What Does CGL Insurance Cover for Trucking Businesses?

What It Covers and How It Works a CGL for Truckers

If you run trucks for a living, you deal with risk every day, at a shipper’s dock, even in your own office when a vendor trips on a cord. Commercial General Liability (CGL) exists to protect your business against third-party claims that aren’t caused by operating your truck on the road. CGL typically covers:

• Bodily Injury (BI): A visitor slips at your office or a vendor gets hurt while you’re loading on your premises.
• Property Damage (PD): You accidentally damage someone else’s property during your operations (not while driving on public roads).
• Personal & Advertising Injury: Libel/slander in your ads or website, use of a slogan that triggers a claim, etc.
• Defense Costs: Your insurer hires lawyers and defends you, even if the claim is groundless, up to policy limits and subject to terms.

Two policy flavors matter:

• Occurrence: The policy that was active when the incident happened responds, even if the claim is filed later.
• Claims-made: The policy that’s active when the claim is made responds.

At Simplex with our day-to-day working with fleets and owner-operators for more than 20 years, we’ve learned that most confusion isn’t about what CGL is, but about what CGL isn’t—especially where it overlaps with Commercial Auto and Motor Truck Cargo. Let’s clear that up.

Whenever we onboard a carrier, we map how CGL interacts with Auto and Cargo across real claim paths (yard → dock → road → delivery). That alone has saved clients from costly gaps.

What CGL Doesn’t Cover for Truckers

CGL is not your “everything policy.” Typical limitations include:

• Autos on public roads: If the truck is moving under its own power on a public roadway and causes BI/PD, that’s Commercial Auto Liability, not CGL.
• Damage to cargo in your care, custody, or control: That’s Motor Truck Cargo, CGL doesn’t pay when freight itself is damaged under your control.
• Employee injuries: Usually Workers’ Compensation (or Occupational Accident for certain O/Os).
• Intentional acts and expected injuries: If you meant to do it, CGL won’t.
• Professional/contractual liabilities beyond what CGL’s contractual liability covers; read your contracts carefully.
• Pollution (often limited) and certain liquor liability scenarios unless specifically endorsed.
• Damage to your own property or your truck/trailer: that’s Physical Damage coverage.

CGL vs Commercial Auto Liability: Which Policy Responds to What?

Think “operations” vs “on-road.”

• CGL covers incidents emerging from your premises and operations not tied to driving on public roads. Example: A vendor is injured at your terminal; or you accidentally damage a customer’s fence while staging a trailer in their private yard (context-dependent).
• Commercial Auto Liability covers on-road BI/PD due to ownership, maintenance, or use of a covered auto. Example: Trailer swing damages a forklift during a maneuver in a traffic area, often Auto responds.

Fast test we use internally: If wheels are rolling on public roads or it’s clearly “use of an auto,” think Auto Liability. If it’s a premises/operations slip-and-fall or non-auto operation risk, think CGL.

CGL vs Motor Truck Cargo: Protecting Freight vs Third-Party Damages

• CGL: protects you against claims from third parties for BI/PD/personal-advertising injury.
• Cargo: protects the cargo you transport against direct physical loss while it’s in your care, custody, or control.

Scenario examples:

• Pallets fall and injure a customer’s employee at the dock: potential CGL (BI), subject to terms.
• Those pallets crush the shipment itself: that’s Cargo, not CGL.
• You scratch a shipper’s metal door while backing into the dock: could be CGL (PD) or Auto depending on whether it stems from the “use of auto.” Documentation matters.

Does General Liability Cover Loading & Unloading? 

It depends on policy wording and on whether the incident is tied to “use of an auto.” Typical patterns we see:

• Loading with a forklift at your premises causing injury to a visitor: frequently CGL exposure.
• Damage during loading/unloading while the truck is being used and the mechanism involves the auto (e.g., liftgate operation): may pivot to Auto Liability.
• Damage to the cargo during loading/unloading: that’s Cargo, not CGL.

Pro tip from the field: Clarify who controls the dock and who’s listed as Additional Insured in contracts. Many broker/shipper agreements push risk downstream; having the right AI/PNC/Waiver endorsements streamlines claims handling.

How Much General Liability Do I Need for My Trucking Operation?

Typical starting points we see in trucking:

• $1,000,000 each occurrence / $2,000,000 general aggregate is a common baseline for many small carriers.
• Contracts with national shippers or large 3PLs may require higher limits and specific endorsements.
• If you haul specialized or high-risk loads, consider Umbrella/Excess for additional protection over both CGL and Auto.

What we do each year: an annual insurance review. Operations change—new lanes, new facilities, different shipper contracts. We reassess revenue, radius, driver count, loss runs, and contractual obligations and right-size limits accordingly.

CGL for Owner-Operators: Requirements, Certificates, and Contract Clauses

If you’re an owner-operator leased onto a motor carrier, your contract may still require your own CGL (and always review COIs carefully).

• Keep a clean Certificate of Insurance (COI) list: who needs to be Additional Insured, where to send certificates, renewal dates.
• Watch for Primary & Non-Contributory wording and Waiver of Subrogation—common in broker/shipper templates.
• Confirm whether the carrier’s policy satisfies venue-specific requirements (ports, rail yards) or if you need your own premises GL for a small yard/office.

Average Cost of CGL for Truckers

CGL pricing depends on gross receipts/payroll, operations type, territory, loss history, and required endorsements. In practice, we see premiums move with:

• Revenue growth (rating basis),
• Operations (yard, warehousing, cross-docking),
• Loss runs (frequency/severity),
• Contractual endorsements (AI/PNC/Waiver can add cost),
• Safety culture (documented training = better underwriter appetite).

Cost-control moves we regularly implement:

• Provide clean, complete submissions (driver/terminal profiles, safety manuals, photos).
• Show training logs (forklift/dock safety).
• Review endorsements—a narrowly tailored AI can cost less than blanket AI, depending on need.
• Package policies (GL + Auto + Cargo + Umbrella) with strong carriers to unlock credits.

Beyond General Liability: Other Insurance Trucking Companies Actually Need

• Commercial Auto Liability: Your primary auto liability for on-road BI/PD.
• Motor Truck Cargo: Protects cargo in your care, custody, or control.
• Workers’ Compensation / Occupational Accident: Employee/driver injuries.
• Umbrella/Excess: Extra limits over Auto, GL 
• Commercial Property/Business Interruption: If you own/lease facilities.
• Equipment Physical Damage: Your tractors/trailers.
• Cyber/E&O (select cases): If you handle sensitive data or provide dispatch/planning services that could trigger negligence claims.

Steps to Get a CGL Quote the Smart Way

Here’s our fast-track checklist for a smooth, accurate quote:

1. MC/DOT details and operations description (lanes, commodities, yards, warehousing).
2. Gross receipts/payroll (rating basis) and headcount.
3. Loss runs (3–5 years)—we help you requestlos
4. Driver list & training logs (dock/forklift) to show safety discipline.
5. Facility info (addresses, square footage, security, photos).
6. Contracts (shipper/broker templates) to match AI/PNC/Waiver requirements.
7. Desired limits (start at $1M/$2M and adjust) and note if you need Umbrella.
8. Certificate holders list and any special wording deadlines.
