The Mixed-Fleet Overtime Trap

By Curtis Cox · June 3, 2026 · 4 min read

If you run a FedEx Ground operation entirely on step vans above 10,000 pounds GVWR, you can stop reading — your daily pay structure is clean and this trap never touches you. This article is for everyone else: the contractor with a yard full of step vans and a Sprinter or two for cleanup, peak, or small-route days. That mix is where the most expensive wage-and-hour mistake in this business hides.

This is the companion piece to the 10,000 GVWR rule. That article explains the Motor Carrier Exemption and why bigger trucks let you pay drivers a daily rate instead of hourly. Read it first if the terms MCE, GVWR, or daily rate are not already familiar — this piece assumes them.

A note: this article is informational and not legal advice. Wage-and-hour law varies by state and changes over time. Have your specific compensation structure reviewed by a qualified employment attorney before adoption.

The exception, in plain English

The SAFE Transportation Act of 2005 (refined by the Technical Corrections Act of 2008) created what is sometimes called the “small-vehicle exception” or the “corrected coverage” provision. The exact wording matters, so here it is in plain English:

If a driver who is ordinarily classified as Motor Carrier Exempt — because they typically operate vehicles above 10,000 lbs GVWR — operates a vehicle at or below 10,000 lbs GVWR at any point during a workweek, even for half of one shift, that driver is entitled to federal overtime for the entire workweek.

Read that again. It is not a per-shift rule. It is not a per-day rule. It is a per-workweek rule. One trip in a Sprinter on a Tuesday triggers federal overtime for that driver from Monday through Sunday.

Why mixed fleets are dangerous

The trap is built for the contractor who maintains a mixed fleet. The typical pattern is:

• The contractor runs step vans (>10K GVWR) as the primary fleet.
• The contractor keeps a Sprinter or two for cleanup runs, peak coverage, AVP-like duties, or small-route days.
• Drivers occasionally swap between vehicles based on operational need.

The contractor thinks: my drivers are mostly in the step vans, so they’re MCE-exempt, so I pay them daily.

The reality: every driver who touched a sub-10K vehicle in a given workweek triggered federal overtime for that whole week. The contractor has been underpaying overtime on those workweeks without realizing it. The exposure compounds, quietly, week after week. If a driver later files a wage-and-hour claim, the back-pay calculation can reach back across every one of those workweeks at once.

This is the single biggest hidden liability in mixed fleets, and it is genuinely under-recognized in the contractor community.

How to manage it

There are a few practical strategies:

1. Don’t run sub-10K vehicles at all. The cleanest solution. If your fleet is 100 percent above 10K GVWR step vans, the exception never triggers and your daily pay structure is bulletproof.

2. Dedicate specific drivers to sub-10K vehicles. If you must run smaller vehicles, assign them only to drivers who are paid hourly to begin with. Their pay structure is already set up for overtime. They never cross-train into the step vans.

3. Track weekly vehicle assignments carefully. If a driver does cross between vehicle classes, document the workweek and recalculate pay accordingly. This is doable but tedious.

4. Pay all drivers hourly. A clean solution if you have a meaningful mix of vehicles. You lose the efficiency rewards of daily pay, but you simplify the compliance picture significantly.

5. Avoid AVP as a strategy. AVP vehicles are almost always sub-10K (personal SUVs, minivans, and the like). Running AVP regularly means continuously triggering overtime on AVP drivers — adding another layer of cost to an already-bad economic structure.

My own preference, and what we do at our operation, is strategy #1: own only step vans above 10K GVWR, and accept the operational discipline of routing only what those vehicles can serve. The simplicity dividend across operations, payroll, and compliance is real.

The 90-day self-audit

If you have not specifically reviewed your fleet against the 10,000 lbs GVWR line and your driver pay against the small-vehicle exception, here is the work:

1. Pull a list of every vehicle in your fleet, with its GVWR. The GVWR is on the federal certification sticker on the driver’s-side door jamb of each vehicle.

2. Sort vehicles into “above 10K” and “at-or-below 10K.”

3. For each driver in the last 90 days, identify which workweeks they touched a sub-10K vehicle.

4. Verify that those workweeks were paid as overtime-eligible workweeks — hourly pay with proper overtime calculation, or daily rate with reverse-engineered overtime documented.

5. If you find workweeks where this wasn’t done correctly, talk to an employment attorney about back-pay exposure.

6. Build a vehicle-assignment policy that prevents accidental triggering of the small-vehicle exception going forward.

This is unglamorous work but it is high-leverage. The exposure you find today is much cheaper to fix than the exposure that surfaces in a FedEx payroll audit or a wage-and-hour claim later.

The single sentence to take with you

If you remember one sentence from this article, make it this one:

One trip in a sub-10,000 lbs GVWR vehicle makes a normally-exempt driver overtime-eligible for the entire workweek — so a mixed fleet quietly converts your clean daily-pay drivers into back-pay liability, one Sprinter run at a time.

The cheapest fix is structural: keep your drivers and your sub-10K vehicles in separate lanes, or don’t run sub-10K vehicles at all.
