Primary liability insurance is the foundational coverage that every for-hire motor carrier is legally required to carry. It pays for bodily injury and property damage you cause to other people in an accident while operating your commercial truck. Without it, you cannot legally move freight on public roads in the United States β and no broker, shipper, or freight network will dispatch you without proof of it.
For owner-operators, fleet operators, and anyone holding an active FMCSA operating authority (MC number), primary liability is non-negotiable. It protects the injured party in an accident β not your truck or cargo β covering medical bills, legal defense costs, and settlements if you are found at fault. It is the first line of financial protection between your business and a potentially company-ending lawsuit.
According to Nazar Mamaev, trucking insurance specialist at Full Coverage LLC, “Primary liability is the one coverage you absolutely cannot skimp on. We’ve seen single accidents produce $500,000 to $1 million in third-party claims. Carriers writing trucking policies know this β which is why minimum FMCSA limits exist and why underwriters scrutinize your driving history so carefully.”
What Does Primary Liability Insurance Cover?
Primary liability insurance covers damages and injuries you cause to third parties while operating your commercial truck in the course of for-hire transportation. Here is a detailed breakdown of what is included and what is not.
What Is Covered
- Third-party bodily injury: Medical expenses, hospitalization, rehabilitation, lost wages, and pain and suffering for people injured in an accident you caused β including other drivers, passengers, and pedestrians.
- Third-party property damage: Repair or replacement costs for other vehicles, buildings, fences, infrastructure, and any other property damaged in an accident.
- Legal defense costs: Attorney fees, court costs, and settlement costs if a lawsuit is filed against you as a result of an accident.
- Death benefits: Compensation to survivors if a third party is killed in an accident for which you are liable.
What Is NOT Covered
- Your own truck: Damage to your own vehicle is covered under physical damage insurance (comprehensive and collision), not primary liability.
- Your cargo: Freight you are hauling is covered by motor truck cargo insurance, not primary liability.
- Your own injuries: Your medical bills if you are hurt in an accident are covered by occupational accident insurance or workers’ compensation, not primary liability.
- Non-trucking use: If you drive your truck for personal use outside of dispatched loads, you need bobtail or non-trucking liability coverage for that period.
- Pollution or hazmat: Environmental cleanup from cargo spills typically requires separate pollution liability endorsements.
Who Is Required to Have Primary Liability Insurance?
FMCSA Requirements
The Federal Motor Carrier Safety Administration (FMCSA) mandates minimum primary liability limits for all interstate for-hire motor carriers. These minimums are set by cargo type and vehicle weight:
- $750,000 β For-hire carriers hauling general (non-hazardous) freight in vehicles 10,001 lbs or more GVWR
- $1,000,000 β For-hire carriers hauling oil (non-hazardous)
- $5,000,000 β Carriers hauling hazardous materials (certain categories)
- $300,000 β For-hire carriers in vehicles under 10,001 lbs GVWR (non-hazardous)
In practice, most brokers and shippers require a minimum of $1,000,000 per occurrence regardless of FMCSA minimums. If you plan to haul for major freight brokers, expect to need at least $1M in primary liability coverage.
State Requirements
States may impose additional requirements on intrastate carriers (hauling within state lines only). Indiana, for example, follows FMCSA minimums for most carriers but has its own regulations for certain intrastate operations. Always confirm your state’s specific requirements with a licensed insurance agent familiar with commercial trucking in your state.
Lender and Lease Requirements
If you are financing or leasing your truck, your lender will require proof of primary liability (along with physical damage coverage) before releasing the vehicle. Lease agreements with motor carriers may also specify minimum liability limits that exceed FMCSA requirements.
How Much Does Primary Liability Insurance Cost?
