. A commercial auto policy only responds when a covered vehicle is being driven. Parked or stored vehicles require separate coverage.

Tools, Parts, and Property Inside Vehicles

Commercial auto covers the vehicle and the liability from driving it. It does not cover tools left in a shop truck or parts inventory being transported. Equipment and inventory in transit fall under an inland marine or commercial property endorsement. If you regularly carry expensive tools or customer parts in your vehicles, ask your agent about a floater.

Employees Injured in Shop Vehicles

If an employee is injured in an accident while driving a shop vehicle, workers compensation covers their medical bills and lost wages, not commercial auto. Texas is the only state where private-sector employers can opt out of workers comp, but most auto repair shops carry it given the physical nature of the work. Confirm that your workers comp is active before assuming it will respond.

Customer Vehicles Being Repaired

Commercial auto does not cover vehicles you are currently working on. A transmission you are rebuilding, an engine you are replacing, a brake job in progress: all of those vehicles need coverage under garage keeper's liability if they are going to be protected while in your shop.

Texas-Specific Considerations

Texas state law requires minimum auto liability limits of 30/60/25, meaning $30,000 per person for bodily injury, $60,000 per accident for bodily injury, and $25,000 for property damage. These are the legal minimums, not recommended limits. For a shop operating tow trucks or service vehicles, the legal minimum is almost never enough to protect your business from a serious accident. Most underwriters recommend at least $500,000 combined single limit, and $1M is standard for shops with tow trucks.

Texas does not require personal injury protection (PIP) on commercial auto policies by default, though you can add it. Unlike states with no-fault systems, Texas is a fault state for auto liability, meaning the at-fault driver's insurance covers the injured party's damages. This means if one of your drivers causes a serious accident, your commercial auto liability limit is the primary source of recovery for the other party.

The Texas Department of Insurance regulates commercial auto rates and forms in the state. Carriers must file their rates with the TDI, but Texas allows significant pricing variation between carriers. If your shop has drivers with less-than-perfect records or operates specialty vehicles like flatbed tow trucks, getting three to five quotes from carriers that specialize in commercial auto for automotive businesses will produce meaningfully different premiums.

Texas also has a high rate of uninsured motorists. Adding uninsured motorist coverage to your commercial auto policy protects your shop vehicles and drivers if they are hit by someone with no insurance. Given that Texas UM rates run around 20 percent of drivers, this is worth the added premium.

Frequently Asked Questions

Does commercial auto insurance cover test driving customer cars in Texas?

Partly. If your technician test drives a customer's car and causes an accident that injures another person or damages someone else's property, that third-party liability claim falls under commercial auto (specifically, the non-owned auto or garage operations portion of your policy). Damage to the customer's own vehicle during the test drive is a garage keeper's liability claim. You need both coverages. Confirm with your agent how your policy handles non-owned vehicles to avoid a gap.

Is a tow truck classified differently than a service vehicle?

Yes. Tow trucks are rated as a separate vehicle class by most commercial auto carriers. They are heavier, more complex to operate, and carry the added exposure of towing another vehicle. Expect tow truck premiums to run 30 to 60 percent higher per vehicle than a comparable light-duty service truck. On-hook coverage for the vehicle being towed is typically an endorsement on top of standard commercial auto.

What happens if an employee uses their own car for shop business and gets into an accident?

The employee's personal auto policy is primary. If their limits are exhausted, your shop could face liability under a vicarious liability theory. A hired and non-owned auto (HNOA) endorsement on your commercial auto policy provides secondary coverage for business use of employees' personal vehicles. Many auto repair shops add HNOA to their commercial auto policy for this reason.

How many vehicles can I add to one commercial auto policy?

There is no hard cap. Most carriers will write anywhere from one vehicle to a small fleet under a single commercial auto policy. Larger fleets (typically 10 or more vehicles) may be better served by a fleet policy with experience rating, which can reduce premiums if your fleet has a good loss history.

Do I need separate coverage for a loaner vehicle I give to customers?

Yes, and the type of coverage depends on how the loaner arrangement works. If you own the loaner and let customers drive it, your commercial auto policy can cover it as a scheduled vehicle. You also need the right liability language to cover a non-employee driver. Some shops use a garage liability endorsement to handle loaner vehicles. Confirm the arrangement with your agent before handing over keys, as a gap in coverage on a customer-driven loaner can expose you directly.
