What is On-Hook Towing Insurance?

Tow Truck Insurance Towing Insurance on‑hook towing coverage

Quick Answer: On-hook towing insurance covers physical damage to a customer’s vehicle while it is connected to your tow truck and being transported, from causes like collision, fire, theft, or upset during the tow. It does not cover vehicles stored on your lot (that is garagekeepers), and it is essential for any for-hire tow operator. Most operators carry $50,000 to $100,000 in on-hook limits.

On-hook coverage is the heart of a towing policy, and one of the most misunderstood. It protects the vehicle in your care during the most dangerous moment: while it is hooked to your truck and moving. Here is how on-hook works, what limit to carry, and what it costs.

Towing high-value vehicles?

Your on-hook limit needs to match what you haul. We size on-hook and garagekeepers coverage to your real exposure and shop specialty towing carriers. No agency fees, ever.

What on-hook towing insurance covers

On-hook (also called on-hook towing or in-tow coverage) pays for physical damage to the vehicle you are towing while it is connected to your truck and in transit. Covered causes typically include:

Collision or upset during the tow
Fire
Theft of the vehicle while in your care
Vandalism
Weather events while in transit

What on-hook does not cover

Vehicles parked or stored on your lot (that is garagekeepers)
Damage from improper hookup or negligence, depending on the policy
Personal items inside the towed vehicle
Your own tow truck (that is physical damage on your commercial auto policy)

On-hook vs. garagekeepers: know the handoff

The single most important thing to understand is when coverage switches from on-hook to garagekeepers:

Coverage	Applies when	Example
On-hook	The vehicle is connected to your truck and moving	A car is damaged while being winched or towed
Garagekeepers	The vehicle is parked or stored on your lot	A car on your impound lot is stolen overnight

Most operators need both. A gap between them is where uncovered claims happen.

What on-hook limit do I actually need?

Your on-hook limit should cover the most expensive vehicle you realistically tow, not the average one. Most operators carry $50,000 to $100,000, but if you tow luxury vehicles, multiple cars, or heavy equipment, you need more. If your limit is below a vehicle’s value, the gap comes out of your pocket.

See how an underinsured on-hook claim plays out

You tow a $90,000 vehicle but carry only a $50,000 on-hook limit. A chain fails and the vehicle sustains $70,000 in damage. The carrier pays up to $50,000 (minus your deductible), and you are personally responsible for the remaining $20,000, plus the damage to your reputation with that customer. Matching your limit to what you actually haul prevents this.

How much does on-hook coverage cost?

On-hook is usually a line within your full towing program, not a standalone policy. A complete tow program runs roughly $5,000 to $15,000 per truck per year, with on-hook a modest part of that. See our tow truck insurance cost guide, Illinois cost guide, and full breakdown of what towing insurance covers.

Frequently asked questions

What does on-hook towing insurance cover?

Physical damage to the vehicle you are towing while it is connected to your truck and in transit, from collision, fire, theft, vandalism, or upset.

What on-hook limit do I need?

Most operators carry $50,000 to $100,000, but the right limit covers the most expensive vehicle you tow. If you haul luxury or multiple vehicles, carry more so a single loss is not capped below the vehicle’s value.

What is the difference between on-hook and garagekeepers?

On-hook covers a vehicle while it is being towed. Garagekeepers covers vehicles parked or stored on your lot. A complete towing program includes both.

Does on-hook cover vehicles on my storage lot?

No. Once a vehicle is off the hook and stored on your property, garagekeepers applies, not on-hook.

How much does on-hook coverage cost?

On-hook is usually part of a full towing program that runs roughly $5,000 to $15,000 per truck per year. On-hook itself is a modest portion of that total.
