DOT Audit Checklist for Small Carriers (2026)

A DOT audit is an FMCSA review of a motor carrier’s safety records. For a carrier with a new USDOT number it is the New Entrant Safety Audit under 49 CFR Part 385, Subpart D. FMCSA says it takes place within 12 months after operations begin, usually at your principal place of business.

The auditor samples your records against the rules in Parts 382, 387, 390, 391, 395 and 396. Pass, and FMCSA keeps monitoring you. Fail, and your USDOT registration is revoked unless you fix what the notice lists, in 60 days for most carriers.

What a DOT audit is, and when it happens

There are two kinds. The safety audit is for new entrants. FMCSA’s program page says a New Entrant is monitored during an initial 18-month period, and its FAQ says “A Safety Audit will be conducted within 12 months after the New Entrant begins operations.” The rule adds that the audit comes once you have enough records for FMCSA to judge your safety controls, generally at least 3 months in (49 CFR 385.307).

A compliance review or intervention can happen at any time FMCSA safety data indicates problems, to a carrier of any age. Both are generally held at the principal place of business. The audit reviews driver qualification, driver duty status, vehicle maintenance, the accident register, and controlled substances and alcohol testing (49 CFR 385.311).

The purpose of the safety audit, in the rule’s words, is to provide educational and technical assistance and to gather the safety data FMCSA needs to assess your basic safety management controls (49 CFR 385.309). Our small-fleet DOT guide explains who needs a USDOT number and why the six record sets matter. This page is the walk-through.

What fails the audit

49 CFR 385.321(b) lists 16 regulations. A new entrant automatically fails if it is found in violation of any one of them, under the guideline in the right-hand label. Here is the list as the rule states it.

§ 382.115(a)/(b) · Single occurrenceFailing to implement an alcohol and/or controlled substances testing program
§ 382.201 · Single occurrenceUsing a driver known to have an alcohol content of 0.04 or greater to perform a safety-sensitive function
§ 382.211 · Single occurrenceUsing a driver who has refused to submit to an alcohol or controlled substances test required under part 382
§ 382.215 · Single occurrenceUsing a driver known to have tested positive for a controlled substance
§ 382.305 · Single occurrenceFailing to implement a random controlled substances and/or alcohol testing program
§ 383.3(a)/383.23(a) · Single occurrenceKnowingly using a driver who does not possess a valid CDL
§ 383.37(b) · Single occurrenceKnowingly allowing, requiring, permitting, or authorizing an employee to operate a commercial motor vehicle with a CLP or CDL which is disqualified by a State, has lost the right to operate a CMV in a State or who is disqualified to operate a commercial motor vehicle
§ 383.51(a) · Single occurrenceKnowingly allowing, requiring, permitting, or authorizing a driver to drive who is disqualified to drive a commercial motor vehicle
§ 387.7(a) · Single occurrenceOperating a motor vehicle without having in effect the required minimum levels of financial responsibility coverage
§ 387.31(a) · Single occurrenceOperating a passenger carrying vehicle without having in effect the required minimum levels of financial responsibility
§ 391.15(a) · Single occurrenceKnowingly using a disqualified driver
§ 391.11(b)(4) · Single occurrenceKnowingly using a physically unqualified driver
§ 395.8(a) · 51% or more of examined recordsFailing to require a driver to make a record of duty status
§ 396.9(c)(2) · Single occurrenceRequiring or permitting the operation of a commercial motor vehicle declared “out-of-service” before repairs are made
§ 396.11(a)(3) · Single occurrenceFailing to correct out-of-service defects listed by driver in a driver vehicle inspection report before the vehicle is operated
§ 396.17(a) · 51% or more of examined recordsUsing a commercial motor vehicle not periodically inspected

Past the automatic list, a carrier can also fail for a lack of basic safety management controls described in Appendix A to Part 385 (49 CFR 385.321(a)). FMCSA mails written notice within 45 days after the audit. For most carriers the corrective actions are due within 60 days of the notice. Passenger carriers that transport 9 or more passengers (including the driver) for compensation, and hazmat carriers, have 45 days. If the work is not done, the registration is revoked and the operation is placed out of service (49 CFR 385.319).

