You were hit by a vehicle owned by a company. Maybe a delivery van, a contractor’s truck, a sales rep’s company car, a rideshare driver. Maybe the at-fault driver tells you “talk to my boss” or “the company will handle it.” Maybe the boss tells you something different.
Three potential insurance layers apply in commercial vehicle accidents under Arizona law, and the at-fault driver and their employer often have conflicting incentives. Understanding the layers is the first step to getting your bills paid.
The three coverage layers
Layer 1: The at-fault driver’s personal auto insurance
Every Arizona driver is required to carry minimum liability coverage under A.R.S. § 28-4009: $25,000 per person, $50,000 per accident, $15,000 property damage. This is the first layer. But many personal policies have business use exclusions that void coverage when the vehicle is being used for work. If the driver was on the clock when the crash happened, their personal policy may deny coverage entirely.
Layer 2: The employer’s commercial auto policy
Most employers who allow employees to drive company vehicles or use personal vehicles for work carry commercial auto insurance. These policies typically have much higher limits than personal policies — often $500K to $1M per occurrence, sometimes more for vehicles classified as commercial trucks under federal regulations.
Under Arizona’s vicarious liability rules (and the common law doctrine of respondeat superior), an employer is liable for the negligence of an employee acting within the scope of employment. This means even if the driver had no fault attribution at all, the employer’s commercial policy can pay because the driver was on the job.
Layer 3: Your own coverage layers
Med pay (immediate, regardless of fault), UM/UIM (if the commercial policy denies or is insufficient), and any umbrella policy you carry.
The “scope of employment” question
The critical legal question in commercial vehicle cases: was the at-fault driver acting within the scope of their employment at the time of the crash?
Arizona courts look at factors including:
- Was the driver on the clock?
- Was the vehicle being used for company business?
- Was the route reasonable for the work assignment?
- Did the driver have authorization to use the vehicle?
- Was the activity within the type of work the employee was hired to do?
Even minor deviations (“frolic and detour”) can sometimes keep the case within scope. A delivery driver who stops at a coffee shop on the way to a delivery is typically still within scope. A sales rep driving home from a client meeting is typically within scope. A salaried executive driving a company-owned vehicle to a personal weekend trip is typically outside scope.
The employer will fight scope hard because it determines whether their commercial policy is on the hook. Discovery matters: time records, GPS data, dispatch logs, expense reports.
When the company refuses to pay your hospital bill
You may encounter a situation where:
- The at-fault driver tells you “my boss will pay” or “the company is handling it”
- The company’s insurance won’t take your calls or denies you exist
- Your medical bills are mounting and no payments are arriving
This is unfortunately common. The company has every incentive to delay until you either give up or settle for less than full value. Steps to take:
- Send a written claim letter identifying the at-fault driver, the company, the date and circumstances of the crash, and a demand for the commercial policy information. Certified mail with return receipt.
- Request the police report if you don’t have it. Commercial vehicle crashes have specific information requirements under A.R.S. § 28-666 that documentation may be useful.
- Use your own coverage in the meantime. Med pay if you have it — pays bills immediately regardless of fault dispute. Health insurance if not. Avoid going to collections.
- Consult an attorney before signing anything from the company or their insurer. Particularly any “limited release” or “interim settlement” — those often have language that releases the whole claim.
Commercial vehicle = different regulations apply
If the at-fault vehicle is a commercial truck (semi, box truck, large delivery vehicle) or qualifies under federal motor carrier regulations, additional rules apply:
- Federal Motor Carrier Safety Administration (FMCSA) regulations govern hours of service, vehicle maintenance, driver qualifications, drug testing, and crash records.
- Higher minimum insurance requirements — federally regulated commercial trucks typically carry $750,000 to $1M minimum (and often much more for HAZMAT or larger vehicles).
- Black box / ELD data — electronic logging devices record driving hours, speed, hard braking events. This is critical evidence that must be preserved promptly via spoliation letter.
- Drug and alcohol testing requirements after crashes — failure to test can be evidence of corporate negligence.
When the driver was the company owner
Special case: if the at-fault driver is the owner of the company (e.g., a small contractor in their company-branded truck), the personal vs. commercial line gets blurry. Courts look at:
- Whether the vehicle is titled in the company name
- Whether the business deducts the vehicle as a business expense
- What insurance was purchased for it
- What the driver was actually doing at the time
Owner-operated small business defendants often have minimal coverage, but personal asset attachment may be possible in serious cases.
Arizona-specific procedural notes
Standard Arizona personal injury rules apply:
- 2-year statute of limitations under A.R.S. § 12-542
- Pure comparative negligence under A.R.S. § 12-2505
- If a government employer is involved (city employee in city vehicle, etc.), the 180-day notice rule under A.R.S. § 12-821.01 applies — much shorter than the standard 2 years
Frequently asked questions
Q: The driver gave me their personal insurance card, not the company’s. Is that the right insurance?
Maybe. The personal policy is the first layer. The company’s commercial policy is the second layer that often applies in addition. Both should be identified and pursued.
Q: The company is out of state. Can I still sue them here?
Generally yes. Arizona’s long-arm statute allows jurisdiction over out-of-state defendants whose conduct caused harm in Arizona. The case typically proceeds in Arizona court.
Q: My medical bills are over $50,000 and the personal policy is $25,000. What now?
That’s exactly the scenario where the commercial policy layer becomes critical. Identifying it and getting their adjuster engaged is the key move. Your own UIM is a backup if commercial coverage is unavailable.
Q: The driver said the company forbade them from using the vehicle for personal trips, but they were using it personally when they hit me. Does the company still pay?
Possibly. Courts look at whether the use was foreseeable and whether the company had effective controls. Even when the use violated written policy, the company can sometimes still be liable under negligent entrustment or other theories.
Q: Should I file a workers’ comp claim if I was also working at the time of the crash?
Possibly — and importantly, you may have both a workers’ comp claim AND a third-party PI claim against the at-fault driver/company. They’re not mutually exclusive. An attorney evaluates which routes apply.
