STATE LAW – ARIZONA LIBRARY – GUIDE 14
Work, Employer & Commercial Vehicle Coverage
How Arizona separates employer tort liability, commercial-auto coverage, employee use of personal or non-owned vehicles, workers’ compensation, and special financial-responsibility rules for regulated commercial transportation.
A work-related crash can involve several different legal systems at once.
Do not ask only whether the driver was “working.” Arizona requires separate analysis of:
(1) whether the employer is vicariously liable for the employee’s driving,
(2) whether a commercial or personal auto policy covers the driver and vehicle,
(3) whether workers’ compensation applies to an injured employee, and
(4) whether special commercial-transportation financial-responsibility rules apply.
CURRENT-LAW UPDATE · CRAVENS
Cravens v. Montano holds that an employee uses a non-owned vehicle “in connection with” the employer’s
business when the use is directly involved with, or in furtherance of, the employer’s business purpose.
A routine commute to or from the employer’s office does not satisfy that policy-language formulation.
01
RESPONDEAT SUPERIOR
Employer liability turns on the employee’s scope of employment at the time of the crash
Under Arizona respondeat-superior law, an employer may be vicariously liable for an employee’s negligent driving when
the employee is acting within the scope of employment. The inquiry focuses on the employee’s work and the employer’s
control or right to control the conduct at the time of the accident.
Engler control test
Engler v. Gulf Interstate Engineering, Inc. adopts Restatement (Third) of Agency § 7.07 for Arizona.
An employee acts within the scope of employment when performing assigned work or engaging in conduct subject to
the employer’s control.
Independent personal course
Conduct falls outside the scope when the employee is on an independent course of action that does not further
the employer’s purposes and is not within the employer’s control or right to control.
Travel reimbursement is not enough by itself
Engler explains that reimbursement of travel expenses or a travel allowance, without more, does not automatically
place personal travel within the scope of employment.
Assess control at the time of the crash
Ask what the employee was doing when the tort occurred—not merely why the employee happened to be away from home,
using a company-paid vehicle, or traveling on a work assignment.
DO NOT SUBSTITUTE WORKERS’ COMPENSATION LAW
Engler expressly distinguishes workers’ compensation from tort respondeat superior. Workers’ compensation is a
no-fault employee-benefit system and can use a broader work-related inquiry; third-party tort liability is tied to
the employer’s control or right to control at the time of the negligent act.
02
COMMERCIAL AUTO COVERAGE
Coverage is a contract question separate from employer tort liability
A commercial-auto policy may cover vehicles the business owns, hires, leases, borrows, or does not own, depending on the
policy’s declarations, covered-auto designations, insured definitions, and endorsements.
A
Owned vehicles
Identify company-owned autos and whether the accident vehicle is scheduled or otherwise included within the policy’s covered-auto designation.
B
Hired autos
Check vehicles the business rents, leases, hires, or borrows and the exact policy definition or endorsement controlling that class.
C
Non-owned autos
Check employee-owned or other vehicles used in connection with the business and any non-owned-auto endorsement or covered-auto provision.
D
Who is an insured?
Determine whether the employee, employer, vehicle owner, permissive user, or additional insured qualifies under the specific coverage provision.
E
Other insurance
Compare the commercial policy with the employee’s personal policy, rental coverage, umbrella/excess coverage, and any other applicable insurance.
SEPARATE QUESTIONS
The employer can lack vicarious tort liability yet an employee may still qualify for insurance coverage under the
policy’s wording—or vice versa. Analyze tort responsibility and contractual insured status independently.
03
2025 CURRENT-LAW UPDATE
Cravens: employee use of a non-owned auto “in connection with” the business
Cravens v. Montano is the current Arizona Supreme Court authority for the commercial-auto policy language
considered there. The policy extended coverage to an employee using a non-owned covered auto in connection with and in
the employer’s business.
Directly involved with the business
Vehicle use qualifies when it is directly involved with the employer’s business purpose.
In furtherance of the business
The Court also recognizes coverage when the vehicle use advances or furthers the employer’s business purpose under
the policy wording before it.
Routine commute excluded
A routine commute to or from the employer’s office does not satisfy the Court’s “in connection with your business”
standard.
POLICY-SPECIFIC HOLDING
Cravens interprets Cincinnati’s policy language. It does not establish that every commercial-auto policy uses the same
wording or that every trip with some work connection is covered. Read the actual commercial policy first.
CROSS-TOPIC LINK
Cravens also addresses a contingent Morris agreement. That separate holding belongs in CLM-040 — Settlement, Releases
& Finality and should not be confused with the commercial-auto coverage holding summarized here.
04
EMPLOYEE’S PERSONAL VEHICLE
Using a personal vehicle for work can create overlapping coverage
Employee’s personal auto policy
Determine whether the employee’s personal policy covers the trip and whether any business-use, commercial-use,
delivery, livery, rideshare, regular-use, or other exclusion applies.
Employer’s non-owned-auto coverage
Determine whether the employer’s commercial policy includes employee-owned vehicles used in the employer’s business
and whether the employee qualifies as an insured under that provision.
BUILD BOTH POLICY FILES
Do not decide priority from a single declarations page. Obtain the employee’s complete personal policy and the employer’s
complete commercial policy, then compare insured status, exclusions, and other-insurance provisions.
