I’ve lost count of how many times I’ve heard some version of this line: You’re not working, you’re just driving. It sounds reasonable. It’s also often wrong.

If you manage people who travel for work – techs in vans, consultants on planes, nurses between facilities, sales reps on the road – your biggest hidden cost may not be airfare or mileage. It’s the time you’re quietly treating as free.

This guide breaks down when U.S. employers must pay for commutes, layovers, and after-hours travel under the Fair Labor Standards Act (FLSA) and the Portal-to-Portal Act. Along the way, we’ll look at common travel time pay compliance mistakes, and how to avoid turning routine trips into expensive wage-and-hour problems.

1. Is the commute really “just a commute” – or did you accidentally start the workday?

Let’s start with the part most people think they understand.

Under the FLSA and the Portal-to-Portal Act, ordinary home-to-work and work-to-home commuting is not paid time. That’s true even if:

  • The drive is long or frustrating.
  • The employee uses their own car or a company vehicle.
  • The worksite changes day to day but stays within a normal commuting area.

Regulations like 29 CFR § 785.35 are blunt: routine commuting is personal time.

But here’s where employers quietly cross the line and turn a commute into paid work time:

  • Central reporting locations. If you require employees to report to a yard, warehouse, or office first to pick up tools, vehicles, instructions, or coworkers, paid time starts there. The drive from that central point to the jobsite is work time, not a commute (see Employment Law Handbook).
  • Work during the drive. If an employee is answering calls, taking instructions, or doing anything more than minimal tasks while driving, that time becomes compensable. The same goes if they’re a passenger working on a laptop or phone instead of treating it as personal time.
  • Emergency call-backs. When someone is called back in after hours and has to travel an unusually long distance, that travel may be compensable under 29 CFR § 785.36. The more “out of the ordinary” the trip, the more likely it’s paid.

So the real question isn’t Is this a commute? It’s: Has the employee started doing things primarily for your benefit? Once the answer is yes, the clock usually starts, and that time becomes part of your employee travel time costs.

2. Are you treating “all in a day’s work” travel as free?

Here’s a simple rule that trips up a lot of businesses: once the workday starts, most travel is paid.

The Department of Labor calls this the all in the day’s work rule (29 CFR § 785.38). In practice, that means:

  • Travel between worksites is compensable. If a technician drives from Site A to Site B, or a nurse goes from Facility 1 to Facility 2, that travel is work time. Under most business travel time labor laws, this is not optional.
  • Travel from a central meeting point is compensable. If employees meet at a yard to load a truck and then ride together to the jobsite, the ride from the yard to the site is paid.
  • End-of-day travel home is not. Once they leave the last worksite and head home, that’s back to non-compensable commute time.

Where companies get into trouble is inconsistency. They pay for some intra-day travel but not all, or they let supervisors “decide” on the fly. That’s how wage-and-hour claims start.

If you want to stay out of trouble with travel time pay rules, you need three things:

  • A written policy that clearly says: travel between worksites during the day is paid.
  • A way to track it – timekeeping apps, mileage logs, or simple start/stop entries.
  • Training for managers so they don’t tell employees to clock out while driving between jobs.

Ask yourself: If an auditor pulled three random employees and asked about travel between sites, would they all give the same answer? If not, your travel time compensation policy needs work.

3. One-day trips out of town: are you paying for the right hours?

Now it gets more interesting. Imagine this scenario:

Your employee normally works 9–5 in City A. One day, you send them to City B, two hours away, for a special assignment. They leave home at 6 a.m., drive two hours, work 9–3, then drive back and get home at 5 p.m.

What’s paid?

Under the FLSA rules for same-day out-of-town travel (29 CFR § 785.37):

  • The travel is primarily for your benefit and outside their normal commute, so it’s generally compensable.
  • You can usually subtract their normal commute time from the total travel hours.

In practice, many employers handle this type of employee travel time pay like this:

  • Pay from the time the employee leaves home until they return, minus their usual commute (say 30–45 minutes each way).
  • Do not pay for normal meal breaks where the employee is completely off duty.

What you shouldn’t do is treat the whole thing as unpaid because they’re just driving. The trip exists only because of your business needs. That’s the key test in most commute vs work travel pay questions.

Ask yourself:

  • Is this travel outside the employee’s normal daily pattern?
  • Would they be making this trip if not for my business?

If the answer to both is yes, assume the time is compensable (minus the normal commute), then confirm with counsel or state guidance if you’re in a stricter jurisdiction. Some state laws on employee travel pay go beyond the federal FLSA travel time guidelines.

4. Overnight trips, flights, and layovers: when does the clock actually run?

Overnight travel is where most people’s intuition fails. The law doesn’t care whether it’s a weekday or weekend. It cares about the employee’s normal working hours.

Here’s the core rule from 29 CFR § 785.39 and related guidance:

  • Travel during normal working hours is compensable – even on Saturdays, Sundays, or holidays.
  • Travel outside normal working hours is usually not compensable if the employee is a passenger and free to use the time for themselves.
  • Any actual work performed while traveling is compensable, regardless of the time of day.

Let’s make it concrete. Suppose an employee normally works 8 a.m.–4 p.m., Monday–Friday.

