How do I respond to an FMCSA enforcement notice?

Chapter 01

What is this letter, and is it a failed audit?

The name printed at the top tells you. A Notice of Claim is how FMCSA starts a case to collect a fine (the rule that defines it). A Notice of Violation lists problems and asks you to correct them, without proposing a fine. A failed new entrant audit notice is something else again. It asks you to prove you fixed things by a deadline, or lose your registration. Each type of notice has its own rules and requires a different response.

Consider this example. Say you run four trucks. Your authority is three years old, so the new entrant audit is long behind you. Last spring, your scores for hours of service went up. FMCSA’s scoring manual lists warning letters and investigations among the steps it takes when scores run high (the scoring manual). In August 2026, a safety investigator got in touch. The investigator reviewed your records remotely. You sent your logs and driver files without meeting in person. The manual calls this an offsite investigation.

Then, on Friday, October 9, 2026, a letter arrives. The top says Notice of Claim. It is dated Monday, October 5.

Where did it come from? The rules say FMCSA can learn of violations “from an investigation, audit, or any other source” (the rule on how cases start). The rules say a full investigation, which they call a compliance review, “may result in the initiation of an enforcement action” (the rule on reviews). In plain words, the review can turn into a case against you. For a carrier in its first 18 months, bad roadside results can also bring an early audit or an investigation. One trigger is three or more inspections in 90 days with half or more ending out of service (the rule on early reviews). So a fine can follow a review of any carrier, new or old. A Notice of Claim therefore needs a separate response, whether or not it followed an audit.

If some roadside inspections behind your scores were simply wrong, use the separate correction process: how to dispute a violation in DataQs. That fixes the record. It does not answer this notice.

Other letters look alike, so check the name. A Notice of Violation lists what FMCSA thinks is wrong and what it wants done. It also says how to tell FMCSA that you fixed the problem, or that you disagree (the rule on notices). It asks for no money. But if the problem is not fixed to FMCSA’s satisfaction, a formal case can follow. And FMCSA does not have to send a Notice of Violation first.

People search for “DOT audit fines”, but a failed new entrant audit works differently. That notice gives most carriers 60 days to prove they fixed things. If they do not, the registration is revoked and the trucks are put out of service (the rule on a failed audit). The notice does not propose a fine. That process is explained in what happens if you fail the audit, and the whole audit is in our guide to the new entrant safety audit. Your letter says Notice of Claim. So yours is an enforcement case: a case to make you pay a fine.

Chapter 02

What am I accused of, and what can it cost?

The notice must spell it out. It must state the facts, the rules FMCSA says you broke, the fine it proposes and the most the law allows. It must also say how and when you can pay, contest or otherwise settle it (the rule on what a notice must contain). Each violation is a separate numbered charge. As of September 2026, most safety violations can cost up to $19,246 each. Failure to keep required records can cost $1,584 a day, up to $15,846 (FMCSA’s penalty table).

Your notice lists three charges. Charges 1 and 2 say you let a driver drive more hours than the rules allow, on two different days. Charge 3 says a driver’s file was missing papers the rules require. Next to each charge is the rule it cites and an amount. Say the total comes to $7,300. We made that number up for this story. The amount in your notice depends on the facts of your case.

Next, check the maximum allowed for each charge. The penalty table groups violations by type (FMCSA’s penalty table). Breaking a safety rule, like the hours limit, can cost up to $19,246 for each violation. Failing to keep a required record, like a complete driver file, costs up to $1,584 a day. The total for one charge stops at $15,846. The combined maximum for the three charges in this example is $54,338. The notice must print the maximum too, so you can compare.

A few other lines in the same table matter to small fleets. Knowingly faking a record to hide another violation, like a false log, can cost up to $15,846. Running without the insurance the rules require can cost up to $21,114, and each day counts as a new violation. And if a driver goes more than 3 hours past the driving limit, the table calls it egregious. Then FMCSA treats it as serious enough for the full maximum. People often call all of these DOT violation fines.

