DOT compliance checklist: every file, every deadline
Most DOT findings are not rules nobody knew about. They are a record that expired, a renewal nobody owned, or a document that sat in the office instead of the cab.
Written by Rigo Diaz
The checklist in numbers
A DOT compliance checklist covers four files and the cab: company registration and insurance, each driver's qualification and hours records, the drug and alcohol program, each vehicle's maintenance records, and the documents every driver carries. Most items renew on a clock, so the checklist is really a calendar with an owner for every date.
A DOT compliance checklist is only useful if it says who checks what, and when. A binder that was complete the day you built it drifts out of date one expiration at a time.
I spent more than six years in risk management before I founded Simplex, and I have led it for more than 25 years since. From a risk point of view, every lapsed item on this list is a finding waiting for an auditor, a roadside officer, or an underwriter to read it. This checklist follows the way the records are kept, with the clock that keeps each one current.

Key takeaways
Check first which rules apply
Most safety rules start at 10,001 pounds in interstate commerce. Drug and alcohol testing applies to drivers who need a CDL.
Keep four files, not one binder
Company, driver, drug and alcohol, and vehicle records each have their own retention period, from three months to five years.
Many items run on a 12-month clock
The annual vehicle inspection, the driving record inquiry and review, and the Clearinghouse query are all due at least once a year.
The cab has its own checklist
License, cab card, IFTA license copy, ELD packet, and inspection proof. CDL drivers licensed outside Alaska no longer rely on a paper medical card.
Registrations renew on fixed dates
The MCS-150 every 24 months, UCR before January 1, IFTA every quarter, and Form 2290 for each July-to-June period.

Who needs a DOT compliance checklist?
Any carrier running a commercial motor vehicle in interstate commerce needs one. Under 49 CFR 390.5T, that means a vehicle of 10,001 pounds or more, one designed or used to carry more than 8 passengers for pay or more than 15 without pay, or one hauling placarded hazardous materials.
Not every item applies to every operation. Drug and alcohol testing under Part 382 covers drivers who need a CDL (382.103), while driver qualification and vehicle maintenance rules start at the 10,001-pound line.
New carriers face a deadline on top of the calendar: the new entrant safety audit samples these same files. Our new entrant safety audit checklist covers what FMCSA reviews and what fails it. This page is the year-round version.
What goes in the company file?
The company file holds the registrations and insurance that let you operate at all. Each one has its own renewal date.
| Item | When | Rule |
|---|---|---|
| MCS-150 update | Before you start, then every 24 months by your USDOT number's last two digits | 49 CFR 390.19T |
| Proof of liability insurance (MCS-90 or MCS-82) | Kept at your principal place of business; at least $750,000 for for-hire general freight at 10,001 pounds or more | 49 CFR 387.7, 387.9 |
| UCR registration | Every year, before January 1 of the registration year | UCR Plan |
| IFTA return | Quarterly, by the last day of the month after the quarter | IFTA Articles R960 |
| Form 2290 (55,000 pounds or more) | By the last day of the month after first use in each July-to-June period | IRS Form 2290 |
| Accident register | Keep 3 years after each accident | 49 CFR 390.15 |
One date has moved. During the switch to FMCSA's Motus registration system, FMCSA has suspended enforcement of biennial updates, and the inactivation of USDOT numbers, for updates due on or after June 1, 2026 (FMCSA). That buys time, not an exemption. Our MCS-150 biennial update guide covers filing it in Motus.
Interstate carriers also need a process agent on file for each state they operate in (FMCSA), and 2027 UCR fees start at $55 for 0 to 2 vehicles (UCR Plan).
What goes in each driver's file?
Each driver needs a driver qualification file, kept for as long as the driver works for you and three years after (49 CFR 391.51). Our DQF checklist lists every document in it. For this checklist, what matters are the recurring items:
- Driving record: obtain each driver's motor vehicle record and review it at least once every 12 months (391.25).
- Medical certification: at least every 24 months, or every 12 months under the insulin-treated diabetes or alternative vision standards (391.45).
- Hours of service: records of duty status and supporting documents kept at least 6 months (395.8(k)).
A file can be complete while the driver is no longer qualified, because licenses get suspended between reviews. Driver compliance tracking covers how to catch that before dispatch does.
What does the drug and alcohol file need?
It needs proof that every CDL driver was cleared before driving and stays in a random program while employed. The checklist items:
- A verified negative pre-employment drug test, unless a narrow exception applies, before the driver's first safety-sensitive work (382.301).
- A full pre-employment Clearinghouse query before hire, and a query on every driver at least once a year (382.701).
- Random testing of at least 50 percent of average driver positions for drugs and 10 percent for alcohol; FMCSA kept both rates for 2026 (DOT ODAPC).
- Records kept by type: five years for positive results, refusals, and annual summaries; two years for collection records; one year for negatives (382.401).
An owner-operator who employs only himself must still be in a random pool of two or more drivers, usually through a consortium. Our DOT drug and alcohol testing program guide walks through setting one up.
What goes in each vehicle's file?
Each vehicle needs its inspection, repair, and maintenance history, kept where the vehicle is housed or maintained.
| Record | How long | Rule |
|---|---|---|
| Inspection, repair, and maintenance records | 1 year, and 6 months after the vehicle leaves your control | 49 CFR 396.3(c) |
| Annual inspection report | 14 months from the inspection; proof also rides on the vehicle | 49 CFR 396.17, 396.21 |
| Driver vehicle inspection reports with defects, and the repair certification | 3 months | 49 CFR 396.11 |
What DOT documents must be in the truck?
The documents required in the vehicle are the ones an officer can ask for at the roadside. Check each cab for:
- The driver's license for the vehicle class, a CDL where one is required (383.23).
- The apportioned cab card for IRP-registered vehicles, required by IRP Plan Section 605 (California DMV IRP handbook).
- A copy or electronic image of the IFTA license, with decals on both sides of the cab (IFTA Articles).
- The ELD information packet: a data transfer sheet, a malfunction sheet, and blank graph-grid logs for at least 8 days (395.22(h)).
- Proof of the annual inspection, as a copy of the report or a qualifying decal (396.17(c)).
- For leased equipment, a copy of the lease or the carrier's statement (376.11(c)(2)). For hazmat, shipping papers within the driver's reach (177.817(e)).
Does the driver still carry a medical card?
It depends on the license. Since June 23, 2025, CDL and permit holders do not need to carry the medical certificate, because FMCSA now sends medical results electronically to the state licensing agency (391.41). As of October 12, 2026, a paper certificate no longer counts as proof for drivers licensed outside Alaska, which keeps a 60-day paper option until October 12, 2027.
Drivers who do not need a CDL still carry the original or a copy, and anyone with a medical variance carries that document too. For U.S. carriers, federal rules keep proof of insurance at your office, but states can set their own proof rules, so check yours.
How to run the checklist as a calendar
Sort every item by how often it comes due, then give each line one owner.
| How often | What to check |
|---|---|
| Every trip | Pre-trip check, defect reports and repairs, hours-of-service records, cab documents |
| Every quarter | IFTA return |
| Every 12 months | Annual inspection per vehicle, driving record review, Clearinghouse query, random testing on pace, UCR |
| Every 24 months or sooner | Medical certification per driver, MCS-150 update |
| On an event | New hire, accident, vehicle added or sold, lease signed, address change |
The event row is where most gaps start, because nothing on a calendar reminds you. Tie each event to a short checklist of its own: a new hire triggers the test, the query, and the file; an accident triggers the register entry.
If you would rather hand off the tracking, our compliance programs cover driver files, CSA monitoring, and a DOT mock audit.
