Commercial Auto Insurance for Small Business
The vehicle that gets you sued is probably not the one on your policy
An employee takes her own car to pick up supplies. It is a five-minute errand she has run a hundred times. This time she runs a red light and puts someone in the hospital.
Her personal auto policy has a $50,000 limit and, depending on how the insurer reads the business-use provisions, may not respond at all. Your general liability policy excludes autos. Your commercial auto policy lists three company vans and does not list her Corolla. The plaintiff's attorney sues the business anyway, because the business is who she was working for and the business is where the money is.
This scenario has a name — non-owned auto liability — and the endorsement that covers it costs very little. Most small employers do not have it, because nobody sold it to them and because the risk sits in a vehicle they do not own, do not maintain, and never think about.
Commercial auto is also the strangest line in business insurance right now. Nearly everything else is getting cheaper. This is going the other way, hard, and for reasons that have nothing to do with your driving record. This page covers when the obligation attaches, what the federal floor actually is, and why the price keeps climbing. The wider picture is in our guide to small business insurance.
What's in this article
1. When a personal policy stops covering you
1.1 What triggers the exclusion
The National Association of Insurance Commissioners puts the warning to business owners plainly: if you rely on personal auto or liability insurance for vehicles used for business, look closely at the provisions, because business-related liability may be excluded.
The NAIC also describes what a commercial policy adds. Commercial auto policies typically carry higher liability limits — $1 million is the common example — and may include provisions covering rented and other non-owned vehicles, including employees' cars driven for company business.
The practical trigger is not a bright line, and that is the problem. It is a judgment about use. Driving to a single office every day is usually fine on a personal policy. Carrying tools, making deliveries, visiting client sites, transporting people for a fee, or registering the vehicle to the business generally is not. The NAIC's own guidance is direct on ownership: if your business owns or leases a vehicle, make sure the business name is listed on the policy as the principal insured.
The failure mode is quiet. You never learn the answer at purchase. You learn it at claim time, when an adjuster reads the application you filled in three years ago and asks what the vehicle was doing.
1.2 The three categories of vehicle
Almost every small business has vehicles in more than one of these buckets, and each needs a different answer.
| Category | What it means | What covers it |
|---|---|---|
| Owned | Titled or leased to the business | Commercial auto, vehicle scheduled on the policy |
| Hired | Rented, leased short-term, or borrowed for business use | Hired auto liability — often an endorsement, not automatic |
| Non-owned | Employees' personal vehicles used for business errands | Non-owned auto liability — almost never automatic |
The third row is where uninsured exposure concentrates in service businesses, professional firms and any company that reimburses mileage. If you pay mileage, you have non-owned auto exposure. Full stop.
2. Hired and non-owned auto: the endorsement nobody buys
Insurance Services Office publishes a Hired Auto and Non-owned Auto Liability endorsement for the standard business owner's policy. It is designed to provide excess liability coverage for bodily injury or property damage arising out of the use of a hired auto by the insured or its employees in the course of business, and out of the use of a non-owned auto in the insured's business.
Three things to understand about it:
- It is excess, not primary. It sits above whatever coverage the employee's own policy provides. If her personal limit is $50,000 and the claim is $800,000, her policy pays first and yours responds above it. If her policy denies the claim outright because of a business-use exclusion, the interaction gets complicated and you want a broker who can explain it before, not after.
- It does not cover the vehicle itself. Non-owned auto liability protects the business against third-party claims. It does not repair the employee's car.
- It is usually inexpensive relative to what it does. This is the closest thing to free money in small commercial insurance, and it is left on the table constantly.
Ask one question in writing: is the hired and non-owned auto endorsement attached to my policy, and at what limit? If the answer is no, ask what it would cost to add. The number will usually surprise you in the right direction.
3. The federal floor was set in 1985
Here is the fact that reframes this entire topic, and it is sitting in plain sight in the Code of Federal Regulations.
