Commercial auto insurance: what Bay Area business owners get wrong about fleet coverage

I've insured Bay Area businesses for over 50 years — plumbers, electricians, caterers, landscapers, property managers, you name it. And in all that time, the single most common coverage gap I see is commercial auto.

It's not that business owners don't care. It's that they don't know. They assume their personal auto policy covers them when they're driving to a job site. They assume their employee's personal policy covers the employee driving a company truck. They assume their general liability handles anything involving a vehicle.

All three assumptions are wrong. And I've seen each one cost a business owner six figures.

The gap nobody talks about

Here's how it usually goes. A business owner has three or four vehicles — work trucks, a van, maybe a trailer. The owner's personal auto policy covers the owner's personal car. The business has a general liability policy and maybe a BOP. Everything feels covered.

Then an employee backs a company truck into a parked car in a client's driveway. Or rear-ends someone on 101 during the afternoon commute. Or a delivery driver runs a stop sign in Redwood City.

The business owner calls their personal auto carrier. The carrier says: "That vehicle is titled to the business. It's not on your personal policy. We can't help you."

The business owner calls their GL carrier. The carrier says: "General liability excludes auto. You need a commercial auto policy."

Now you have a claim with no coverage. And if there are injuries involved, you're looking at a lawsuit with no insurer behind you. I've seen this exact scenario play out more times than I can count.

Personal auto does not cover business use

This is the number one thing I want every Bay Area business owner to understand: your personal auto insurance policy has a business use exclusion.

If a vehicle is titled to a business, registered to a business, or regularly used for business purposes, personal auto typically won't respond to a claim. It doesn't matter that you're the owner of both the car and the company. The carrier will look at how the vehicle was being used at the time of the loss.

And it goes the other way too. If your employee is driving their own car to pick up supplies for your job site and causes an accident, your business can be named in that lawsuit. The injured party's attorney isn't going to sue just the employee making $25 an hour. They're going to sue the business with assets.

That's where Hired and Non-Owned Auto (HNOA) coverage comes in — and most small business owners have never heard of it.

The five mistakes I see over and over

After 50 years of writing commercial auto policies on the Peninsula and in San Francisco, the mistakes are remarkably consistent.

Mistake #1: No commercial auto policy at all

This is the most dangerous one and it's more common than you'd think. A contractor with two work trucks and no commercial auto policy. A caterer with a delivery van on a personal policy. A property manager using their personal car to visit rental units every day.

If you own a business and any vehicle is used for business purposes — even occasionally — you need to at least have the conversation about commercial auto.

Mistake #2: Wrong liability limits

California's minimum auto liability limits are 15/30/5 — $15,000 per person, $30,000 per accident for bodily injury, and $5,000 for property damage. Those minimums are a joke. A single trip to the emergency room can exceed $15,000. A rear-end collision on El Camino Real can total a $60,000 SUV.

For a business, I almost always recommend $1,000,000 combined single limit (CSL) at minimum. If you have a commercial umbrella, your underlying auto limits need to meet the umbrella carrier's requirements — typically $500,000 or $1,000,000 CSL.

Mistake #3: Not listing every driver

Commercial auto policies require you to list drivers. If an unlisted employee gets into an accident in a company vehicle, you could have a coverage issue. Every time you hire someone who might drive a company vehicle — even occasionally — they need to be added to the policy. Their MVR (motor vehicle report) needs to be pulled. This is especially important for businesses with high turnover.

Mistake #4: Ignoring Hired and Non-Owned Auto

If your employees ever use their personal vehicles for business purposes — driving to a client site, picking up materials, making deliveries — you need HNOA coverage. This is typically added as an endorsement to your commercial auto or general liability policy, and it's not expensive. But without it, you have a gap that could be catastrophic.

I insured a landscaping company on the Peninsula years ago. One of their crew members was driving his own truck to a job in Atherton and T-boned another car at an intersection. The injured driver's attorney sued both the employee and the company. The company's GL policy excluded auto. The employee's personal auto had minimum limits. Without HNOA, the business would have been exposed for the entire judgment above the employee's $15,000 limit.

They had HNOA. It responded. That endorsement cost them a few hundred dollars a year.

Mistake #5: Not matching the vehicle to the right classification

Commercial auto premiums are based on vehicle type, use, and radius. A pickup truck used for local service calls is rated differently than a box truck making regional deliveries. If your vehicles are misclassified — or if you've added vehicles and haven't updated the policy — your premium might be wrong and your coverage might not respond the way you expect.

Every time you add a vehicle, change how a vehicle is used, or expand your service area, call your agent. It takes five minutes and it prevents audit surprises.

What commercial auto actually covers

A standard commercial auto policy includes:

For businesses with multiple vehicles, you're looking at a fleet policy, which typically means five or more vehicles. Fleet policies can offer volume discounts and simplified management — one policy, one renewal, one bill.

The Bay Area factor

Commercial auto is expensive everywhere right now, and the Bay Area is no exception. Rates have been climbing for years, driven by:

None of that is going to change anytime soon. Which means the temptation to reduce limits or drop coverage is real. I understand the impulse — but it's exactly the wrong response. When claim costs go up, you need more coverage, not less.

When to call your agent

Here's a simple rule: if something changes with your vehicles or your drivers, call your agent. Specifically:

Any of those should trigger a five-minute phone call. That's it. Five minutes now versus five figures later.

The bottom line

Commercial auto isn't complicated. But it does require attention. The businesses that get it right are the ones that treat their vehicles like what they are — rolling liabilities that need proper coverage.

If you're a Bay Area business owner with one vehicle or fifty, and you're not sure whether your current setup is right, send me your declarations page. I'll look at it and tell you — honestly — whether you're covered or whether you have a gap. No cost, no obligation.

After 50 years, I've seen what happens when businesses get this wrong. I'd rather spend five minutes reviewing your policy than watch you spend five years paying off a judgment.
