How to File an FMCSA Complaint About an Unsafe Carrier

Last year, a reader emailed us after a moving company held her furniture hostage in a warehouse for three weeks -- demanding $2,400 more than the binding estimate she signed. She had no idea the federal government had a complaint process for exactly this situation. If you have ever watched an 18-wheeler swerve across lanes on the highway or gotten blindsided by a shady mover, an FMCSA complaint is one of the most concrete steps you can take. Below, we walk through the full process: what evidence to collect, how to file, and what realistically happens afterward.

When and Why You Should File an FMCSA Complaint

The FMCSA is the arm of the U.S. Department of Transportation that oversees roughly 500,000 active motor carriers and the household-goods moving industry. When you file a complaint, you are doing more than venting -- you are feeding data into the same Safety Measurement System (SMS) that determines which carriers get audited, fined, or shut down entirely. In fiscal year 2024, FMCSA opened over 7,500 investigations tied partly to consumer and driver complaints, so these reports genuinely move the needle.

One thing worth being upfront about: filing a complaint will not get you a refund check or fix your dented dresser. What it does is attach a permanent flag to that carrier's federal record. Stack enough flags and the carrier faces a full compliance review, civil penalties of up to $25,000 per violation, or loss of their operating authority altogether. We have seen carriers in our own database go from "active" to "revoked" within months once a pattern of complaints piled up.

Before filing, consider checking the trucking company's safety record to understand if there's a pattern of violations. Companies with poor safety scores are more likely to face enforcement action when complaints are filed.

Types of Complaints FMCSA Handles

The FMCSA accepts complaints in several categories, each handled through specific processes:

Safety Violations: This includes reckless driving, unsafe vehicles, drivers appearing impaired or fatigued, vehicles leaking hazardous materials, overweight trucks, and violations of hours-of-service rules. These complaints go directly to FMCSA's enforcement division and may result in roadside inspections or investigations.

Household Goods Moving Fraud: Moving company complaints are among the most common. These include hostage loads (refusing to deliver until you pay more than the estimate), damaged belongings, missing items, failure to deliver, unlicensed movers, and binding estimate violations. The FMCSA maintains a specialized household goods complaint database and works with state attorneys general on these cases.

Hazardous Materials Concerns: If you observe improper handling, storage, or transportation of hazmat materials, including leaking containers, missing placards, or unsafe loading practices, FMCSA investigates these as priority safety issues due to the potential for catastrophic accidents.

Coercion Complaints: Truck drivers can file complaints when carriers pressure them to violate safety regulations, including driving beyond legal hours, operating unsafe vehicles, or falsifying logs. These complaints are protected under federal law and can result in significant penalties for carriers.

When to File a Complaint

Knowing when your experience warrants an FMCSA complaint versus other remedies is important. File immediately if you witness:

Dangerous Driving Behavior: Weaving between lanes, excessive speeding, aggressive tailgating, running red lights or stop signs, distracted driving, or showing signs of impairment. Document the date, time, location, license plate, truck number, and carrier name if visible.

Overweight or Unsafe Vehicles: Trucks with visibly overloaded trailers, leaking fluids, bald tires, missing lights, or structural damage that could cause a crash. These violations often indicate systemic safety problems at the carrier level.

Hours-of-Service Violations: If you're a driver being pressured to drive beyond legal limits, or if you have evidence of falsified logs, these complaints receive high priority. Fatigue-related crashes are a leading cause of truck accidents.

Moving Company Fraud: When a moving company holds your belongings hostage, significantly exceeds their binding estimate, damages items through negligent handling, or operates without proper USDOT registration. Learn more about how to avoid moving scams before hiring a carrier.

Gathering Evidence Before Filing

Think of your complaint the way a detective thinks about a case file -- the more specific and verifiable the evidence, the faster it moves from a desk to an active investigation. Here is what to pull together before you sit down to file:

Vehicle Identification: The USDOT number is the most critical piece of information. This number must be displayed on commercial vehicles and uniquely identifies the carrier. Also record the truck's license plate number, trailer number, and any company name or logo visible on the vehicle. If you don't know what a USDOT number is, learn how to identify it on commercial vehicles.

Time and Location Details: Record the exact date, time, and location of the incident. For moving violations, note the road name, direction of travel, mile marker, and nearest intersection. GPS coordinates from your phone are extremely helpful.

