How to report a DOT violation without putting your job at risk
Sometimes the violation isn't yours: a dispatcher pushing you past your hours, a shipper threatening to pull your freight, a broker working under someone else's name. Here is where each one goes, what makes a complaint stick, and how the law protects you.

Reporting a DOT violation in numbers
To report a DOT violation, file a complaint with FMCSA's Complaint Center online or by phone, naming the company by USDOT number and describing what happened, when, and where. A driver pressured to break safety rules has 90 days to file a coercion complaint, and 180 days to report retaliation to OSHA.
Most of what we write about DOT violations covers the ones written against you. This guide is about the other kind: the violation someone else commits, or wants you to commit.
I spent more than six years in risk management before I founded Simplex, and I have led it for more than 25 years since. Reporting feels risky for a driver or a small carrier, which is why the rules come with deadlines, confidentiality, and protection against retaliation. Those protections only work if you file the right complaint, in the right place, on time.
If you received a violation at a roadside inspection, our guide to recovering from a DOT violation covers what happens next.

Key takeaways
Emergencies go to 911, not FMCSA
The FMCSA Complaint Center handles past events. Report a truck that is a danger on the road right now to 911 or local police.
Identify the company by USDOT number
FMCSA says details like the date, time, location, USDOT number, and photos make a complaint much more likely to be verified and acted on.
Coercion requires that you spoke up
It counts only if you told the carrier, shipper, receiver, or broker the trip would break a rule, and they threatened or punished you for refusing.
90 days for FMCSA, 180 for OSHA
Coercion, ELD harassment, and substantial-violation complaints go to FMCSA within 90 days. Retaliation complaints go to OSHA within 180 days.
Your name is protected, within limits
FMCSA discloses a complainant's identity only when it is needed to prosecute a violation. Coercion and harassment cases usually need it.
Complaints against you stay on file
FMCSA keeps each complaint in the company's permanent record and uses complaints to help decide which companies to investigate.

