Mobile mechanics bring the repair shop to the customer. You work in driveways, parking lots, office parks, and roadside locations with thousands of dollars in tools and diagnostic equipment stored in your van. The insurance exposures are different from a fixed-location shop: your tools are always in transit, you're working on customers' vehicles at their locations (not in a controlled shop environment), and you're driving constantly between service calls in a vehicle that's too heavy and too commercial for a personal auto policy.
The typical coverage stack for a mobile mechanic includes garagekeepers liability for customers' vehicles you're working on, general liability for slip-and-fall and property damage at customer locations, inland marine for your tools and equipment in the van, commercial auto for your service vehicle, and workers' compensation if you have employees. This guide covers what each line does, why personal auto policies fail for service vehicles, and what fleet customers and commercial clients require on certificates of insurance.
Garagekeepers Liability for Vehicles You're Working On
Garagekeepers liability covers physical damage to customers' vehicles while they're in your care, custody, or control. If you're holding keys, performing work, or test-driving a vehicle, you have a garagekeepers exposure. Standard general liability policies exclude coverage for property in your care — you need garagekeepers.
What garagekeepers liability covers for mobile mechanics
- Collision while test-driving: You're test-driving a customer's vehicle after a repair and collide with another vehicle or a fixed object. Garagekeepers covers the damage to the customer's car, subject to your policy limits and deductible.
- Fire or explosion from faulty repair: You perform an electrical repair or fuel system work and a fire starts, damaging the customer's vehicle. Garagekeepers responds if the fire resulted from your work.
- Theft while keys in your possession: You take possession of a customer's keys to move their vehicle or test-drive it, and the vehicle is stolen. Garagekeepers covers the loss.
- Damage from lifting or jacking equipment: Your floor jack or lift fails while you're working under a customer's vehicle and the vehicle falls, causing damage. Garagekeepers covers the vehicle damage.
- Parts or fluids damage the vehicle: You install a defective part or spill brake fluid on the customer's paint, causing property damage to the vehicle. Garagekeepers responds.
Garagekeepers for mobile operations: legal liability vs. direct coverage
Garagekeepers is sold in two forms: legal liability only and direct coverage. Legal liability pays only if you were negligent — the damage resulted from your actions or errors. Direct coverage pays even if you weren't negligent (for example, a hailstorm damages the customer's car while it's parked in their driveway and you're working on it).
For mobile mechanics, legal liability coverage is almost always the right choice because your claim scenarios — faulty repair, collision during test drive, damage from your equipment — are negligence-based. Direct coverage is 30-50% more expensive and provides coverage for non-negligent events (weather, fire not caused by you) that are low-frequency exposures when you're working at the customer's location for short service windows.
Garagekeepers limits
Limits are written as a per-vehicle limit and an aggregate. Common structures for mobile mechanics: $50,000 per vehicle / $250,000 aggregate, or $100,000 per vehicle / $500,000 aggregate. If you work on high-value vehicles — luxury cars, performance vehicles, diesel trucks — verify that your per-vehicle limit is adequate. A $50,000 limit won't cover a $90,000 Tesla or a $70,000 diesel pickup if it's totaled.
General Liability for Customer-Location Work
General liability covers third-party bodily injury and property damage claims arising from your operations. Mobile mechanics create GL exposures at every customer location: you work in driveways and parking lots where pedestrians walk, you carry tools and equipment across customer property, you spill fluids or drop parts, and you work near the customer's home or building where property damage can occur.
Common mobile mechanic GL claims
- Slip and fall on fluids you spilled: You're performing an oil change in a customer's driveway and spill oil. The customer or a pedestrian slips on the oil and fractures a wrist. GL covers medical expenses and any lawsuit.
- Property damage to customer's driveway or garage: You drop a heavy tool or piece of equipment and crack the customer's driveway, damage their garage floor, or scratch their garage door. GL covers the property damage.
- Damage to adjacent property: You're working on a vehicle in a parking lot and a part you're removing falls and damages a neighboring vehicle or property. The third party's property damage claim is covered under GL.
- Fire spreads from vehicle to structure: A fire starts on the vehicle you're working on (due to your work) and spreads to the customer's garage or home. GL covers the property damage to the structure (garagekeepers covers the vehicle).
- Injury to customer or bystander: A customer or bystander is injured by your equipment, a dropped part, or a vehicle you're moving. GL covers the bodily injury claim.
Standard limits are $1 million per occurrence and $2 million general aggregate. Fleet customers and commercial property owners often require $2 million per occurrence. If your underlying GL is written at $1 million, you'll need an umbrella policy to meet those requirements.
