Tow Truck Insurance

On-hook insurance is a specialized policy designed to cover damage to a customer's vehicle while it's being towed. The name comes from the physical act of hooking a vehicle to your truck, whether by wheel-lift, flatbed, or traditional tow bar. This coverage fills the gap that your commercial auto liability policy leaves open.

Think of it this way: your auto liability covers damage your truck causes to other vehicles on the road. On-hook coverage protects the specific vehicle attached to your truck. These are two different exposures, and they require two different policies.

What On-Hook Coverage Protects

On-hook policies generally cover physical damage to the towed vehicle from the moment you hook it up until you unhook it at the destination. This includes:

• Collision damage if your truck is involved in an accident while towing
• Damage from the vehicle falling off the flatbed or detaching during transport
• Fire, theft, or vandalism that occurs while the vehicle is connected to your truck
• Weather-related damage like hail or falling tree limbs during transit



The coverage amount is typically set per vehicle, with limits ranging from $50,000 to $150,000 per occurrence. If you regularly tow luxury vehicles or heavy-duty trucks, you'll want limits on the higher end.

Common Exclusions to Watch For

On-hook policies aren't blanket protection. Most exclude pre-existing damage, which is why a thorough vehicle condition report before every tow is essential. If a customer claims you scratched their bumper but you documented the scratch before hooking up, you're protected.

Mechanical or electrical failure that occurs during towing is another common exclusion. If a transmission fails because the vehicle was towed improperly (wrong gear, wrong method), some policies won't cover it unless you carry an endorsement for improper towing. Wear and tear, tire damage from dragging, and damage caused by the vehicle owner's negligence are also typically excluded. Read your policy's exclusion list carefully, and ask your agent to walk through each one.

Garagekeepers coverage picks up where on-hook leaves off. Once a customer's vehicle is unhooked and sitting on your property, whether in a storage lot, inside a repair bay, or parked in a holding area, on-hook coverage no longer applies. Garagekeepers legal liability protects you against damage to customer vehicles while they're in your care, custody, or control at your place of business.

This coverage is essential for any towing company that stores vehicles, even temporarily. If a car sits in your impound lot overnight and gets vandalized, or a tree falls on it during a storm, garagekeepers coverage responds to that claim. Without it, you're paying out of pocket.

Protection for Stored Vehicles

Garagekeepers policies typically cover three main perils for vehicles stored at your facility:

• Comprehensive losses like fire, theft, vandalism, weather damage, and flooding
• Collision damage, such as another vehicle in your lot rolling into a stored car
• Combined coverage that includes both comprehensive and collision perils

The number of vehicles you store at any given time matters. If your lot holds 50 impounded vehicles on an average night, your aggregate limit needs to reflect that total exposure. A $100,000 aggregate limit won't go far if a fire sweeps through your lot and damages 20 vehicles.

Legal Liability vs. Direct Primary Options

This is where garagekeepers coverage gets nuanced. You'll typically choose between two forms: legal liability and direct primary.

With a legal liability policy, the insurer only pays if you're found legally responsible for the damage. If a hailstorm damages cars in your lot, that's an act of nature, and you may not be legally liable. The customer would need to file a claim on their own auto policy. A direct primary garagekeepers policy pays regardless of fault, which gives your customers better protection and keeps you from losing business relationships over denied claims.

Direct primary costs more, but many towing companies find it worth the investment. Motor clubs and AAA contracts often require it. If a vehicle owner's car is damaged while stored with you, they expect you to handle it, not send them back to their own insurer.

Does my commercial auto policy already include on-hook coverage? Usually not. Most commercial auto policies exclude damage to vehicles being towed. On-hook coverage is a separate policy or endorsement you need to add specifically.

Can I get on-hook and garagekeepers on the same policy? Yes. Many insurers bundle them into a single tow truck insurance package, which often saves 10% to 15% compared to buying them separately.

What happens if a stored vehicle is stolen from my lot? Your garagekeepers policy would cover the loss, up to your policy limits. If you don't carry garagekeepers coverage, you're personally liable for the vehicle's value.

Do I need garagekeepers coverage if I only store vehicles for a few hours? Yes. Even a few hours of storage creates liability. If a vehicle is damaged on your property for any length of time, you're responsible.

How do I document vehicle condition before towing? Take timestamped photos or video of all four sides, the roof, and any existing damage before hooking up. Many operators use apps that log GPS coordinates and timestamps automatically.

Is on-hook coverage required by law? It depends on your state. Some states require it as part of your towing license. Others don't mandate it but your motor club or municipal contracts almost certainly will.

Getting tow truck insurance right means understanding that on-hook and garagekeepers coverage aren't interchangeable. They protect different phases of your operation, and most towing businesses need both. Skipping one creates a gap that a single claim can exploit.

Start by auditing your actual exposure. How many vehicles do you tow per week? How many sit in your lot overnight? What's the most expensive vehicle you've handled in the past six months? Those numbers tell you what limits to carry.

Work with an independent agent who specializes in commercial auto and towing operations. They can compare quotes from multiple carriers and spot coverage gaps that a general business agent might miss. Get at least three quotes, and don't just compare premiums. Compare exclusions, deductibles, and whether garagekeepers is offered as legal liability or direct primary.

Your trucks are your livelihood, but the vehicles you tow and store are someone else's. Protecting them properly isn't just good business practice. It's the difference between a manageable claim and a financial disaster.