How do you report a DOT violation?
You report a DOT violation to FMCSA through the FMCSA Complaint Center, formerly the National Consumer Complaint Database, online or through its hotline. It handles events that already happened. If a truck is a danger on the road right now, call 911 or local police, because on-road traffic enforcement belongs to state and local law enforcement.
FMCSA uses complaints, along with other data, to decide which companies to investigate. After review, it tells you whether your complaint is actionable: by email if you give an address, by mail if you don't.
| What happened | Where to report it | Deadline |
|---|---|---|
| A truck speeding, driving recklessly, or leaking cargo right now | 911 or state or local police | Immediately |
| A carrier running unsafe equipment, or operating without authority or insurance | FMCSA Complaint Center | 90 days if it could cause serious injury or death |
| A carrier, shipper, receiver, or broker pressuring you to break a safety rule | FMCSA Complaint Center, as coercion | 90 days |
| A carrier using your ELD data to push you past your hours or to drive ill or fatigued | FMCSA Complaint Center, as harassment | 90 days |
| Firing, discipline, or lost pay for reporting or for refusing an unsafe trip | OSHA, as an STAA whistleblower complaint | 180 days |
The Complaint Center also takes complaints against property brokers, ELD providers, drug and alcohol service agents, and training providers, plus registration fraud and identity theft. For load-board scams and double brokering, see our guide to freight fraud.
How to file a DOT violation report FMCSA can act on
A complaint FMCSA can act on names the company, the rule, and the facts. If a complaint is vague and FMCSA can't reach you for details, it may be judged non-actionable.
Step 1: Write it down the same day
Record the date, time, location, who said or did what, and the road and traffic conditions. If you aren't sure of the date, give your best estimate and say so.
Step 2: Identify the company
Search for the company by name or USDOT number in the complaint form. If it doesn't come up, you can enter its details by hand.
Step 3: Name the rule
Under 49 CFR 386.12, a written complaint of a substantial violation, coercion, or harassment must be signed, name the regulations involved, and state the facts and date of each allegation. For coercion, that is the rule you were pushed to break, such as hours of service.
Step 4: Attach the evidence
Upload photos, videos, texts, emails, load confirmations, or ELD records. The form takes common document, image, and video formats, up to 2 GB per file.
Step 5: Choose what the company sees, then save your case number
The form asks whether to share the allegation only, or the allegation and your contact information, with the company. Print or save the complaint before you submit, and keep the case number it gives you.
What if a carrier, shipper, or broker pressures you to break the rules?
That is coercion, and it is prohibited. Under 49 CFR 390.6, motor carriers, shippers, receivers, and transportation intermediaries such as brokers, including their agents, may not coerce a driver to operate in violation of the safety rules, hours of service included. Carriers also may not coerce a driver to break FMCSA's commercial regulations.
49 CFR 390.5T defines it narrowly: a threat to withhold business, work, or employment, or to take adverse action, to make you drive under conditions you said would break a rule. Actually withholding work or punishing you for refusing counts too.
When does ELD monitoring become harassment?
Under 49 CFR 390.36, a carrier harasses a driver when it uses ELD information in a way it knew, or should have known, would make the driver break the hours-of-service rules or drive while ill or fatigued. It covers independent contractors driving for the carrier. Monitoring productivity is allowed, as long as it doesn't cross that line.
For how the hours rules and the device fit together, see ELDs and hours of service.
What does FMCSA do with the complaint?
Both complaints must be filed in writing, and signed, within 90 days of the event. If FMCSA finds a complaint complete and non-frivolous, it investigates and tells you the findings. If not, it dismisses it and tells you why in writing.
Coercion and harassment violate the safety regulations in Part 390. FMCSA's penalty schedule allows up to $19,246 per violation of Parts 390 through 399, and for ELD harassment, FMCSA may seek the maximum the law permits.
Are you protected if you report a DOT violation?
Yes, in two ways: FMCSA limits who learns your name, and federal law bars retaliation. FMCSA does not disclose a complainant's identity unless it is needed to prosecute the violation, and then it must take every practical step to protect you from harassment, discipline, or financial loss.
Coercion and harassment cases do require naming the driver. That is where the second protection comes in.
What does the STAA whistleblower law cover?
The Surface Transportation Assistance Act, 49 U.S.C. 31105, bars firing, disciplining, or discriminating against a driver on pay or terms because the driver:
- Filed a complaint about a commercial motor vehicle safety or security violation, or was believed to be about to
- Refused to drive because the trip would break a safety rule, or out of a reasonable fear of serious injury from the vehicle's condition
- Reported hours on duty accurately
- Cooperated with a safety investigation, or gave the authorities facts about a crash
The law covers independent contractors while they personally drive a commercial motor vehicle, so owner-operators leased to a carrier are included. A refusal over the vehicle's condition is protected only if you first asked the employer to fix it and it wasn't fixed.
How do you file a retaliation complaint?
File with OSHA within 180 days of the retaliation: online, which OSHA prefers, or by phone, mail, fax, email, or in person at a local OSHA office. OSHA has 60 days to investigate and issue findings. Remedies can include reinstatement, back pay with interest, attorney fees, and punitive damages of up to $250,000.
Which DOT violations do you have to report yourself?
Convictions, license actions, roadside reports, and certain test results. These reports aren't optional, and each has its own deadline.
| Who reports to whom | What | Deadline |
|---|---|---|
| Driver to employer | A traffic conviction in any vehicle, except parking | Within 30 days, in writing |
| Driver to employer | A license suspension, revocation, or CDL disqualification | Before the end of the next business day |
| Driver to carrier | The roadside inspection report | At the next terminal, or right away if not due at one within 24 hours |
| Employer to the Clearinghouse | Alcohol results of 0.04 or higher, refusals to test, and other listed results | By the close of the third business day |
The conviction and suspension rules are in 49 CFR 383.31 and 383.33. The employer's reporting list is in 49 CFR 382.705, and our Clearinghouse guide covers queries and registration.
What happens when someone reports your company?
The complaint goes into your company's file at FMCSA as part of its permanent record, and FMCSA uses complaints, with other data, to decide which companies to investigate. A detailed complaint or a pattern of unsafe behavior can lead to an investigation or a referral to a field office, and urgent cases can be expedited.
An investigation looks at far more than the complaint. Our guide to DOT compliance audits covers what investigators review.
The best protection is a written policy: dispatch never asks a driver to run past the hours rules, a refusal is logged and respected, and ELD data is used to plan trips, not to push drivers. Our DOT safety compliance team can help you put that policy and the records behind it in place.
