UCR — Unified Carrier Registration (Annual, due January 1)

Every interstate carrier must register in the UCR system and pay a fee based on fleet size. For 1–2 vehicles the fee is $46 per year. Registration opens October 1 for the following year. Operating without a valid UCR puts your authority in jeopardy and can trigger roadside violations under 49 CFR 390.

IFTA — International Fuel Tax Agreement (Quarterly filings)

If your qualified motor vehicle travels in two or more IFTA jurisdictions, you file quarterly returns (Q1 due April 30, Q2 due July 31, Q3 due October 31, Q4 due January 31). Missed filings trigger interest, penalties, and can result in license revocation. Keep fuel receipts and mileage logs for every quarter.

IRP — International Registration Plan (Annual, apportioned plates)

Your apportioned plate registration renews annually through your base state. The renewal window opens roughly 60 days before your plate’s expiration month. An expired IRP plate is a federal out-of-service criterion at any weigh station. File early — IRP offices in many states have multi-week processing backlogs.

MCS-150 Biennial Update — Every 24 months by USDOT issue month

FMCSA requires every registered motor carrier to update its MCS-150 (Motor Carrier Identification Report) every two years. Your deadline is determined by the month your USDOT number was originally issued. Skip it and FMCSA marks your USDOT inactive — which shows up on carrier lookups and can trigger broker rejections within 24 hours.

Drug & Alcohol Consortium (Ongoing, random testing pool)

Every CDL driver subject to FMCSA regulations must be enrolled in a DOT-compliant drug and alcohol testing consortium at all times. Consortium fees are typically annual, but the compliance obligation is continuous. A driver selected for random testing who is not enrolled faces immediate disqualification.

Annual DOT Vehicle Inspection — By a certified mechanic

49 CFR 396.17 requires every commercial motor vehicle to pass an annual inspection performed by a qualified inspector. The inspection sticker must be current. At any roadside check, an expired annual inspection is an out-of-service violation. Schedule inspections 30 days early to avoid gaps if the vehicle needs repairs before it can pass.

Driver MVR Review — Annual per FMCSA

Carriers must review each driver’s motor vehicle record (MVR) at least once every 12 months under 49 CFR 391.25. The review must be documented and kept in the driver qualification file. A missed annual MVR review is a recordable violation during a DOT audit and can affect your safety rating.

Medical Certificate — Typically every 2 years (more often for some conditions)

CDL drivers must hold a valid FMCSA medical certificate issued by a National Registry medical examiner. The standard maximum is 24 months, but conditions like hypertension or sleep apnea may require 3-, 6-, or 12-month certificates. Driving on an expired medical certificate is an automatic CDL disqualification. Hours-of-service rules and medical certification are tightly linked — stay current on both.

Insurance Renewal — Annual policy

Your primary liability, cargo, and any required bond (BMC-84) renew annually. FMCSA monitors insurance filings in real time — if your insurer cancels or lets coverage lapse without filing a replacement, your operating authority can be revoked automatically within 30 days of the cancellation notice. Confirm renewal dates with your broker 60 days in advance.
