Frolic and Detour

Frolic and Detour

Introduction

An employee does not always perform a job in a perfectly straight line.

A delivery driver may stop for lunch. A salesperson may briefly visit a pharmacy. An employee running an errand for an employer may make a personal stop along the way.

These situations raise an important question in tort law:

When does an employee’s personal deviation from work remain within the scope of employment, and when does it become a personal departure for which the employer is no longer vicariously liable?

The traditional answer is expressed through the concepts of detour and frolic.

A detour is generally a relatively minor departure from an employee’s work-related activities. The employee may still be considered to be acting within the scope of employment.

A frolic is a more substantial departure from employment undertaken primarily for the employee’s own purposes. When an employee goes on a frolic of their own, the employer may generally escape vicarious liability for torts committed during that departure.

The distinction is part of the broader doctrine of respondeat superior, under which an employer may be held liable for an employee’s tort committed within the scope of employment.

The difficulty is that the boundary between a detour and a frolic is rarely a perfectly straight line.

---

What Is a Detour?

A detour is generally a minor deviation from an employee’s assigned work that does not take the employee outside the scope of employment.

The employee has departed from the precise route or task, but the employment relationship remains sufficiently connected to the conduct.

For example, imagine a delivery driver whose assigned route requires driving across town.

The driver stops for five minutes to buy a cup of coffee and then continues the delivery route.

That personal stop may be a detour rather than a frolic.

The employee has engaged in personal conduct, but the departure is relatively minor.

The employer may therefore remain vicariously liable for a tort occurring during the detour, depending on the applicable jurisdiction’s rules.

---

What Is a Frolic?

A frolic is generally a substantial departure from the employee’s work for the employee’s own purposes.

Imagine the same delivery driver.

Instead of briefly stopping for coffee, the driver decides to:

• abandon the delivery route;
• drive to a friend’s house;
• spend several hours there;
• use the employer’s vehicle for personal purposes.

The employee’s conduct has become substantially disconnected from the employer’s business.

If the employee causes an accident during that personal trip, the employer may argue that the employee was on a frolic of the employee’s own and was therefore outside the scope of employment.

Cornell LII describes this basic distinction as a minor departure for a detour versus a major personal departure for a frolic.

---

The Basic Formula

The traditional distinction can be summarized simply:

Work → minor deviation → detour → potentially still within scope

Work → substantial personal departure → frolic → potentially outside scope

The word “potentially” is important.

There is no single nationwide formula that determines every frolic-and-detour case.

States develop their own rules concerning respondeat superior and scope of employment.

Courts therefore examine the circumstances of the particular case.

---

Why Does the Distinction Matter?

The distinction matters because an employer’s vicarious liability generally depends on whether the employee was acting within the scope of employment.

If the employee is within the scope:

Employer may be vicariously liable.

If the employee is outside the scope:

Employer may not be vicariously liable under respondeat superior.

The employee, however, does not normally escape personal liability simply because the employer is not liable.

Thus, a finding that an employee was on a frolic may eliminate or limit the employer’s vicarious liability without eliminating the employee’s own liability.

---

The Classic Example

Consider a company that employs Alex as a delivery driver.

Alex is instructed to deliver a package to a customer.

Scenario One: Minor Stop

Alex stops at a gas station for five minutes, buys a drink, and continues toward the customer.

Alex causes a collision immediately after leaving the gas station.

This looks more like a detour.

Scenario Two: Major Personal Trip

Alex decides to drive thirty miles in the opposite direction to visit a friend.

Alex spends several hours there.

While returning to the delivery route, Alex causes a collision.

This looks much more like a frolic.

Scenario Three: Return to Work

Alex finishes the personal visit and resumes the delivery route.

The legal analysis may change once Alex returns to employment-related activity.

This is why courts often examine not only whether an employee departed from work, but also when the departure began, how substantial it was, and whether the employee had returned to work when the tort occurred.

---

The Employee’s Purpose

One important consideration is why the employee departed from the employer’s business.

