The Federal Motor Carrier Safety Administration (FMCSA) requires all trucking companies to carry Primary Liability Insurance before operating legally. These requirements are designed to ensure that motor carriers have the financial ability to cover bodily injury and property damage caused by their commercial vehicles.
Without meeting these liability requirements, your authority will not become active, and you cannot haul freight for hire.
The FMCSA sets minimum liability limits based on the type of freight you haul and the weight of your vehicle. These limits represent the minimum amount of coverage required to operate legally.
Most trucking companies choose $1 million in coverage because it satisfies nearly all broker and shipper requirements, even though the FMCSA minimum is lower.
The FMCSA’s liability rules are designed to protect the public. When a commercial vehicle is involved in an accident, the damages can be severe. Primary Liability Insurance ensures that injured parties and damaged property are covered.
These requirements do not protect your truck, your cargo, or your business assets. They exist solely to protect the public.
Once you purchase Primary Liability Insurance, your insurance company must file a BMC-91X with the FMCSA. This filing proves that you have the required liability coverage.
Your authority will remain in a pending status until the FMCSA receives and processes this filing.
After your insurer submits the BMC-91X, the FMCSA typically activates your authority within 24–72 hours. However, delays can occur if there are errors in your application or if the filing is incomplete.
Ensuring your application and insurance details are accurate helps speed up the activation process.
Any motor carrier operating a commercial vehicle for hire across state lines must comply with FMCSA liability rules. This includes owner-operators, small fleets, and large carriers.
Even intrastate carriers may be subject to similar requirements depending on state regulations.
Although the FMCSA minimum for general freight is $750,000, most brokers and shippers require at least $1 million in liability coverage. This is because higher limits reduce their financial exposure in the event of a major accident.
Carriers with only the FMCSA minimum may struggle to secure loads from reputable brokers.
Maintaining compliance is essential for keeping your authority active and avoiding penalties. Insurance lapses or cancellations can lead to immediate FMCSA action.
If your insurance is canceled, the FMCSA will revoke your authority until new coverage is filed.
FMCSA liability requirements are a critical part of operating a trucking business. Understanding the minimum coverage limits, the purpose of the BMC-91X filing, and the steps needed to stay compliant helps ensure your authority remains active and your business stays protected.