Driver qualification files

49 CFR Part 391

Employment application for each driver, completed and signed by the driver (§ 391.21).
Motor vehicle record (MVR) requested within 30 days of the date employment begins, covering the prior 3 years, and placed in the file within the same 30 days (§ 391.23).
Prior-employer safety performance history for the preceding 3 years from DOT-regulated employers, or documentation of your good-faith efforts, filed within 30 days of hire (§ 391.23).
Road test certificate, or a copy of the license or certificate you accepted as its equivalent (§ 391.31, § 391.51).
Annual MVR inquiry and review at least once every 12 months, with a note of who did the review and the date (§ 391.25).
Medical examiner’s certificate on file. A driver must have been examined and certified within the preceding 24 months; the rule sets 12 months for some conditions (§ 391.45).
Keep the file for as long as the driver works for you and for three years after. The MVR and the annual review note may come out three years after they were executed (§ 391.51).

Drug and alcohol program

49 CFR Part 382 and the Clearinghouse

A testing program is in place. Failing to implement an alcohol and controlled substances program is an automatic-fail item (§ 382.115).
Pre-employment controlled substances test with a verified negative result in hand before the driver performs a safety-sensitive function (§ 382.301).
Every CDL driver is in a random pool. Part 382 sets minimum annual rates of 50 percent of average driver positions for controlled substances and 10 percent for alcohol, and lets the FMCSA Administrator change them (§ 382.305).
Random selections are spread through the calendar year and tested in the period they were selected. FMCSA’s Q&A says a driver chosen in the first quarter, which runs January 1 to March 31, who is tested in April is a violation (FMCSA random testing Q&A).
Owner-operators with one CDL driver who is not leased to another carrier use a consortium for random testing, per the same FMCSA Q&A.
Clearinghouse pre-employment query, a full query with the driver’s specific consent, before the driver performs a safety-sensitive function (§ 382.701).
Clearinghouse annual query for every driver at least once per year. A limited query with the driver’s consent satisfies it; if it shows information exists, run a full query within 24 hours (§ 382.701).
Employer registered in the Clearinghouse and a record of each query kept for 3 years. The rule says a valid registration fulfills the recordkeeping requirement (§ 382.701; register at clearinghouse.fmcsa.dot.gov).

Hours of service and ELD

49 CFR Part 395

Every driver who must keep a record of duty status does. Failing to require one is an automatic-fail item when 51 percent or more of the records examined are in violation (§ 395.8).
Electronic logging device (ELD) in use, unless a paper-log exception applies: records of duty status needed on no more than 8 days in any 30-day period, driveaway-towaway operations, or a vehicle built before model year 2000 (§ 395.8).
Your ELD model appears on FMCSA’s ELD list (eld.fmcsa.dot.gov/list).
ELD information packet in each vehicle: a data-transfer instruction sheet, a malfunction instruction sheet, and blank graph-grids for at least 8 days (§ 395.22).
Records of duty status and supporting documents kept at least 6 months from the date of receipt (§ 395.8).
ELD back-up copy kept for 6 months on a device separate from the one holding the original data (§ 395.22).
Drivers submit logs to you within 13 days of the 24-hour period they cover, and carry the previous 7 days (§ 395.8).

Vehicle maintenance and inspection

49 CFR Part 396

A file for each vehicle you control with inspection, repair and maintenance records, kept where the vehicle is housed or maintained for 1 year and for 6 months after it leaves your control (§ 396.3).
Annual inspection done within the preceding 12 months on every vehicle, with documentation of it on the vehicle. Not periodically inspecting is an automatic-fail item at the 51 percent threshold (§ 396.17, § 385.321).
Annual inspection reports kept for 14 months from the date of the report (§ 396.21).
Driver vehicle inspection reports (DVIRs), the certification of repairs and the certification of the driver’s review kept for three months (§ 396.11).
Defects listed on a DVIR are fixed before the vehicle is operated. Not correcting out-of-service defects is an automatic-fail item (§ 396.11).
No out-of-service vehicle is dispatched before repairs, which is also an automatic-fail item (§ 385.321).