These amounts rise with inflation. The ones on this page come from the update the Department of Transportation published on December 30, 2024 (the 2025 update). For example, it raised the $18,759 cap to $19,246. The law expects an update every January, but we found none for 2026 as of September 21, 2026. Each update covers only violations that happen after it takes effect. So the amounts in force on the day of the violation are the ones that count.

How does FMCSA pick a number under the cap? The rules list what it weighs. It looks at “the nature, gravity of the violation” and how much you were to blame. It also looks at your “history of prior offenses” and the “effect on ability to continue to do business” (the rule on fine amounts). The law adds that each FMCSA civil penalty must be “calculated to induce further compliance” (the federal law). In plain words, the fine is meant to make you follow the rules from now on.

Since May 27, 2026, you can also see how the number was worked out. New Department of Transportation rules took effect that day (the April 2026 rules). They say a proposed fine must come in writing “along with a full explanation of the basis for the calculation” (the rule on fines). The agency must also share its worksheets and charts. And the fine should reflect “any mitigating factors (such as whether the violator is a small business)”. A mitigating factor is a reason to make the fine smaller. If your notice does not show the math, ask for it.

Chapter 03

How long do I have, and what if I do nothing?

You have 30 days to reply in writing (the rule on replies). The 30 days count from the day the notice was served. For a notice sent by mail, that is the mailing date shown on it, not the day you opened it (the rule on service). If you do nothing, FMCSA can issue a Notice of Default and Final Order. The proposed fine becomes final 5 days after that order is served, and you are treated as admitting every charge.

Back to your notice. It comes with a certificate of service, a page that says when and how it was sent. Yours says it was mailed on Monday, October 5. So day 30 is Wednesday, November 4. The four days it spent in the mail are already gone.

The rules on counting days add two things (the rule on counting time). When a notice comes by mail, 5 days are added, which would move you to Monday, November 9. And a deadline that falls on a weekend or a federal holiday moves to the next working day. But plan on November 4. That way, no argument about counting can hurt you.

A phone call does not replace a written reply. Say you call FMCSA to ask about a deal. The rules give you 30 days to reply, even while you are negotiating. So whatever you choose, put your reply in writing and get it in on time. It goes to the FMCSA Service Center named in the notice. That is the FMCSA office handling your case.

Now say you put the letter in a drawer instead. After day 30, FMCSA can declare you in default. Its order makes the Notice of Claim, with the full proposed fine, the final order in your case. That order takes effect 5 days after it is served (the rule on replies). The rule says a default “constitutes an admission of all facts alleged” in the notice. In plain words, silence counts as saying yes to every charge.

The final order also sets a payment deadline. If FMCSA has not been paid 45 days after that date, it sends a warning by certified mail or express service. If it is still unpaid 90 days after that date, you must stop running interstate on day 91. A for-hire carrier’s registration is suspended too (the rule on unpaid fines and the rule on registration). The only ways to stop that are proof you paid in full, or proof you filed for Chapter 11 bankruptcy. Running anyway can cost up to $19,246 for each day (FMCSA’s table for broken orders). And once the order is final, an unpaid fine also accrues interest, extra penalties and fees (the rule on paying).

If you missed the deadline, act at once. You have 20 days after a final order is served to ask FMCSA to look again. After a default, it looks only at whether you really defaulted. It can cancel the order if you show “excusable neglect, a meritorious defense, or due diligence in seeking relief” (the rule on a second look). In plain words, you need a good reason for missing it, a real defense to the charges, or proof you moved fast.

Some owners think about closing the company and starting over with a new DOT number. The rules call that a reincarnated carrier (the rule on reincarnated carriers). If the new company was set up to “avoid paying a civil penalty”, FMCSA can suspend or revoke its registration. The same goes if it was set up to “avoid responding to an enforcement action”. Respond to the notice instead of trying to avoid the case.

