CGL insurance for truckers covers the risks beyond the road
Your auto policy is built for the truck. General liability covers much of what happens around it, at your terminal, on a customer's dock, and in your advertising, and the line between the two decides which policy pays a claim.

General liability for truckers at a glance
CGL insurance for truckers covers third-party bodily injury, property damage, and personal and advertising injury arising from your premises and business operations, plus your legal defense. It excludes the use of your trucks, including most loading and unloading, and it excludes freight in your care, employee injuries, and your own property.
Most carriers buy general liability because a shipper, broker, or landlord asked for a certificate. That is a fine reason to buy it and a poor reason to stop reading, because CGL and your auto policy are written to fit together, and trucking claims often land right on the seam between them.
I spent more than six years in risk management before I founded Simplex, and I have led it for more than 25 years since. This guide follows the standard ISO wording to show where CGL applies, where it hands off to your auto and cargo coverage, and what to check before you sign a contract.

Key takeaways
CGL covers the business, not the truck
It pays third-party injury, damage, and advertising injury claims from your premises and operations, with defense costs paid on top of the limits.
Loading and unloading is mostly auto exposure
The CGL form treats handling freight into, on, and off your truck as use of the auto, which it excludes.
Forklifts are the exception
Freight moved by a mechanical device not attached to the truck, other than a hand truck, falls outside the auto forms and back inside CGL.
Freight needs its own policy
CGL excludes property in your care, custody, or control, and the ISO auto forms exclude property you transport.
Contracts set the CGL limit
Federal minimums apply to vehicles on public highways. CGL limits come from contracts, such as Amazon Relay's $1 million per occurrence and $2 million aggregate.
A certificate is not coverage
Additional insured status, primary and noncontributory wording, and waivers of subrogation work only through endorsements on the policy.

