What is commercial auto insurance in Texas?

This guide explains what commercial auto insurance is in Texas, what the consumer Auto insurance guide from the Texas Department of Insurance (TDI) lists among the things most policies don't cover, and how to check where your own driving sits.

The short version. Commercial auto insurance in Texas, per TDI's Commercial property insurance guide, "includes liability and property damage protection for cars, trucks and vans that you use for business." TDI's consumer Auto insurance guide lists accidents while driving for business among the things most policies don't cover, which this article reads as ordinary auto policies, and adds that coverages vary by policy, so read your policy or talk to your agent.

Here's what we'll cover: how TDI defines commercial auto insurance, what TDI says most auto policies don't cover, the company-owned car line in TDI's guide, how business use can affect your rates, liability limits and umbrella coverage, why this guide gives no price, and steps you can take to check your own position.

What TDI says commercial auto insurance is

Commercial auto insurance in Texas is described by TDI as coverage for vehicles used for business. TDI's Commercial property insurance guide (last updated 12/9/2025) is mainly about insuring buildings and business property, and it defines commercial auto under the coverages a business might also need: "Commercial auto insurance includes liability and property damage protection for cars, trucks and vans that you use for business."

The same paragraph of that guide goes on to other vehicle types: "It can also cover food trucks, service utility trucks, trailers, and other types of vehicles." TDI words this as something the coverage can do, so the guide describes what the coverage type may reach and does not say what any one policy includes.

Two things follow from TDI's wording. The definition turns on how a vehicle is used, so the same pickup could be a personal vehicle on Saturday and a business vehicle on Tuesday. Trailers, food trucks and service utility trucks are named, so they are fair questions to raise by name when you talk to the agent or company that insures the business.

What TDI says most auto policies don't cover

TDI's consumer Auto insurance guide (last updated 12/11/2025) includes a table of things most policies do and don't cover, and driving for business is on the side most policies don't cover. TDI introduces the table by saying that coverages vary by policy and depend on the types of coverages you choose, that the table shows some of the things most policies do and don't cover, and that you should read your policy or talk to your agent to be sure of your exact coverages.

That guide is written for consumers, so this article reads its phrase most policies as the ordinary auto policies the guide describes. Three entries on the side of the table that most policies don't cover touch business driving, each subject to the caveat above:

• Driving for business. The entry reads: "Accidents that happen while you’re driving in Mexico, driving for business, or racing".
• Ride-hailing and paid delivery. The column also lists accidents that happen while you're driving for a ride-hailing service or delivering food or other items for a fee.
• A car you don't own but could use regularly. The column lists accidents in such a car and gives a company-owned car as its example, covered in the next section.

The ride-hailing and delivery entry is a case of its own, and our guide on rideshare insurance in Texas covers it in detail.

For a plumber's truck, a caterer's van or a contractor's trailer, the practical point is that an ordinary auto policy may not respond to an accident while the vehicle is being driven for business. TDI's guide does not define driving for business, so check how your own policy words it.

The company-owned car line in TDI's guide

One entry in TDI's table may matter to employees as well as business owners, because it is about a vehicle that belongs to someone else. In its Auto insurance guide, among the things most policies don't cover and under the caveat that coverages vary by policy, TDI lists: "Accidents that happen while you’re driving a car that doesn’t belong to you but you could use regularly, like a company-owned car".

The entry is worded around two things, a car that doesn't belong to you and regular access to it. A shop truck, a pool car or a van several people share could all fit that description, though only your policy's wording can tell you how it treats one.

The opposite direction is handled in a different passage of the guide. It says most policies cover you, your family, and people driving your car with your permission, and it tells readers to ask their agent or read their policy to know who is covered and whether anyone is excluded.

For a business, the vehicles your staff drive and the personal cars your staff use on business errands are worth raising one by one with the agent or company that insures the business. Which of them a policy covers, and on what terms, is a question for the policy wording.

Rental cars get similar treatment in the same TDI guide. It says you might not need the rental agency's liability policy if you're driving a rental car for personal use, that your own auto policy might provide coverage, and that there could be exclusions that limit or reduce it. Then it adds: "Ask your insurance agent if your policy covers you if you’re driving the rental car for work."

