A company car is a tool. You buy it, insure it, and expect it to move your business forward. But what happens when that tool leaves the job site and goes to the grocery store? What happens when your employee uses their own car to make a delivery?
The answer is simple.
Your risk goes up. And your personal auto policy likely walks away.
Here is what you need to know about the line between business and personal use, and why it matters for your coverage.
What Counts as Business Use of a Vehicle?
You might think “business use” only means hauling cargo in a branded van. In the eyes of insurers, the definition is broader.
Business use includes any driving done to benefit your company. The National Association of Insurance Commissioners (NAIC) and major carriers look at the primary function of the trip, not the logo on the door.
Here are common activities:
- Delivering goods or supplies to customers or job sites
- Transporting clients to meetings, lunches, or events
- Hauling tools, equipment, or materials for a job
- Traveling between work locations like offices, warehouses, or client sites
- Running business errands, such as bank deposits or picking up parts
Even a quick trip to the post office counts if you are mailing business documents.
The challenge is the gray area. Many business owners blur the line between commuting and working. You drive from home to the office. That is personal. You drive from the office to a client meeting.
That is business.
Employees Using Personal Vehicles for Work-Related Activities
Many businesses rely on employees who drive their own cars. This setup is common for real estate agents, sales reps, contractors, and delivery drivers.
Here is the problem. Almost all personal vehicle insurance policies exclude commercial use. If your employee gets into an accident while running a work errand, their insurer might deny the claim. You read that right.
Deny the claim.
Why?
Because the car was being utilized for business use. The pricing of the policy was set for private driving, not for business use.
Your business then faces vicarious liability. This legal notion makes you liable for the acts of your employees during their employment. A court might rule that you owe damages if the accident happened during work hours.
The data backs this up. Commercial auto claims volume remained 14% higher in 2025 than in 2021, reflecting an expansion of driving risk. Gig-related claims jumped 96% since 2021 and now account for 10% of all commercial auto claims.
You cannot assume your employee’s insurance will cover the loss. It often will not.
Personal Use of Company-Owned Vehicles
Now flip the situation. You own the vehicle. An employee takes it home.
The Internal Revenue Service treats personal use of a company vehicle as a taxable fringe benefit. If your employee drives the company truck to the beach on Saturday, the IRS considers that income. You must report it on their W-2.
This creates two headaches.
- First, you need a clear policy on personal use. The IRS offers valuation methods like the Annual Lease Value or Cents-Per-Mile method to calculate the taxable amount. Without records, the IRS may tax the entire value of the vehicle.
- Second, your commercial vehicle coverage must match the reality of how the vehicle is used. If your policy lists the vehicle as “business only” and an employee gets into an accident during a personal trip, the insurer might deny the claim. If your policy lists it as “business and personal,” you pay a higher premium.
The IRS allows a de minimis rule for small personal stops, like grabbing lunch between two business deliveries. But regular commuting is personal use. You must track it.
Employees Taking Company Vehicles Home
Letting an employee take a company vehicle home is convenient. It saves time in the morning. It keeps tools secure. But it creates exposure.
A vehicle parked in an employee’s driveway is still your liability. If a family member takes it for a joyride and causes an accident, your business auto insurance faces the claim.
You should have a written policy. It should state:
- Who is allowed to drive the vehicle?
- Are family members prohibited?
- How to report accidents?
- The consequences of unauthorized use?
Without this policy, you leave your coverage to chance.
Transporting Clients, Equipment, Tools, or Materials
Every cargo type carries a different risk.
- When you transport clients, you add bodily injury exposure. A fender bender with a client in the car becomes a lawsuit. Their medical bills and lost wages land on your desk.
- When you haul equipment, you risk property damage. A dropped generator or a spilled load costs money. If the equipment belongs to a client, the claim is worse.
The 2025 claims data shows commercial auto claims remain elevated. The insurance industry has struggled with commercial auto liability profitability since 2010. The projected combined ratio for 2025 sits at 110.6%, meaning insurers pay out more than they collect in premiums.
This is why insurers scrutinize your operations. They want to know what you carry, where you drive, and who is behind the wheel.
Why Personal Auto Insurance May Not Cover Business-Related Use
This point deserves emphasis. Personal auto policies exclude business use.
The exclusions are explicit. Carrying persons or property for a fee. Using a vehicle in the course of any business. Delivering goods for wholesale or retail.
If you are driving for work and get into an accident, your personal insurance company could reject coverage. Additionally, they could revoke your insurance.
Consider this scenario. You own a landscaping business. You use your personal pickup truck to haul mulch and mowers. You get into an accident. Your personal insurer sees the lawnmowers in the bed and the business name on your shirt. They deny the claim. You pay out of pocket for the other driver’s injuries. You pay for your own truck repairs. You face a lawsuit without insurance.
That is the risk of business use of personal vehicles. It is a silent gap in coverage that most people do not notice until it is too late.
When a Business Should Review Its Commercial Auto Coverage
You should review your commercial auto insurance in several situations:
- You hire your first employee who drives for work
- You add a new vehicle to the fleet
- Your employees begin using personal cars for business tasks
- You start offering delivery or client transport
- Your business expands to new states or regions
- You change the type of cargo you haul
Do not wait for an accident. Review your policy now.
Ask your agent these questions:
- Does my policy cover employees using personal vehicles?
- Do I have hired and non-owned auto liability coverage?
- Are all drivers listed correctly?
- Does my policy match my actual driving patterns?
The insurance industry projects continued challenges in commercial auto liability. Carriers emphasize risk selection and higher rates to address these trends. You need a policy that reflects your true exposure.
The Gonzalez Insurance Approach
Commercial auto insurance is critical for any business with company vehicles, even a single company vehicle. Insurance companies often fail to get the proper amount of coverage for the type of vehicle being used and the risk factors inherent in the type of business.
This means when an accident occurs, your policy falls far short of the coverage you need. At Gonzalez & Company, we work hard to make sure that does not happen.
We study your company’s driving patterns. We ask detailed questions about how your business uses its vehicles.
- Are they used for heavy travel or heavy lifting?
- Do you cover a lot of territory behind those wheels, or is driving strictly local?
- Are there other risk factors?
Once we have all the information, we create a program that covers the potential situations that apply uniquely to you and your business. We will not give you a one-size-fits-all policy. We custom-tailor a policy that offers appropriate coverage for liability, bodily injury, property damage, replacement value, and many other factors.
The result? When disaster strikes, your policy will have anticipated what coverage you really need.
