DOT Compliance Calendar: Recurring Deadlines Every Fleet Manager Must Hit (2026)
FMCSA enforcement scaled hard in 2024: 94% of safety investigations found at least one violation, and 55% included acute or critical findings serious enough to affect a carrier's safety rating. The reason most carriers fail audits is not a willful violation — it is a missed recurring deadline. A driver's medical card expires. The Clearinghouse annual query is overdue. An MVR pull was skipped.
This is the full 365-day calendar of recurring FMCSA / DOT obligations, with the retention rule and alert lead time for each.

The driver-side deadlines
Per-driver recurring obligations
- ✓
Medical Examiner's Certificate (Med Card) — up to 2 years; many drivers shorter based on conditions
- ✓
CDL renewal — varies by state (typically 4–8 years; many states require commercial endorsement renewals more frequently)
- ✓
Motor Vehicle Record (MVR) — annual pull required by 49 CFR 391.25
- ✓
Annual driver review (391.25) — including the MVR plus inquiry to former employers
- ✓
Drug & alcohol pre-employment test (391.103) — before first dispatch
- ✓
Drug & alcohol random selection program — quarterly pulls, 50% drug / 10% alcohol
- ✓
FMCSA Clearinghouse — annual full query per driver, plus pre-employment
- ✓
Driver Investigation History File (DIHF) — investigation within 30 days of hire
- ✓
Hours of Service (HOS) records — ELD data retention 6 months
⚠️An expired medical card is the single most common driver-side audit finding. Drivers do not always tell you the new cert was downgraded or shortened — set the alert to fire 90 days before the recorded expiry, not 30.
The vehicle-side deadlines
Per-vehicle recurring obligations
- ✓
Annual vehicle inspection (49 CFR 396.17) — every 12 months, evidence retained 14 months
- ✓
Daily Vehicle Inspection Report (DVIR) — pre-trip and post-trip, retain 3 months
- ✓
IFTA quarterly fuel-tax report — Q1 due April 30, Q2 July 31, Q3 October 31, Q4 January 31
- ✓
IRP apportioned registration — annual renewal per state cycle
- ✓
UCR (Unified Carrier Registration) — annual by December 31
- ✓
Form 2290 Heavy Vehicle Use Tax — annual by August 31 for current tax year
- ✓
Hazmat permits and renewals (HM-126F / HM-181) — per state cycle
💡 Pro Tip
IFTA quarterly filings sneak up because they are tax-cycle, not anniversary-cycle. Calendar all four IFTA dates as recurring fixed-date events, not "every 90 days."
The carrier-side deadlines
Carrier-level recurring obligations
- ✓
MCS-150 biennial update (and any time information changes)
- ✓
Drug & Alcohol Clearinghouse annual queries — by anniversary date
- ✓
New entrant safety audit (within first 12 months for new applicants)
- ✓
CSA SMS review — monthly internal review of each BASIC
- ✓
CSA SMS dispute window for new violations — 6 months from each event
- ✓
Insurance filing currency — MCS-90 and BMC-91/91X kept on file
- ✓
Operating authority renewal (where applicable)
Retention rules — the part auditors actually verify
It is not enough to do the inspection or pull the MVR. The record must be retrievable for the retention period. The most common rules:
Retention periods (memorise these)
- ✓
Driver qualification file — 3 years after termination
- ✓
Drug & alcohol testing records — 5 years (positive tests) / 1 year (negative)
- ✓
Hours of Service logs — 6 months from date of record
- ✓
DVIRs — 3 months from date of record
- ✓
Vehicle maintenance and inspection records — 14 months / 1 year after vehicle leaves fleet
- ✓
Accident register — 3 years
- ✓
Clearinghouse query records — 3 years
ℹ️During an audit you will be asked for specific records on demand. If the record exists but you cannot find it in under five minutes, the auditor will note it as a record-keeping failure. The retrievability test matters as much as the retention itself.
The audit day playbook
When the notice arrives, you typically have 7–10 business days. The six FMCSA focus areas (the BASICs) are predictable; the audit drills into the ones with weak performance. Pre-build a "war kit" for each:
Pre-built war kit per BASIC
- ✓
Unsafe Driving — sample driver files, training records, last 12 months of moving violations
- ✓
Hours of Service Compliance — ELD audit reports, exception logs, HOS violations
- ✓
Driver Fitness — medical cards, CDL endorsements, MVRs, road tests
- ✓
Controlled Substances/Alcohol — testing rosters, Clearinghouse evidence, random selection program
- ✓
Vehicle Maintenance — annual inspections, DVIRs, repair orders
- ✓
Hazmat Compliance (if applicable) — permits, training, shipping papers
Where this typically breaks
1. Medical card expiry
Driver doesn't volunteer the new cert is shortened. Solution: ask for the certificate copy itself, set the alert from the actual expiry date on the document, not the calendar default.
2. Annual Clearinghouse query
Easy to forget because it is annual, not quarterly. Solution: calendar it against each driver's anniversary, not a fleet-wide single date.
3. New driver investigation history
Must be completed within 30 days of hire. Many carriers do the pre-employment piece then stall on the former-employer inquiries. Solution: treat 30-day post-hire as a hard deadline with its own alert.
How ExpiryEdge fits in a DOT compliance program
Every item on this calendar has a date, an owner, an interval, and an evidence requirement. ExpiryEdge tracks them per driver and per vehicle, with alerts at 90 / 60 / 30 days where the lead time matters and 30 / 7 days where the cycle is short. Audit-day exports give you a defensible record per BASIC, retrievable in under five minutes.
