Starting a new trucking company is exciting, but the insurance requirements can feel overwhelming. Primary Liability Insurance is the first, mandatory, and most expensive policy every new authority must secure before operating legally. Without it, the FMCSA will not activate your authority, and you cannot haul loads.
Primary Liability protects the public — not your truck — by covering bodily injury and property damage you may cause while operating a commercial vehicle.
The FMCSA requires all new motor carriers to carry a minimum level of liability coverage before their authority becomes active.
Most new authorities choose $1 million because it satisfies nearly all broker and shipper requirements.
Until your insurance company files the Form BMC‑91X, your authority will remain pending.
New trucking companies almost always pay higher rates during their first year. Insurers consider new authorities “higher risk” because they lack:
This means your first-year premium is based on unknown risk, not proven performance.
New authorities with clean driving records and a narrow radius typically see better pricing.

If you maintain a clean record, your second‑year renewal is often significantly lower.
Even in your first year, you can take steps to reduce your premium.
Drivers with no major violations, no recent accidents, and several years of CDL experience will dramatically improve your rate.
Long‑haul operations carry more risk. If possible, start with:
You can expand later once your safety record is established.
Your safety culture directly impacts your renewal pricing.
Small claims can hurt your loss history and increase your premium. When possible, handle minor repairs out of pocket.
Many new authorities misunderstand what this policy actually protects.
Primary Liability does not cover:
Those require separate policies such as:
Primary Liability is only one piece of a complete insurance package.
New authorities often face more documentation requirements. Insurers may request:
Underwriters use this information to determine your risk level and final pricing.
Once you bind coverage, your insurer files the BMC‑91X with the FMCSA. Activation typically takes:
Your authority will not go active until the FMCSA receives and processes the filing.
Primary Liability Insurance is the foundation of your trucking business. It’s required, it’s expensive, and it’s often confusing — but understanding how it works helps you:
This is the policy that gets your business on the road, keeps you compliant, and protects the public.
