Auto repair shops and garages need commercial auto coverage for every owned business vehicle — service trucks, tow rigs, loaner cars, and shuttle vans — with limits typically starting at $500,000 CSL and premiums ranging from $1,500 to $4,500 per vehicle annually. This is separate from Garagekeepers Legal Liability, which covers customer vehicles in your care.
Who this is for: Independent repair shops, transmission specialists, tire shops, body shops, and dealership service departments that own or operate business vehicles.
TL;DR — Key Takeaways
- Commercial auto ≠ garage policy. Your shop needs commercial auto for your vehicles; Garagekeepers covers customer vehicles.
- Minimum state liability limits are often inadequate. Most lenders and fleet clients require $1,000,000 CSL; budget accordingly.
- Test drives are a unique exposure. An employee driving a customer's vehicle for diagnosis or a test drive after repair is covered under Garagekeepers — not commercial auto.
- Hired and Non-Owned Auto (HNOA) is essential if technicians ever use personal or rented vehicles for parts runs or road calls.
- Typical annual premium: $1,500–$4,500 per vehicle for most shop operations; mobile mechanics and tow operators skew higher.
What Does Commercial Auto Cover for an Auto Repair Shop?
Commercial auto insurance covers vehicles your shop owns, leases, or hires for business use. For a repair shop or garage, covered vehicles typically include:
| Vehicle Type | Coverage Applies? | Notes |
|---|---|---|
| Shop service truck / parts runner | Yes — owned auto | Schedule on policy by VIN |
| Employee-owned car used for parts run | Yes — Non-Owned Auto | Requires HNOA endorsement |
| Rented van / loaner vehicle (shop-owned) | Yes — owned auto | Schedule on policy |
| Customer's vehicle during test drive | No — this is Garagekeepers | Separate insuring agreement needed |
| Mobile mechanic rig / road-service truck | Yes — owned auto | Often rated as "service" use; higher radius = higher premium |
| Employee driving customer vehicle to pick up parts | No — typically Garagekeepers or garage liability | Confirm with your broker |
What commercial auto pays: - Bodily injury and property damage liability — injuries or damage your vehicle causes to a third party - Uninsured/underinsured motorist (UM/UIM) — protects your driver when hit by an under-insured motorist (required in many states [verify state]) - Medical payments / PIP — first-party medical costs regardless of fault (required in no-fault states [verify state]) - Physical damage — collision — repairs to your vehicle after a crash - Physical damage — comprehensive — theft, fire, vandalism, hail, flood
What commercial auto does NOT cover: - Customer vehicles in your possession (that's Garagekeepers Legal Liability) - Bodily injury arising from your repair work itself (that's Garage Liability / General Liability) - Employee injuries while driving (Workers' Compensation applies)
How Much Does Commercial Auto Cost for Auto Repair Shops?
Premiums depend on the number and type of vehicles, driver records, radius of operation, and limits selected. The table below reflects illustrative industry-typical ranges — your actual quote will vary.
| Shop Profile | Vehicles | Typical Annual Premium Range |
|---|---|---|
| Single-location repair shop — 1 parts truck | 1 vehicle | $1,500–$2,500 |
| Mid-size shop — 2 service trucks + loaner van | 3 vehicles | $4,500–$9,000 |
| Mobile mechanic — 1 service rig, statewide | 1 vehicle | $2,200–$4,500 |
| Auto body shop — 2 trucks + shuttle van | 3 vehicles | $5,000–$10,500 |
| Towing operation (combined tow + repair) | 2–4 tow trucks | $8,000–$20,000+ |
Key premium drivers: - Driver MVR history — a single at-fault accident or DUI can increase premiums 20–60% - Radius of operation — local (under 50 miles) rates lower than regional or long-haul - Garaging ZIP code — urban areas command higher rates than rural - Vehicle weight / GVWR — heavy tow rigs (Class 6–8) are rated separately and cost significantly more - Selected limits — moving from $500K CSL to $1M CSL typically adds 15–25% to premium
What Limits Should an Auto Repair Shop Carry?
State minimum liability limits (often $25,000/$50,000/$25,000 split or equivalent CSL) are almost always insufficient for business vehicle operation.
| Limit Level | Combined Single Limit | When It's Typically Required |
|---|---|---|
| State minimum | Varies ($25K–$100K CSL) | Legal minimum; rarely sufficient |
| Standard business | $500,000 CSL | Small single-vehicle operations |
| Recommended | $1,000,000 CSL | Most commercial leases and fleet contracts require this |
| Fleet / contract work | $1,000,000–$2,000,000 CSL | Fleet management clients, government contracts |
Umbrella/Excess Liability: Most shops with three or more vehicles, or any tow operation, should carry a $1–2 million commercial umbrella over the commercial auto policy to reach adequate total limits without paying excess-layer commercial auto rates.
How to Get Commercial Auto Coverage for Your Shop — 5 Steps
- Inventory all business vehicles. Compile VINs, year/make/model, GVWR, and primary use (delivery, service, transport). Include vehicles titled in the business name and any vehicles regularly driven by employees on business errands.
