Preparing for a DOT audit is essential for every trucking company, regardless of fleet size. Federal compliance reviews can occur with little notice, and poor preparation often leads to violations, fines, or out-of-service orders.
The good news is that with a structured checklist and consistent internal reviews, fleets can confidently navigate the process and reduce compliance risks.
This guide explains how to prepare for a federal safety review, what inspectors typically examine, and how to avoid costly Hours of Service penalties.
What Is a DOT Audit?
A DOT audit, also known as an FMCSA compliance audit, is a formal evaluation of a carrier’s safety practices and records. These audits are designed to ensure motor carriers follow federal safety regulations.
Common triggers include:
- New carrier registration
- Poor CSA scores
- Roadside inspection violations
- Safety complaints or enforcement concerns
The goal is to verify that carriers operate safely and maintain required documentation.
DOT Audit Preparation Checklist (Step-by-Step)
1. Organize Driver Qualification Files (DQFs)
Incomplete driver files are one of the most common compliance failures.
Each Driver Qualification File should include:
- Valid CDL and medical certificate
- Driver application and employment history
- Road test certificate or equivalent
- Annual Motor Vehicle Record (MVR) review
Missing or outdated records frequently result in violations during a compliance review.
2. Review Hours of Service and Driver Logs
Hours of Service compliance is a major focus during any safety audit.
Check for:
- Accurate driver logs (paper or ELD)
- Proper use of personal conveyance and yard move
- Supporting documents matching log entries
- Records retained for at least six months
Routine log reviews help fleets prevent HOS-related fines.
3. Verify ELD Compliance
For fleets using electronic logging devices, inspectors closely examine ELD data.
Confirm that:
- Devices meet FMCSA certification standards
- Drivers are trained on correct ELD operation
- Unassigned driving events are reviewed and resolved
- Log edits include proper annotations
ELD-related errors are a common trigger for enforcement action.
4. Inspect Vehicle Maintenance Records
Auditors review maintenance documentation to confirm vehicles are safe for operation.
Required records include:
- Preventive maintenance schedules
- Inspection, repair, and maintenance reports
- Annual vehicle inspection documentation
Incomplete or disorganized maintenance files can result in serious violations.
5. Review Insurance and Accident Records
Compliance inspections also assess financial responsibility and safety history.
Be prepared with:
- Active insurance certificates
- Accident register covering the past three years
- Post-accident drug and alcohol testing records
Missing documentation in this area often raises red flags.
6. Confirm Drug and Alcohol Testing Compliance
Drug and alcohol testing programs are mandatory for CDL drivers.
Ensure that:
- Drivers are enrolled in a compliant testing program
- Random testing records are current
- Pre-employment and post-accident tests are documented
Non-compliance here frequently leads to severe penalties.
