Tow Truck Insurance Requirements by State (and for Police Rotation Lists)

There is no national tow truck insurance minimum you can memorize, because the number that governs you depends on where you operate and what work you take. This guide explains the layers so you can figure out what actually applies to your trucks, and points you to the authoritative sources to confirm the current figures.

Layer 1: State requirements

Every state requires commercial auto liability on tow trucks, but the minimum limit varies, and many states treat towing as a regulated for-hire activity with its own permits. States commonly address:

• Minimum auto liability limits — often stated as a combined single limit or as split limits, and frequently higher for heavier trucks.
• On-hook / cargo requirements — some states require proof you can cover the vehicles you tow.
• Garagekeepers and storage rules — states that regulate impound and lien sales often require storage-related coverage.
• Permits and operating authority — separate from insurance but usually tied to proof of coverage.

Because these numbers change and differ by state, verify them directly with your state motor vehicle or transportation agency. The federal state DMV directory is the fastest way to reach the right office. Do not rely on a figure a competitor quotes you; confirm it at the source.

Layer 2: City and county rules

Local governments layer their own requirements on top of the state, especially for nonconsent towing (tows without the vehicle owner's request, such as trespass and private-property tows) and for any work touching city property. Municipal ordinances may set:

• Higher liability limits than the state minimum.
• Mandatory on-hook and garagekeepers at specified amounts.
• Secured, lit, and fenced storage lot standards.
• Business licensing and per-truck permits.

If you operate in multiple jurisdictions, you are effectively bound by the strictest one you serve. Build your program to the highest limit you need, not the average.

Layer 3: Police rotation lists and municipal contracts

Getting on a police rotation list, the roster of tow companies a department calls for accident and law-enforcement tows, is where insurance requirements jump. These are competitive, revenue-rich contracts, and agencies protect themselves accordingly.

What rotation lists commonly require

An additional insured endorsement is nearly universal. It adds the agency or municipality to your policy as a protected party so your coverage responds if they are named in a claim arising from your towing. A plain certificate is not the same thing; the endorsement is what actually extends protection, and reviewers know the difference.

Contracts also tend to require that your certificate stay continuously in force and that the agency be notified before cancellation. A lapse can knock you off the rotation, so continuous coverage is not just good practice, it is a contract term.

Federal requirements: interstate for-hire towing

If you tow for-hire across state lines, you move into federal territory. The Federal Motor Carrier Safety Administration sets financial-responsibility minimums and requires proof-of-insurance filings for interstate for-hire carriers, and towing of vehicles hauling regulated cargo or crossing state lines can trigger these rules. Review the current requirements at the FMCSA insurance requirements page and confirm whether your operation needs operating authority and filings such as the BMC-91.

Intrastate-only operators generally follow state rules rather than FMCSA filing rules, but the safest move is to confirm your classification rather than assume it.

How to make sure you actually qualify

• Get the written requirements. Ask the agency or jurisdiction for their exact limits, forms, and endorsement language in writing.
• Match limits to the strictest contract you serve, then keep them there so you never fall short mid-term.
• Confirm the additional insured endorsement is on the policy, not just referenced on a certificate.
• Keep on-hook and garagekeepers sized correctly for the vehicles you recover and store.
• Track renewal dates and filings so nothing lapses and costs you a contract.
