How to File an FMCSA Complaint Against a Carrier — Step by Step

You Have the Right to File a Complaint

The Federal Motor Carrier Safety Administration (FMCSA) is the federal agency responsible for regulating commercial motor vehicle safety and the trucking industry. When a carrier violates federal regulations — whether through illegal deductions, coercion, or safety violations — drivers have the right to file a formal complaint. Filing a complaint is free, confidential, and can lead to federal enforcement action.

What the FMCSA Can and Cannot Do

Before you file, it is important to understand the scope of FMCSA authority. The FMCSA can investigate and take enforcement action for:

• Violations of the Truth in Leasing regulations (49 CFR Part 376), including improper deductions and failure to provide settlement documentation
• Coercion — when a carrier pressures a driver to violate federal safety regulations
• Hours of service violations
• Drug and alcohol testing violations
• Safety violations and out-of-service orders

The FMCSA cannot resolve individual pay disputes, enforce employment contracts, or award damages. For those issues, drivers may need to pursue state labor board complaints or civil litigation. However, an FMCSA complaint creates an official record of carrier misconduct that can support other legal actions.

How to File a Complaint: Step by Step

Step 1: Gather your documentation. Before filing, collect all relevant documents: your lease or employment agreement, settlement sheets, rate confirmations, and any written communications with the carrier. The more specific your complaint, the more likely it is to result in an investigation.

Step 2: Go to the FMCSA National Consumer Complaint Database. Visit nccdb.fmcsa.dot.gov. This is the official portal for filing complaints against motor carriers. You will need the carrier's DOT number, which appears on their trucks and can be looked up at safer.fmcsa.dot.gov.

Step 3: Select the complaint category. Choose the category that best describes the violation. For lease and pay violations, select "Leasing Regulations." For safety coercion, select "Coercion." You can file multiple complaints if the carrier violated multiple regulations.

Step 4: Describe the violation in detail. Be specific. Include dates, dollar amounts, and the specific regulation you believe was violated. Attach copies of your supporting documents. Vague complaints are harder to investigate.

Step 5: Submit and record your complaint number. After submitting, you will receive a complaint number. Save it. You can use it to check the status of your complaint and reference it in any follow-up communications.

What Happens After You File

The FMCSA reviews complaints and may contact the carrier for a response. If a pattern of violations is identified, the FMCSA may open a formal investigation, conduct a compliance review, or issue civil penalties. Individual complaints are most effective when combined with complaints from multiple drivers — which is why submitting your case to BigRigNation.com matters. We track patterns across carriers and can connect drivers who have experienced the same violations.

Additional Complaint Channels

In addition to the FMCSA, drivers can file complaints with:

• State labor boards: For wage theft and employment law violations
• State attorney general offices: For consumer protection violations
• The Department of Labor: For misclassification as independent contractors when the work relationship is actually employment