A departure undertaken primarily to accomplish a personal objective is more likely to be characterized as a frolic.

A minor personal activity that occurs while the employee remains substantially engaged in the employer’s business is more likely to be characterized as a detour.

For example:

“I am still delivering the package, but I am stopping for lunch.”

is different from:

“I am abandoning the delivery for several hours to visit my friend.”

The first situation preserves a stronger connection to the employment.

The second creates a much stronger personal departure.

---

The Size of the Deviation

The physical distance or amount of time involved can matter.

A five-minute stop may be relatively minor.

A three-hour trip in the opposite direction is much more substantial.

But there is no universal mileage or time limit.

A ten-mile deviation might be significant in one context and relatively minor in another.

For example, a ten-mile deviation may be enormous for a local delivery driver whose entire route is two miles.

For a traveling salesperson who regularly drives hundreds of miles, the same distance may have little significance.

The context matters.

---

Time Matters

Courts may consider the duration of the employee’s departure.

A brief personal interruption is generally more compatible with a detour.

A lengthy personal excursion is more likely to suggest a frolic.

But time alone does not determine the answer.

The nature of the activity and its relationship to employment remain important.

---

Distance Matters

Distance can also provide evidence.

An employee who travels only slightly outside the assigned route may still be acting within the scope of employment.

An employee who travels far away for a completely personal purpose may be outside the scope.

Again, distance is evidence rather than an automatic rule.

---

The Nature of the Personal Activity

Not every personal activity has the same significance.

A court may distinguish between:

• buying lunch;
• using an ATM;
• stopping at a pharmacy;
• visiting a friend;
• attending a personal event;
• taking a lengthy personal trip;
• using an employer’s vehicle for a vacation.

The more substantial and independent the personal purpose becomes, the stronger the argument for a frolic.

---

The Employee’s Return to Employment

One of the most interesting questions arises when an employee leaves work temporarily and later returns.

Suppose a delivery driver:

1. leaves the delivery route;
2. drives to a friend’s house;
3. spends an hour there;
4. leaves the friend’s house;
5. returns to the delivery route;
6. causes an accident while completing the delivery.

The employee may have been on a frolic during the personal excursion.

But once the employee has returned to work, the employee may again be within the scope of employment.

The precise point at which the employee returns to the scope can therefore become legally important.

---

Frolic Does Not Necessarily Mean Permanent Abandonment

An employee can temporarily leave the scope of employment without permanently abandoning the employment relationship.

This is an important distinction.

Suppose an employee takes an unauthorized personal trip for two hours and then returns to the employer’s work.

The employee may have been outside the scope during those two hours.

But that does not necessarily mean the employee ceased being an employee.

The issue is the scope of the employee’s conduct at the time of the tort.

---

A Detour Can Become a Frolic

The distinction is not always fixed.

A small deviation can grow into a substantial personal departure.

Imagine a delivery driver who stops for lunch.

At first, the stop may be a detour.

But suppose the driver decides to visit a friend afterward, then goes shopping, then attends a personal event, and eventually spends most of the afternoon on personal activities.

What began as a small deviation may develop into a frolic.

The legal question therefore concerns the employee’s conduct as it evolved.

---

A Frolic Can End

The opposite can also occur.

An employee may begin a personal departure and later return to work.

For example:

Work → personal trip → return to work

The employee’s conduct during the personal trip may be outside the scope.

But once the employee resumes the employer’s business, the employee may again fall within the scope of employment.

This is sometimes described as the employee returning from the frolic.

---

Company Rules and Unauthorized Conduct

An employee’s violation of company rules does not automatically establish a frolic.

This distinction is crucial.

Suppose a delivery company instructs its drivers:

“Do not make personal stops while delivering packages.”

A driver nevertheless stops for five minutes to buy coffee.

The driver has violated an employer rule.

But the driver may still be acting within the scope of employment for purposes of respondeat superior.

The question is not simply:

“Did the employee disobey the employer?”

The more important question is:

“How far did the employee depart from the employer’s business?”

An employee can perform authorized work in an unauthorized manner.

