Coverage Types for Auto Mechanics

These are the key insurance policies most relevant to your business type — ranked by importance.

🔑

Garagekeepers Liability

Required

The most critical coverage for any mechanic or repair shop — covers damage to customers' vehicles while in your care, custody, or control: fire in your shop, theft of a customer vehicle overnight, hail damage in your parking lot, or accidents during test drives. Standard GL explicitly excludes vehicles in your care — you need garagekeepers separately.

🛡️

General Liability

Required

Covers customer slip-and-falls in your shop, bodily injury from shop operations, and property damage not involving customer vehicles. Required by commercial leases and most business registration requirements.

🦺

Workers' Compensation

Required

Required in most states with any employees. Auto mechanics face significant injury risk: jack failures, vehicle falls, chemical burns from brake fluid and battery acid, exhaust inhalation, and cuts from sharp components. WC covers medical bills and lost wages.

🏎️

Garage Liability

Highly Recommended

Combines GL + garagekeepers + test-drive coverage in a single garage policy. Most auto repair shops should use a garage policy rather than a standard GL + garagekeepers endorsement — it's specifically designed for the automotive service industry and covers the test-drive exposure that standard GL excludes.

🏢

Commercial Property

Highly Recommended

Covers your shop building (if owned), equipment, lifts, diagnostic tools, and inventory. Garage equipment is expensive — a single four-post lift costs $5,000–$20,000. A BOP combining property and liability is cost-effective for smaller shops.

What You Need to Know

→Standard GL has a care/custody/control exclusion — it does NOT cover customer vehicles in your shop. You need garagekeepers liability or a garage policy specifically.
→Test drives are one of the most common claims — an employee test-driving a customer's car after repair is covered by garagekeepers/garage liability, not standard auto insurance.
→A fire in your shop that destroys 5 customer vehicles could cost $150,000–$500,000+ in customer vehicle replacement — garagekeepers covers this catastrophic scenario.
→Completed operations matters for mechanics too — an improperly torqued wheel that fails on the highway, causing an accident, is a completed operations claim under your GL.
→State licensing for auto repair shops varies: some states require shop bonds, repair facility registrations, and specific insurance minimums to operate legally.

Frequently Asked Questions

What's the difference between garagekeepers and garage liability?+

Garagekeepers liability specifically covers damage to customers' vehicles while in your care (fire, theft, hail, accidents). Garage liability is a broader policy designed for auto service businesses that combines: (1) operations liability (what standard GL covers — customer injuries in your shop), (2) products and completed operations (your repair work that causes subsequent damage), and (3) garagekeepers (customer vehicle damage). Most auto repair shops should have a garage policy rather than trying to patch together separate GL + garagekeepers endorsements.

Does my standard auto insurance cover test drives?+

No. Standard personal or commercial auto covers vehicles you own. A customer's vehicle you're test-driving is not covered by your auto policy — it's covered by garagekeepers liability or garage liability. If an employee test-drives a customer's car after a brake job and gets rear-ended, that's a garagekeepers claim for the customer's vehicle damage. Bodily injury from the accident may involve both garagekeepers and GL. Ensure your policy covers test drive exposure — some low-cost policies limit or exclude it.

What if a customer claims my repair caused an accident?+

If a brake job you performed fails and causes an accident, the injured party can sue you for the resulting bodily injury and property damage. This is a completed operations claim under your garage liability or GL. Completed operations coverage responds to injuries and damage that occur after the work is finished and the customer has left your shop. Document all repairs thoroughly — work orders with customer signatures, parts records, and technician notes are your defense in completed operations claims.

Do I need insurance if I work on cars from my home garage?+

Yes — and your homeowners policy will NOT cover business operations. If you repair customers' vehicles at home, you need at minimum: GL (covers customer injuries on your property), garagekeepers (covers customer vehicles in your care), and commercial auto if you use a personal vehicle for business purposes. Some carriers offer mobile mechanic or small shop policies for home-based operations. Additionally, check local zoning — many residential zones prohibit commercial auto repair, which can affect your insurance eligibility.

How much garagekeepers coverage do I need?+

Calculate your maximum potential exposure: if your lot holds 15 vehicles with an average value of $30,000 each, your maximum exposure is $450,000. Your garagekeepers limit should cover at least your realistic worst-case scenario — a fire or major theft event that damages multiple customer vehicles simultaneously. Most small shops carry $100,000–$250,000 in garagekeepers; larger dealerships and service centers carry $500,000–$1M+. The cost of garagekeepers is relatively modest compared to the catastrophic claim it prevents.
