Montana Employer, Commercial & Work-Use Vehicles

A work-related crash presents two different investigations

Montana respondeat superior turns on the employee's conduct

Montana imposes vicarious liability on an employer for tortious employee conduct committed within the scope of employment.

MCA § 28-10-602 embodies Montana's agency rule concerning a principal's responsibility to third persons for an agent's negligence and wrongful conduct in the transaction of the agency's business.

Modern Montana cases describe conduct as potentially within the scope of employment when it is:

• expressly authorized by the employer;
• implicitly authorized by the employer; or
• sufficiently incidental to expressly or implicitly authorized work.

Scope of employment is usually fact-intensive

Brenden: unauthorized conduct can still be within the employment relationship

In Brenden v. City of Billings, 2020 MT 72, 399 Mont. 352, 470 P.3d 168, the Montana Supreme Court explained that conduct can remain within the scope of employment even when the employer did not specifically authorize the wrongful act.

Relevant considerations include:

• whether the conduct was of a type employees commonly perform
• the time and place of the conduct
• the purpose of the conduct
• whether the employer could reasonably expect similar conduct
• the extent of departure from authorized work
• whether the employer furnished the instrumentality involved
• whether the employee was at least partly serving the employer's interest

L.B.: mixed motives do not automatically take conduct outside employment

L.B. v. United States, 2022 MT 166, 409 Mont. 505, 515 P.3d 818, further emphasized that scope is not reduced to the question whether the employer approved the wrongful conduct.

An employee may act with mixed motives. Montana asks whether the wrongful conduct arose out of and was sufficiently connected with the authorized task the employee was performing.

T.M.B.: recent confirmation of the fact-intensive rule

T.M.B. v. West Mont, 2024 MT 319, recently restated Montana's scope-of-employment principles and described the inquiry as necessarily fact-intensive.

The Court did not decide a respondeat-superior claim on the merits in T.M.B.; the case centered on a separate nondelegable-duty theory. It is useful here as a recent synthesis, not as a motor-vehicle holding.

A personal automobile can still be used within the scope of employment

Ownership of the automobile does not decide respondeat superior.

Webster: work can create the need for travel in a personal car

In Webster v. Mountain States Telephone & Telegraph Co., 108 Mont. 188, 89 P.2d 602 (1939), a telephone-company employee was traveling to perform work while using his own automobile.

Montana recognized that when the employment itself creates the necessity for travel, use of a personally owned automobile can occur within the scope of employment.

Evidence that can indicate a work trip

• employee was on the clock
• travel time was paid
• mileage was reimbursed
• employer directed the destination
• employee was traveling between job sites
• employee was making a delivery
• employee was obtaining supplies
• employee was transporting customers
• employee was transporting coworkers
• employee was carrying business equipment
• employee was responding to a work call
• employee was attending an off-site meeting
• personal-vehicle business use was customary
• management knew of that customary use

Employment status alone is not enough

An employee can plainly remain employed while nevertheless driving on an independent personal mission outside the scope of that employment.

Bowyer: a personal excursion fell outside employment as a matter of law

In Bowyer v. Loftus, 2008 MT 332, the employee's work sometimes required him to transport members of his drilling crew in his personal vehicle.

But at the time of the crash:

• his shift had ended more than five hours earlier;
• he was not being paid;
• he was not receiving mileage compensation;
• he was not transporting his crew;
• he was returning from dinner, sightseeing and bar stops; and
• the travel was not undertaken at the employer's request.

Montana held that only one reasonable inference could be drawn: the driver was outside the scope of employment.

Company ownership of the vehicle is evidence—not the final tort answer

A company-owned vehicle can strongly support further investigation of employment, authorization and commercial insurance.

It does not automatically establish that every trip in the vehicle occurred within the employee's scope of employment.

Commercial auto insurance requires its own contract analysis

When a business owns, leases, hires or regularly uses vehicles, a commercial automobile policy may be the principal source of liability insurance.

Review the policy for:

• named insured entity
• covered-auto symbols
• scheduled autos
• owned autos
• hired autos
• non-owned autos
• temporary substitutes
• employee-as-insured provisions
• permissive users
• trailers
• loading and unloading
• liability limits
• UM/UIM provisions
• MedPay
• other-insurance clauses
• endorsements
• umbrella and excess schedules

Being a listed driver does not make someone an insured for every coverage

American States v. Flathead Janitorial

American States Insurance Co. v. Flathead Janitorial & Rug Services, Inc., 2015 MT 239, involved a commercial automobile policy issued to a corporation.

The injured claimant was a daughter of the corporate owners and had been listed as a driver in insurer correspondence. She sought UIM and MedPay benefits after being injured while riding a bicycle.