Insurance and financial responsibility

49 CFR Part 387

Coverage meets the minimum for what you haul. The table in § 387.9 lists $750,000 for for-hire carriers of nonhazardous property in vehicles of 10,001 pounds GVWR or more, $1,000,000 for oil and the hazardous materials in entry 3, and $5,000,000 for the bulk hazardous materials in entry 2.
Policy and endorsement are current. Operating without the required minimum financial responsibility is an automatic-fail item (§ 387.7, § 385.321).
MCS-90 endorsement issued in the exact name of the motor carrier and written to stay in effect continuously until terminated (§ 387.15).

Accident register

49 CFR 390.15

Register kept for 3 years after the date of each accident (§ 390.15).
Each entry lists the date, the city or town (or nearest) and State, the driver’s name, the number of injuries, the number of fatalities, and whether hazardous materials other than fuel from the vehicle’s own tanks were released (§ 390.15).
Copies of every accident report required by a State or other governmental entity or your insurer are filed with the register (§ 390.15).
You know what counts. An accident under § 390.5 is an occurrence involving a commercial motor vehicle on a highway that results in a fatality, bodily injury that gets immediate medical treatment away from the scene, or disabling damage that requires a tow. The definition has exclusions, so read it.

Operating authority and registration

USDOT, MC and UCR

USDOT number active and the vehicles marked with it. FMCSA’s New Entrant page says carriers apply with form MCS-150, and for-hire carriers apply for operating authority with the OP-1 series (FMCSA New Entrant page).
Operating authority (MC number) in place if you are a for-hire carrier that is not exempt from commercial registration (same FMCSA New Entrant page).
MCS-150 biennial update filed on time and within 30 days of any change in your information (FMCSA biennial update FAQ).
Unified Carrier Registration (UCR) handled through the UCR Plan, created by the UCR Act (49 U.S.C. 14504a). Confirm the current-year window at plan.ucr.gov.

Hazmat, if you haul it

49 CFR Part 397

Read Part 397 (hazardous materials driving and parking rules) and use the higher insurance minimums in the § 387.9 table. Hazmat carriers also get 45 days, not 60, to fix a failed audit (§ 385.319). This checklist does not go further.

The random testing rates above are the minimums written in 49 CFR 382.305(b). The rule lets the FMCSA Administrator change them by Federal Register notice. We did not find a 2026 FMCSA notice changing them, but confirm the current rate with FMCSA or your testing consortium before you set your pool.

The dates that slip

These are the deadlines small carriers miss, because most are tied to a driver, a truck or a USDOT number rather than the calendar.

Item	When it is due	Source
MCS-150 biennial update	Every 24 months by the last day of the month set by the last digit of the USDOT number (1 is January through 9 is September, 0 is October). An odd next-to-last digit means odd-numbered years; even means even-numbered years. Also within 30 days of any change.	FMCSA FAQ (49 CFR 390.19)
Medical examiner’s certificate	Driver examined and certified within the preceding 24 months; 12 months for the conditions listed in the rule.	49 CFR 391.45
Annual MVR inquiry and review	At least once every 12 months for each driver.	49 CFR 391.25
Clearinghouse annual query	At least once per year for each driver subject to testing.	49 CFR 382.701(b)
Annual vehicle inspection	Each vehicle passes inspection at least once in the preceding 12 months.	49 CFR 396.17(c)
Random testing	Selections spread reasonably through the calendar year; a driver selected in a quarter must be tested in that selection period (Q1 runs January 1 to March 31).	49 CFR 382.305; FMCSA Q&A
New entrant audit	Within 12 months after operations begin; 18-month monitoring period.	FMCSA New Entrant page; 49 CFR 385.307
UCR	Set by the UCR Plan each year. Check the current window and fee.	plan.ucr.gov

How long to keep each record

Every period below comes from the eCFR section named in the right-hand column.

