For motor carriers, staying compliant with U.S. Department of Transportation (DOT) and Federal Motor Carrier Safety Administration (FMCSA) regulations is an important part of operating safely and legally. One way federal regulators evaluate a carrier’s safety practices is through DOT audits.
A DOT audit reviews a motor carrier’s records, procedures, and safety management controls to determine whether the company is meeting applicable federal safety requirements. Depending on the situation, FMCSA may conduct different types of reviews or audits.
Understanding the different DOT audit types can help carriers prepare their records, identify compliance gaps, and maintain better safety practices.
In this guide, we will explain four crucial types of DOT audits and what motor carriers should know about each one.
What Is a DOT Audit?
A DOT Safety Audit is a review of a motor carrier’s operations and records. The purpose is to determine whether the carrier has basic safety management controls and is following applicable FMCSA requirements.
During an audit, investigators may review areas such as:
- Driver qualification files
- Drug and alcohol testing records
- Hours-of-service records
- Vehicle maintenance
- Accident records
- Insurance and operating authority
- Controlled substance and alcohol testing programs
- Safety procedures and documentation
Keeping accurate and organized records can make the audit process easier and help carriers identify potential compliance problems before they become serious issues.
1. New Entrant Safety Audit
A New Entrant Safety Audit is generally conducted for certain new motor carriers after they begin operating.
New entrants are expected to demonstrate that they have the basic safety management controls necessary to operate safely. FMCSA uses the audit to determine whether the carrier is complying with applicable safety regulations.
What Does a New Entrant Audit Review?
Depending on the carrier's operations, the review may include:
- Driver qualification requirements
- Commercial driver’s license requirements
- Hours-of-service compliance
- Vehicle inspection and maintenance
- Insurance requirements
- Accident records
- Drug and alcohol testing
- Required operating records
A carrier that fails to demonstrate adequate safety management controls may face further regulatory action.
How Can New Carriers Prepare?
New carriers should establish compliance procedures from the beginning rather than waiting for an audit notice.
They should maintain complete driver files, keep required vehicle maintenance records, document inspections, and ensure that their DOT drug and alcohol testing program is properly managed.
For employers subject to DOT drug and alcohol testing, required testing may include pre-employment, random, post-accident, reasonable-suspicion, return-to-duty, and follow-up testing when applicable.
2. Compliance Review
A Compliance Review is a more comprehensive examination of a motor carrier’s safety performance and regulatory compliance.
FMCSA may conduct a compliance review when there are concerns about a carrier’s safety performance or when certain conditions require a more detailed examination.
Unlike a limited audit, a compliance review can examine multiple areas of a carrier’s operations.
What Can a Compliance Review Examine?
Investigators may review:
- Driver qualification files
- Hours-of-service records
- Vehicle maintenance
- Accident records
- Controlled substance and alcohol testing
- Commercial driver licensing
- Financial responsibility
- Operating authority
- Safety management practices
The purpose is to determine whether the carrier is operating in accordance with applicable regulations and whether its safety controls are effective.
Why Is It Important?
A compliance review can identify patterns of non-compliance rather than focusing on only one isolated issue.
For example, missing drug-testing records, incomplete driver qualification files, repeated vehicle maintenance problems, or HOS violations may indicate weaknesses in a carrier’s overall safety management system.
Maintaining accurate records throughout the year is therefore much more effective than trying to organize everything after receiving an audit notice.
3. Focused Investigation
A Focused Investigation is a targeted review that concentrates on specific safety-related areas.
Instead of examining every aspect of a carrier’s operation, investigators may focus on violations, safety concerns, or areas identified through available safety information.
For example, if a carrier has concerns related to driver qualification, hours of service, vehicle maintenance, or drug and alcohol testing, the investigation may concentrate on those areas.
What Happens During Focused Investigation?
Investigators may request specific documents and records related to the area being examined.
For example, if drug and alcohol compliance is being reviewed, the carrier may need to provide documentation showing that required testing and recordkeeping procedures are being followed.
This can include:
- Testing records
- Random testing documentation
- Driver testing history
- Alcohol testing records
- Employer records
- Required policy documentation
- Return-to-duty and follow-up testing records, when applicable
A focused investigation allows regulators to examine a particular safety concern without necessarily conducting a full review of every part of the carrier’s operation.
4. Off-Site Investigation
An Off-Site Investigation allows FMCSA to review certain safety and compliance information without conducting the entire examination at the carrier’s physical location. The carrier may be asked to submit requested records electronically or through another approved method.
This approach can allow investigators to evaluate specific compliance areas based on information and documents provided by the carrier.
What Records May Be Requested?
Depending on the purpose of the investigation, requested documents may include:
- Driver qualification records
- Hours-of-service records
- Vehicle maintenance documents
- Accident information
- Drug and alcohol testing records
- Inspection records
- Insurance documentation
- Other safety-related records
Because an off-site investigation may rely heavily on submitted documentation, carriers should ensure that their records are accurate, complete, current, and easy to locate.
DOT Audit vs. DOT Compliance Review
The terms DOT audit and DOT compliance review are sometimes used interchangeably, but they can refer to different levels or types of regulatory examination.
A safety audit generally evaluates whether a carrier has basic safety management controls. A compliance review can be broader and may examine a carrier’s overall compliance with applicable regulations.
The exact scope depends on why FMCSA is conducting the review and what information is being examined.
Regardless of the type of review, organized records and consistent safety procedures are essential.
Common Compliance Areas During DOT Reviews
Although the scope of a review can vary, several areas commonly receive attention.
Driver Qualification
Carriers must maintain required driver qualification documentation and ensure that drivers meet applicable requirements.
Incomplete or outdated driver files can create compliance problems.
Hours of Service
Carriers and drivers must follow applicable FMCSA Hours-of-Service (HOS) regulations. Required records should accurately reflect drivers’ activities.
Vehicle Maintenance
Carriers are responsible for maintaining vehicles in safe operating conditions. Maintenance records should be properly documented and retained as required.
Drug and Alcohol Testing
DOT-regulated employers must follow applicable DOT drug and alcohol testing regulations.
Testing programs should be properly managed, and required records must be maintained according to federal requirements.
Accident Records
Carriers should maintain appropriate accident documentation and ensure that required reports and records are completed accurately.
How Can Motor Carriers Prepare for a DOT Audit?
Preparing for an audit should be an ongoing process rather than a last-minute activity.
Keep Records Organized
Create a consistent filing system for drivers, vehicles, accidents, HOS, and drug and alcohol records. Digital systems can make it easier to locate documents when they are requested.
Review Driver Files Regularly
Conduct periodic internal reviews to identify missing or outdated documents before an official review occurs.
Maintain Drug Testing Compliance
Make sure required DOT testing is completed according to applicable regulations. Employers should also ensure that random testing programs are properly managed, and that required documentation is maintained.
Monitor Vehicle Maintenance
Keep inspection, repair, and maintenance records organized and up to date.
Train Responsible Staff
Employees responsible for safety and compliance should understand their duties and know where required records are maintained.
Conduct Internal Compliance Checks
Regular internal reviews can help identify gaps before they become regulatory problems.
