Semi truck insurance costs about $750 to $1,200 a month for an owner-operator with three or more years under their own authority, and about $1,000 to $1,700 a month for a new authority. That's roughly $9,000 to $14,000 a year established and $12,000 to $20,000+ in the first year. An owner-operator leased on to a carrier pays far less, often $250 to $420 a month.
Semi Truck Insurance Cost By Operating Status
| Operating Status | Typical Monthly Cost | Typical Annual Cost |
|---|---|---|
| Own authority, 3+ years, clean record | $750–$1,170 | $9,000–$14,000 |
| Own authority, first year | $1,000–$1,700+ | $12,000–$20,000+ |
| Leased on to a carrier | $250–$420 | $3,000–$5,000 |

What You Pay For, Coverage By Coverage
| Coverage | Typical Annual Cost |
|---|---|
| Primary auto liability | $5,000–$10,000+ |
| Physical damage (about 2%–3% of truck value) | $1,000–$3,000 |
| Motor truck cargo | $400–$1,800 |
| Occupational accident | $1,600–$2,200 |
| General liability | $500–$800 |
| Bobtail or non-trucking liability (leased on) | $350–$480 |
Primary liability is usually 55% to 70% of the total. Leased-on drivers skip primary liability and cargo because the carrier provides them, which is why their total is so much lower.
Semi Truck Insurance Cost By State
Where your truck is based can change your premium more than almost anything else. One 2026 rate study put local premiums at about $296 a month in Mississippi and about $1,730 a month in New Jersey. New Jersey, Louisiana, Delaware, New York and Connecticut were the most expensive states in that study. Interstate long-haul operators typically pay 30% to 50% more than those local benchmarks.
What Else Drives The Price
- Authority age. New authorities pay the most. Rates typically fall 15% to 25% after the first year and keep improving through year three.
- Freight. Dry van is the baseline. Reefer and flatbed usually cost 15% to 25% more, and hazmat requires up to $5,000,000 in liability.
- Driving record and CSA scores. Violations and at-fault accidents raise every line on the quote.
- Truck age and safety equipment. Newer trucks with collision mitigation and dash cams can earn discounts.
- Payment plan. Monthly installments can cost noticeably more over a year than paying in full.
Example: First-Year Dry Van Authority
A new owner-operator running a dry van regionally from a mid-cost state, with $1,000,000 liability, $100,000 cargo and physical damage on a financed tractor and trailer, should budget about $1,200 to $1,700 a month in year one. With a clean first year, the same operation can often renew 15% to 25% lower.
Why Semi Truck Insurance Keeps Rising
The American Transportation Research Institute measured trucking insurance at a record $0.102 per mile in 2024. Large jury verdicts in truck accident cases push liability rates up for every carrier, including those with spotless records.

Frequently Asked Questions
How Much Is Semi Truck Insurance Per Month?
Established owner-operators under their own authority typically pay about $750 to $1,200 a month. New authorities usually pay about $1,000 to $1,700, and leased-on drivers about $250 to $420.
Why Is Semi Truck Insurance So Expensive?
Primary liability is expensive because truck accidents can produce very large verdicts. New authorities, high-cost states and specialized freight add more on top.
Is Semi Truck Insurance Cheaper If I'm Leased On?
Yes. When you're leased on, the carrier provides primary liability and cargo, so you usually only need bobtail or non-trucking liability, physical damage and occupational accident.
