Whether you’re delivering food, hauling equipment, or transporting clients, using a vehicle for business purposes comes with added risk, and personal auto insurance won’t cover it. That’s where commercial auto insurance comes in. If you’re a business owner in Minnesota or South Dakota, you may be legally required to carry commercial insurance coverage. But even if you’re not, failing to protect your business vehicles could expose you to costly lawsuits and uncovered losses.

At First State Insurance, we help local businesses—from solo contractors in Worthington to growing delivery fleets in Sioux Falls—secure the right protection for their vehicles. In this guide, we’ll explain what commercial auto insurance is, what it covers, and why it’s essential for your business.

Key Takeaways

  • Personal auto insurance does not cover for vehicle use for business purposes. Commercial auto insurance is specialized to cover such liabilities that occur during business use.
  • Commercial auto insurance covers various risks and liabilities like liability coverage, physical damages, medical coverage, etc.
  • Besides coverage benefits, getting commercial auto insurance also has tax benefits for your business.

What Is Commercial Auto Insurance?   

Commercial auto insurance is a type of business insurance that provides liability and physical damage coverage for vehicles used for business purposes. It applies to cars, vans, trucks, and specialty vehicles that are owned, leased, or rented by a business, or personally owned vehicles used for work.

According to the Insurance Information Institute (III), personal car insurance typically excludes coverage for any work-related driving, which means you could be left paying out-of-pocket if an accident occurs while you’re on the job.

Who Needs Commercial Auto Insurance?   

You may need a commercial auto policy if:

  • You own or lease vehicles under your business name
  • You or your employees drive for work purposes
  • You transport tools, products, or equipment
  • You deliver goods or people for a fee
  • You operate in industries like construction, delivery, real estate, or trucking

Even sole proprietors and freelancers can benefit. For example, if you’re a contractor using a pickup truck with business signage and tool storage, that qualifies as business use, and your personal policy may not apply.

What Does Commercial Auto Insurance Cover?   

Several costs and liabilities are covered by commercial auto insurance. Generally, commercial auto policies can be customized, but most include the following core coverages:

1. Liability Coverage   

Covers bodily injury and property damage if you’re at fault in an accident. In most states, this is required by law due to its importance in covering everyday accidents. For example, if your employee rear-ends another vehicle while making deliveries, liability coverage helps pay for medical bills and vehicle repairs.

2. Physical Damage (Collision & Comprehensive)   

On one hand, collision coverage covers damage to your vehicle from an accident, regardless of fault. On the other hand, comprehensive coverage covers non-collision events like theft, vandalism, weather damage, or hitting an animal.

3. Medical Payments (MedPay) or Personal Injury Protection (PIP)   

This type of coverage is for medical expenses for the driver and passengers in your business vehicle, no matter who’s at fault. Regarding this topic, Minnesota is a no-fault state, which means PIP coverage is required, according to the Minnesota Department of Commerce.

4. Uninsured/Underinsured Motorist Coverage   

It protects your business if you’re hit by someone who doesn’t have insurance or doesn’t have enough coverage to pay for your losses.

5. Hired and Non-Owned Auto Coverage (HNOA)   

This covers vehicles that your business doesn’t own, such as rental cars or employees’ personal vehicles used for work tasks. Especially useful for businesses with mobile sales reps or food delivery services.

 Optional Add-Ons Worth Considering   

  • Depending on your business and risk tolerance, you may also want to add:
  • Towing and Roadside Assistance
  • Rental Reimbursement
  • Gap Coverage (for leased or financed vehicles)
  • Trailer Interchange Coverage
  • Cargo Insurance (especially for trucking or delivery businesses)

At First State Insurance, we’ll help you customize a policy that matches your fleet’s actual risks—not just the state minimums.

How Much Does Commercial Auto Insurance Cost?   

The cost of commercial auto insurance varies widely based on:

  • Type and number of vehicles
  • Industry risk level
  • Driver records
  • Coverage limits
  • Location and driving radius
  • Claims history


According to Progressive Commercial, small business owners can expect to pay between $1,200 and $2,400 per year per vehicle for a standard policy.

Trucking companies or those with heavy-duty vehicles may pay significantly more, especially if they cross state lines or transport hazardous materials.

Are Commercial Auto Insurance Premiums Tax-Deductible? 

Yes, commercial auto insurance premiums are tax-deductible for businesses. The Internal Revenue Service (IRS) typically considers the cost of business insurance, including commercial auto premiums, to be an ordinary and necessary business expense, which can be deducted from your taxable income.

You still need to be aware of the limitations set by the IRS. For instance, you cannot deduct the premium from your taxes if you choose to use the Standard Mileage Rate Method. Also, if the same insured vehicle is used for both business and personal use, you can only deduct the portion of the premium that corresponds to its business use of the insured vehicle.

What Happens if You Don’t Have Commercial Insurance Coverage?   

Driving a business vehicle without the proper insurance can have serious consequences:

  • Claim denials: Your personal auto policy may reject claims for business use.
  • Legal fines: Most states—including Minnesota and South Dakota—require liability coverage for commercial vehicles.
  • Lawsuits: Without liability insurance protection, your business could be on the hook for hundreds of thousands in damages.
  • License suspension: Repeated violations could result in your business losing its operating license or DOT registration.


Don’t assume your personal policy will protect you. It almost certainly won’t if you’re hauling inventory or heading to a job site.
