General Liability Insurance for Auto Repair Shops

By the Repair Shop Insurance editorial team · Updated September 27, 2026

If a landlord, a fleet customer, or a lender has told you to get general liability insurance for your auto repair shop, they almost always mean a commercial general liability (CGL) policy. It’s the standard liability policy for most businesses. This guide walks through what that policy does for a shop, how to read the limits, and what it leaves for other coverage to handle.

What general liability covers for an auto repair shop

A CGL policy is built around claims from people outside your business. It generally pays for your legal defense and for damages you’re legally obligated to pay, up to the limits and subject to the policy’s terms and exclusions. The coverage is usually organized into a few parts:

Bodily injury and property damage

This is the core of the policy. It applies to injury or damage arising from your premises and your ongoing operations: a customer who trips over an air hose, a delivery driver hurt by a closing bay door, or sparks from a cutting torch that damage the business next door.

Products–completed operations

For a repair shop, this is often the part that matters most. It addresses injury or damage that happens after your work is done and the vehicle has left, such as a brake line that lets go on the highway or a wheel that separates days after a tire job. It can also apply to parts you sell or install. Completed operations coverage is included in most CGL policies, but confirm it hasn’t been limited or excluded by endorsement.

Personal and advertising injury

This part addresses a narrower set of claims, such as allegations of defamation, or of using someone else’s advertising idea or copyrighted material in your own ads. It’s rarely the reason a shop buys the policy, but it’s part of the package.

Medical payments

Medical payments coverage can pay reasonable medical expenses for someone hurt on your premises, often without anyone having to prove fault. The limit is small compared with the main limits, and it’s designed to settle minor injuries quickly. It typically doesn’t apply to your employees.

How general liability limits work

The limits on a CGL policy and on your certificate of insurance aren’t one number. They’re a set of limits that interact:

• Each occurrence. The most the policy pays for all damages from a single occurrence, such as one accident or one failed repair.
• General aggregate. The most the policy pays for all covered claims during the policy period, other than products–completed operations claims.
• Products–completed operations aggregate. A separate cap for all claims arising from your finished work and the products you sell or install during the policy period.
• Smaller sub-limits. Most policies also show separate limits for personal and advertising injury, medical payments, and damage to premises rented to you.

A common structure is $1 million per occurrence with a $2 million general aggregate, and leases and contracts often request it. That’s a convention, not a legal requirement, and it isn’t necessarily enough for your shop. If a contract asks for more, or you want protection above these limits, that’s usually handled with an umbrella policy. Our guide to insurance requirements covers how to think about how much you need.

The three big gaps for repair shops

A CGL policy is written for businesses in general, so several of its standard exclusions land squarely on the everyday work of a repair shop. Wording varies by insurance company, but these three come up for nearly every shop:

1. Auto liability

General liability generally excludes injury and damage arising from the use of autos. Road tests, parts runs, shuttling customers, and moving cars around the lot all need auto liability from somewhere else — typically commercial auto for vehicles you own, plus coverage that specifically addresses driving customers’ vehicles. Our road test coverage guide explains that second piece.

2. Customers’ vehicles in your care

Property in your care, custody, or control is generally excluded. A customer’s car damaged on your lift, burned in a shop fire, or stolen from your lot is a garagekeepers question, not a general liability one.

3. Your own work

General liability is designed for the damage your work causes to others, not the cost of correcting the work itself. If a water pump you installed fails, redoing the job typically isn’t covered, even if the failure leads to a covered claim for the resulting injuries or damage. Our faulty workmanship guide explains where that line usually falls.

Which policy responds?

These are simplified illustrations. Whether a specific claim is covered depends on the facts and on the actual policy wording.

Occurrence vs. claims-made

Most CGL policies are written on an occurrence basis: the policy in force when the injury or damage happens is the one that responds, even if the claim is made years later. That’s useful for completed operations, where a repair you did this year could lead to a claim well after the policy has expired.

Some policies are written on a claims-made basis instead, which generally responds to claims first made while the policy is in force, subject to a retroactive date. If you’re offered a claims-made form, ask about the retroactive date and what happens to coverage if you change insurance companies or close the shop.

Additional insureds: landlords and customers

Leases and commercial customer agreements commonly require that you add the other party as an additional insured on your general liability policy. That gives them certain protection under your policy for claims arising from your premises or your work. It’s granted by endorsement, and endorsements differ in what they cover and whom they include.

A certificate of insurance only summarizes your coverage; it doesn’t add anyone to the policy by itself. Contracts may also ask for a waiver of subrogation or “primary and non-contributory” wording, which also come from endorsements. Our lease and certificate guide goes through the common requests.

General liability vs. garage liability: which do you need?

You need the protection both terms describe. “General liability” is the CGL policy described above. “Garage liability” refers to liability coverage built around garage operations, sometimes written on a dedicated garage policy that also includes auto liability. Many shops are insured with a CGL policy paired with separate commercial auto and garagekeepers coverage; others use a garage policy. Either can work, as long as the combination covers premises, completed work, driving, and customers’ vehicles. Our garage liability guide explains that structure in depth.

What affects the price of general liability

General liability for a repair shop is commonly rated on revenue or payroll, adjusted for the kind of work you do. Insurance companies also look at where you’re located, how long you’ve been in business, your claims history, how much work you sublet, whether you sell parts over the counter, and your limits and deductible. Higher-hazard work, such as heavy-duty service or structural repair, can affect both price and which insurance companies are willing to offer coverage. Some policies are auditable, so an estimated revenue figure may be adjusted after the policy period. See our insurance cost guide for how the rest of a shop’s coverage is priced.
