Garage liability insurance: what the garage form covers
Garage liability is the liability section of the garage policy: bodily injury and property damage claims against an auto business, written in two parts, one for accidents involving the business's covered autos and one for everything else its operations do. It was drafted for dealers, repair shops carried it for decades, and the one thing it deliberately leaves out is the customer's own vehicle in your care.
Garage liability vs garage keepersTwo coverage parts: covered autos, and everything else
The garage form's liability section is built around a phrase, "garage operations," and it splits that phrase in two. IRMI records the two insuring agreements as garage operations involving the ownership, maintenance, or use of autos, and all other garage business operations (IRMI, garage liability insurance). On the ISO Garage Coverage Form, CA 00 05, those appear as "Garage Operations, Covered Autos" and "Garage Operations, Other Than Covered Autos," and RNC-Pro's archived analysis of the form quotes the auto half as damages "caused by an accident and resulting from garage operations involving ownership, maintenance or use of covered autos" (RNC-Pro, ISO Garage Coverage Form Archive).
Read the split against a working day. A technician takes a customer's car on a road test and rear-ends a pickup at a light: the pickup's driver and the pickup are the covered-autos half, because the claim arises from the use of an auto in garage operations. A customer slips on a wet showroom floor, or a brake job leaves the shop and fails a week later: the other-than-covered-autos half, the premises and products exposures a general liability policy would carry for any other business. The form puts both under one liability section because an auto business cannot cleanly separate them, and a standard general liability policy's auto exclusion would otherwise leave the first half uninsured. What "covered autos" means on your policy is set by the symbols on the declarations, which is a question to put to the agent by name rather than assume.
Who the form is written for: dealers first, repair shops by inheritance
The form is a dealer document. IRMI's definition lists its intended insureds as "franchised and nonfranchised automobile, truck, truck-tractor, motorcycle, recreational vehicle, and trailer dealers," and the garage policy it belongs to is defined as a commercial auto policy for auto dealers (IRMI, garage policy). ISO's 2013 commercial auto revision made that explicit: the Auto Dealers Coverage Form, CA 00 25, replaced the garage form for dealers, adding an acts, errors or omissions section for the finance office and keeping premises, products, auto liability, and physical damage together in one document (RNC-Pro, Auto Dealers Coverage Form overview). If you sell cars, that is the form your carrier is most likely working from, and the license side of the picture, bond and insurance conditions set by your state's motor vehicle agency, is on our dealer hub and its requirements page.
Repair shops are the inheritance. For decades a shop with no inventory and no showroom bought the same garage form because it was the only standard form that combined auto liability with premises liability, and "garage liability" became the trade's word for its liability coverage. In the same 2013 revision ISO stopped supporting the garage form for those service risks, and standard carriers moved them to a general liability policy plus a business auto policy, with garagekeepers attached as an endorsement; the change was gradual enough that much of the industry did not register it (Faber, InsNerds, 2019). Carriers with their own garage forms kept writing them, so a body shop may still see the old name on its declarations, and the coverage does the same work either way. What a body shop's version of the stack looks like, paint booth and all, is on auto body shop insurance.
What it does not do: the customer's car
Every liability form carries a care, custody, or control exclusion, which IRMI describes as eliminating coverage "with respect to damage to property in the insured's care, custody, or control," and its entry names garagekeepers as the coverage that picks the exposure back up (IRMI, care, custody, or control). For an auto business that exclusion has one obvious subject. The customer's car on the lift, in the service lane, or in the fenced lot overnight is property in your care, and the liability section will not answer for hail, theft, a dropped lift, or the road-test collision damage to that car. That is the whole reason a second coverage exists, and the three ways it can be written are on garage keepers insurance. If you are still deciding whether your operation carries one or both, that decision has its own page: garage liability vs garage keepers.
One more thing the form does not do is create a legal requirement. Repair shops rarely face a statutory insurance minimum, and even for dealers the license condition is set state by state rather than by the form; Texas, the state worked through to statute here, conditions its dealer license on a surety bond and on financial responsibility for plated vehicles rather than on a garage policy (Texas garage liability insurance). The rest of the family, and where each coverage lands by operation, is on the coverage hub.
