What Is Freight Insurance? The Complete Guide for Carriers, Brokers & Shippers

What Is Freight Insurance — And Why Standard Carrier Liability Isn't Enough

Freight insurance covers the financial loss when cargo is damaged, lost, or destroyed in transit. It is distinct from carrier liability — and that distinction is the most important concept in transportation insurance. Every motor carrier operating in the US is subject to the Carmack Amendment, which establishes their baseline legal liability for cargo loss or damage. But Carmack liability has ceiling limits, exceptions for acts of God and shipper negligence, and valuation rules that reduce claims to depreciated value rather than replacement cost. The result: most shippers who rely on carrier liability alone discover its limitations only after a significant loss.

Freight insurance operates separately from and in addition to carrier liability. A cargo insurance policy covers the full declared value of the shipment, pays claims regardless of which party was at fault, and eliminates the burden of proving carrier negligence that Carmack-based claims require. For shippers moving high-value goods, the premium cost of cargo insurance — typically 0.1% to 0.5% of declared cargo value per shipment — is a fraction of the financial exposure of a single uninsured loss on a full truckload. For carriers, primary liability insurance is legally required to operate; the question is not whether to carry it but how much, what endorsements to add, and which provider offers the best combination of cost and coverage depth for their specific freight profile.

The freight insurance market is more segmented than it appears from the outside. Carriers, brokers, and shippers each need different coverage types designed for their specific role in the freight transaction — and the products designed for one role typically don't serve the others well. A carrier who buys cargo insurance designed for shippers may find it doesn't cover their common law liability for customer goods. A broker who buys a carrier's liability policy may find it doesn't cover the contingent cargo exposure they have when a carrier they hired causes a loss. Understanding which coverage type matches your role is the prerequisite to evaluating any specific provider.

Coverage Types by Role: What Carriers, Brokers, and Shippers Each Need

Freight insurance needs are determined by your operational role in the shipment — not by the cargo itself.

Carrier Coverage Requirements

Primary Liability Insurance is the foundational coverage required by the FMCSA for every motor carrier operating on US roads. The federal minimum is $750,000 for property freight and $5 million for hazardous materials — but actual market minimum is typically $1 million per occurrence for the coverage that shippers and brokers require. Primary liability covers bodily injury and property damage to third parties caused by the carrier's operations; it does not cover the carrier's own cargo or equipment.

Cargo Insurance covers the carrier's legal liability for loss or damage to customer freight in their care, custody, and control. Standard cargo coverage runs from $100,000 to $1 million per occurrence. High-value freight (electronics, pharmaceuticals, food-grade), trade lanes with high theft exposure, and customers with contractual insurance requirements drive the need for higher cargo limits.

Physical Damage covers repair or replacement of the carrier's own tractors and trailers. Lenders who finance equipment require physical damage coverage; owner-operators with paid-off equipment sometimes drop it to reduce premiums, accepting the risk of an uninsured equipment loss.

Occupational Accident or Workers Compensation covers driver injuries. Owner-operators classified as independent contractors typically use occupational accident policies. Carriers with W-2 employee drivers carry workers compensation in compliance with state law.

Broker / 3PL Coverage Requirements

Contingent Cargo Insurance is the primary freight coverage product for freight brokers. Brokers don't take physical possession of freight — they arrange transportation by hiring licensed motor carriers. When a carrier they hire damages or loses freight, the broker's legal exposure depends on whether their contract with the shipper includes cargo liability and whether the carrier's insurance responds. Contingent cargo policies pay claims when the underlying carrier coverage fails or is insufficient — providing a financial backstop that protects the broker's P&L and shipper relationships.

Errors & Omissions (E&O) Insurance covers professional liability claims alleging the broker made a mistake in arranging transportation — booking the wrong carrier, failing to verify a carrier's authority, errors in documentation, or missed pickup causing business interruption losses. E&O exposure has increased as broker contracts include more specific performance requirements and liability acceptance language.

General Liability covers bodily injury and property damage claims arising from the broker's business operations — slip-and-fall at the office, damage caused by an employee, etc. Required by most commercial landlords and enterprise shipper contracts.

Shipper Coverage Requirements

Cargo Insurance (Open Cargo Policy) covers the shipper's goods in transit under a single blanket policy that automatically covers all shipments rather than requiring a separate declaration per load. Open cargo policies are the standard product for shippers with regular freight volume — they provide full declared-value coverage for loss or damage regardless of which carrier moves the freight and without the burden of proving carrier negligence.

Per-Shipment / On-Demand Cargo Insurance covers individual shipments booked through platforms like Loadsure or InsureShield, typically as an add-on at the time of booking. Suited to shippers with irregular high-value shipments who don't generate enough volume for an open cargo policy or who need coverage for specific loads that exceed their open policy limits.

Trade Credit Insurance is relevant for shippers selling goods internationally who face the risk that the buyer won't pay after the goods are shipped — a different financial risk from physical cargo loss but one that affects supply chain cash flow.

