How much does semi-truck insurance cost for a new authority?

Federal minimum liability requirements

The Federal Motor Carrier Safety Administration sets minimum levels of financial responsibility in 49 CFR Part 387. These are minimums; many brokers and shippers require more.

Typical premiums

Progressive Commercial’s 2025 figures for new for-hire truck policies are the best public benchmark: about $926 a month for transport truckers (general freight and auto haulers) and $734 a month for specialty truckers such as garbage, septic and logging. Progressive cautions that these are averages and your rate depends on coverage needs, driving history, the type of trucking, radius and inspection history.

At the industry level, the American Transportation Research Institute’s 2026 operational cost analysis put liability and cargo insurance premiums at about $0.11 per mile in 2025, up 3.9% from the prior year. ATRI also noted that commercial auto insurance has been unprofitable for the industry in all but one of the last ten years, partly due to rising crash costs and litigation — a key reason trucking premiums keep climbing.

Why new authorities pay more

Insurers price on experience. A new authority has no loss or inspection history under its own USDOT number, so underwriters lean on the driver’s experience and record. FMCSA treats new carriers as New Entrants for 18 months and conducts a safety audit within the first 12 months of operation, and the inspection and audit record built in that period follows you into renewals.

Progressive notes that leasing onto a motor carrier is usually cheaper, because the motor carrier typically covers primary liability while you are under dispatch. That is why many drivers build a clean record leased on before getting their own authority.

The coverages a new authority typically buys

A trucking package is usually several coverages:

• Primary auto liability: the federally required coverage for injuries and damage to others. Your insurer files proof with FMCSA before your authority becomes active.
• Motor truck cargo: damage to or loss of the freight you haul. Brokers and shippers commonly set their own minimum cargo limits.
• Physical damage: collision and comprehensive for your tractor and trailer, usually required if the truck is financed.
• Non-trucking or bobtail liability: for leased-on drivers when operating outside dispatch.
• Trailer interchange, general liability and occupational accident coverage, depending on contracts and your setup.

How to keep trucking insurance costs down

Experience, a clean motor vehicle record and clean roadside inspections matter more than anything else. Beyond that:

• Start with a realistic plan for radius and commodities; high-value, hazardous or refrigerated loads cost more to insure.
• Choose a reliable, well-maintained truck and keep maintenance records — inspection violations hurt renewals.
• Consider leasing on until you have a few years of clean experience.
• Use ELDs and dash cameras, which help in claims and may help with some insurers.
• Hire drivers carefully; drivers with limited experience or violations can be hard to insure.
• Shop several trucking insurers before your authority activates, since appetite for new ventures varies widely.