That does not necessarily transform the conduct into a frolic.

---

Unauthorized Conduct vs. Personal Departure

This distinction can be expressed as follows:

Unauthorized Method

The employee is still performing the employer’s work but does so improperly.

Example:

A delivery driver speeds while making deliveries.

This may remain within the scope of employment.

Personal Mission

The employee abandons the employer’s work to pursue a substantially personal objective.

Example:

The driver abandons the delivery route for several hours to attend a personal event.

This is more likely to be a frolic.

The distinction is often more important than whether the employee violated a particular workplace rule.

---

The Employer’s Benefit

Another consideration is whether the employee’s conduct continues to serve the employer’s interests.

If the employee remains substantially engaged in business activities, the case for a detour becomes stronger.

If the employee is acting almost exclusively for personal benefit, the case for a frolic becomes stronger.

This is not necessarily an absolute test.

Cornell’s discussion of agency liability identifies control and economic benefit among considerations courts may use when distinguishing frolics from detours.

---

Employer Control

The amount of control the employer exercises may also matter.

If an employer tightly controls the employee’s route, schedule, and activities, a court may have a stronger basis for treating deviations as part of the employment context.

But employer control is only one consideration.

The employee’s actual conduct and purpose remain important.

---

The Nature of the Job

The same personal activity may have different significance depending on the nature of the employment.

Consider two employees.

Employee A

A local courier whose job requires driving a fixed delivery route.

Employee B

A traveling salesperson whose job requires spending entire days traveling between customers.

A deviation of twenty miles may be significant for Employee A but relatively ordinary for Employee B.

The scope-of-employment inquiry therefore depends heavily on the nature of the job itself.

---

Frolic and Detour vs. Going and Coming

Frolic and detour should be distinguished from the going-and-coming rule.

The going-and-coming rule generally concerns an employee’s ordinary travel between home and the workplace.

The frolic-and-detour doctrine generally concerns an employee who is already engaged in employment-related activity and then deviates from that activity.

For example:

Home → workplace

is typically a going-and-coming issue.

But:

Work → personal deviation → work

is more naturally analyzed as a frolic-and-detour issue.

Cornell LII notes that ordinary commuting is generally treated separately because the employment relationship is ordinarily considered suspended during the commute.

---

Frolic and Detour vs. Independent Contractor Status

These concepts also should not be confused with the employee/independent-contractor distinction.

Employee vs. Independent Contractor

This asks:

What kind of legal relationship exists between the worker and the business?

Frolic vs. Detour

This asks:

Assuming the worker is an employee, was the employee’s particular conduct within the scope of employment?

The questions occur at different stages of the analysis.

---

Intentional Torts and Frolics

Frolic-and-detour issues can arise in intentional-tort cases as well as negligence cases.

Suppose a security guard is assigned to protect a business.

During an argument with a customer, the guard uses excessive force.

The employer may potentially face vicarious liability depending on the circumstances.

But suppose the guard encounters a personal enemy at the workplace and attacks the person because of a purely private dispute.

The employer has a much stronger argument that the employee was acting outside the scope of employment.

The relationship between the employee’s conduct and the assigned work becomes critical.

---

Mixed Motives

Some cases are difficult because the employee has both personal and work-related motives.

Imagine a salesperson who is driving to meet a customer but stops to visit a friend.

The employee may be serving both:

• personal interests;
• employment interests.

Mixed motives do not necessarily produce a simple yes-or-no answer.

Courts may ask whether the employment-related purpose remained substantial enough to keep the conduct within the scope of employment.

---

The Scope of Employment Is the Larger Concept

Frolic and detour are best understood as tools for analyzing the broader concept of scope of employment.

Scope of employment concerns the range of conduct an employee can reasonably be regarded as performing as part of the job.

The exact formulation varies by jurisdiction.

Cornell LII describes scope of employment generally as the range of activities and conduct an employee is reasonably expected to perform as part of the job.

Frolic and detour help answer difficult questions near the boundary.

---

The Policy Behind the Doctrine

Why should an employer be responsible for a small personal deviation but not for a major personal journey?