Inland Marine for Tools and Equipment in Your Van
Mobile mechanics carry $10,000 to $50,000 in tools and diagnostic equipment in their service vans: scan tools, torque wrenches, impact guns, specialty tools, floor jacks, air compressors, battery chargers, multimeters, and manufacturer-specific diagnostic tools. Your tools are your business. If they're stolen or damaged, you can't work.
An inland marine policy covers your tools and equipment wherever they are: in your vehicle, at a customer's location, or in storage. The coverage is written on an all-risk basis, meaning it covers theft, collision, fire, vandalism, and accidental damage — subject to your deductible and policy exclusions.
Why commercial auto won't cover your tools
Your commercial auto policy covers your service vehicle — the physical van or truck. It does not cover business equipment stored inside the vehicle. Commercial auto policies contain a business property exclusion that denies coverage for tools, equipment, parts, and inventory. If your van is broken into and $20,000 in tools is stolen, your commercial auto policy won't pay the claim. Inland marine will.
Why commercial property won't cover tools in your van
If you have a home office or storage unit where you keep backup tools, those tools can be covered under a commercial property policy or a business owners policy. But tools that are in your van — in transit between jobs — are not covered by property policies because the property is not at your insured premises. Inland marine is the only coverage that follows your tools wherever they go.
Inland marine limits and deductibles
Insure your tools and equipment at their full replacement cost. If you carry $30,000 in tools and you insure only $20,000, you're underinsured by $10,000. Take an inventory of your tools, document serial numbers and purchase receipts, and provide that list to your broker. Deductibles are typically $500 to $2,500 per occurrence. Higher deductibles reduce your premium but increase your out-of-pocket cost when a theft occurs.
Commercial Auto: Why Personal Auto Fails for Service Vehicles
Personal auto policies exclude business use. If you're driving a van or truck loaded with tools and equipment to perform paid repair services, that's commercial use. If you're in an accident and your personal auto carrier discovers you were using the vehicle for business, they'll deny the claim. You need a commercial auto policy.
What commercial auto covers
- Liability for accidents you cause: You're driving to a service call and cause a collision. Commercial auto covers the other driver's bodily injury and property damage, up to your policy limits.
- Physical damage to your service vehicle: Your van is damaged in a collision, stolen, vandalized, or destroyed by fire or weather. Commercial auto's comprehensive and collision coverage pays for repairs or replacement, subject to your deductible.
- Hired and non-owned auto: If you rent a vehicle for business use or if you use your personal vehicle for occasional business errands (picking up parts), hired and non-owned auto coverage extends your commercial auto policy to those vehicles.
Standard commercial auto limits are $1 million combined single limit. Make sure your policy includes coverage for the full replacement value of your service vehicle. A $40,000 van with a $15,000 physical damage limit leaves you with a $25,000 gap if the vehicle is totaled.
How garagekeepers, commercial auto, and GL interact
When you're test-driving a customer's vehicle and cause an accident:
- Damage to the customer's vehicle is covered under garagekeepers.
- Damage to third-party vehicles or property you hit is covered under garage liability or GL (depending on your policy structure).
- Your service van (if involved in the accident) is covered under commercial auto.
Each policy covers a distinct exposure. Don't assume one covers the others.
Workers' Compensation
If you have employees — assistant mechanics, service writers, drivers — you need workers' compensation insurance. Mobile mechanics face physical hazards: lifting heavy parts and tools, working under vehicles in driveways and parking lots (uneven surfaces, no lift equipment), chemical exposure from fluids and solvents, burns from exhaust systems and engines, and vehicle accidents while driving between service calls.
Texas workers' comp: optional but commercially required
Texas is the only state where workers' compensation is optional for most private employers. You can operate as a non-subscriber, but fleet customers and commercial property owners often require proof of workers' comp before allowing you to service vehicles on their property. Without it, you're limited to residential cash customers.
Who Asks for Your Certificate of Insurance
Mobile mechanics receive certificate of insurance requests from fleet management companies, leasing companies, property management companies (for work in apartment complexes or office parks), municipalities (for roadside assistance contracts), and auto dealerships (if you service warranty work or provide mobile maintenance). Each has specific insurance requirements, and the certificate must show the exact coverage they're asking for.
Fleet and leasing company requirements
Commercial fleets and leasing companies (Enterprise Fleet, ARI, Wheels, etc.) require garagekeepers coverage, general liability at $1 million or $2 million per occurrence, commercial auto, and workers' comp. They want you to name them as additional insured on your GL and garagekeepers policies, and they often require a waiver of subrogation on all coverages.