- Pull driver MVRs. Carriers will order Motor Vehicle Records for all scheduled drivers. Identify any employees with DUIs, at-fault accidents, or license suspensions before binding — some carriers have hard declines.
- Choose your limits and deductibles. Decide on CSL (or split limits), UM/UIM, physical damage deductibles ($500–$2,500 is common), and whether to carry comprehensive/collision on older vehicles (ACV vs. stated value).
- Request quotes from multiple carriers. Commercial auto for garages is written by carriers that also understand the full garage risk (garage liability, garagekeepers). Bundling all garage coverages with one carrier often yields better pricing and simplifies claims.
- Bind coverage and obtain certificates (COIs). Your lender, landlord, or fleet client may require proof of insurance before you take possession of or operate a vehicle. Certificate turnaround should be same-day with the right broker.
Real-World Scenario: Mid-Size Repair Shop in Texas
This is an illustrative example to show how coverage works — not a guarantee of pricing or outcomes.
The shop: Rodriguez Automotive in San Antonio, TX — 8 bays, 12 employees, specializing in domestic and import repair. Owned fleet: one parts-runner pickup (2021 F-150), one shuttle van (2019 Transit), and one mobile diagnostic unit (2020 Sprinter).
Coverage structure: - Commercial Auto: $1,000,000 CSL, $500 comprehensive deductible, $1,000 collision deductible — approximately $7,200/year for three vehicles - Hired and Non-Owned Auto endorsement added for $220/year (technicians occasionally drive personal vehicles for emergency parts runs) - $1,000,000 Commercial Umbrella over the commercial auto and garage liability — approximately $1,800/year
The claim: A technician driving the parts truck rear-ends another vehicle at a red light, causing $38,000 in vehicle damage and $55,000 in medical bills to two occupants. Total claim: $93,000. The $1,000,000 CSL commercial auto policy pays the entire claim after the $1,000 collision deductible (for the shop's own truck damage). Without adequate limits, the shop owner could face personal liability.
Why this matters: Texas requires minimum 30/60/25 auto liability — only $30,000 per person for bodily injury. A single two-person accident like this would have exceeded state minimums by more than 3x.
Frequently Asked Questions
Does my garage policy already include commercial auto? Some garage policies (written on the ISO Garage Coverage Form CA 00 05) include a "covered auto" section that extends to owned business vehicles. However, many garage policies are structured as garage liability only, with commercial auto as a separate policy. Review your declarations page carefully — if you don't see your vehicle VINs listed, you likely don't have commercial auto coverage.
Does commercial auto cover a customer's car if my employee drives it? No. When you take possession of a customer's vehicle for service, repair, or storage, coverage shifts to Garagekeepers Legal Liability. Commercial auto does not cover vehicles in your care, custody, or control that belong to customers.
What if a technician uses their personal vehicle to pick up parts? Your commercial auto policy's Non-Owned Auto coverage (or a Hired and Non-Owned Auto endorsement) provides liability coverage when an employee uses their personal vehicle for business purposes. It protects your business — the employee's personal auto policy is primary; your HNOA is excess. Physical damage to the employee's vehicle is not covered.
Are loaner vehicles covered under commercial auto? Yes, if the loaner vehicle is titled to the business and scheduled on your commercial auto policy. Customer-provided loaners are a different matter — clarify ownership and add the vehicle to your policy at binding or endorsement.
Do I need commercial auto if I only have one truck? Yes. A personal auto policy explicitly excludes vehicles used primarily for business. If your parts truck is involved in an at-fault accident and you're relying on personal auto, the carrier will likely deny the claim. One commercial vehicle = one commercial auto policy.
Does commercial auto cover a mobile mechanic's tools inside the truck? No. Tools and equipment in the vehicle are not covered under commercial auto. You need a separate Inland Marine or Tools & Equipment policy for hand tools, diagnostic equipment, and specialty tools.
How does commercial auto interact with my workers' comp if my driver is injured? Workers' Compensation covers employee injuries that arise in the course of employment — including while driving a company vehicle. Commercial auto medical payments or PIP would be secondary or excluded depending on the state. Workers' comp is the correct first-party coverage for injured employees [verify state for no-fault interaction].
Can I add additional insureds to my commercial auto policy? Yes. Lenders (loss payees) are routinely added for financed vehicles. Fleet management clients or property owners may request additional insured status; this is handled by endorsement. Be aware that the additional insured's own negligence is typically not covered — review the endorsement language.

- Independent agency, multiple carrier options. Morrow places garage risks with multiple commercial carriers rather than being captive to one. That means your commercial auto, garage liability, and garagekeepers can be competitively quoted every renewal — not just rubber-stamped.
- Deep garage-risk expertise. Commercial auto for repair shops intersects with garagekeepers, garage liability, and inland marine in ways a generalist broker can miss.

- Claims advocacy, not just policy delivery. When a technician has an at-fault accident, we help coordinate with the carrier, document the loss, and push for fair and fast resolution — not just hand you a claim number.
- Full garage insurance package. Rather than patching together policies from three different carriers, Morrow can quote your entire garage risk (commercial auto, garage liability, garagekeepers, workers' comp, property) as a coordinated package, reducing gaps and simplifying renewals.
