If you drive a vehicle for business purposes whether it’s delivering goods, transporting passengers, or hauling equipment you’ll likely need commercial auto insurance. It’s not the same as personal car insurance, even if you’re driving the same vehicle. Commercial auto insurance offers special coverage for accidents or damages that occur while using a vehicle for business. On top of that, if your business operates trucks or commercial vehicles across state lines, you also have to meet requirements from the U.S. Department of Transportation (DOT).

Each state has its own rules about what kind of coverage businesses must carry. Whether you’re in California or Georgia, knowing the local laws and DOT rules can save you from costly fines and ensure your business stays on the road legally and safely. Let’s break it all down in simple terms.

What Is Commercial Auto Insurance?

Commercial auto insurance is a policy that covers vehicles used for business. It includes:

Liability Coverage: Pays if you or your driver causes an accident.

Collision Coverage: Covers repairs if your vehicle is damaged in a crash.

Comprehensive Coverage: Covers non-collision incidents like theft or weather damage.

Uninsured/Underinsured Motorist Coverage: Protects you if another driver doesn’t have enough insurance.

Medical Payments: Helps pay medical bills for you and your passengers.

This type of insurance is required by law for most business vehicles, especially if you transport goods or people or drive across state lines.

What Are DOT Requirements for Commercial Vehicles?

If you drive a commercial vehicle across state lines or carry certain types of cargo, the Federal Motor Carrier Safety Administration (FMCSA)—a branch of the DOT has rules you must follow. These include:

USDOT Number: A unique number used to monitor safety records. Required for most interstate commercial drivers.

Minimum Liability Insurance:

$750,000 for general freight

$1 million if transporting oil

$5 million if transporting hazardous materials

MCS-90 Endorsement: A form that proves you meet federal insurance requirements.

BOC-3 Form: Names a process agent in every state you do business in.

If you’re staying within one state, your insurance may still need to meet DOT standards if the state adopts federal rules. Always check both.