3.1 The schedule of limits
The Federal Motor Carrier Safety Administration prescribes minimum levels of financial responsibility in 49 CFR Part 387. The schedule for property carriers reads as follows — and note the column heading, which is reproduced here exactly as the regulation prints it.
| Type of carriage | Commodity | Minimum, as of January 1, 1985 |
|---|---|---|
| For-hire, interstate or foreign commerce, GVWR 10,001 lbs or more | Property (non-hazardous) | $750,000 |
| For-hire and private, GVWR 10,001 lbs or more | Hazardous substances in bulk, bulk explosives, certain gases and Class 7 materials | $5,000,000 |
| For-hire and private, GVWR 10,001 lbs or more | Oil, hazardous waste and other listed hazardous materials | $1,000,000 |
| For-hire and private, GVWR under 10,001 lbs | Certain explosives, Hazard Zone A materials, controlled quantities of Class 7 | $5,000,000 |
Separately, under § 387.303, a fleet consisting only of vehicles under 10,001 pounds GVWR carrying non-hazardous property must carry $300,000.
For passenger carriers, § 387.33 sets $5,000,000 for any vehicle with a seating capacity of 16 or more including the driver, and $1,500,000 for 15 or fewer.
Household goods movers carry a separate cargo requirement: $5,000 for loss or damage on any one vehicle, and $10,000 for losses at any one time and place.
And as of January 16, 2026, a property broker must hold a surety bond or trust fund of $75,000.
3.2 Who is inside the rules and who is outside
The federal rules do not reach most small businesses. Subpart A applies to for-hire carriers transporting property in interstate or foreign commerce, and to any carrier transporting hazardous materials. There is an explicit exception: the rules do not apply to a vehicle with a GVWR of less than 10,001 pounds, unless it is carrying certain hazardous materials.
Passenger carrier rules also carve out school transportation, taxis with fewer than seven seats not running a regular route, and vehicles carrying fewer than 16 people on a single daily round-trip commute.
So if you run three plumbing vans in one state, none of this applies to you directly. It still matters, for two reasons. It sets the floor that every truck on the road beside you is carrying, and it sets the expectation that shows up in contracts, because commercial clients frequently ask for auto limits benchmarked to it.
3.3 What has and hasn't changed
Note the shape of the regulation. Part 387 has been amended repeatedly, most recently in July 2026 and January 2026, on broker bonds, filing procedures and forms. The dollar figure for a for-hire truck carrying ordinary freight has stayed where it was put.
FMCSA has considered raising it. In 2014 the agency published an advance notice of proposed rulemaking on financial responsibility for motor carriers, seeking comment on whether to exercise its discretion under 49 U.S.C. 31138 and 31139 to increase the minimums above the statutory floor. The current schedule still shows the 1985 column.
Meanwhile — see section 5 — the insurance market has been repricing the actual cost of a serious truck accident upward for the better part of a decade. The regulation is a floor, not a limit, and treating it as adequate coverage is a category error.
4. Canada: compulsory everywhere, minimums that are almost decorative
The Insurance Bureau of Canada is unambiguous: purchasing auto insurance is mandatory across Canada, regardless of where your business is located. Beyond the mandatory coverage set by each province and territory, businesses can add commercial vehicle coverage for owned or leased cars, trucks or fleets.
IBC also flags something US-written articles never mention, and it matters more than the limits: vicarious liability. As a business owner, you are generally responsible for the negligence of employees and volunteers when they operate a vehicle or equipment on behalf of your organization. That is the Canadian version of the non-owned auto problem, and it applies to volunteers too, which is why nonprofits get caught by it.
The statutory minimums, per IBC's per-province guidance:
| Jurisdiction | Minimum third-party liability |
|---|---|
| Ontario, New Brunswick, Northwest Territories, Nunavut, Yukon and most other provinces | $200,000, plus accident benefits and uninsured automobile coverage |
| Nova Scotia | $500,000, plus direct compensation for property damage, accident benefits and uninsured coverage |
| Quebec | $50,000 civil liability from a private insurer, on top of the public plan administered by the SAAQ, which compensates bodily injury on a no-fault basis |
Read those numbers next to a serious injury claim and the conclusion writes itself. A $200,000 limit on a work vehicle is a legal formality, not a risk transfer. Most Canadian brokers will not offer a commercial policy at the statutory floor, and you should not ask for one.
