Mobile Mechanic Insurance Requirements by State (2026): All 50 States

A customer’s bumper does not care that your personal auto policy “thought” the van was for Costco runs. A dropped battery does not care about your LLC. A platform’s COI exhibit does not care that your state only asks for financial-responsibility minimums.

That’s why mobile mechanics get insurance questions the moment the work leaves a bay and lands in someone’s driveway — and why “I’m small, I’ll skip garagekeepers” is a lottery ticket you do not want to cash.

Here’s the honest contrast with pest and locksmith insurance maps: very few states publish a mobile-mechanic GL dollar floor. What you face is commercial-auto FR law, repairer/shop bonds in a handful of states, WC for employees, city ARF overlays (Houston is the textbook), and whatever fleets / property managers / on-demand platforms typed into the exhibit. License minimum ≠ contract minimum. ASE is still not insurance.

This guide is the 2026 map — board floors where we pulled primary sources, soft language where the data is thin, and the COI reality that shows up on real vans. Sister post for the license card itself: Mobile Mechanic License Requirements by State (2026).

What insurance mobile mechanics actually buy

You are not buying “ASE insurance.” You are buying a stack that covers the van, the customer’s car under your hands, the driveway you are standing in, your tools, and your people.

Line	What it covers	Typical ask	Legal status
Commercial Auto	Liability (and usually physical damage) for the service van/truck used for business	Often $1M CSL on fleet / platform COIs	State FR law sets liability floors for all drivers (e.g., CA 30/60/15, TX 30/60/25). Personal auto usually excludes business use. Commercial limits are mostly contract-driven above the floor.
Garagekeepers Liability	Damage to customer vehicles in your care, custody, or control (driveway or lot)	Often $50k–$250k+ per vehicle / stated schedule; sometimes direct primary	Not a universal state mandate — effectively mandatory for operators. Standard CGL typically excludes CCC of others’ autos.
General Liability / Garage Liability	Bodily injury & property damage (customer slips on your oil spill; you damage a garage door or landscaping)	$1M / $2M on most commercial COIs	Industry practice / contract. Few states set mechanic-specific GL dollars; bonds (CT/MA) are not the same as GL.
Tools / Equipment Floater (Inland Marine)	Diagnostic gear, toolboxes, compressors scheduled in/out of the van	Commonly $10k–$50k+ scheduled	Optional but strongly recommended — van comprehensive is not a substitute.
Workers’ Compensation	Employee injuries (burns, crush injuries, road exposure, lifting)	Statutory + employers’ liability (often $100k/$500k/$100k on COIs)	State law once employee threshold is met (TX optional for most private employers as nonsubscribers).
Umbrella / Excess	Extra limits above auto + GL	$1M–$5M on larger fleet accounts	Optional unless contract requires
Surety / License Bond	Consumer / board protection tied to a repairer or shop registration	$10k–$25k where required	Only where the board/statute requires (CT, MA, HI salvage path, etc.)
Hired & Non-Owned Auto (HNOA)	Liability when techs run parts in personal cars	Often bundled with commercial auto	Contract / risk-driven — common gap for small mobile shops

Garagekeepers & the care/custody/control trap

This is the mobile-mechanic signature coverage. When you are under someone’s hood in their driveway, that vehicle is typically in your care, custody, or control. A plain commercial general liability form usually excludes damage to property in CCC — including customer autos.

Garagekeepers liability fills that hole. Forms vary:

• Legal liability — pays when you are negligent.
• Direct primary (or similar broader forms) — can respond even when negligence is contested; fleets and platforms often prefer this.

Off-premises / mobile endorsements matter. A garagekeepers form written only for a brick-and-mortar lot may not match driveway ops — tell the agent you are mobile.

State FR minimum vs. what fleets actually want

Two different games:

• Financial responsibility / board floor — keeps the van legal and (where applicable) the repairer/shop registration alive. Examples: CA auto 30/60/15; TX 30/60/25; CT $25k repairer bond; MA $10k shop bond; NY WC proof on Art. 12-A apps.
• COI ask — what the fleet account, dealership sublet, property manager, or on-demand platform typed into the exhibit. Almost always $1M / $2M GL, commercial auto often $1M CSL, garagekeepers at stated limits, additional insured / waiver language, and WC if you have employees.

Homeowners should ask for proof of liability and WC and verify with the insurer — that’s the same consumer logic as NAIC contractor scam guidance. A pretty ACORD 25 is evidence, not the policy.

High-stakes deep dives

California — BAR mobile ARD + FR 30/60/15 (no ARD GL floor)

Bureau of Automotive Repair registers Automotive Repair Dealers for for-hire diagnosis/repair including mobile. Mobile ARDs: unique registration number per repair vehicle, plate on the application, physical records address, invoice/sign rules. BAR does not publish a statewide ARD GL dollar floor or ARD surety bond — do not confuse ARD with DMV dealer bonds for selling cars. California still requires liability insurance meeting FR minimums on vehicles operated on public roads: currently $30,000 / $60,000 / $15,000. Buy commercial auto (personal policies exclude business use), garagekeepers, tools floater, and market GL. WC with any employee. Sources: BAR apply, CA DMV insurance.

