Static educational checklist — not a calculator. No punch grids, no DOT-jurisdiction engines, no live Motor Carrier Act overtime math. Spot common FLSA § 13(b)(1) / 29 U.S.C. § 213(b)(1) Motor Carrier Act overtime-exemption red flags: when employees whose activities affect the safety of operation of motor vehicles in interstate commerce (drivers, driver’s helpers, loaders, and mechanics under FMCSA / Secretary of Transportation jurisdiction) may be exempt from FLSA after-40 overtime, and when payroll wrongly parks local clerks, small-vehicle weeks, intrastate-only routes, or petroleum-bulk yard staff under a blanket “CDL = no overtime” rule. Distinct from the petroleum § 7(b)(3) Part 794, CBA § 7(b)(1)/(2), hospital § 7(j) 8/80, fire/police § 7(k), and premium-credit cheat-sheet pages.
Baseline — what § 13(b)(1) requires (and does not)
Under 29 U.S.C. § 213(b)(1), the FLSA overtime provisions of § 7 do not apply to any employee with respect to whom the Secretary of Transportation has power to establish qualifications and maximum hours of service pursuant to the Motor Carrier Act (today administered through FMCSA / DOT authority). DOL’s interpretive rules in 29 CFR Part 782 and WHD Fact Sheet #19 focus the exemption on employees who (1) are employed by a carrier subject to the Secretary’s jurisdiction and (2) engage in activities that directly affect the safety of operation of motor vehicles in transportation on the public highways in interstate or foreign commerce — classically drivers, driver’s helpers, loaders, and mechanics. The exemption is about DOT power and safety-affecting duties, not about every worker with a CDL, every warehouse associate near a dock, or every week on every vehicle. Congress’s SAFETEA-LU / Technical Corrections Act small-vehicle amendments further limit the overtime exemption for employees whose work, in whole or in part, is on vehicles weighing 10,000 pounds or less GVWR (with covered “covered employee” / overtime-restoration weeks). This page does not decide DOT jurisdiction or compute MCA overtime — it only flags compliance red flags.
Checklist — motor carrier § 13(b)(1) red flags
Non–DOT-jurisdiction / non-carrier force-fits. Flag employers that are not motor carriers (or private carriers) subject to the Secretary of Transportation’s power to set qualifications and maximum hours, yet park staff under § 13(b)(1) because “we have trucks,” “they have CDLs,” or “FMCSA forms are on file somewhere.” No Secretary power → no § 13(b)(1) overtime exemption, even if the job looks transportation-adjacent.
Non-interstate / purely local continuity myths. Flag routes that never leave the state and lack a practical continuity of movement in interstate or foreign commerce (through bills, out-of-state origin/destination legs, or bona fide interstate character), yet are still labeled “interstate motor carrier exempt.” Intrastate-only weeks without interstate nexus generally return toward ordinary § 7(a) overtime analysis for those employees/weeks.
Non–safety-affecting duty myths. Flag clerks, sales reps, dispatchers, warehouse pickers, fuelers, and yard leads who do not drive, help the driver, load (as a safety-affecting loader), or repair/maintain vehicles as mechanics — then claimed exempt solely because they work “for a trucking company.” Part 782 turns on safety-affecting activities, not job titles or proximity to a dock.
Drivers / helpers / loaders / mechanics mislabels. Flag inflated “loader” titles for employees who only stage cartons away from the vehicle, “mechanic” labels for parts-runners or wash-bay staff, and “helper” labels for riders who never assist in the safety of operation. Also flag mixed-duty employees whose safety-affecting work is de minimis or sporadic, yet treated as full-time exempt every week without a duties analysis.
Small-vehicle ≤10,001 lb / SAFETEA-LU gaps. Flag fleets that ignore the small-vehicle overtime-restoration rules for employees whose work is on motor vehicles weighing 10,000 pounds or less GVWR. Weeks spent (in whole or in part) on small vehicles can restore FLSA overtime even when the same employee is MCA-exempt on heavier equipment in other weeks. A blanket “CDL forever, never OT” policy fails the weight/week gate.
Petroleum § 7(b)(3) / CBA § 7(b) / hospital 8/80 / § 7(k) collapses. Flag manuals that treat motor-carrier § 13(b)(1) as interchangeable with petroleum Part 794 12/56 wholesale-bulk schedules, CBA 1,040 / 2,080 guaranty plans, hospital § 7(j) 8-and-80 agreements, or public-agency fire/LE § 7(k) work periods. § 13(b)(1) is a DOT-jurisdiction overtime exemption; § 7(b)/(j)/(k) are separate partial overtime systems with different gates and different premium outcomes.
State-floor / trucking-OT overlays. Flag multi-state employers that assume a federal § 13(b)(1) exemption also erases a stricter state overtime floor for the same hours — for example New Jersey’s trucking overtime at not less than 1½× the state minimum wage after 40 for certain MCA-covered drivers/helpers/loaders/mechanics, or California Wage Order daily/weekly overtime that still applies when the federal MCA exemption is claimed. Federal exemption ≠ automatic state silence.
Stub / DOT-proof / record gaps. Flag wage statements that never show which weeks were claimed under § 13(b)(1), missing vehicle GVWR / small-vehicle week logs, no documentation of interstate character or safety-affecting duties, CDL photocopies standing in for a Part 782 analysis, and “motor carrier exempt” lines with no audit trail when state trucking OT or ordinary after-40 still applies. Without DOT-jurisdiction proof and clear stubs, every long week becomes an after-40 fight.