Two further compliance layers apply to Canadian business vehicles: the federal Motor Vehicle Safety Act, which sets standards and inspection requirements, and Transport Canada's National Safety Code, which covers commercial vehicles, drivers and motor carriers. Provincial and local regulations sit on top.
5. Why this line keeps rising when everything else falls
The 2026 commercial insurance market is soft. Property is down sharply, cyber is down, directors and officers is down, workers' compensation is down. Commercial auto is not.
The Council of Insurance Agents & Brokers surveys brokers quarterly. In Q2 2026, with overall premiums down an average of 2.0% and commercial property down 6.3%, commercial auto premiums rose 4.5% and umbrella rose 5.3% — the largest increase of any line, and umbrella's 35th consecutive quarter of increases.
In Q1 2026, commercial auto rose 5.8%, the third straight quarter in which it was the fastest-rising line, and CIAB noted the line has posted increases every quarter for nearly five years.
The reasons brokers give are not about frequency alone. CIAB's report cites AM Best data showing commercial auto has produced annual loss ratios above 100% every year since 2014, with the single exception of 2021, and net underwriting losses exceeding $5 billion in both 2023 and 2024 — loss ratios of 109.2 and 107.2. AM Best has described commercial auto as one of the worst-performing property and casualty segments of the last decade.
The drivers CIAB identifies: distracted driving and congested roads keeping claim frequency high; rising medical costs after an accident; vehicle repair and replacement costs inflated by the technology in modern vehicles; and social inflation and large jury verdicts amplifying severity.
What this means for your renewal. Do not benchmark your commercial auto renewal against the market headline. If your broker tells you the market is softening and your auto renewal came back up 5%, both statements are true. The place to negotiate is everywhere else. If your budget is fixed, this is the year to move money out of lines that are getting cheaper and into limits on the line that is not — which usually means an umbrella. See commercial umbrella and excess liability for how the layers interact.
6. What commercial auto costs in 2026
No regulator publishes an average commercial auto premium. Every figure below comes from a publisher that sells or compares insurance, describing its own customers. Collected September 5, 2026.
| Benchmark | Figure | Published by |
|---|---|---|
| Small business average | $147/month ($1,762/year) | Insureon, from policies its customers bought |
| Average per month | $270 | Progressive Commercial |
| Small business average | $574/month | The Hartford |
| Distribution | 20% pay $100 or less; 23% pay $100–$200; 37% pay over $200 | Next Insurance |
| By vehicle type | Contractors $172; tow trucks $396; for-hire specialty trucks $649; for-hire transport trucks $1,068 | Progressive Commercial |
Four publishers, and the spread between the low and high average is roughly four times. None of them is wrong. They are describing different vehicles.
That last row is the actual answer to "what does commercial auto cost." A contractor's pickup and a for-hire transport truck are not the same product with different price tags; they are different risks by an order of magnitude. What drives your number, roughly in order: vehicle weight class and type, radius of operation, what you haul or carry, driver motor vehicle records, your limits, and your loss history.
One structural note. Commercial auto is rated per vehicle. Adding a van to a three-van fleet raises your premium by roughly a quarter. Adding an employee who drives her own car raises it by almost nothing — which is precisely why the non-owned exposure in section 2 is so easy to under-buy.
7. Eight questions before your renewal
- Which vehicles are scheduled, and is anything missing? Cross-check the policy against your actual fleet, including anything bought mid-term.
- Is the hired and non-owned auto endorsement attached, and at what limit?
- Is the business named as the principal insured on every vehicle it owns or leases?
- What are my liability limits, and how do they compare with what my contracts require?
- Do I have physical damage coverage — comprehensive and collision — on vehicles I still owe money on?
