State minimums for commercial auto vary by vehicle type and state, but most businesses operating commercial vehicles need at least $300,000 to $1 million in liability coverage once contract requirements are factored in.
Start with your vehicle type and state minimums, adjust for contract requirements and fleet risk, then pressure-test against a realistic worst-case accident scenario.

Commercial auto coverage is built from several components, each with its own limit controlling what your insurer pays when a specific claim type hits. The three decisions that matter most are your BI/PD liability limits (or a CSL that replaces them), physical damage coverage on your vehicles, and UM/UIM. A rear-end collision triggers your BI and PD limits to pay the other driver's medical bills and vehicle repairs; a stolen fleet van triggers physical damage; an uninsured driver who hits your truck triggers UM/UIM to cover your driver's injuries and your vehicle repair costs.
Use the table below as a starting point, then adjust for your vehicle type, contract requirements and the accident scenarios your fleet is most likely to see.
Bodily Injury (BI) per Person | Cap on payouts for one person injured in an at-fault accident | $100,000–$500,000 per person |
Bodily Injury (BI) per Accident | Cap on total BI payouts across all injured people in one accident | $300,000–$1,000,000 per accident |
Property Damage (PD) per Accident | Cap on payouts for property damaged in an at-fault accident | $100,000–$500,000 per accident |
Combined Single Limit (CSL) | One unified cap covering both BI and PD per accident, replaces split limits | $500,000–$1,000,000 |
Medical Payments (MedPay) | Per-person cap on immediate medical bills for your vehicle's occupants, regardless of fault | $1,000–$5,000 per person |
Physical Damage (Comp/Collision) | Covers damage to or theft of your own commercial vehicle (required by lenders on financed vehicles) | Actual cash value (ACV) or stated value |
Uninsured/Underinsured Motorist (UM/UIM) | Covers your costs when an at-fault driver who hits you has no insurance or not enough | Match your BI limits |
Vehicle type creates the baseline for limit recommendations because it determines collision frequency, how many people are exposed per trip, and how severe property damage claims become on contact. Light-use vehicles like sedans and SUVs start lower; high-exposure vehicles like taxis, limousines and passenger vans require higher CSL because a single at-fault accident generates simultaneous BI claims across all occupants.
Select your vehicle type below to see recommended coverage amounts, situations that push you toward higher limits and add-ons that clients, lenders or state regulators commonly require.
Your commercial auto limit needs come down to six factors that either push your per-accident exposure up or leave room to start lower.
Vehicle type is the single largest pricing driver in commercial auto. A limousine averaging $870 per month nationally carries fundamentally different BI exposure than a sedan averaging $110 per month, per MoneyGeek's 2026 data. The vehicle type determines collision frequency, how many people are exposed per trip and the severity of property damage when contact occurs.
More miles driven means more exposure per year. A local delivery van making 50 stops in a five-mile radius accumulates different accident probability than an interstate freight van logging 80,000 miles annually. Long-haul and interstate operations also trigger FMCSA requirements that push minimum coverage above state baselines.
Each driver on a CA policy is an exposure unit. A fleet with five drivers (two clean records, two with minor violations, one with a prior at-fault accident) carries more cumulative risk than a same-size fleet with five clean records. Driver records directly affect both pricing at renewal and how likely a claim is to hit during the policy year.
Client contracts, freight broker agreements, GC sub-requirements and vehicle lender agreements set coverage minimums independently of what your vehicle type alone would suggest. A cleaning company using a cargo van might otherwise carry $500,000 CSL, but a corporate client requiring $1,000,000 CSL for all vendors sets the floor regardless. Review every active contract before choosing limits.
More vehicles mean more exposure units and more combined annual mileage. A single-vehicle operation has one chance per year for a claim; a 20-vehicle fleet has 20. Fleet size also affects aggregate UM/UIM exposure, and multiple uninsured driver accidents in one year hit the same policy repeatedly.
