National context — Semi-Truck insurance overview
Semi-truck insurance is the full primary commercial-auto + cargo + physical-damage stack for a Class 8 tractor — what an owner-operator under their own DOT authority carries, or what a motor carrier provides for a leased driver under dispatch. It's the umbrella product that includes (or sits alongside) Bobtail, Non-Trucking Liability, Motor Truck Cargo, and MCS-90 filings.
Pricing reflects regulatory floor + real-world risk: typically $9,000-$15,000/year per power unit for a small interstate operation, sometimes up to $20,000+ for new authority or high-radius operators (Progressive Commercial, 2024).