Record	Keep for	49 CFR
Driver qualification file	Employment plus 3 years	391.51(c)
Records of duty status and supporting documents	6 months from receipt	395.8(k)
ELD back-up copy	6 months, on a separate device	395.22
Driver vehicle inspection report	3 months	396.11
Vehicle maintenance records	1 year where housed or maintained, and 6 months after the vehicle leaves your control	396.3
Annual inspection report	14 months from the inspection	396.21(b)
Accident register	3 years from each accident	390.15(b)
Clearinghouse query records	3 years	382.701(e)
Alcohol and drug collection-process records	2 years (other records in § 382.401 run 5 years)	382.401

Before the auditor arrives

Put one binder or folder per driver together first. The driver qualification file is where the audit starts, and the rule says the file must be there for as long as the driver works for you and for three years after.
Pull a few months of logs and the supporting documents. The 6-month retention rule covers both.
Print your Clearinghouse query records and your random testing selections for the year.
Walk each truck. Is the annual inspection documentation on the vehicle, and are the DVIRs for the last three months filed?
Check the insurance certificate and the MCS-90 endorsement name against the name on your USDOT registration.
Open the accident register and compare it with the accident reports your insurer and State hold.
Confirm the USDOT record at FMCSA lists your current address, phone, email and power-unit count.

The rule requires you to make all records and documents available on request by a certified safety auditor (49 CFR 385.307(c)). Gaps are fixable before the audit and expensive after it.

Common Questions

How long do I have before my New Entrant Safety Audit?

FMCSA says a safety audit will be conducted within 12 months after the new entrant begins operations, and that a new entrant is monitored for 18 months after it gets a USDOT number. The rule adds that the audit happens once the carrier has been running long enough to have records to review, generally at least 3 months. FMCSA sends a letter explaining the next steps.

What automatically fails a DOT audit?

Sixteen violations in 49 CFR 385.321(b) fail a new entrant safety audit. Most count on a single occurrence, such as having no random testing program, using a driver who refused a test, or operating without the required insurance. Two, failing to require records of duty status and using vehicles not periodically inspected, only fail the audit when 51 percent or more of the records examined are in violation.

What records does the auditor ask for?

The audit reviews driver qualification, driver duty status, vehicle maintenance, the accident register, and controlled substances and alcohol testing (49 CFR 385.311). Insurance is checked too, because operating without the required coverage is an automatic-fail item. The rule requires you to make the records available when a certified auditor asks.

Do I need an ELD with one truck?

The ELD requirement in 49 CFR 395.8 follows the driver, not the fleet size. A carrier may use paper logs instead only for a driver who needs a record of duty status on no more than 8 days in any 30-day period, in certain driveaway-towaway operations, or in a vehicle built before model year 2000. Check any exception against the text of 395.8.

How long must I keep driver logs?

A motor carrier keeps records of duty status and supporting documents for at least 6 months from the date of receipt, and the driver carries the previous 7 consecutive days (49 CFR 395.8(k)). If you use an ELD, the back-up copy of the ELD records is kept 6 months on a separate device (49 CFR 395.22).

What is the Drug and Alcohol Clearinghouse?

It is the FMCSA database of drug and alcohol program violations by CDL drivers. Employers must run a pre-employment query and at least one query per year on every driver subject to testing, and keep a record of each query for 3 years (49 CFR 382.701). An employer with a valid registration meets that recordkeeping rule.

What happens if my carrier fails the audit?

FMCSA sends written notice within 45 days after the audit saying the USDOT new entrant registration will be revoked and operations placed out of service unless you take the listed actions. Most carriers have 60 days from the notice. Passenger carriers of 9 or more passengers and hazmat carriers have 45 days (49 CFR 385.319).

Is a compliance review the same as a new entrant audit?

No. A safety audit is the new entrant check of your safety management controls. FMCSA says compliance reviews and interventions can happen at any time its safety data indicates problems. Both are generally held at the principal place of business.
