Insurance for Mobile Mechanics
Working out of a van means every brake job happens in someone else’s driveway or parking lot, with your scanners riding along and the Bureau of Automotive Repair setting rules on how you register, advertise and invoice. We look for mobile mechanic insurance that follows the work from your van to the customer’s car, and the insurer decides after reviewing the repairs you do, your vehicles and your claim history.
A BAR registration for every repair van
California makes it unlawful to run a mobile automotive repair business without a current Automotive Repair Dealer (ARD) registration with BAR, under 16 CCR 3351.7.3(a). Mobile repair means a technician traveling by motor vehicle, with tools and equipment, to repair a car at the customer’s location. Each vehicle used for that work needs its own ARD registration number.
The van itself carries the paperwork too. It must show the firm name and ARD number in clearly visible type at least 72 point, about three-quarters of an inch high, along with the phone number on file, and every customer gets a copy of the official ARD consumer sign with the work order. Registration renews every year, so keep each van’s ARD number handy when you request a quote.
What changed on October 1, 2025
BAR’s updated rules took effect October 1, 2025. A mobile ARD applicant now gives a physical address where records are kept for inspection; P.O. boxes, mailbox services and virtual mailboxes don’t qualify. A shop doing mobile work more than 50 miles from its registered location needs a separate registration. Final invoices list the street address, city and ZIP where the repair was done, or a description such as cross-streets, a landmark, a mile marker or a freeway ramp.
Online ads from any ARD now show the BAR-registered firm name, ARD number and phone number, and referral or concierge services that collect payment for repairs someone else performs register as ARDs too. Keep your vehicle list, records address and policy schedule matching the registration so a claim file and a BAR file tell the same story.
Mobile mechanic liability insurance for work that fails later
The defining exposure for a mechanic shows up after you’ve driven away: a caliper bolt left loose, lug nuts not torqued, the wrong fluid in a transmission, and a crash or engine failure a week later. That is completed operations, and it sits in garage liability or a general liability policy written for auto repair. Garage liability is a form we ask insurers about for mechanics, and we describe every repair type you take on so the policy fits the work.
Work on site brings its own claims. A fire or a fluid spill can damage the customer’s garage, driveway or the car parked next to yours. Spilled oil and coolant also raise cleanup questions that standard general liability pollution exclusions limit; pollution cover for fluid handling is something an insurer may add. Our auto repair shop page covers the fixed-bay version of these risks.
The customer’s car on your jack
A jack slips, a car rolls off ramps on a sloped driveway, or a test drive ends in a fender bender. General liability and business auto policies generally exclude property in your care, custody or control, and a car you are working on is exactly that. Garagekeepers coverage, or on-site customer auto coverage, is what we ask insurers about here; for a mobile mechanic it matters less for overnight storage and more for damage during the job.
Options many carriers offer are legal liability, which pays only when you are at fault; direct excess, which pays regardless of fault after the owner’s auto insurance; and direct primary, which pays first regardless of fault at the highest premium. Test drives also need auto liability that extends to driving customers’ vehicles.
The van, the scanners and the toolbox
A personal auto policy can deny a claim when the van is used for business, so the service vehicle belongs on commercial auto, listing each van and each person who drives it. Diagnostic scanners, jacks, lifts and hand tools stolen from a van overnight are an inland marine loss: a tools and equipment floater covers gear that travels, and our inland marine guide explains how those forms work.
Estimates, used oil and paperwork that keep claims small
Business and Professions Code 9884.9 requires a written estimate for parts and labor before any work, and no work or charges start until the customer authorizes them. Extra charges need consent after you find the shortfall, and oral consent is recorded on the work order. A BAR complaint or fine over an unauthorized charge isn’t something insurance pays, and clean paperwork is what prevents it.
Used oil is regulated as well. DTSC requires a California or U.S. EPA ID number for each site where a business generates, accumulates or stores used oil, businesses cannot transport hazardous waste without one, and used filters must be drained and labeled within set time limits. Ask DTSC which address it treats as your site when you work from a van.
Workers’ comp for technicians on the road
Cars falling off jacks, burns and being struck at a roadside job are the injuries workers’ comp answers for a mobile tech. WCIRB class 8389, Automobile or Truck Repair Facilities, covers mechanical repair for others on a fee basis: engines, brakes, suspension, exhaust, electrical and A/C. Its wording doesn’t mention mobile work, but it applies to mechanical repair not more specifically described, so it is the class we expect an insurer to start from and confirm. Towing or roadside service on vehicles you don’t own is classed separately as 7227, covered on our tow truck page.
What mobile mechanic insurance costs
There is no published median for mobile mechanics alone. The nearest figures are Insureon’s for its small-business customers in auto repair and mechanics, updated in April 2025 and based on shops: general liability at $54 a month ($652 a year) for $1 million per occurrence and $2 million aggregate with a $500 deductible, workers’ comp at $150 a month ($1,796 a year), commercial auto at $103 a month ($1,227 a year) and a business owner’s policy at $149 a month ($1,787 a year). They are national figures for solo and very small operators at standard limits, published industry data rather than a Mithril1 quote, and a mobile business with several vans pays well above them.
Auto is priced per van and driver, and comp per $100 of payroll. WCIRB’s pure premium rate for 8389 is $3.239 from September 1, 2026, up from $2.290 in 2024. One technician on $60,000 of payroll works out to $1,943.40 ($60,000 / 100 x $3.239). That rate covers expected losses only; insurers file their own, typically higher, rates.
Costs rise with brake, steering and EV or diesel work, test drives, more vans, drivers with violations, high tool values and past claims. They fall with clean records, signed estimates and authorizations on every job, photos of the car before work starts, locked tool storage and a higher deductible. The insurer prices the risk after its review.
A few useful answers
Common questions
Do I need a BAR registration to repair cars out of a van?
Yes. California requires a current ARD registration for mobile automotive repair, with a separate ARD number for each vehicle used and the firm name, number and phone shown on the van.
What did BAR change for mobile repair on October 1, 2025?
Applicants give a physical records address, shops working more than 50 miles out need a separate registration, invoices list where the repair happened, and online ads show the firm name, ARD number and phone.
If a brake job fails a week later and causes a crash, which policy responds?
That is completed operations, the part of garage liability or an auto repair general liability policy that covers injury or damage after the work is finished.
Is the customer’s car covered while it is on my jack?
Not by general liability, which generally excludes property in your care. Garagekeepers or on-site customer auto coverage is the cover we ask insurers about for damage during the job.
Can I get mobile mechanic insurance through Mithril1?
It can be arranged when an insurer accepts the application after reviewing your ARD registration, vans, repair types and driving records. We request the auto, liability, tools and comp lines your work needs.