05
INJURED EMPLOYEE
Workers’ compensation changes the employee’s remedies but does not replace the auto-insurance analysis
Exclusive remedy against employer
A.R.S. § 23-1022 generally makes workers’ compensation the employee’s exclusive remedy against the employer and a
co-employee acting within the scope of employment, subject to the statute’s exceptions.
Third-party claim can remain
A.R.S. § 23-1023 preserves an injured employee’s claim against a negligent third person not in the same employ and
creates statutory rights for the workers’ compensation carrier or self-insured employer.
DIFFERENT “SCOPE” ANALYSES
Whether an injury is work-related for workers’ compensation does not automatically decide whether the employer is
vicariously liable to a third-party crash victim. Engler expressly explains that the two systems serve different purposes.
06
REGULATED COMMERCIAL TRANSPORTATION
Some commercial operations have higher statutory financial-responsibility requirements
A.R.S. § 28-4033 imposes specified combined-single-limit liability requirements on persons subject to Arizona’s
transportation-financial-responsibility article. The amounts vary by operation—for example, property transport,
passenger capacity, and hazardous materials.
Property transportation
Certain heavier vehicles transporting nonhazardous property are subject to higher combined-single-limit requirements.
Passenger transportation
Passenger vehicles subject to the article can have substantially higher liability and UM requirements depending on seating capacity.
Hazardous materials
Transportation of specified hazardous materials, substances, or wastes can trigger $1 million or $5 million statutory requirements.
NOT EVERY BUSINESS VEHICLE
Section 28-4033 applies to persons and operations subject to that article; it is not a universal minimum-limit statute
for every automobile owned by every Arizona business.
07
PRACTICAL METHOD
Audit a work-vehicle crash in layers
1
Identify every actor
Driver, employer, vehicle owner, lessee, contractor, client, passenger, and any other entity connected to the trip.
2
Reconstruct the employee’s task
What was assigned? Where was the employee going? Who controlled the route, timing, vehicle, and purpose?
3
Test tort scope of employment
Apply Engler and current Arizona respondeat-superior authority to the employee’s conduct at the exact time of the crash.
4
Build the insurance stack
Commercial auto, personal auto, hired/non-owned auto, fleet, umbrella/excess, rental, and any other applicable coverage.
5
Apply Cravens where relevant
If the commercial policy uses materially comparable non-owned-auto/business-use wording, analyze whether the use directly involved or furthered the employer’s business.
6
Check workers’ compensation
If an employee was injured, analyze § 23-1022 exclusivity and § 23-1023 third-party rights separately from tort scope.
7
Check special commercial limits
Determine whether the operation is subject to § 28-4033 or another transportation-specific financial-responsibility statute.

VERIFICATION
Formal QC for a work-vehicle conclusion
- Identify who employed the driver and who owned the vehicle.
- Document the employee’s assigned work, route, destination, timing, and actual purpose at the moment of the crash.
- Identify the employer’s control or right to control the employee’s driving activity.
- Do not use workers’ compensation “course and scope” as a substitute for Engler’s tort analysis.
- Obtain the complete commercial-auto policy, not only the declarations.
- Identify owned, hired, borrowed, and non-owned-auto provisions and endorsements.
- Obtain the employee’s personal auto policy if the employee-owned vehicle was involved.
- If relying on Cravens, compare the actual policy wording before applying its business-use rule.
- For an injured employee, separately analyze §§ 23-1022 and 23-1023.
- Use § 28-4033 only if the commercial operation is actually subject to that transportation-financial-responsibility article.
QC STATUS
Engler and Cravens were checked against official Arizona Supreme Court opinions. A.R.S. §§ 23-1022, 23-1023,
28-4009, and 28-4033 were checked against the current Arizona Legislature compilation on September 26, 2026.

COMMON QUESTIONS
Questions to ask
Is an Arizona employer automatically liable whenever an employee causes a crash while driving for some work-related reason?
No. Engler requires a scope-of-employment analysis focused on the employee’s conduct and the employer’s control or right to control at the time of the accident.
Does the employer’s payment for gas, rental car, meals, or travel automatically establish employer liability?
No. Engler explains that travel reimbursement or an allowance, without more, does not itself establish scope of employment.
If the employer is not vicariously liable, can its commercial auto policy still cover the employee?
Potentially. Tort liability and contractual insured status are separate questions. The answer depends on the commercial policy’s actual wording and facts.
What did Cravens change for Arizona commercial-auto coverage?
Cravens clarified the policy phrase “in connection with your business” for the non-owned-auto coverage before the Court: the employee’s vehicle use must be directly involved with or in furtherance of the employer’s business purpose, and a routine commute is excluded.
Does an employee’s own personal auto policy disappear when the employee drives for work?
No universal rule should be assumed. Read the personal policy for business-use and other exclusions and the employer’s commercial policy for hired or non-owned-auto coverage and other-insurance provisions.
If the injured person is the employee, is workers’ compensation the only possible source of recovery?
Workers’ compensation is generally exclusive against the employer and qualifying co-employees under § 23-1022, but § 23-1023 preserves specified claims against negligent third persons not in the same employ.
Do the high commercial limits in § 28-4033 apply to every company car?
No. Section 28-4033 applies to persons and transportation operations subject to that article. Ordinary business-owned autos may instead be governed by other financial-responsibility and policy rules.
