DOT compliance refers to the rules and standards that ensure commercial drivers, vehicles, and carriers operate safely and legally on U.S. roads.
Key DOT regulations cover driver qualifications, medical exams, vehicle maintenance, hours of service, and controlled-substance testing. The FMCSA can audit your records at any time, so keeping everything current and accurate is essential.

But with regulations that change often and paperwork that piles up fast, it’s easy to miss something critical. This DOT Compliance Checklist walks through everything you need to stay compliant, plus how Foley’s digital platform can simplify the compliance review process.
A DOT audit is a review conducted by the FMCSA to ensure a carrier is following federal safety and compliance regulations. During an audit, investigators may review driver qualification files, Hours of Service logs, drug and alcohol testing records, medical certificates, DVIRs, and vehicle maintenance records.
DOT audits can happen for several reasons, including:
The best way to prepare is to keep all compliance documentation organized, current, and audit-ready at all times. Automated compliance systems can help fleets track deadlines, and centralize records to reduce the risk of violations during an FMCSA review.
Foley Solution:
Foley’s DOT compliance software keeps every record organized, secure, and accessible—helping you stay audit-ready year-round.
Every driver who operates a Commercial Motor Vehicle (CMV) must have a complete and up-to-date Driver Qualification File. Missing or incomplete documents are among the most common audit violations.
Your DQF must include:
Completed driver application
Copy of current CDL
Three-year driving history (Motor Vehicle Record)
Previous-employer verifications
Medical Examiner’s Certificate (DOT medical card)
Annual MVR and review
Annual driver-certification of violations
Foley Tip:
Foley’s digital driver file management automatically tracks document expirations and notifies you before deadlines—no binders or spreadsheets required.
All CDL drivers must maintain a valid Medical Examiner’s Certificate (MEC) issued by a certified examiner and filed with their state licensing agency.
Requirements:
Valid certificate linked to the driver’s MVR
Renewal before expiration (typically every 24 months)
Immediate updates to the carrier’s records
Foley Tip:
Foley’s DOT physical-tracking tools help ensure every driver’s medical card is current and correctly attached to their record.
An MVR reveals each driver’s licensing status and recent violations. You must run one:
At hire
Annually for each driver
Why it matters:
A license suspension or serious violation can appear anytime. Waiting a full year to check increases your risk.
Foley Solution:
Continuous MVR Monitoring alerts you the moment a new violation appears, helping you prevent accidents and protect your CSA score.
All CDL drivers in safety-sensitive positions must participate in a compliant drug and alcohol testing program.
Your program must include:
Pre-employment testing
Random testing throughout the year
Return-to-duty and follow-up testing
You must also register with and report to the FMCSA Clearinghouse.
Foley Solution:
Foley’s Drug & Alcohol Testing Program automates random selection, scheduling, and reporting—keeping you compliant without manual tracking.
Drivers must follow federal HOS limits that regulate how long they can drive before taking required breaks.
To comply:
Use an Electronic Logging Device (ELD) to record driving time.
Retain HOS records for six months.
Regularly review logs for accuracy or falsification.
Foley Tip:
Use internal audits to compare ELD logs with dispatch and fuel data. This helps catch errors before inspectors do.
Proper vehicle care is critical to DOT compliance and safety regulations.
Carriers must:
Conduct daily pre- and post-trip inspections.
Keep proof of annual DOT inspections.
Maintain maintenance and repair records.
Why it matters:
Incomplete inspection records are a top cause of roadside violations.
Foley Tip:
Store your maintenance files digitally alongside driver records for fast retrieval during audits.
If you transport hazardous materials, additional requirements apply.
You must have:
Proper Hazmat endorsements
Training and certification records
Correct placards and shipping papers
Even if you only occasionally haul HazMat, documentation must be consistent and accessible.
The FMCSA’s Compliance, Safety, Accountability (CSA) program evaluates fleets on inspection results, violations, and crashes.
Why it matters:
Poor CSA scores can raise insurance costs or cause brokers to deny loads.
Foley Tip:
Use continuous MVR monitoring and driver training to prevent violations and maintain a strong safety profile.
Compliance isn’t a one-time task. Regular training and refreshers keep your team aware of changing FMCSA and DOT rules.
Recommended actions:
Conduct periodic driver-safety meetings.
Review DQFs quarterly.
Update internal policies annually.
Fostering a culture of compliance ensures small problems never grow into violations.
Stay one step ahead of your next audit. Foley’s DOT and FMCSA Compliance Checklist gives you a simple, step-by-step way to track every requirement -from driver files to drug testing - in one place.
For many fleet managers, keeping track of driver files, inspections, medical certificates, maintenance records, and HOS compliance manually can quickly become overwhelming.
Staying DOT compliant not only reduces the risk of violations and audits, but also helps improve overall fleet safety and protect a carrier’s safety score in the FMCSA’s Safety Measurement System (SMS).
Using this DOT FMCSA compliance checklist, combined with digital tools like Foley’s all-in-one platform, will bring every compliance requirement (driver files, MVRs, drug testing, and medical certificates) into one secure system to ensure you are ready for your audit.
Key benefits:
Foley’s DOT compliance software keeps fleets audit-ready with automated recordkeeping, digital driver files, and real-time alerts.

DOT compliance refers to following the safety regulations established by the Federal Motor Carrier Safety Administration (FMCSA) for commercial motor vehicles and drivers. These rules cover areas such as driver qualification files, vehicle maintenance, Hours of Service (HOS), drug and alcohol testing, medical certifications, and safety recordkeeping.
Yes. If your company operates vehicles that meet Commercial Motor Vehicle (CMV) requirements, you must comply with FMCSA regulations regardless of fleet size. Even owner-operators and small fleets are responsible for maintaining driver records, safety documentation, and compliance programs.
Retention periods vary depending on the record type. Many compliance records must be kept for at least three years, while some drug and alcohol testing records must be retained for five years. Maintenance records, DVIRs, and Hours of Service documentation may also have separate retention requirements under FMCSA regulations.
During a DOT audit, FMCSA investigators review your compliance records to verify that your fleet is operating safely and following federal regulations. This may include reviewing DQFs, drug and alcohol testing records, maintenance logs, DVIRs, medical certificates, and Hours of Service records. Organized digital documentation can make the process significantly easier.
Some of the most common violations involve incomplete Driver Qualification Files, Hours of Service issues, expired medical certificates, and missing vehicle inspection or maintenance records. Many of these violations are preventable with proactive monitoring and automated compliance tracking.
