Employees driving their own cars for work: who is liable?
When an employee crashes a personal car on a work errand, driver and employer can both be liable. Whose insurance pays first, the gaps and a policy to adopt.
When an employee causes a crash in a personal car while doing the employer's work, both can be liable. The employee answers for his or her own negligence, and the employer can answer for it too if the driving was within the scope of the job. The employee's personal auto policy usually pays first, and the employer's hired and non-owned auto (HNOA) coverage, if the business bought it, usually sits behind it. If the business has neither HNOA nor an umbrella that reaches non-owned autos, the company pays out of pocket.
Why an employer can be liable
The doctrine is respondeat superior: an employer is responsible for the torts of an employee committed within the scope of employment. The California Supreme Court explained the rationale in Hinman v. Westinghouse Electric Co., 2 Cal.3d 956 (1970): losses caused by employees' torts, which are sure to occur in running the enterprise, are placed on the enterprise "as a required cost of doing business." The rule does not depend on who owns the car. What matters is whether the trip was part of the work.
Two further theories can sit alongside it. Negligent hiring, retention and entrustment claims argue the employer knew or should have known the employee was an unsafe driver, which is why Driver selection, MVRs and your commercial auto premium matters for office staff and salespeople too. And an employer that directs how the trip is made, or sets a schedule that pushes people to hurry, may be sued for its own conduct.
Commutes, errands and the "required vehicle"
Courts generally apply a "going and coming" rule: ordinary travel between home and a fixed workplace is outside the scope of employment, so the employer is not liable for commuting crashes. Exceptions turn on the facts. Errands for the employer during the day are usually inside the scope. A special trip at the employer's request can be. And a number of states recognize an exception where the employer requires, or comes to rely on, the employee's use of a personal vehicle for work.
New Jersey's Supreme Court applied that exception in Carter v. Reynolds, 175 N.J. 402 (2003), where an employer's requirement that an employee use her own car on mandatory client visits subjected the employer to liability for her driving. Maryland's highest court addressed an employer's liability for an employee driving his own car to his usual workplace in Oaks v. Connors, 339 Md. 24 (1995), a reminder that outcomes differ by state. California courts have also developed a "required-vehicle" or incidental-benefit exception. The point for a business owner is not to memorize cases. The more your job depends on the employee's car, the more likely a court will treat the driving as yours. State law differs here; see California, New Jersey and an attorney who handles employment and tort law in your state.
Whose insurance pays, in order
The sequence below describes the usual structure of the standard forms. Your policies and state law may change it.
| Layer | Who it protects | What to know |
|---|---|---|
| Employee's personal auto policy | The employee, and often the employer as someone legally responsible for the employee's driving | Generally primary. Personal auto forms usually cover business use of a private passenger car, but exclude carrying persons or property for a fee, which matters for delivery work |
| Employer's HNOA or "non-owned auto" liability | The business | Typically excess over the employee's own insurance. The employee is not an insured on the business auto form for a car the employee owns, unless the policy adds ISO endorsement CA 99 33, Employees as Insureds |
| Employer's umbrella or excess policy | The business | Check whether it follows form over non-owned autos; some are written only over scheduled underlying policies |
| Employer's general liability | Not the auto exposure | The CGL excludes autos, so it will not respond. See CGL exclusions: what a general liability policy does not cover |
Two of those points deserve detail.
The employee is not automatically an insured. The standard business auto form carves out the employee's own car from "who is an insured." The CA 99 33 endorsement fixes that, per a form summary at InsuranceXDate: liability only, with the employee's personal policy remaining primary and the endorsement applying only after its limits are exhausted. It does not pay for damage to the employee's car.
The employer's protection is usually excess. The other insurance clause in the business auto form makes coverage for autos you do not own excess over other collectible insurance. That is the point of Hired and non-owned auto (HNOA) coverage: what it covers and who needs it: it protects the business when the employee's limits are too low, or when the employee's insurer denies the claim.
