A DOT audit doesn't have to be stressful. Most of what the auditor wants is paperwork you should already have: logs, supporting documents, driver files and maintenance records. The trouble starts when those records are scattered, incomplete or missing. This checklist walks through what's reviewed and how long each record has to be kept, so you can get organized before anyone asks.

What Auditors Check

FMCSA runs two main kinds of review under 49 CFR Part 385:

New entrant safety audit. Every new interstate carrier is in an 18 month monitoring period. A safety audit must be done within 12 months of getting a USDOT number for property carriers, and within 120 days for passenger carriers.
Compliance review or investigation. A deeper look at an established carrier, often triggered by high CSA scores, a crash or a complaint. It can lead to a safety rating of satisfactory, conditional or unsatisfactory.

Both cover the same main areas: hours of service, driver qualification, drug and alcohol testing, vehicle maintenance and inspection, insurance and crash records.

Automatic failure items

For new entrants, some violations mean you automatically fail the safety audit. Part 385.321 lists 16 of them. They include:

Not having a drug and alcohol testing program, or no random testing program.
Using a driver who tested positive, refused a test or had a 0.04 or higher alcohol level.
Knowingly using a driver without a valid CDL, or a disqualified driver.
Knowingly using a physically unqualified driver.
Operating without the required insurance.
Failing to require drivers to make a record of duty status. This one needs a threshold: 51% or more of examined records.
Operating a vehicle placed out of service before repairs are made, or not fixing out of service defects listed on a DVIR.
Using a vehicle that hasn't had its periodic inspection.

Fail and FMCSA will move to revoke your new entrant registration unless you fix the problems. So start with these.

ELD Records

The hours of service part of the audit focuses on your logs. Have these ready:

ELD records of duty status for every driver for the past six months. Under 49 CFR 395.30, carriers must keep ELD records and a backup copy on a separate device for six months.
Edit history and annotations, showing who changed what and why.
Unassigned driving records, and how each one was resolved.
Malfunction records and the paper logs drivers kept during any malfunction.
Records for any drivers using an exemption, such as short haul time records.

Make sure you can export logs quickly from your ELD portal. Auditors may ask for a sample of drivers and dates, and being able to pull them in minutes makes a good impression.

Supporting Documents

Logs alone aren't enough. You also have to keep supporting documents that let the auditor check whether the logs are accurate. Under 49 CFR 395.11, these fall into categories such as:

Bills of lading, itineraries, schedules or similar documents showing trip origin and destination.
Dispatch records, trip records or equivalent documents.
Expense receipts related to on duty time, such as fuel and tolls.
Electronic mobile communication records sent through fleet management systems.
Payroll records, settlement sheets or similar documents showing what the driver was paid.

You don't need to keep more than eight supporting documents per driver for each 24 hour period. Supporting documents must be kept for six months, the same as logs.

Driver Files

Every driver needs a driver qualification file. Under 49 CFR 391.51, keep the file for as long as the driver works for you and for three years after they leave. Checklist:

Employment application.
Motor vehicle record from each state at hiring and the annual review.
Road test certificate or equivalent.
Medical examiner's certificate, kept current.
Annual review of driving record.
Safety performance history from previous employers.
Drug and alcohol testing records, including Clearinghouse queries.

Some items can be removed three years after the date they were completed. Check the rule for which ones.

Vehicle Records

Maintenance and inspection records are another big area. Under 49 CFR 396.3, keep them where the vehicle is housed or maintained for one year, and for six months after the vehicle leaves your control. Include:

Identification for each vehicle, such as unit number, make, VIN and tire size.
A schedule of inspection and maintenance.
Records of inspections, repairs and maintenance.
Driver vehicle inspection reports (DVIRs) and proof that defects were fixed. Our DVIR guide covers the details.
Annual periodic inspection reports for every vehicle.

Printable Checklist

[ ] Drug and alcohol program in place, with random testing
[ ] Clearinghouse queries done for every driver
[ ] Insurance current and on file with FMCSA
[ ] Six months of ELD logs and backups for every driver
[ ] Edits, annotations and unassigned driving reviewed
[ ] Supporting documents kept and organized by driver and date
[ ] Complete driver qualification file for each driver
[ ] Medical certificates current
[ ] Maintenance records for every vehicle
[ ] DVIRs with repairs certified
[ ] Annual inspections current
[ ] Accident register for the past three years

Keep the accident register too. Carriers must keep records of reportable crashes for three years, and auditors often compare it against crash reports in FMCSA data.

Organized records also save the auditor time, which keeps the review shorter for everyone.

Tips

Do a mock audit once a year. Pick three drivers and a random week, pull every record and check that it all lines up. Compare the ELD logs with fuel receipts and bills of lading. Gaps you find yourself are much easier to fix than gaps an auditor finds.
