Hired and Non-Owned Auto Insurance (HNOA), Explained for California Businesses
Hired and non-owned auto insurance (HNOA) is liability coverage for your business when someone drives a vehicle your business doesn't own on company business. That covers an employee running to the bank in their own car, a manager driving a rental to a trade show, or an office assistant picking up supplies. If that driver causes a crash, the injured person can sue your company as well as the driver. HNOA is what pays your company's defense and any judgment against it.
Most California small businesses don't own a single vehicle, so they assume auto insurance isn't their problem. That's the gap. A standard general liability policy excludes auto accidents, and the employee's personal auto policy protects the employee, not your company, and only up to their limits. HNOA is usually inexpensive to add to your business insurance, and it closes one of the most common holes we see in small-business programs.
What "hired" and "non-owned" mean
The two halves of HNOA cover two different situations. The definitions below come from the standard ISO forms. Your carrier's wording may differ, so check your own policy.
Term | What it typically means | Common examples |
Hired auto | A vehicle your business leases, hires, rents or borrows. This usually excludes vehicles borrowed or rented from your own employees, partners, officers or their households. | A rental car for a sales trip, a box truck rented for a one-day move, a car borrowed from a vendor |
Non-owned auto | A vehicle your business doesn't own, lease, hire, rent or borrow that is used in connection with your business. This expressly includes employees' and owners' personal cars while used in your business. | An employee driving to a client meeting, a bookkeeper making a bank deposit, an owner picking up parts in a personal truck |
HNOA is liability-only in most forms. It responds when your business is legally responsible for injuring someone or damaging their property. It is not physical damage coverage for the car being driven.
Why your business gets sued for an employee's crash
Respondeat superior: the employer answers for the employee
California law makes a principal responsible for an agent's negligence in the business of the agency. Civil Code §2338 says a principal "is responsible to third persons for the negligence of his agent in the transaction of the business of the agency." Courts apply the same idea to employers and employees under the doctrine of respondeat superior.
The California Supreme Court explained the reasoning in Hinman v. Westinghouse Electric Co. (1970) 2 Cal.3d 956: the employer is better able to absorb losses and spread them "through prices, rates or liability insurance." In other words, the law expects the business to carry insurance for this.
In practice, if your employee is on a work errand when they rear-end someone, the plaintiff's attorney will name your company. Your company has the assets and, ideally, the insurance.
The commute usually isn't covered, but there are exceptions
Under the "going and coming" rule, an employee driving to and from work is ordinarily outside the scope of employment (Hinman). The exceptions matter, though:
Paid travel time. In Hinman, the employer paid travel time and travel expenses, and the court held the commute was within the scope of employment.
The vehicle-use exception. California's civil jury instruction CACI No. 3725 tells jurors that if an employer requires an employee to drive to and from work so the vehicle is available for the employer's business, the drive is within the scope of employment. The requirement can be express or implied.
So a field technician who is expected to drive their own truck to job sites can expose your company even on the way to the first stop.
Vehicle Code §17150 is about owners, not employers
Vehicle Code §17150 is often cited in articles about employer liability, but it makes the owner of a motor vehicle liable for injuries caused by anyone driving it with the owner's permission. Section 17151 caps that owner-only liability at $15,000 per person, $30,000 per accident for injury, and $5,000 for property damage. The cap applies only where liability does not arise through a principal-agent or employer-employee relationship.
What that means for you:
If your employee drives their own car, your business isn't the owner, so §17150 doesn't apply to you. Your exposure comes from respondeat superior, which has no statutory cap.
If your employee drives a car your business owns, you are the owner. The employer-employee relationship takes you outside the §17151 cap. That situation calls for a commercial auto policy, not HNOA alone.
Rental cars: the rental company is usually off the hook
Federal law (49 U.S.C. §30106, the Graves Amendment) generally shields companies in the business of renting or leasing vehicles from owner-based liability for crashes during the rental period, as long as the rental company itself wasn't negligent. If your employee causes a serious crash in a rental, the claim generally won't stop at the rental company. It comes to the driver and to your business. That's the hired-auto half of HNOA.

Why the employee's personal auto policy may not protect your business
The employee's personal auto policy is typically the first policy to respond when they're driving their own car. Owners often stop thinking about it there. Four problems:
Limits may be low. California's minimum liability limits rose to $30,000 per person, $60,000 per accident and $15,000 for property damage for policies issued or renewed on or after January 1, 2025 (Vehicle Code §16056). A crash with serious injuries can exceed that quickly. Once the employee's limit is exhausted, the plaintiff looks to your business for the rest.
Some business uses may be excluded. Personal auto policies vary. Some limit or exclude coverage for certain business activities, such as carrying property or people for a fee. Whether a specific errand is covered depends on the employee's policy wording, which you've probably never seen.
The policy may have lapsed. You won't know unless you check.
The personal policy defends the employee, not you. Even when it pays, your company may still be named in the suit and need its own defense.
And your general liability policy excludes autos
The standard commercial general liability form (ISO CG 00 01) excludes bodily injury and property damage "arising out of the ownership, maintenance, use or entrustment to others of any aircraft, 'auto' or watercraft owned or operated by or rented or loaned to any insured." Employees are insureds under that form while acting for your business. So an employee driving on a work errand generally falls outside your GL coverage, whoever owns the car. Your general liability policy was never built to cover driving. HNOA is the piece that does.