What does CGL insurance for truckers cover?
CGL insurance for truckers covers claims from people outside your company for injury or damage caused by your premises and operations, not by driving your trucks. The standard ISO Commercial General Liability Coverage Form (CG 00 01) has three parts.
| Coverage | What it pays | Trucking example |
|---|---|---|
| A: Bodily injury and property damage | Damages you are legally obligated to pay for injury or damage caused by an accident | A visitor falls on the stairs at your terminal office |
| B: Personal and advertising injury | Offenses such as libel, slander, disparaging another company's services, and using another's advertising idea or slogan in your ads | Your ad makes a false claim about a competitor's service |
| C: Medical payments | Medical expenses for injuries on or next to your premises or caused by your operations, regardless of fault | A shipper's employee trips in your yard |
Defense is part of the coverage. The insurer has the right and duty to defend a suit seeking covered damages, and its defense expenses are paid in addition to the limits, not out of them. That duty ends once the limit is used up paying judgments or settlements.
Occurrence or claims-made?
CG 00 01 is an occurrence form: it covers injury or damage that happens during the policy period, even if the claim arrives later. Some CGL policies use a claims-made trigger instead, which responds to claims first made while the policy is in force. Know which one you have before you change insurers.
General liability is one piece of a trucking program. For how it fits with auto liability, cargo, and physical damage, see our commercial truck insurance page.
Where does CGL stop and auto liability start?
CGL stops where the use of an auto starts. Its auto exclusion removes bodily injury and property damage arising out of the ownership, maintenance, use, or entrustment to others of any auto owned or operated by, or rented or loaned to, any insured. "Use" includes operation and loading or unloading.
That is deliberate. Your truck on the road belongs to your auto liability policy, which is also where federal rules point: 49 CFR Part 387 sets financial responsibility for motor vehicles operated on public highways. For how that policy decides which trucks are covered, see our guide to commercial auto symbols.
Does general liability cover loading and unloading?
Mostly no, with one important exception. The CGL form defines loading or unloading as handling property after it is moved from the place where it was accepted for movement, while it is in or on the auto, and while it is moved from the auto to the place of final delivery. All of that is auto exposure.
The exception is equipment. Loading or unloading "does not include the movement of property by means of a mechanical device, other than a hand truck, that is not attached to" the auto. The ISO Business Auto and Motor Carrier forms mirror that line: both exclude movement of property by a mechanical device, other than a hand truck, unless it is attached to the covered auto.
- By hand or with a hand truck: auto liability.
- With a liftgate or other device attached to the truck: auto liability.
- With a forklift, conveyor, or hoist not attached to the truck: CGL, when your operation is responsible.
- Before the freight starts toward the truck, or after it reaches the place of final delivery: CGL, because the auto forms exclude that handling and the CGL definition does not reach it.
Is a yard tractor an auto?
It depends on where it runs and how it is registered. Under the CGL form, a vehicle maintained for use solely on or next to premises you own or rent is mobile equipment, which CGL covers. But a land vehicle subject to a compulsory or financial responsibility law or other motor vehicle insurance law where it is licensed or garaged counts as an auto. Tell your agent where each spotter runs so it lands on the right policy.
What doesn't CGL cover for a trucking company?
CGL doesn't cover your trucks in use, the freight you haul, your own employees, or your own property. Each of those needs its own coverage.
| Exposure | CGL exclusion | Coverage it usually needs |
|---|---|---|
| Crashes and other use of your trucks | Aircraft, auto or watercraft | Auto liability |
| Freight in your possession | Damage to property: personal property in your care, custody, or control | Motor truck cargo |
| Injury to your employees | Workers' compensation; employer's liability | Workers' compensation and employer's liability |
| Damage to your trucks, trailers, or building | Damage to property: property you own, rent, or occupy | Physical damage and property insurance |
| Spills and releases | Pollution | Pollution coverage arranged specifically |
The cargo gap catches carriers because two policies step away from it at once. CGL excludes personal property in your care, custody, or control, and the ISO auto forms exclude property owned or transported by the insured. If a load is damaged, our guide to documenting damaged cargo covers the evidence to collect.
Do trucking companies need liquor liability insurance?
Most carriers are not the target of the CGL liquor exclusion. It applies only if you are "in the business of manufacturing, distributing, selling, serving or furnishing alcoholic beverages."
The form does not define "distributing," though. If you haul beer, wine, or spirits for a brewer or distributor, ask your insurer to confirm in writing how it reads that word for your operation.
Which policy pays? Common trucking claims
The facts of the claim decide the policy, not the address. Here is how common trucking claims usually split under the standard ISO forms.
| What happened | Usually responds | Why |
|---|---|---|
| A visitor slips at your terminal office | CGL | Premises injury with no auto involved |
| Your forklift operator drops a pallet on a shipper's worker | CGL | A forklift not attached to the truck is not loading or unloading |
| Your truck's liftgate injures a receiver's employee | Auto liability | The device is attached to the covered auto |
| Your driver damages a receiver's doorway with a hand truck on the way in | Auto liability | Moving freight from the auto to final delivery is loading or unloading |
| Your truck backs into a customer's dock door | Auto liability | Operation of the auto |
| The pallet that fell was the customer's freight | Motor truck cargo | CGL and auto both exclude property in your care or that you transport |
| Your website makes a false claim about a competitor | CGL | Coverage B, personal and advertising injury |
The close calls turn on facts. Record what moved the freight, who operated it, and where the load was at the moment of the loss.
How much general liability does a trucking company need?
As much as your contracts require, and enough for your own exposure. FMCSA's minimums, such as $750,000 for for-hire general freight in vehicles of 10,001 pounds or more, apply to public liability for motor vehicles on public highways, which is your auto policy, not your CGL.
Contract minimums are specific. Amazon Relay, for example, requires commercial general liability of at least $1,000,000 per occurrence and $2,000,000 in the aggregate, alongside auto liability, cargo, workers' compensation, and employer liability. Our Amazon Relay requirements guide covers the rest.
How CGL limits work
- Each occurrence: the most paid for bodily injury, property damage, and medical payments from any one occurrence.
- General aggregate: the most paid in total under Coverages A, B, and C, except products and completed operations.
- Personal and advertising injury: the most paid under Coverage B to any one person or organization.
- Damage to premises rented to you and medical expense: smaller limits inside the occurrence limit.
When a contract asks for more than a primary policy provides, an umbrella or excess policy can sit over auto liability, general liability, and employer's liability. For what drives the price of the auto side, see how much commercial truck insurance costs.
What is the GL class code for truckers?
Class code 99793, Truckers, is the ISO general liability classification for trucking operations. An Amwins transportation underwriter's presentation to Ohio insurance agents notes that most trucking insurers are looking to write only that class.
So if you also warehouse, cross-dock, or repair other people's trucks, describe those operations in your submission rather than assuming the trucking class covers them.
What do shipper and broker contracts ask of your CGL?
Contracts can ask for three endorsements, and each does something narrower than its name suggests.
- Additional insured (ISO CG 20 26): adds the named organization as an insured, but only for injury or damage caused, in whole or in part, by your acts or omissions in your ongoing operations or in connection with your premises. It never increases your limits.
- Primary and noncontributory (ISO CG 20 01): your policy pays first without seeking contribution from the additional insured's own policy, but only if the additional insured is a named insured on that policy and you agreed to it in a written contract.
- Waiver of subrogation (ISO CG 24 04): your insurer gives up its right to recover from the organization named in the schedule, for payments arising out of your ongoing operations or work done under a contract with them.
The endorsement is the coverage; the certificate is not. The standard ACORD 25 certificate states that it "confers no rights upon the certificate holder," and that if the holder is an additional insured, the policy must be endorsed.
What about owner-operators leased to a carrier?
Read your lease and any facility agreements for a CGL requirement of your own, and match each certificate to a real endorsement. CGL covers your business, not your truck: if you run under another carrier's authority, non-trucking liability is the coverage for the truck when it is not under dispatch.
How Simplex helps you fit CGL to your trucking operation
General liability works when it fits with your auto and cargo coverage and with your contracts. We look at the operation first, then the policies.
General liability placed with the rest
As a broker, we quote and place commercial truck insurance, including general liability alongside auto liability, cargo, and physical damage, and a licensed agent follows up.
Owner-operators under another authority
If you are leased to a carrier, our non-trucking liability coverage is built for the time your truck is not under dispatch.
The compliance behind the policy
Our DOT safety compliance team keeps the records underwriters look at in order, from driver qualification files to ELD and hours of service.