Where the gaps are
- Low limits. An employee may carry only the state minimum, and a serious injury claim can exceed it quickly. The employer's HNOA and umbrella are then what the plaintiff reaches for. A written minimum limit for any employee who drives on the job, with proof of insurance each year, closes part of the gap.
- No HNOA at all. Some businesses assume a general liability policy or a personal policy will do. Neither will respond for the business.
- Delivery and for-hire use. An employee delivering food or goods in a personal car can fall into a livery or fee-based exclusion in the personal policy and a delivery restriction in the employer's HNOA. See insurance for delivery businesses and gig drivers.
- Regular-use vehicles. If you provide a car, allowance or lease and the employee uses it daily for the business, the carrier may want it scheduled as a covered auto instead of treated as non-owned.
- Physical damage. HNOA is liability only. The employee's own collision coverage pays for the employee's car, and a deductible dispute with the employer is common.
- Injuries to the employee. Workers' compensation, not auto insurance, handles those when the driving is within the course of employment. State rules on commuting differ.
- Volunteers and family members. A volunteer who drives for a charity or a family member who borrows the car for the errand creates the same exposure with less paper.
Reimbursement is not insurance
Paying mileage does not transfer risk, but it affects the "required vehicle" analysis and the employee's willingness to carry adequate limits. The IRS standard mileage rate for business use in 2026 is 72.5 cents per mile for January 1 through June 30 and 76 cents per mile for July 1 through December 31 (IRS standard mileage rates). That rate is a tax convenience, not a coverage measure. Some states require employers to reimburse necessary business expenses, and California Labor Code § 2802(a) says an employer "shall indemnify his or her employee for all necessary expenditures or losses," a duty that reaches expenses the employee incurs in direct consequence of doing the job. Check your state.
A hypothetical accident
Say a regional sales rep driving his own car to a client meeting rear-ends a motorcyclist, who is badly hurt. The rep's personal policy carries low liability limits of $50,000 per person. The motorcyclist's lawyer values the claim at $600,000 and sues the rep and the company. The employer asserts it had no vehicle on the road, but the trip was a scheduled client visit, so scope of employment is hard to dispute. The rep's insurer pays its $50,000 first. The company's HNOA liability then responds as excess, up to its limit, and the company's umbrella may follow. The numbers are invented, but the order of payment is the point: the employer pays less, and later, if it bought HNOA with adequate limits, and carries the entire excess balance if it did not.
A policy worth adopting
A short written policy changes both the risk and the evidence. Include:
- Who may drive on company business, and the requirement for a valid license and an acceptable MVR.
- Minimum personal auto liability limits, and proof of insurance on hire and each year.
- Vehicle condition and maintenance expectations.
- No handheld phone use, and rules on hurrying or driving fatigued.
- Immediate accident reporting to a named person, and what to do at the scene. See what to do after an accident in a company vehicle.
- How mileage is reimbursed.
- Written acknowledgement that personal use of the car is separate from business use.
Then buy the matching coverage: HNOA with limits to fit your exposure, an umbrella that follows form over it, and, if the roles call for it, the Employees as Insureds endorsement. Your broker can use the What business insurance do I need? to compare against your current program. The wider structure is in commercial auto insurance: what it covers and what it leaves out and business auto coverage symbols explained: what each number covers.
Key takeaways
- Both the employee and the employer can be liable. The employer's exposure depends on scope of employment, and a job that depends on the employee's personal car pushes toward liability in states that recognize a required-vehicle exception.
- The employee's personal auto policy is usually primary, and the employer's HNOA coverage usually sits excess. The employee is not an insured on the employer's policy unless
CA 99 33is added. - General liability does not cover auto accidents. Without HNOA, the business pays the excess itself.
- Delivery use, low personal limits and regular-use vehicles are the common gaps.
- A written driver policy with minimum limits, MVR standards and accident reporting is cheap and shapes both coverage and defense.
