Small Fleet DOT Compliance Checklist: What's Due and When

Small fleets answer to the same FMCSA rules as large carriers, usually without a safety department. This checklist from Diversified Safety & Compliance organizes the recurring work by when it comes due, so nothing catches you by surprise. It's a planning aid, not legal advice; the cited rules have the full requirements. Just starting out? Begin with the new trucking company checklist.

Every time you hire a driver

• A verified negative DOT pre-employment drug test before first duty (49 CFR 382.301)
• A full Clearinghouse query before first duty (49 CFR 382.701)
• A complete driver qualification file: application, MVRs from every state licensed in the past 3 years, road test or equivalent, and a current medical certificate (49 CFR 391.51)
• Safety performance history from the driver's previous DOT employers (49 CFR 391.23)
• The driver added to your random testing pool

The calendar

• January: check DOT's random testing rates for the new year; FMCSA's 2026 minimum is 50% for drugs and 10% for alcohol (49 CFR 382.305)
• January 31: IFTA fourth-quarter return
• April 30: IFTA first-quarter return
• July 31: IFTA second-quarter return
• August 31: Form 2290 for vehicles in use in July
• October 31: IFTA third-quarter return
• December 31: UCR for the coming year, and your IFTA license renewal
• Your IRP renewal month: apportioned registration

Every 12 months, for every driver

• An updated MVR and a documented review (49 CFR 391.25)
• A limited Clearinghouse query (49 CFR 382.701)
• Random testing throughout the year at the FMCSA minimum rates

Every 24 months: your MCS-150

Your MCS-150 update is due every two years, by the end of the month set by your USDOT number (49 CFR 390.19). The last digit sets the month: 1 is January, 2 is February, and so on through 9 for September, with 0 for October. The next-to-last digit sets the year: odd digits file in odd-numbered years, even digits in even-numbered years. The update now goes through FMCSA's Motus system.

On their own schedules

• Medical certificates, which expire on the date the examiner sets. Book the DOT physical before the card runs out.
• Supervisor training: anyone who makes reasonable suspicion calls needs 60 minutes on drugs and 60 minutes on alcohol before making one (49 CFR 382.603). See reasonable suspicion training.

When something happens

• After a crash that meets the DOT criteria: alcohol testing within 8 hours and drug testing within 32 hours (49 CFR 382.303). See the post-accident testing checklist.
• After a violation: removal from duty, the return-to-duty process with a substance abuse professional (SAP), then at least 6 directly observed follow-up tests in the first 12 months (49 CFR 40.307(d)).

What happens if you miss a deadline

• MCS-150: FMCSA deactivates your USDOT number, and civil penalties can apply.
• IFTA: in Nebraska, a late return draws a penalty of $50 or 10% of the net tax due, whichever is greater, plus interest.
• Medical certificate: the driver isn't qualified to drive until a new one is issued.
• Annual MVR review or Clearinghouse query: a gap an auditor will find, and a driver you can't show is qualified.