The answer is largely about risk allocation.

Businesses necessarily expect employees to make ordinary human choices while performing their jobs.

Employees may:

• stop for food;
• take short breaks;
• make minor personal stops;
• deviate slightly from a route;
• engage in incidental personal activities.

Treating every tiny deviation as completely outside employment would make employer liability unpredictable and potentially unfair.

At the same time, an employer should not necessarily bear the cost of an employee’s entirely personal adventures.

The frolic-and-detour doctrine therefore attempts to draw a reasonable boundary.

---

Enterprise Risk

Respondeat superior is based partly on the idea that businesses should bear risks reasonably associated with their operations.

A delivery company creates risks because it sends drivers onto public roads.

If a driver makes a minor deviation while performing deliveries, the resulting accident may still be regarded as one of the risks associated with the enterprise.

But if the driver abandons the business for a substantial personal journey, the connection to the enterprise becomes much weaker.

The doctrine therefore asks where the enterprise’s risk reasonably ends.

---

Corrective Justice

The doctrine also raises questions of corrective justice.

An injured person may reasonably ask:

“Why should I bear the loss when an employee caused the accident while operating as part of a business?”

But the employer may respond:

“Why should my business pay for an employee’s entirely personal adventure?”

Frolic and detour attempts to balance these competing claims.

The legal system must decide when the employee’s conduct is sufficiently connected to the enterprise that the employer should bear the loss.

---

Economic Analysis

From an economic perspective, the doctrine can be understood as a method of identifying which risks belong to the enterprise.

If an employee’s conduct is closely connected to the business, assigning liability to the employer may:

• encourage safer business practices;
• promote insurance;
• distribute losses;
• internalize accident costs;
• encourage appropriate supervision.

If the employee is engaged in a substantial personal activity, imposing liability on the employer may produce weaker deterrence because the employer has less ability to control that personal conduct.

The distinction therefore reflects not merely historical terminology but a broader theory of risk allocation.

---

Hypothetical: The Coffee Stop

A bakery employs Sarah as a delivery driver.

Sarah is delivering cakes to customers.

While driving between two deliveries, she stops at a coffee shop for five minutes.

She leaves the coffee shop and negligently strikes a pedestrian.

Analysis

Sarah made a personal stop.

But the stop was brief.

She remained on the delivery route.

She immediately resumed work.

A court could reasonably characterize the conduct as a detour rather than a frolic.

The employer may therefore face vicarious liability, depending on the jurisdiction and specific facts.

---

Hypothetical: The Beach Trip

Now change the facts.

Sarah is delivering cakes.

Instead of proceeding to the next customer, she drives to the beach forty miles away.

She spends several hours there.

While driving along the beach road, she negligently injures another driver.

Analysis

Sarah has substantially abandoned the employer’s business.

The personal purpose is significant.

The geographic deviation is substantial.

The time away from work is substantial.

These facts strongly support characterization as a frolic.

The employer therefore has a stronger argument that Sarah was outside the scope of employment.

---

Hypothetical: The Frolic Ends

Suppose Sarah spends three hours at the beach and then returns to the delivery route.

While completing the next delivery, she causes an accident.

The result may be different.

The personal frolic may have ended when Sarah returned to the employer’s business.

The relevant question becomes:

Where was Sarah, and what was she doing when the tort occurred?

This illustrates why timing is so important.

---

Hypothetical: The Unauthorized Shortcut

A delivery driver is instructed to follow a particular route.

The driver decides to take a shortcut without permission.

The shortcut takes the driver through an unfamiliar neighborhood, where the driver negligently causes an accident.

The driver violated instructions.

But the driver was still trying to make the employer’s delivery.

This is more likely to be characterized as an unauthorized method of performing work rather than a personal frolic.

The employer may therefore remain within the scope of respondeat superior.

---

Hypothetical: Visiting a Friend

An employee is driving an employer’s vehicle to a customer.

The employee decides to stop at a friend’s house nearby.

The visit lasts twenty minutes.

