Using Your Personal Vehicle for Business? Here’s What You’re Exposing

Key takeaways

A lot of small business owners, solopreneurs, and contract workers use their own vehicle for business. Running errands. Driving to sales meetings. Realtors across DFW taking clients out to view homes.

Most of them are writing the mileage off on their taxes. Far fewer have looked at what that does to their liability.

It feels like a non-issue, and for most people it stays one right up until it doesn’t.

Where your vehicle actually sits

The exposure most people don't see

When you use a vehicle for business, you’re assuming responsibility for the people in it and their injuries, whether they’re employees or clients.

And if you’re driving a vehicle titled in your personal name, meaning you purchased it as an individual and it’s tied to your person and not to the company or the LLC, then you’ve opened up the opportunity for an attorney representing a plaintiff for bodily injury to reach your personal assets as well as your business assets.

Both are going to be named in the claim or lawsuit.

That’s the piece people miss. The write-off is a tax decision. The titling is a liability decision. They are not the same decision, and making the first one without addressing the second is exactly where the exposure lives.

How to wall off that liability

There are ways to close this.

If you’re a business owner or entrepreneur using your own vehicle for business, especially if you’re writing it off on your taxes, you should have some type of commercial auto policy.

And there’s a second piece that gets skipped constantly. If you have a vehicle in your personal name and you have a commercial auto policy, you need what’s called a leaseback agreement. That’s a document where you, as the individual, sign over or lease that vehicle to the business.

The purpose of that agreement is to create a wall of liability, so that you as a person aren’t implicated in a potential claim or lawsuit alongside the business.

Whether that structure fits your situation depends on your entity, your titling, and how the vehicle is actually being used. That’s a conversation worth having with your agent and your accountant together, rather than assuming the policy alone has you covered.

The write-off is a tax decision. The titling is a liability decision. They are not the same decision.

The underwriting question that surprises everyone

When I’m writing a commercial auto policy for a carrier, one of the underwriting questions is whether the drivers are covered for workers compensation insurance elsewhere.

People always ask what comp has to do with their trucks.

Here’s why it matters. If there’s bodily injury to that employee, or to the owner, while they’re driving that vehicle, the auto carrier is now on the hook for all of it. The hospitalization, the emergency room trip, the injury costs. That’s in addition to the physical damage to the vehicles, and in addition to any bodily injury or property damage to other people and other people’s property.

Carriers naturally don’t want to be paying those costs when a workers comp policy would pay for them instead. So it greatly impacts the rate.

If I have two clients who both carry commercial auto, and one carries workers comp and one doesn’t, I can almost guarantee you the one without comp is going to be at a higher rate on that auto policy.

This lands harder in Texas than in most states, because Texas doesn’t require most private employers to carry workers compensation. A lot of small operations here skip it to save the premium, then find that the savings partially reappear as a higher commercial auto rate, and that injury costs have nowhere else to go.

Before you hand anyone the keys

One more, and it’s cheap to do.

If you’re hiring employees who are going to be driving company vehicles, you need to run a motor vehicle report on them first.

You want to confirm they have a clean driving record, and you want to see what their claims history looks like.

If you don’t, that’s going to significantly impact the premium for your commercial auto, and you’ll end up learning about a driver’s history at the worst possible time, which is after the rate comes back or after a loss.

The short version

If any of these describe you, it’s worth a conversation:
Each of those is either an open question on the liability side, a line item working against your premium, or both.

Frequently asked questions

If the vehicle is used for business, most likely yes. Personal auto policies commonly limit or exclude business use, which means a claim that happens while you’re working may not be covered at all. If you’re writing vehicle expenses off on your taxes, that’s a strong signal the vehicle needs some form of commercial auto coverage.
It’s a document in which you, as an individual, lease or sign over your personally titled vehicle to your business. It’s used alongside a commercial auto policy to separate you personally from the business, so that a bodily injury claim doesn’t automatically reach your personal assets as well as your business assets.
Yes. Carriers ask whether your drivers are covered for workers comp elsewhere, because without it the auto policy absorbs employee injury costs on top of vehicle damage and third-party claims. Between two otherwise similar businesses, the one without workers comp will generally see a higher commercial auto rate.
Often not. Driving clients or prospects is business use, and personal auto policies commonly exclude it. This catches realtors in particular, since taking clients to view properties is a routine part of the job that most people never think of as a coverage question. It’s worth reading your policy language or having your agent read it with you.