Your ability to pay out of pocket for costs above your limits affects how much coverage to carry. Businesses with strong cash reserves can absorb the gap between $500,000 and $1,000,000 CSL. Operations with tight cash flow benefit from higher limits that reimburse costs from one large at-fault accident before the bill reaches operating capital.
Choosing the right commercial auto limits comes down to balancing three things: what your contracts and state law require, what your vehicle and driver exposure actually looks like, and what you can absorb out of pocket if a claim exceeds your policy.
These four steps size coverage to your specific situation, not just what's common for your vehicle type.
Pull every contract, freight broker agreement, vehicle lease, client service agreement and your state's minimum liability requirement before comparing quotes. You're looking for two things: minimum CA limits (such as "$1,000,000 CSL per vehicle") and required endorsements (such as "additional insured" or "waiver of subrogation"). Contract minimums set the floor. State minimums set the legal floor. Both apply. Use whichever is higher. Write both down before requesting quotes.
State minimums for commercial vehicles vary by state. Confirm your state's specific requirements with your state Department of Insurance or a licensed agent before setting limits.
Put your operation in one of three tiers based on vehicle type, daily mileage and how many people are exposed per trip:
If contracts from Step 1 require higher limits than your tier suggests, use the contract number as your floor.
Run two worst-reasonable-day scenarios against your starting limit:
Stick to scenarios that could realistically happen in your operation. If your limit can't hold on a bad-but-plausible day, it's too low.
BI/PD limits cover costs for others when your fleet is at fault. UM/UIM and physical damage cover your costs when the other party is at fault or uninsured. Set UM/UIM limits to match your BI limits. A mismatch ($1,000,000 BI but $100,000 UM/UIM) leaves a large gap when an uninsured driver causes a serious accident with one of your vehicles.
Carry physical damage (comprehensive and collision) on every financed, leased or high-value vehicle you can't afford to replace out of pocket. Adding physical damage moves most vehicles from minimum coverage ($163 per month national average) toward mid-level coverage ($234 per month), based on MoneyGeek's 2026 data.
Commercial auto limits aren't one-size-fits-all across vehicle types. A sedan operation at $300,000 CSL and a limousine fleet at $1,500,000 CSL are both making the right call for their exposure. Get your regulatory and contract floors in place first, then run the pressure-test from Step 3 against your actual vehicle type and driver pool. If the worst plausible accident in your operation can beat your per-accident limit, your CSL is too low.
If you need quick answers about commercial auto coverage limits, here are the essentials:
Starting limits depend on vehicle type. Light-use vehicles (sedans, SUVs) start at $300,000 CSL. Higher-exposure vehicles (vans, pickup trucks, food trucks) start at $500,000 to $1,000,000 CSL. Taxis and limousines typically need $1,000,000 CSL or more to meet state livery regulations. Your contracts may require specific minimums regardless of vehicle type.
Vehicle type is the primary driver. A limousine ($870 per month nationally) carries the highest per-accident BI exposure of any vehicle type; a sedan ($110 per month) carries the lowest, per MoneyGeek's 2026 data. Annual mileage, number of drivers, MVR history and contract requirements all push limits up or down from the vehicle-type baseline.
Yes. Client contracts, freight broker agreements, GC sub-requirements and vehicle lender agreements set minimum required limits and endorsements. Review every active agreement before choosing coverage. Written obligations apply regardless of what your vehicle type alone would suggest.
Run a worst-case accident scenario: if your driver causes a multi-vehicle collision injuring multiple people, could combined BI, PD and legal defense costs exceed your per-accident limit? If yes, move up a tier. Passenger-carrying vehicles (vans, taxis, limousines) need to stress-test against multi-occupant BI scenarios specifically.
Get quotes with your chosen limits and any required add-ons (additional insured, waiver of subrogation, HNOA for personal vehicle use). Compare how different CSL levels affect your premium. Progressive Commercial ($143 per month, $1,713 per year) and GEICO ($149 per month, $1,785 per year) rank first and second overall for commercial auto, per MoneyGeek's 2026 analysis.