Photographic Evidence: Take clear photos or videos of the vehicle, license plates, USDOT numbers, and any safety violations (damaged equipment, leaking materials, unsafe loads). If documenting dangerous driving, do so safely—never use your phone while driving. Pull over or have a passenger record the incident.

Documentation for Moving Complaints: Keep all paperwork including the original estimate, bill of lading, inventory list, delivery receipt, payment records, emails, text messages, and photographs of damaged items. Document everything in writing and keep copies.

Witness Information: If others witnessed the incident, collect their names and contact information. Independent witnesses strengthen your complaint significantly.

Step-by-Step: Filing Online Through the National Consumer Complaint Database

The FMCSA's National Consumer Complaint Database (NCCDB) is the primary system for filing complaints. The process takes 10-15 minutes and creates an official record tied to the carrier's USDOT number.

Step 1: Access the NCCDB Portal. Visit the FMCSA website and navigate to the complaint filing section. The system is available 24/7 and works on desktop and mobile devices. No account creation is required.

Step 2: Identify the Carrier. You can search by USDOT number or company name. USDOT number searches are more accurate because company names may have multiple variations. The system will display carrier details to confirm you've selected the correct company.

Step 3: Describe the Incident. Select from predefined categories like "Unsafe Driving," "Overweight Vehicle," "Moving Fraud," or "Hazmat Violation." Then provide a detailed narrative. Be specific, factual, and chronological. Include what happened, when, where, and why it constitutes a violation.

Step 4: Upload Evidence. Attach all supporting documentation. The system accepts multiple files up to 10MB each. Label files clearly (e.g., "truck_photo_front.jpg" or "original_moving_estimate.pdf").

Step 5: Submit and Track. After submission, you'll receive a confirmation number. Save this number—you'll need it to track your complaint status. FMCSA sends an email confirmation within 24 hours.

Filing by Phone

If you cannot file online or need assistance, call the FMCSA Consumer Hotline at 1-888-368-7238 (1-888-DOT-SAFT). The hotline operates Monday through Friday, 9:00 AM to 5:00 PM Eastern Time.

Phone filing is better when you need help identifying the carrier, have a complex situation requiring explanation, have limited internet access, or are filing immediately after an incident and don't have time to gather all documentation. The representative will guide you through the process and enter information directly into the database.

Have all your evidence ready before calling: USDOT number or carrier name, incident date and location, vehicle identification details, and a clear description of what happened. The call typically takes 15-20 minutes.

Filing a Household Goods Complaint

Moving complaints follow a specialized process because they often involve both federal regulations and consumer protection laws. In addition to filing with FMCSA, you may need to pursue other remedies.

FMCSA Process: File through the NCCDB under "Household Goods" complaint type. Provide your original estimate, final bill, delivery receipt, and documentation of damages or missing items. Include all communication with the mover.

Carrier's Dispute Process: Federal law requires movers to have a dispute resolution process. You must file a claim with the carrier within nine months of delivery. The carrier has 30 days to acknowledge your claim and 120 days to resolve it.

Arbitration: If the carrier doesn't resolve your claim, you can request binding arbitration through FMCSA's approved arbitration program. This is faster and cheaper than court but is binding on both parties.

Small Claims Court: For smaller disputes (typically under $5,000-$10,000 depending on your state), small claims court may be the fastest remedy. You don't need a lawyer and can often recover moving costs, damaged item values, and filing fees.

What Happens After You File

Understanding the investigation process helps set realistic expectations. FMCSA receives thousands of complaints monthly and prioritizes based on safety risk.

Initial Review: Within 5-10 business days, FMCSA reviews your complaint and assigns it a priority level. High-priority complaints (imminent safety threats, hazmat violations, pattern violations) receive immediate attention. Lower-priority complaints may take 30-60 days for initial review.

Investigation Process: FMCSA may conduct a desk audit reviewing the carrier's safety records, schedule a compliance review with an on-site inspection, issue a notice of violation requiring corrective action, or refer the case to state enforcement partners. For serious violations, FMCSA can issue fines ranging from $1,000 to $25,000 per violation.