- Are permanently attached items covered? The NAIC specifically flags generators, storage units and similar equipment as things to insure deliberately.
- What is my radius of operation on file, and is it accurate? Radius creep is a common cause of coverage disputes.
- Have I run motor vehicle records on every driver this year? Driver records move commercial auto pricing more than almost anything else you control.
If you employ people who drive, this line connects directly to two others: workers' compensation covers the driver's own injuries, and commercial auto covers everyone else's. Neither covers the other.
8. Frequently asked questions
Do I need commercial auto insurance for my business?
If a vehicle is owned or leased by the business, almost certainly yes, and the NAIC advises making sure the business is named as the principal insured. If you or your employees use personal vehicles for business, the NAIC warns that business-related liability may be excluded from personal policies, which is what hired and non-owned auto coverage is for. In Canada, auto insurance is mandatory in every province and territory, and the Insurance Bureau of Canada notes that business owners are generally vicariously liable for employees and volunteers driving on the organization's behalf.
What is the difference between commercial and personal auto insurance?
Commercial policies typically carry higher liability limits — $1 million is a common example per the NAIC — and may include provisions covering rented and non-owned vehicles, including employees' cars driven for company business. Personal policies generally exclude or limit business use. The distinction is about how the vehicle is used and who owns it, not about what kind of vehicle it is.
What are the federal minimum insurance requirements for trucks?
Under 49 CFR 387.9, for-hire carriers of non-hazardous property in interstate commerce with a GVWR of 10,001 pounds or more must carry $750,000. Carriers of oil and listed hazardous materials must carry $1,000,000, and carriers of hazardous substances in bulk must carry $5,000,000. Fleets made up only of vehicles under 10,001 pounds carrying non-hazardous property must carry $300,000. Passenger carriers must carry $5,000,000 for vehicles seating 16 or more and $1,500,000 for 15 or fewer. The schedule of limits in the regulation is still headed "January 1, 1985."
Does commercial auto insurance cover employees using their own cars?
Not automatically. That is non-owned auto liability, which is generally added by endorsement. ISO publishes a hired and non-owned auto endorsement for the business owner's policy that provides excess liability coverage for both hired vehicles and employees' own vehicles used in the business. It protects the business against third-party claims; it does not repair the employee's vehicle.
How much does commercial auto insurance cost per month?
Publishers reporting on their own customers give figures from about $147 a month (Insureon) to $270 (Progressive Commercial) to $574 (The Hartford). The spread reflects vehicle mix rather than disagreement. Progressive's own breakdown makes the point: contractors average $172 a month while for-hire transport trucks average $1,068. Your weight class, radius, cargo, driver records and limits move the price far more than the carrier does.
Why is my commercial auto premium going up when other insurance is getting cheaper?
Because commercial auto is the exception to a soft market. CIAB's Q2 2026 broker survey found overall commercial premiums down 2.0% and commercial property down 6.3%, while commercial auto rose 4.5%. CIAB cites AM Best data showing the line has run loss ratios above 100% every year since 2014 except 2021, with net underwriting losses over $5 billion in both 2023 and 2024. Distracted driving, medical cost inflation, expensive vehicle repairs and large jury verdicts are the drivers brokers name.
What is the minimum auto insurance for a business in Canada?
Auto insurance is compulsory in every province and territory. Per the Insurance Bureau of Canada, most jurisdictions set third-party liability at $200,000 plus accident benefits and uninsured automobile coverage; Nova Scotia requires $500,000; Quebec requires $50,000 in civil liability from a private insurer, alongside the public SAAQ plan that compensates bodily injury. These are statutory floors, not adequate commercial limits, and most business policies are written far above them.
Does a business owner's policy include commercial auto?
No. The NAIC states that a business owner's policy typically does not include commercial auto insurance. A BOP can carry the hired and non-owned auto endorsement, which is excess coverage for vehicles you do not own — it is not a substitute for scheduling the vehicles the business owns.