Afterward, the employee continues to the customer.

Whether this is a detour or frolic depends on the circumstances.

Relevant considerations could include:

• how far the employee traveled;
• how long the stop lasted;
• whether the employee remained on the assigned route;
• whether the employee was expected to be traveling continuously;
• whether the employer’s business was significantly interrupted;
• whether the employee had effectively abandoned the assigned task.

This is precisely why frolic-and-detour cases are fact-sensitive.

---

A Practical Exam Framework

When analyzing a frolic-and-detour problem, use the following sequence.

Step 1: Identify the Employee

Confirm that the tortfeasor is an employee rather than an independent contractor.

Step 2: Identify the Underlying Tort

Determine what tort the employee allegedly committed.

Step 3: Identify the Assigned Work

What was the employee supposed to be doing?

Step 4: Identify the Deviation

What did the employee actually do?

Step 5: Measure the Deviation

Consider:

• time;
• distance;
• purpose;
• route;
• duration;
• degree of departure.

Step 6: Ask Who Benefited

Was the employee still substantially serving the employer?

Or was the employee acting primarily for personal benefit?

Step 7: Consider Employer Control

What did the employer control or expect?

Step 8: Ask Whether the Employee Returned to Work

If the employee temporarily left the scope, determine whether the employee had returned to employment when the tort occurred.

Step 9: Apply the Jurisdiction’s Rules

Remember that respondeat superior is governed by state-specific common law and potentially other applicable law.

Step 10: Separate Employer and Employee Liability

Even if the employer is not vicariously liable, the employee may remain personally liable.

Common Mistakes

Mistake 1: Thinking Every Personal Stop Is a Frolic

Employees are human beings.

Minor personal activities do not necessarily remove them from the scope of employment.

---

Mistake 2: Thinking Every Rule Violation Is a Frolic

An employee can violate company instructions while continuing to perform the employer’s business.

---

Mistake 3: Treating Time as the Only Factor

A long deviation is important, but courts may also consider purpose, distance, job duties, employer interests, and other circumstances.

---

Mistake 4: Forgetting the Employee’s Return

An employee may begin outside the scope and later return to work.

The exact timing of the tort matters.

---

Mistake 5: Confusing Frolic and Detour With Independent-Contractor Status

Employee classification and scope of employment are separate questions.

---

Mistake 6: Assuming the Employer Is Automatically Liable

Respondeat superior generally requires the employee to have been acting within the scope of employment.

A frolic is a substantial departure by an employee from employment for the employee’s own personal purposes.

---

What is a detour in tort law?

A detour is generally a minor deviation from an employee’s assigned work that remains sufficiently connected to the employment.

---

Is an employer liable for an employee’s detour?

Potentially, yes.

A detour may remain within the scope of employment, allowing respondeat superior to apply.

---

Is an employer liable for an employee’s frolic?

Generally, an employer has a stronger defense when the employee is engaged in a substantial personal frolic outside the scope of employment.

Is there a fixed distance that makes something a frolic?

No.

There is generally no universal mileage rule.

Courts examine the overall circumstances.

---

Is commuting to work a frolic?

Conclusion

The doctrine of frolic and detour illustrates how tort law handles the messy reality of human behavior at work.

Employees do not always travel directly from one assigned task to another. They stop for food, make personal calls, take shortcuts, visit friends, run errands, and occasionally make much more substantial departures from their jobs.

The law therefore needs a way to distinguish an ordinary deviation from a genuine abandonment of employment.

A detour generally represents a minor departure that remains sufficiently connected to the employee’s work.

A frolic represents a substantial personal departure in which the employee has moved outside the scope of employment.

The distinction is not merely about distance or time. It concerns the relationship between the employee’s conduct and the employer’s enterprise.

The deeper question is:

Is this still reasonably one of the risks created by the employee’s work, or has the employee embarked on a substantially personal activity for which the employer should no longer be responsible?

That question places frolic and detour at the heart of scope of employment, respondeat superior, vicarious liability, and enterprise responsibility.