The Montana Supreme Court held that she was not an insured for those coverages because:

• the named insured was the corporation;
• the policy definitions governing UIM and MedPay controlled;
• she was not employed by the corporation at the time; and
• she was not occupying a covered company auto.

A business may have several liability layers

High Country Paving shows why the entire insurance program matters

High Country Paving, Inc. v. United Fire & Casualty Co., 2019 MT 297, arose from a catastrophic crash involving an employee driving a company truck pulling an equipment trailer.

The employer's insurance program included:

• $1 million commercial automobile liability coverage;
• $2 million commercial umbrella coverage; and
• separate commercial general liability coverage.

The commercial auto and umbrella policies together supplied $3 million toward the motor-vehicle loss.

The CGL policy did not automatically provide another auto layer

In High Country Paving, Inc. v. United Fire & Casualty Co., 2022 MT 72, the Montana Supreme Court considered the separate CGL coverage dispute arising from the same crash.

The Court confirmed that unambiguous exclusions or limitations can remain enforceable where invalidating them would expand the risk beyond the insurance the carrier actually assumed.

An employee-owned automobile used for work can create hidden coverage

A personally owned vehicle may be involved in the employer's business when the employee uses it to:

• make deliveries
• visit customers
• carry tools or supplies
• travel between job sites
• transport coworkers
• run an employer errand
• attend an off-site meeting
• perform sales activity
• respond to an employer request

Potential insurance sources can include both:

Direct employer negligence is separate from respondeat superior

Respondeat superior imposes derivative responsibility based on an employee's conduct within the employment relationship.

Depending on the facts and applicable law, a business may also face claims based on its own conduct, such as:

• negligent vehicle entrustment
• negligent hiring
• negligent supervision
• negligent retention
• unsafe vehicle maintenance
• unsafe loading
• failure to train
• other independently negligent business conduct

Williams: negligent entrustment requires legal control

In Williams v. State Medical Oxygen & Supply, Inc., 265 Mont. 111, 874 P.2d 1225 (1994), Montana recognized a potential negligent-entrustment theory involving a company pickup supplied for use under circumstances that allegedly created an unreasonable risk.

The decision emphasizes that negligent entrustment rests on meaningful legal control over the vehicle—not merely physical ability to stop another person from driving.

Regulated motor carriers can have additional insurance requirements

MCA § 69-12-402 requires qualifying Montana motor carriers to comply with commission rules concerning insurance, bonds, security or permitted self-insurance sufficient to address qualifying final judgments arising from negligent motor-carrier operations.

For a commercial crash, identify:

• motor-carrier legal name
• USDOT number where applicable
• operating authority
• state certificate or permit
• vehicle classification
• cargo or passenger operation
• interstate or intrastate status
• required filings
• insurance certificates
• self-insurance status

Workers' compensation is a separate system

When the injured person is an employee injured in covered employment, Montana's Workers' Compensation Act may apply independently of the automobile liability claim.

Employer exclusivity

MCA § 39-71-411 generally makes workers' compensation the exclusive remedy against a covered insured employer for the employee's covered injury or death, subject to statutory exceptions.

Third-party claim preserved

MCA § 39-71-412 preserves an injured worker's cause of action against a negligent third party other than the employer or the employer's servants or employees.

Then address subrogation

MCA § 39-71-414 governs workers' compensation subrogation and cost sharing when the employee also pursues a third-party recovery.

Those reimbursement issues are addressed in more detail in the Montana MedPay & Subrogation guide.

Common work-use and commercial-vehicle mistakes

• Assuming company ownership automatically establishes employer liability.
• Assuming employee status automatically establishes scope of employment.
• Ignoring the employee's precise activity at the moment of the crash.
• Assuming unauthorized conduct is automatically outside employment.
• Assuming a personal vehicle cannot be used within the scope of employment.
• Stopping after finding the employee's personal insurance card.
• Stopping after finding the vehicle's commercial-auto policy.
• Failing to investigate employer hired/non-owned auto coverage.
• Assuming a listed driver is an insured for every coverage part.
• Assuming a family member of a corporate owner is a corporate-policy insured.
• Ignoring covered-auto symbols.
• Ignoring umbrella and excess policies.
• Adding a CGL limit without testing the auto exclusions.
• Assuming direct employer negligence exists merely because the employee was negligent.
• Failing to identify regulated motor-carrier status.
• Assuming private-auto minimum limits govern every commercial operation.
• Ignoring workers' compensation when an employee was injured.
• Ignoring workers' compensation subrogation in a third-party recovery.