Primary liability is typically the most expensive component of a trucking insurance package. In our book of business at Full Coverage LLC, owner-operators with a new authority in Indiana paid an average of $7,500β$12,000 per year for primary liability alone in 2025. Experienced operators with clean records and 2+ years of operating history often pay $5,000β$9,000 per year.
| Driver/Operation Profile | Typical Annual Premium |
|---|---|
| New authority (under 12 months), general freight | $8,500β$12,000 |
| Experienced operator (2+ years), clean record | $5,000β$9,000 |
| Operator with violations or accidents | $10,000β$18,000+ |
| Hazmat carrier | $12,000β$25,000+ |
| Long-haul flatbed (higher risk cargo) | $7,500β$13,000 |
Factors That Affect Your Primary Liability Premium
- Years of operating authority: New authorities pay significantly more. Most carriers see rate relief after 12β18 months of clean operation.
- Driving and loss history: Accidents, violations, and prior claims are the biggest premium drivers. Even one at-fault accident can double your premium.
- Cargo type: Hazmat, auto hauling, and flatbed loads are rated higher than standard dry van freight.
- Operating radius: Long-haul coast-to-coast operations face higher premiums than regional or local runs.
- Number of power units: More trucks means more premium, though fleet discounts apply at scale.
- Driver age and CDL experience: Drivers under 25 or with less than 2 years’ CDL experience are rated higher by most carriers.
- Credit score (in some states): Personal or business credit can affect commercial auto rates depending on state law.
How to Lower Your Primary Liability Premium
- Maintain a clean driving record β even one preventable accident is costly for 3β5 years.
- Work with a broker who shops multiple carriers; rates can vary by $2,000β$4,000/year for the same operation.
- Install dash cameras β many carriers offer 5β15% discounts for documented dash cam programs.
- Complete a certified safety training program (defensive driving, Smith System, etc.).
- Choose a higher deductible if your cash flow allows; this lowers premium on some policy structures.
- Keep your FMCSA safety score clean β CSA violations raise flags with underwriters.
Primary Liability vs. General Liability: What’s the Difference?
Primary liability and general liability are two separate coverages that trucking companies often confuse. Here is the key distinction:
| Coverage | What It Covers | When It Applies |
|---|---|---|
| Primary Liability | Bodily injury and property damage to third parties caused by your truck while operating | On-road accidents while dispatched |
| General Liability | Premises liability, completed operations, personal injury, advertising injury | Off-road incidents β at a customer’s dock, at your yard, during loading/unloading |
Many brokers and shippers require both. General liability protects against claims like damaging a shipper’s warehouse door while backing in, or someone slipping and falling at your business location. Primary liability only applies while the truck is in motion and actively operating in for-hire service.

Frequently Asked Questions About Primary Liability Insurance
What is the minimum primary liability insurance required by FMCSA?
The FMCSA requires a minimum of $750,000 in primary liability for for-hire carriers hauling general (non-hazardous) freight in vehicles over 10,001 lbs GVWR. However, most freight brokers require $1,000,000 per occurrence, and hazmat carriers must carry $1,000,000 to $5,000,000 depending on the material type.
Does primary liability cover me if the accident is my fault?
Yes β primary liability specifically covers third-party claims when you are at fault. It pays for the other driver’s medical bills, vehicle repairs, and legal costs. It does not cover damage to your own truck or your own injuries; those require physical damage insurance and occupational accident coverage, respectively.
Can I get primary liability insurance with a new authority?
Yes. New authorities can absolutely get primary liability insurance. You will pay more than an experienced operator β typically $2,000β$4,000 higher per year β but there are carriers that specialize in new authority business. Full Coverage LLC has access to multiple markets that write new authorities, and we can usually bind coverage within 24β48 hours of receiving your application.
What happens if I drive without primary liability insurance?
Operating without the FMCSA-required minimum primary liability is a federal violation. Your operating authority can be revoked, you face significant fines, and β most importantly β any accident creates unlimited personal financial exposure. The financial consequences of an uninsured commercial truck accident can be catastrophic and business-ending.
Does primary liability cover all drivers on my policy?
Your policy covers listed and permissive drivers operating your scheduled vehicles. Each driver on your policy is underwritten individually β their MVR, CDL history, and violation record all affect your premium. Always notify your agent when you add or remove drivers to ensure you’re not operating with an unlisted driver who creates a potential coverage gap.