  • If they fly on Sunday from 1–5 p.m., 1–4 p.m. is paid, 4–5 p.m. is generally not.
  • If they fly on Friday from 6–10 p.m., and they’re just watching movies, that’s usually not paid.
  • If they spend that same flight writing reports or answering work emails, those hours are paid.

What about layovers and airport time?

  • Time spent waiting at the airport during normal working hours is usually compensable.
  • Long layovers outside normal hours are more nuanced. If the employee is completely relieved from duty and free to use the time for personal purposes, it may be non-compensable. But if they’re expected to stay available, monitor email, or handle issues, that leans toward paid time.

One more twist: if the employee is driving instead of flying, and you require that choice, the rules are stricter. Driving time that would otherwise be outside normal hours may still be compensable because they can’t use that time freely. That’s where after hours travel time pay often comes into play.

The safest mindset: assume travel during normal hours is paid, and treat any work performed outside those hours as paid too. Then build your travel schedules and layover expectations around that reality.

5. Company vehicles, carpools, and “just swing by and pick them up”

Company vehicles create a false sense of security. Many employers assume that if they provide the vehicle, they control the rules. The law disagrees.

Under the Portal-to-Portal Act, commute time in an employer-provided vehicle can be non-compensable if:

  • The travel is within a normal commuting area.
  • Use of the vehicle is by mutual agreement.
  • The employee is not performing additional work while traveling.

But the moment you add extra duties, things change:

  • Picking up coworkers. If you require an employee to pick up others on the way, that can turn the trip into compensable work time because it’s now for your benefit.
  • Loading/unloading equipment. If they have to load tools at home or at a yard before driving, the workday may start when that loading begins, not when they arrive at the jobsite.
  • Taking calls or instructions. If the drive becomes a rolling meeting, it’s hard to argue it’s personal commute time.

Ask yourself a blunt question: If this employee stopped doing this travel, would my business suffer? If the answer is yes, you should at least analyze whether that time is actually work time under the FLSA and your state’s rules on employer obligations for travel time.

6. Overtime, multiple rates, and the real cost of travel time

Even when employers get the is it paid? question right, they often miscalculate how to pay it.

Key points from sources like OnPay and Hourly:

  • All compensable travel hours count toward overtime. If travel pushes a non-exempt employee over 40 hours in a workweek, those extra hours must be paid at time-and-a-half.
  • You can use a different rate for travel time (as long as it’s at least minimum wage and agreed in advance), but overtime must be based on a weighted average of all rates worked that week.
  • Exempt employees generally don’t have a legal right to extra travel pay. Their salary covers all hours worked. But many employers still offer travel stipends or comp time as a retention tool.

Here’s where the hidden cost of employee travel time shows up: you might think you’re saving money by not paying for certain travel. In reality, you may be:

  • Underpaying overtime for weeks with heavy travel.
  • Creating a pattern of violations that can trigger back pay, penalties, and attorney’s fees.
  • Breeding resentment among employees who feel their time is being taken for granted.

Run this thought experiment: if you had to retroactively pay two years of travel time plus overtime for your field staff, what would that number look like? If the answer makes you uncomfortable, it’s time to tighten how you’re calculating employee travel time costs.

7. Building a practical, defensible travel-time policy

Most companies don’t get in trouble because they’re malicious. They get in trouble because they’re vague.

A solid travel-time policy does a few things very clearly:

  1. Defines what is and isn’t a commute.
    Spell out that normal home-to-work travel is unpaid, but travel between worksites, from central reporting locations, and for special assignments is paid. Make the commute vs work travel pay distinction obvious.
  2. Explains same-day and overnight travel rules.
    Use examples: flights on weekends, long drives, layovers, and when employees should be on the clock. Tie these examples back to FLSA travel time guidelines so managers understand the why, not just the what.
  3. Addresses company vehicles and carpools.
    Clarify when the clock starts if employees pick up vehicles, tools, or coworkers, and how that affects paid commute time rules.
  4. Sets pay rates and overtime handling.
    If you use a lower travel rate, document it, communicate it, and make sure your payroll system handles weighted-average overtime correctly.
  5. Requires accurate time tracking.
    Give employees a simple way to record travel time – apps, spreadsheets, or clear start/stop rules – and train them to use it. Without records, even the best travel time compensation policy is just words on paper.
  6. Accounts for state law.
    Some states are stricter than federal law. Always check your state’s Department of Labor guidance, especially if you operate in multiple states where state laws on employee travel pay may differ.

Then, test your policy against reality. Ask a few traveling employees to walk you through a typical week. Where do they start the clock? When do they stop? If their answers don’t match your policy, fix the practice or fix the policy – but don’t ignore the gap.

8. The real question: whose time is it?

At the end of the day, travel-time disputes come down to one simple question: whose time is this?

  • If the travel is something the employee would do anyway, for their own life, it’s probably a commute.
  • If the travel exists only because you need them somewhere, at a certain time, doing something for your business, it’s probably work.

The law gives you structure – FLSA, the Portal-to-Portal Act, and regulations like 29 CFR §§ 785.35–39. But the mindset matters just as much. When you treat employee time as valuable, you’re far less likely to cut corners that turn into lawsuits over layover time compensation for employees or unpaid travel.

So look at your current practices. Where are you assuming time is free? Where are you relying on we’ve always done it this way instead of actual rules? That’s where your hidden travel-time costs – and risks – are hiding.

Once you see them, you can decide: pay a little more now, or risk paying a lot more later.
