A repair shop program is built around who is legally responsible for a customer's vehicle while it is on the property — a question ordinary general liability does not fully answer.
The general liability form written for the auto service trade — premises and operations exposure, plus completed operations for work already finished. It is the base policy a shop is underwritten on, distinct from a standard BOP written for a non-automotive business.
Answers physical damage to a customer's vehicle while it is in the shop's care, custody or control — a fire, theft or collision in the lot or bay. It can be written legal liability (responds only if the shop is at fault) or direct primary (responds regardless of fault), and which basis applies changes who pays first after a loss.
Employee-owned and shop-owned tools, diagnostic equipment and lift hardware are not automatically covered by a standard property form. Scheduling them separately, through an inland marine or tools-and-equipment endorsement, is what prevents a tool loss from being underinsured by a flat contents limit.
Tow trucks, courtesy vehicles, parts runs and service calls made in shop-owned vehicles. Rated separately from the garage form, and worth reviewing alongside it so a vehicle is not left covered by neither.
Technicians work with lifts, power tools and pressurized systems, which rates differently from clerical or sales staff at the same location. Michigan's statutory criteria determine when coverage is required; where it is, classification accuracy across a mixed shop-and-sales staff is worth checking.
Additional limit above the garage liability and commercial auto liability exposure — the shop's legal responsibility for injury or damage arising from its operations, not the garagekeepers coverage on customer vehicles themselves. Whether and how an umbrella responds over garagekeepers or other property coverage depends on the specific form and underlying schedule, and should be confirmed rather than assumed. A lot carrying higher-value vehicles is still a reason to review the liability limit, since a single serious incident can exceed a limit set for an average day.
Garage risks are underwritten on operations and vehicle values on the lot, not just years in business. These are the items that move the account.
General repair, collision, transmission, tire and quick-lube work all carry different loss profiles, and welding, painting or frame work in particular are rated apart from routine maintenance. What the shop actually does — not just its name — sets the classification.
Two figures matter here, not one: the highest-value individual vehicle the shop might have in for service, and the combined value of every customer vehicle that could realistically be on the lot or in the bays at the same time. A fire or a lot-wide loss exposes the second figure, not just the first. Garagekeepers limits and deductibles are commonly set per vehicle and separately per occurrence or location, so both numbers — and how the deductible applies — are worth confirming with the carrier rather than assumed from a single average.
Who is allowed to drive a customer's vehicle, and under what conditions, is a question carriers ask directly. Technicians test-driving on public roads extends the exposure past the physical premises.
Anyone who moves vehicles — technicians, porters, lot staff — is effectively a rated driver for the operation, whether or not they are on a formal driver list. Motor vehicle records for that group are reviewed the same way a delivery fleet's drivers are.
Used oil, solvents, refrigerant and batteries create environmental exposure that a standard liability form addresses only in part. How these materials are stored and disposed of — and whether the shop uses a licensed hauler — is a underwriting question, not just a compliance one.
Lot lighting, fencing, alarm coverage and key control affect the garagekeepers exposure, since theft and vandalism are among the more frequent losses on a lot full of other people's vehicles.
Not every carrier asks for every item, but a garage submission moves faster when this is assembled up front.
Direct answers to what Michigan repair shop owners ask before moving a program.
Most Michigan repair shops carry garage liability, garagekeepers coverage for customer vehicles in their care, commercial auto for shop-owned vehicles, and workers' compensation once the statutory criteria are met. The right combination depends on the services performed and the vehicles regularly on site.
Garage liability is general liability for the auto service trade — injury or property damage arising from shop operations. Garagekeepers is a separate coverage for physical damage to a customer's own vehicle while it is in the shop's care, custody or control. A shop can carry one without the other, and a claim involving a customer's car specifically needs garagekeepers to respond.
Only if garagekeepers coverage is in place, and only on the basis it is written. A legal-liability form responds when the shop is at fault for the damage; a direct-primary form can respond regardless of fault, up to the policy terms. Which basis applies is worth confirming before a loss, not after.
Only if scheduled or covered by an inland marine or tools-and-equipment endorsement, which is separate from the garage and property forms. Technician-owned tools in particular are a common gap, since a shop's own property coverage does not automatically extend to equipment employees bring themselves.
At minimum: services performed, number of bays and technicians, the highest-value customer vehicle typically on site, who is authorized to test-drive customer vehicles, hazardous-material handling, lot security, and currently valued loss runs. With those in hand most shops can be marketed to several carriers at once.
We can review your current garage program against what the shop looks like today — services performed, bays, staff and the customer vehicles that pass through.
| Customer vehicles | Highest-value and combined customer vehicle values against current limits |
|---|---|
| Garagekeepers terms | Legal liability vs. direct primary basis, and the limit that applies |
| Tools | Whether employee-owned and shop tools are scheduled, or left to a flat contents limit |
| Property | Building and contents values against current replacement cost |
Your current declarations page, renewal date, any renewal offer, and a summary of what's changed — new bays, added services, staff changes — starts the conversation. You don't need it all ready before you call.
Titanium Shield Insurance Agency is an independent commercial agency in Rochester Hills. We review garage programs against what the operation actually does — services performed, vehicle values on the lot, and who drives what — and place garage liability and garagekeepers coverage across carriers rather than through one company.