Key Coverage Terms Every Freight Buyer Should Know

The Carmack Amendment: What It Covers and What It Doesn't

The Carmack Amendment (49 U.S.C. § 14706) is the federal law that governs carrier liability for cargo loss and damage. It establishes a strict liability standard for carriers — the shipper doesn't need to prove negligence, only loss or damage. But Carmack also limits carrier liability in ways that create significant gaps:

Valuation limits: Carriers can limit their liability per pound by publishing tariff rates (typically $0.50 to $2.00/lb depending on commodity). A 45,000-pound truckload of electronics at $1/lb carrier liability = $45,000 maximum claim. The actual cargo value might be $500,000. The gap is the shipper's uninsured loss.

Exceptions to liability: Carmack excuses carriers from liability for losses caused by: act of God (hurricanes, floods), act of the shipper (improper packaging), inherent vice of the goods (perishables that spoil), public enemy, and act of public authority. These exceptions are narrowly interpreted but represent real exposure.

Time limits on claims: Federal law gives shippers 9 months to file a claim and 2 years to bring suit after a carrier denies a claim. Missing these windows forfeits the shipper's rights entirely.

Cargo insurance eliminates these limitations: full declared value coverage, no per-pound caps, no negligence exceptions, and claims paid directly rather than through adversarial dispute with the carrier.

Freight Insurance Market Structure: Brokers vs. Direct Carriers vs. Embedded Insurance

The freight insurance market delivers coverage through three distribution models, each with different tradeoffs:

Insurance brokers and agents (Hub International, McGriff, Reliance Partners, Roanoke) represent multiple insurers and can shop your risk across carriers to find the best combination of coverage and price for your specific profile. Full-service transportation insurance brokers understand DOT compliance requirements, FMCSA filings, and the specialized endorsements (refrigerated cargo, hazmat, high-value goods) that standard commercial auto policies miss. For carriers with complex operations, the broker relationship provides ongoing risk management advice that direct-to-carrier purchases don't include.

Direct insurers (Progressive Commercial, Cover Whale, Travelers, Great West Casualty, Canal Insurance) underwrite and carry the risk themselves. Direct relationships can provide faster claims resolution because there's no intermediary in the claims chain. Large direct insurers like Progressive and Travelers have dedicated transportation underwriting and claims departments with deep industry expertise.

Embedded and API-driven insurance (Loadsure, InsureShield) delivers coverage at the point of freight booking through API integrations with TMS platforms, load boards, and logistics software. Per-shipment coverage priced and bound in under 60 seconds serves shippers and brokers who need spot coverage on specific loads rather than annual blanket policies. The Lloyd's of London market backing these embedded products provides financial strength behind the tech-forward delivery model.

How to Evaluate Freight Insurance Providers

1. Verify the AM Best Rating of the Underlying Insurer

For carriers: shippers and brokers often require that the insurer backing your primary liability policy carries an AM Best rating of A- or better. Great West Casualty and Canal Insurance carry AM Best A+ ratings. Progressive and Travelers carry AM Best A+ or A++ ratings. Verify the underlying insurer's rating, not just the broker's reputation.

2. Confirm Coverage Actually Matches Your Operation

The most common freight insurance mistake is buying a standard commercial auto policy without the endorsements that freight operations actually require. Refrigerated cargo haulers need reefer breakdown endorsements. Carriers hauling electronics need theft-specific riders for high-risk ZIP codes. Brokers need contingent cargo, not standard cargo coverage. Cross-border operations need US/Mexico coverage certificates. Review your current policy against your actual freight profile before renewal.

3. Evaluate Claims Handling Track Record, Not Just Price

Claims handling is where insurers differentiate at the moment it matters most. Insurers with dedicated transportation claims adjusters (Sentry's in-house adjusters, Progressive's 100% in-house claims staff) resolve claims faster than carriers that outsource to general adjusters unfamiliar with freight loss documentation requirements. Ask each provider for their average claim resolution time and whether they use in-house or outsourced adjusters before binding a policy.

4. Consider Telematics Discounts

ELD-equipped fleets with clean safety records can generate significant premium savings through telematics-linked programs. Progressive's Smart Haul program averages $1,261 in annual savings for participating fleets. Cover Whale's AI underwriting using telematics data offers up to 30% discounts for carriers with strong safety profiles. If your fleet runs telematics hardware, verify which insurers can access that data and how it affects pricing before purchasing at undiscounted rates.

5. For Brokers: Verify Contingent Cargo Limits Match Your Largest Shipment

Contingent cargo coverage limits should match the highest-value individual shipment you regularly arrange. A broker whose shipper customers move pharmaceutical loads at $500,000+ declared value needs contingent cargo limits that cover that exposure — standard $100,000 contingent cargo limits leave a broker personally exposed on high-value loads when the underlying carrier policy fails.
