For a towing company, commercial auto liability is the policy that carries the largest share of the risk. Every call puts a heavy truck on public roads, often at night, in bad weather, and on the shoulder of a live highway, with a customer's vehicle attached. When something goes wrong, the claim is usually large and the other party is usually a member of the public. This guide explains what auto liability typically covers for tow operators, the minimum limits that apply, where coverage gaps commonly appear, and the operating habits that keep claims down.
What commercial auto liability does for a tow operator
Commercial auto liability typically pays for bodily injury and property damage you cause to others arising from the ownership, maintenance or use of a covered auto, and it usually includes the cost of defending you in a lawsuit. For a tow company, that includes collisions while driving to or from a call, backing incidents in a customer's lot, and a towed vehicle that comes loose and strikes another car.
What it typically does not cover is just as important. Most auto policies exclude damage to property in your care, custody or control, which means the customer's vehicle on your hook or in your yard is usually not covered by your auto liability. Damage to your own truck is a separate physical damage coverage, and injuries to your own employees fall under workers' compensation. Policy forms and exclusions vary by carrier, so the wording of your own policy controls.
| Exposure | Coverage that typically responds | Common gap to check |
|---|---|---|
| Your truck injures a motorist or damages another vehicle | Commercial auto liability | Limits too low for a serious injury claim |
| The customer's car is damaged while being towed | On-hook (towing) coverage | Per-vehicle limit below the value of trucks, RVs or luxury units you tow |
| Vehicles damaged or stolen while stored in your yard | Garagekeepers / vehicle protection coverage | Theft, vandalism or fire not included; legal-liability-only form |
| Damage to your own tow truck | Auto physical damage (collision and comprehensive) | Stated values out of date after equipment upgrades |
| Employee driver hurt on the job | Workers' compensation (in Washington, L&I) | No stop gap employers liability on the general liability policy |
| Employee runs a parts errand in a personal car | Hired and non-owned auto liability | Not added to the policy |

Minimum limits: federal and Washington rules
Statutory minimums are floors, not recommendations. Two sets of rules matter for most tow operators in our region.
Federal financial responsibility
According to the Federal Motor Carrier Safety Administration, for-hire tow trucks with a GVWR or GCWR of 10,000 pounds or more performing emergency moves in interstate or foreign commerce must maintain at least $750,000 in financial responsibility. For-hire tow trucks performing secondary moves (relocating a vehicle after the emergency tow) must carry the level that applies to the commodity being transported. The schedule in 49 CFR 387.9 sets $750,000 for nonhazardous property and higher levels, $1,000,000 or $5,000,000, for many hazardous materials. If you tow across state lines, confirm with your broker and FMCSA which rules apply to your operation.
Washington registered tow truck operators
Washington requires registered tow truck operators to carry insurance under RCW 46.55.030. The statute sets minimums of:
- $100,000 liability per occurrence for bodily injury or property damage.
- $50,000 of legal liability per occurrence to protect against damage to vehicles in your custody, including risks such as fire and theft, from the time the vehicle enters your custody until it is redeemed or sold.
- A $5,000 surety bond payable to the state.
Minimums rarely match real exposure
A single crash involving a heavy wrecker can produce injury claims far beyond $100,000. Motor clubs, law enforcement rotation programs, municipalities and commercial accounts frequently require higher limits, specific endorsements and additional insured status in their contracts. Read each agreement before you sign it, and send it to your broker so your policy can be matched to it.
Who is driving, and who is insured
Auto liability underwriting starts with drivers. Carriers look closely at motor vehicle records, years of towing experience, and how you hire and supervise. Gaps commonly come from the way drivers and trucks are arranged rather than from the policy itself:
- Unlisted or unapproved drivers. Some policies restrict coverage to scheduled or approved drivers. Add new hires before they take a truck out.
- Owner-operators and leased trucks. When a driver brings their own truck under your name, confirm in writing whose policy is primary and whether the truck is scheduled on yours.
- Personal vehicles. Employees who run errands in their own cars can expose the company. Hired and non-owned auto coverage typically responds to the business's liability in that situation.
- Family members and off-hours use. Set a written policy on personal use of company trucks and enforce it.
Strong hiring and qualification files help both safety and pricing. Our articles on driver hiring and screening and new tow operator training cover the details.
The loss drivers behind tow truck auto claims
Towing is hazardous work. A NIOSH study of 2011–2016 federal data found 191 towing industry deaths, an average rate of about 43 per 100,000 workers per year, more than 15 times the rate for all private industry. Motor vehicle incidents were the leading cause, and many involved workers on the roadside being struck by passing traffic. The same conditions that injure operators also generate liability claims.
Roadside scenes
Unprotected scenes invite secondary collisions. Washington's move over law requires drivers approaching an emergency zone, including tow trucks with flashing lights, to move over or slow down. See roadside safety.
Backing and tight lots
Backing into a disabled vehicle or around a parking lot is a frequent source of property damage claims. Use spotters and get out and look.
Load securement
A vehicle that separates from a wheel lift or slides off a deck can strike other motorists. Check straps, chains and safety lights before every move.
Speed and fatigue
Long shifts, overnight calls and pressure to clear scenes quickly add up. Set call-time expectations that do not reward speeding.
Practical steps to reduce auto liability claims
- Pull motor vehicle records at hire and at least annually, and set written standards for violations and accidents.
- Train on scene setup: truck positioning, lighting, cones or flares, and where the operator stands while working.
- Adopt a written phone policy. Dispatch should not expect drivers to answer while moving. See distracted driving policies.
- Use telematics and cameras. Forward and driver-facing video can show what really happened in a disputed crash. See telematics for fleet safety.
- Inspect equipment daily. Wheel lifts, booms, winch cables, lights and brakes all contribute to crash risk. See tow truck maintenance.
- Document every tow: photos of the vehicle at pickup, time stamps, and the condition of the scene.
- Report every incident to your broker promptly, even minor ones. Late notice can complicate a claim.
Building the rest of the program around auto liability
Auto liability works best as part of a coordinated program. Tow operators commonly add:
- On-hook coverage for vehicles in tow, with a per-vehicle limit that fits the largest units you handle.
- Garagekeepers coverage for vehicles in your yard, ideally written to include theft, vandalism and fire. Our storage lot security guide covers the controls carriers look for.
- Commercial umbrella or excess liability to sit above the auto and general liability limits. See commercial umbrella insurance.
- General liability for premises and operations exposures that are not auto-related, such as a customer slipping in your office.
Ask about safety credits
Some carriers give weight to documented driver training, telematics, camera programs and a clean loss history. Results vary by carrier and are never guaranteed, but a well-documented safety program gives your broker more to work with at renewal.
When to call a broker
Call us before you sign a motor club or rotation agreement, add a heavy-duty wrecker or rollback, start towing across state lines, take on repossession work, or hire drivers with less experience than usual. Each of these can change what your policy needs to say. As a broker, we compare options across the market and shape coverage around how you work. Learn more about our tow truck insurance program.