What TDI says about business use and your auto rates

How you use a car is one of the things TDI says most companies consider when setting an auto premium. In its section on understanding premiums, TDI's Auto insurance guide lists the things most companies consider when deciding your auto insurance premium, and one item reads: "How you use your car. Your rates will be higher if you drive your car to and from work or use it for business."

TDI's guide gives no figure for the difference, and this guide doesn't estimate one. What the line does show is that use is information a company may ask about, so it makes sense to describe your driving accurately when you buy or renew.

Price comparisons need the same care. In the shopping tips of its Commercial property insurance guide, which are written about commercial property policies, TDI says to compare policies with similar coverage when comparing prices and notes that a cheaper policy might provide less coverage.

What TDI says about liability limits and umbrella coverage

TDI's consumer auto guide gives a minimum liability figure for Texas drivers and suggests thinking about more. The Auto insurance guide (last updated 12/11/2025) says: "Texas law requires you to have at least $30,000 of coverage for injuries per person, up to a total of $60,000 per accident, and $25,000 of coverage for property damage. This is called 30/60/25 coverage."

In the same passage, TDI suggests thinking about buying more liability coverage. It says the minimum liability limits might be too low if you cause a multi-vehicle accident or the other driver's car is totaled, and that if you don't have enough liability coverage you might have to pay the rest out of your own pocket.

Those statements come from TDI's guide for consumers. The TDI pages cited here do not set out separate limits for business vehicles, and this guide doesn't either. Since TDI says the minimum might be too low, look at your limit on purpose. A contract, lease or lender may also ask for a particular limit, and that is a matter of the document you signed.

Umbrella coverage is described on a different TDI page. TDI's Commercial general liability insurance page (last updated 1/20/2021) says: "Umbrella liability insurance is excess liability insurance coverage above the limits of automobile liability and CGL policies." Our guide on umbrella insurance in Texas covers how that works, and what a small business needs to insure in Texas covers the liability side that sits alongside the vehicles.

What does commercial auto insurance cost in Texas?

This guide gives no price for commercial auto insurance in Texas, and it won't guess one. Neither TDI's Auto insurance guide nor its Commercial property insurance guide publishes a price for it, and a number without a source would be no use to you.

The Commercial property insurance guide does offer general points on the cost of business coverage. They are written about commercial property policies, so treat them as background for a commercial auto conversation:

• Deductibles. Policies with higher deductibles have lower premiums, according to the guide, and choosing a higher deductible means paying more out of pocket if you have a claim.
• Shopping. Coverage and rates vary by company, the guide says.
• Licensing. The guide says to buy only from licensed companies, because if you buy from an unlicensed company your claims might not get paid. It says you can learn whether a company or agent is licensed by calling TDI's Help Line, 800-252-3439, or using TDI's company lookup.

What to do with this

These are steps you can take to work out where your own vehicles stand. The facts inside each step come from the TDI pages linked above, and the checklist itself is ours.

• Start with how each vehicle is used. TDI's definition of commercial auto in its Commercial property insurance guide is about cars, trucks and vans that you use for business.
• Read the table in TDI's Auto insurance guide. Driving for business, paid delivery and the company-owned car entry all sit on the side of the table that most policies don't cover, under TDI's note that coverages vary by policy.
• Raise shared and company vehicles specifically. Ask how the policy treats a car that doesn't belong to the driver but is available for regular use.
• Describe your use accurately at quote and renewal. TDI's Auto insurance guide lists how you use your car among the things most companies consider when deciding a premium.
• Ask about trailers and specialty vehicles by name. TDI's definition says commercial auto can also cover them, and what a given policy covers is set by that policy.
• Check any limit a contract or lease asks for before choosing one, and consider whether an umbrella policy belongs above it.
• Ask your agent about rentals used for work. TDI's Auto insurance guide suggests that question in its section on rental cars.
• Compare policies with similar coverage, and check licensing. Both points are in the shopping tips of TDI's Commercial property insurance guide.