Connecticut — $25k / $10k repairer bonds

Conn. Gen. Stat. § 14-52: general repairer surety bond $25,000; limited repairer $10,000. License fees and premise/zoning expectations make pure van-only models hard — confirm with CT DMV. Bond protects customers under bond terms; it is not garagekeepers or commercial auto. Sources: § 14-52, CT DMV regulated business.

Massachusetts — $10k repair shop bond

G.L. c. 100A repair shop registration with the Division of Standards: $10,000 surety bond or letter of credit. Location friction for van-only models — verify DOS practice for pure mobile mechanical. Sources: c. 100A § 2, Mass.gov apply.

New York — Art. 12-A Mobile Repair Shop + WC

DMV repair shop registration includes Mobile Repair Shop type. Packet (VS-145): property use, zoning, sales-tax Certificate of Authority, and Workers’ Comp proof if you have employees. No clear statewide GL dollar floor verified on VS-145/CR-82 for this guide. Still buy commercial auto (NY FR + PIP), garagekeepers, and market GL. Source: NY DMV open a repair shop.

Florida — FDACS MVRS (soft on GL dollars) + FR shift coming

Motor Vehicle Repair Act registration covers mobile shops. No clear statewide MVRS GL dollar floor verified on primary FDACS materials here — soft language. Current FL FR centers on PIP + PD; bodily-injury mandate changes are scheduled for Jan 1, 2027 (verify DFS/DOI before you treat a blog date as gospel). Garagekeepers + commercial auto remain the risk stack. Source: FDACS Motor Vehicle Repair.

Texas — no statewide mech card; city ARF + nonsubscriber trap

No statewide repair facility license for ordinary mobile mechanical. Houston ARF expressly includes mobile. Most private employers may opt out of WC as nonsubscribers — with notice/filing traps and loss of exclusive remedy. TX FR auto 30/60/25. Sources: TDI nonsubscribers, Houston ARF.

Michigan & Hawaii

MI: SOS repair facility registration includes Mobile facility type; major repairs need certified mechanics by category; soft on exact SOS GL dollars. HI: salvage/wrecked/dismantled work triggers ≥ $25k performance bond; ordinary mechanical dealers are not automatically under that bond — confirm category with the Motor Vehicle Repair Industry Board.

Pitfalls that sink mobile shops

1. Personal auto on service calls. Personal policies commonly exclude business use. One at-fault wreck with tools in the back = claim fight you may lose. Buy commercial auto.
2. Skipping garagekeepers. CGL usually excludes customer vehicles in CCC. Driveway work is CCC. Full stop.
3. “They’re 1099s, so no WC.” Misclassified helpers who only work your calls in your van with your tools are an audit magnet — especially CA, NY, IL, FL construction-adjacent facts.
4. LLC ≠ insurance. An LLC does not pay for a crushed fender or a burned forearm. Boards and customers still want COIs.
5. Bond ≠ liability. CT/MA/HI bonds protect under bond terms up to the bond amount. They do not replace garagekeepers or commercial auto.
6. FR minimum ≠ fleet COI. CA 30/60/15 or TX 30/60/25 will not clear a $1M CSL commercial-auto exhibit.
7. Tools only on the van’s comprehensive. Schedule diagnostic gear on a tools floater; confirm off-vehicle theft wording.
8. Texas nonsubscriber complacency. Opt out and a hurt helper can sue you in court. Fleets can still refuse you without WC.
9. Confusing dealer bonds with repair registration. Selling cars (DMV dealer bonds) is not the same as wrenching cars (BAR/FDACS/Art. 12-A/SOS).
10. Assuming ASE covers anything. ASE is a skill credential. It is not a license and not an insurance policy.

All 50 states + DC

Tags: req = clear repair-board bond, registration insurance ask, or high-signal FR + facility rule called out with primary sources; local = city/county ARF or soft-confirm dollars; no = no mobile-mechanic-specific statewide insurance mandate verified (still carry commercial auto + garagekeepers + market GL + WC).

Market note for every state: fleets and platforms commonly still ask $1M/$2M GL + garagekeepers even when the statute is silent.

FAQ

Bottom line

Insurance for mobile mechanics is commercial auto + garagekeepers + GL + tools floater + WC law + the occasional repairer/shop bond — not a neat federal “mobile wrench policy” statute. Connecticut’s $25k repairer bond, Massachusetts’ $10k shop bond, New York’s Art. 12-A WC proof, California’s BAR mobile ARD rules plus FR 30/60/15, and Texas city ARF + nonsubscriber traps are the headline calls. Everywhere else: confirm the board packet, confirm the COI exhibit, and assume the market still wants $1M/$2M with real garagekeepers.