Chapter 04

Should I fix it, pay it, settle it or fight it?

The rules give you four ways to answer (the rule on replies, the rule on settlements). You can pay in full, settle, ask for binding arbitration, or contest the charges. Fixing the problem is not a fifth choice. You do it whichever way you go. Paying admits every charge. Settling is a signed deal that can lower the fine or spread the payments. In arbitration, you admit the charges and argue only about the amount. Contesting means you answer each charge and ask for a decision.

Begin by correcting the violations, whatever response you choose. The week the notice arrives, you change how you plan loads, so no driver leaves without enough hours left. You check each driver’s hours in the ELD every week. You finish the driver file, using our list of the records to keep. And you keep a dated copy of every change.

Will correcting the violations lower the fine? No rule promises that. Nothing in the rules says a fix cancels a Notice of Claim or takes a set amount off. The correction can still support your response. When you contest, your reply must list “factors in mitigation of the claim” (the rule’s definitions). Those are reasons the fine should be smaller, and your fix can be one of them. The rules on fine amounts count your “history of prior offenses” (the rule on fine amounts). So a problem that comes back can make the next fine bigger. A settlement may also include “conditions, actions, or provisions” to fix the violations (the rule on settlements). With a Notice of Violation, the fix is the answer itself. You tell FMCSA what you fixed, and show it.

The first option is full payment. You pay within the 30 days, and you need not write a reply. But the rule says payment is “an admission of liability” for every fact in the notice, unless FMCSA agrees in writing that it is not. You also give up the right to contest, and the notice becomes the final order (the rule on paying). It ends the case, with every charge admitted.

The second option is a settlement. The rules allow negotiations. If both sides reach a deal, they sign a settlement agreement (the rule on settlements). It must state the amount claimed, the amount you pay, and when and how you pay. It may hold part of the fine “in abeyance”. That means it is set aside, and you do not pay it unless you break the deal. If you break it, you can lose the reduction, and “the original amount asserted will be due immediately”. The signed deal becomes the final order. FMCSA may also let you pay in parts. But miss one payment, and the plan is void and the whole debt is due at once (the rule on unpaid fines). If it is still unpaid 90 days after the missed payment, the stop on day 91 applies to you too.

Here is how that could go for you. On Monday, October 26, you write to the Service Center named in the notice. You say you want to settle. You list what you fixed and attach dated copies. And you ask how the $7,300 was worked out. Say that on Monday, November 2, you both sign a deal. You pay $4,000 in four monthly payments. Another $1,500 is held in abeyance. And you agree to send proof of your weekly hours checks for six months. These numbers are made up too. We cannot tell you what FMCSA will agree to in your case. We found no published rule on how much it takes off (the rule on settlements).

The third option is binding arbitration, under FMCSA’s own program. You must admit that the violations happened. Then only the amount is argued (the rule on replies). The rule names the program, but we could not find its details.

The fourth option is to contest the charges. You write a reply that admits or denies each numbered charge. Any charge you do not clearly deny counts as admitted. A general “we deny everything” is not enough, and it can lead to a default. You must also list every defense you know of. Then choose how the case will be heard (the rule on replies). You can send written evidence with no hearing, or ask for an informal or a formal hearing. That choice is binding. A deal is still possible later, at any time before a final order (the rule on settlements). After the reply, the case follows legal steps with deadlines for both sides. If you contest the charges, talk to a lawyer who handles FMCSA cases.

What has changed lately? The caps rose on December 30, 2024, so older articles quote lower numbers (the 2025 update). And since May 27, 2026, the proposed fine must include an explanation of the calculation (the April 2026 rules). There are also things we could not check. FMCSA has pages on how it works out fines, including one on its Uniform Fine Assessment. Its website blocks our tools, so we could not read them. We also found no official numbers on how often cases settle, or for how much. Start by identifying the notice, noting when your 30 days to reply end and preparing your response.