What HNOA typically covers, and what it doesn't
Situation | Covered by HNOA? | What responds instead |
Employee on a work errand in their own car injures another driver; your business is sued | Typically yes (your company's liability) | Employee's personal auto usually pays first |
Employee in a rental car on a business trip damages another vehicle | Typically yes (liability) | — |
Damage to the rental car itself | Typically no. Standard HNOA endorsements exclude damage to property rented or loaned to the insured. | Hired auto physical damage coverage on a commercial auto policy, the rental company's damage waiver, or a corporate card benefit (check terms) |
Damage to the employee's own car | No | Employee's own collision/comprehensive coverage |
Employee hurt in the crash | No | Workers' compensation (see our workers' comp guide) |
Vehicles your business owns or leases long-term | No | Commercial auto policy |
The employee's personal liability for their own car | Usually no. Standard forms don't make the employee an insured for a car they or their household own. | Employee's personal auto policy |
Two details deserve attention:
HNOA protects the business, not the employee. Under the ISO business auto form, your employee is not an insured for a covered auto they or their household own. The ISO BOP endorsement likewise excludes the owner of a non-owned auto from its definition of insured. Your HNOA defends your company. The employee relies on their own policy.
HNOA is usually excess. The ISO BOP endorsement states that it is excess over any primary insurance covering the hired or non-owned auto. Expect HNOA to sit on top of the vehicle's own policy rather than replace it.
How HNOA is added: BOP, general liability or commercial auto
HNOA is rarely sold on its own. It's attached to a policy you already carry. Where it goes depends on whether your business owns vehicles.
Your situation | Where HNOA usually goes | How it works |
No owned vehicles, and you have a BOP | BOP endorsement (ISO form BP 04 04, Hired Auto and Non-Owned Auto Liability, or a carrier equivalent) | Hired and non-owned liability are each activated only if a premium is shown for them. Check that both are scheduled. |
No owned vehicles, and you have a standalone GL policy | Carrier endorsement to the GL, or a separate small policy | Wording varies by carrier. Some write it as a GL endorsement, others require a business auto policy. |
You own or lease vehicles | Commercial auto policy using covered-auto symbol 8 (hired autos) and symbol 9 (non-owned autos) on the ISO Business Auto Coverage Form (CA 00 01) | Liability for hired and non-owned vehicles is added to the same policy that covers your fleet. Hired auto physical damage can be added separately. |
If you're deciding between a BOP and a standalone GL policy, read BOP vs general liability. Adding HNOA is often one of the easiest wins in a business owner's policy (BOP). If your company does own vehicles, start with commercial auto insurance for business vehicles and when you need a commercial auto policy.
Check your umbrella, too
If you carry umbrella insurance, confirm the umbrella lists your HNOA coverage as underlying insurance. Many umbrellas only sit over auto liability that's scheduled underneath them. If HNOA isn't scheduled, the umbrella may not drop down over it. Our guide to commercial umbrella vs excess liability explains how that stacking works.
Who needs HNOA
If anyone drives for your business in a vehicle your business doesn't own, you have the exposure. That includes office staff driving to the bank or a client meeting, trades employees driving personal trucks to the supply house, restaurant catering drop-offs, home-health visits, nonprofit volunteers picking up donations, and any business that rents vehicles for trips or trade shows. A solo owner driving a personal car is a separate issue (see home-based business insurance). Once you hire someone who drives, HNOA becomes relevant.
Reducing the risk (and the premium)
HNOA is priced on factors like how many employees drive, how often, how far and for what purposes. A sensible employee-driving policy lowers your risk and makes your business easier to insure.
Write a short vehicle-use policy: who may drive for work, for what, and what's prohibited.
Collect proof of insurance from every employee who drives for work, and set a minimum liability limit you expect them to carry. Re-collect at each renewal.
Check driving records for employees who drive regularly, with their consent and in line with applicable law.
Reimburse mileage. Labor Code §2802 requires employers to reimburse employees' necessary expenditures incurred in direct consequence of their duties, and the California Supreme Court has applied it to employees' costs of using their own cars for work (Gattuso v. Harte-Hanks Shoppers, Inc. (2007) 42 Cal.4th 554). That's a wage-and-hour obligation, not insurance, but the records also show which trips were business trips.
Decide your rental-car approach in advance. Either buy the rental company's damage waiver, rely on a corporate card benefit you've confirmed in writing, or add hired auto physical damage to a commercial auto policy. HNOA liability alone won't fix a dented rental.
Report every accident promptly, even minor ones, to your agent. Late notice is one of the easiest ways to lose coverage. If you're sued, see what to do when a customer sues your business. The first steps are similar for auto claims.
FAQs
What is hired and non-owned auto insurance?
HNOA is liability coverage for your business when an employee or owner drives a vehicle your business doesn't own (their personal car, a rental or a borrowed vehicle) on company business. It pays your company's defense and damages if the driver injures someone or damages their property. It typically does not cover damage to the vehicle itself.
Do I need HNOA if my employees have their own car insurance?
Usually, yes. The employee's policy protects the employee, often at limits as low as California's minimum ($30,000/$60,000/$15,000 for policies issued or renewed on or after January 1, 2025). If the claim exceeds those limits, or the personal policy excludes the use, the injured party can pursue your business directly. HNOA typically sits excess over the employee's policy to protect your company.
Does general liability cover employees driving their own cars for work?
Generally no. The standard GL form excludes injury and damage arising from the use of autos owned or operated by, or rented or loaned to, any insured, and employees are insureds while working for you. HNOA is how businesses fill that gap.
Does hired auto coverage pay for damage to a rental car?
Not usually. Standard HNOA endorsements cover your liability to others and exclude damage to property rented to you. For damage to the rental itself, you need hired auto physical damage on a commercial auto policy, the rental company's damage waiver, or a confirmed corporate card benefit.
Can I add HNOA to a business owner's policy?
Yes, in most cases. Many BOPs offer a hired and non-owned auto liability endorsement (the ISO version is BP 04 04). Make sure both the hired and non-owned parts show a premium on your declarations, because each is activated separately.