Your Complaint's Impact: Even if your individual complaint doesn't trigger immediate enforcement, it's added to the carrier's safety record. Multiple complaints create patterns that flag carriers for comprehensive safety audits. This data also affects the carrier's Safety Measurement System (SMS) scores, which can impact their ability to get insurance and contracts.

Timeline Expectations: Simple safety complaints may be resolved in 30-60 days. Complex investigations can take 6-12 months. Household goods complaints typically take 60-90 days for FMCSA review, but your individual claim resolution depends on the carrier's response time and whether you pursue arbitration or legal action.

What FMCSA Can and Cannot Do

This is where we see the most frustration from people who file complaints, so let us be blunt about what the agency can and cannot do on your behalf.

What FMCSA Can Do: Investigate safety violations and issue fines, place carriers out of service for imminent safety hazards, require carriers to take corrective actions, revoke or suspend operating authority, refer criminal violations to federal prosecutors, and publish complaint data that affects carrier safety ratings.

What FMCSA Cannot Do: FMCSA cannot force carriers to refund money or pay damages to individual consumers, act as your attorney in disputes with carriers, guarantee investigation timelines, or intervene in contractual disputes that don't involve regulatory violations. They also cannot pursue complaints against carriers operating solely within one state (intrastate carriers), which fall under state jurisdiction.

For consumer disputes involving money, you must pursue remedies through the carrier's claims process, arbitration, small claims court, or hiring an attorney. FMCSA's role is regulatory enforcement, not consumer dispute resolution.

Other Agencies to Contact

Filing with FMCSA alone is fine, but casting a wider net often produces faster results. Here is how to decide where else to report.

If the carrier only operates within your state (an intrastate-only authority), FMCSA may not have jurisdiction at all. In that case your state DOT's motor carrier division is the right starting point -- and in our experience, state agencies tend to respond faster on local complaints than the federal pipeline does. For defect-related issues (brake failures, tire blowouts, steering problems), the complaint should go to NHTSA rather than FMCSA, since NHTSA handles vehicle safety recalls and defect investigations.

Moving fraud victims should strongly consider filing with their state attorney general's consumer protection division in addition to FMCSA. State AGs have subpoena power and can pursue civil action to recover money on your behalf -- something FMCSA simply cannot do. A Better Business Bureau complaint is worth the five minutes it takes, too. It will not trigger a government investigation, but it creates a public record that shows up when future customers search the company. And if the situation involves outright criminal conduct -- theft, assault, operating under a fake USDOT number -- file a police report. That paper trail is separate from any regulatory action and may be required for an insurance claim down the road.

How to Track Your Complaint

After filing, you can monitor progress using your confirmation number. Log into the NCCDB portal and enter your complaint reference number to view status updates. FMCSA updates complaint status at key milestones: received, under review, investigation initiated, or closed.

You can also call the hotline at 1-888-368-7238 with your confirmation number to speak with a representative about status. Be patient—investigations take time, and FMCSA may not share specific enforcement actions due to confidentiality rules.

If 90 days pass with no update on a high-priority safety complaint, call to follow up. For household goods complaints, focus on pursuing your claim through the carrier's process rather than waiting for FMCSA investigation results.

Protect Yourself: Research Before You Hire

The best complaint is the one you never have to file. Before hiring any trucking or moving company, spend ten minutes doing what we wish everyone did: look the carrier up. Visit our complaint filing guide for additional resources and templates.

On Trucking Record, you can search any carrier by USDOT number or company name and see their crash history, fleet size, and inspection results in plain language. From our own database, carriers with three or more reported crashes in a 24-month window are statistically far more likely to have active complaints against them. If a carrier's record looks rough, that is your cue to keep shopping.

For moving companies specifically, do not skip the basics: confirm they hold a valid USDOT registration, insist on a written binding estimate, read the fine print before you sign, and never hand over full payment until every box is off the truck and accounted for. These steps sound obvious, but the overwhelming majority of moving-fraud complaints we have reviewed involved consumers who skipped at least one of them.

If a violation does happen, take the 20 minutes to file the complaint. We mean it. Your single report might not shut a carrier down on its own, but it becomes part of a pattern that FMCSA investigators rely on when they decide where to focus limited audit resources. One complaint plus four others can be the difference between a dangerous carrier staying on the road and getting pulled off it.