Property owner requirements
If you service vehicles at apartment complexes, office parks, or commercial properties, the property owner will require proof of general liability (often $2 million per occurrence) and workers' comp. They want assurance that if you injure someone or damage property while working on their premises, your insurance will respond.
Certificate turnaround time
You win a contract to service a commercial fleet. The fleet manager needs a certificate naming them as additional insured on GL and garagekeepers, with waiver of subrogation on all coverages, by end of business today. Can your broker deliver? At Tenet, we issue certificates of insurance on a published 15-minute SLA, around the clock. When a delayed certificate costs you the contract, speed matters.
What Mobile Mechanic Insurance Costs
Premiums depend on your annual revenue, number of employees, the type of work you do (general repair vs. diesel vs. specialty), the value of tools and equipment you carry, your service area (urban vs. rural, high-crime vs. low-crime), and claims history. Here are realistic ranges for a Texas mobile mechanic with 1 to 5 employees and $100,000 to $800,000 in annual revenue.
- Garagekeepers Liability (legal liability, $50K-$100K per vehicle): $1,500 - $5,000/year
- General Liability ($1M per occurrence): $1,200 - $3,500/year
- Inland Marine / Tools & Equipment ($10K-$50K coverage): $800 - $3,000/year
- Commercial Auto (1-3 service vehicles): $3,000 - $10,000/year
- Workers' Compensation: $3,000 - $12,000/year
- Umbrella ($1M): $800 - $2,000/year
Total annual cost for a typical Texas mobile mechanic: $10,000 - $35,000. Solo operators with minimal employee exposure and clean loss histories will be toward the low end. Multi-technician operations working on high-value vehicles or diesel equipment with prior claims will be at the higher end.
What drives your premium
The four biggest factors that determine what you pay for mobile mechanic insurance:
- Tools and equipment value: The more tools you carry, the higher your inland marine premium. A mechanic with $15,000 in tools pays less than one with $40,000. Insure at full replacement cost but don't over-insure — only cover what you actually carry in the van.
- Type of work: General repair and maintenance carry lower premiums than diesel work, performance modifications, or electrical/computer diagnostics. Specialty work (welding, fabrication, turbo installs) is rated higher because of the increased severity exposure.
- Service area: If you work in high-crime urban areas where tool theft is common, your inland marine premium will be higher. If you work in suburban or rural areas with low theft frequency, you'll pay less.
- Claims history: Prior garagekeepers claims (vehicle damage from faulty work), GL claims (property damage at customer locations), and tool theft claims increase your premium significantly. Underwriters view claims as predictive of future loss frequency.
Common Mistakes
Using a personal auto policy for your service vehicle
The most expensive mistake mobile mechanics make is assuming their personal auto policy covers business use. It doesn't. Personal auto policies exclude coverage when the vehicle is used for business purposes. If you're in an accident while driving to a service call and your personal auto carrier discovers you were using the vehicle for business, they'll deny the claim. You'll be personally liable for the other driver's damages, your own vehicle damage, and any lawsuits. Commercial auto is not optional for a mobile mechanic — it's legally and commercially required.
Not carrying inland marine coverage for tools
If your van is broken into and $20,000 in tools is stolen, your commercial auto policy won't cover it (business equipment is excluded) and your homeowner's or renter's policy won't cover it (business property is excluded). Without inland marine coverage, you're self-insuring your tools. A single theft event can cost you $15,000 to $40,000 in replacement tools and put you out of business for weeks while you rebuild your kit. Inland marine is inexpensive relative to the exposure — $800 to $3,000 per year for $10,000 to $50,000 in coverage.
Working on customers' vehicles without garagekeepers coverage
If you're performing repair work on a customer's vehicle and you damage it — faulty repair causes a fire, you crash it during a test drive, your floor jack fails and the vehicle falls — that's a garagekeepers claim. Without garagekeepers coverage, you're personally liable for the repair or replacement cost. A single totaled vehicle can cost $30,000 to $80,000. Garagekeepers is the core coverage for any business that works on customers' vehicles.
Underinsuring your tools on inland marine
If you carry $30,000 in tools and you insure only $15,000, you're underinsured by 50%. When a theft occurs, you'll recover only $15,000 minus your deductible, leaving you with a $15,000 gap. Take an inventory of every tool in your van, add up the replacement cost, and insure to that amount. Update the value annually as you add tools. Don't guess.
Not documenting vehicle condition before you start work
When a customer claims you damaged their vehicle and you can't produce pre-existing condition documentation, you're defending a he-said-she-said claim. Document every vehicle's condition before you start work: walk-around photos on your phone, timestamped, showing existing damage and the odometer reading. When a customer files a false claim, your intake documentation is your defense and can prevent the claim from being paid.
