An unpaid civil penalty is the quietest way to lose operating authority. There is no insurer cancelling a filing and no roadside inspector — just a Notice of Claim that went unanswered, a payment date that passed, and a sanction that FMCSA is required to impose once the calendar runs out. The good news is that the cure is the most mechanical one in the whole reinstatement catalogue: pay, prove it, file the $80 request. This guide covers how the sanction happens, every option you have before it does, how to pay, and what the reinstatement needs afterward. For the survey of every revocation cause, see common reasons for DOT revocation.
How Does an Unpaid Penalty Turn Into a Revoked Authority?
The statute is 49 U.S.C. 13905(d)(2)(B): FMCSA may “withhold, suspend, amend, or revoke any part of the registration” of a carrier, broker, or freight forwarder that fails to pay a civil penalty, or fails to “arrange and abide by an acceptable payment plan” for it, within 90 days of the payment date in the agency's order. FMCSA wrote two rules to carry that out. 49 CFR 386.83 prohibits any CMV owner or operator that has not paid in full within 90 days from operating in interstate commerce “starting on the next (i.e., the 91st) day” until FMCSA “has received full payment.” 49 CFR 386.84 suspends the registration of a for-hire carrier, broker, or freight forwarder on the same 91st day, again until full payment — and adds that a registrant that keeps operating while suspended “may be revoked after an additional notice and opportunity for a proceeding.”
So the honest label is “suspended, and revoked if you keep rolling.” Either way the SAFER record stops saying AUTHORIZED, the L&I Authority History records the action, and the docket does not come back on its own. Here is the whole timeline:
| Step | Rule | Clock | What you can still do |
|---|---|---|---|
| Notice of Claim (NOC) served | 49 CFR 386.14 | Reply within 30 days of service | Pay in full, contest (written evidence, informal or formal hearing), or request binding arbitration on the amount |
| No reply | 49 CFR 386.14 default | Notice of Default and Final Order; effective 5 days after service | Petition to vacate only for excusable neglect, a meritorious defense, and due diligence |
| Final agency order sets a payment date | Settlement (49 CFR 386.22) or decision | Day 0 | Pay, or get an installment plan accepted and in writing |
| Warning notice | 49 CFR 386.83(b) / 386.84(b) | About day 45 | Show cause: proof of full payment, or proof of a chapter 11 filing |
| Sanction | 49 CFR 386.83(a) / 386.84(a) | Day 91 | Interstate operation prohibited; registration suspended until full payment |
| Operating anyway | 49 CFR 386.84 | After additional notice | Registration may be revoked; new penalties on top of the old debt |
What Are My Options Before Day 91?
- Pay in full.The only option that ends the case with nothing left hanging. FMCSA's enforcement page treats a case as closed once the penalty is paid, a settlement is signed, or the respondent defaults into a final order.
- Contest it inside the 30-day reply window. Under 49 CFR 386.14 you can admit or deny each allegation, raise defenses, and choose written submissions, an informal hearing, or a formal hearing. Miss the window and the default order settles the question for you.
- Settle. 49 CFR 386.22 allows a settlement agreement, and settlements commonly carry a payment schedule. A settlement is a final order too, so its dates start the same 90-day clock.
- Ask for an installment plan.The statute contemplates “an acceptable payment plan,” and both sanction rules describe what happens under one. Request it from the FMCSA service center named on the NOC and get it in writing. Miss a single installment and the plan is void, the entire balance is due at once, and the sanction lands 91 days after the missed payment.
- Do not count on an appeal to buy time.Both rules say an appeal to a federal court of appeals does not stay the payment date “unless the Court so directs.” The only carve-out written into the rules is a chapter 11 bankruptcy filing.
How Do I Pay an FMCSA Civil Penalty?
By debit or credit card through FMCSA's online fine payment portal, linked from the agency's Fine Payments page, using the case number and docket number printed on the NOC or final order. Two details matter. FMCSA stopped accepting checks and money orders for every transaction — civil penalties included — on September 30, 2025, and says paper payments received after that date “will not be processed and will be returned,” which is a fine way to sail past day 90 without meaning to. And the sanction ends when FMCSA has received full payment, so save the confirmation page and note the date; if the sanction letter and your payment cross in the system, that receipt is what clears it up.
After Payment: The $80 Reinstatement
Full payment lifts the operating prohibition and the suspension by the rules' own terms, but the docket is restored through the reinstatement request — $80 under 49 CFR 360.3T(f)(52), filed in Motus with a Login.gov sign-in or on Form MCSA-5889. FMCSA's reinstatement FAQ sets the preconditions: insurance and a BOC-3 on file, and an active USDOT number with current MCS-150 data, because “our systems will not allow users to request reinstatement if the USDOT Number is Inactive or Out of Service.” If the shutdown ran long enough for the biennial to lapse, that update goes first. Once the request is complete FMCSA says authority is “typically active within a week of application receipt and valid payment”; complete filings we handle usually show ACTIVE within about 48 hours. The $80 is not refunded if the request bounces, so confirm the payment posted and the insurance and BOC-3 show on L&I before you submit. Keep the payment confirmation, the case number, and the docket number together — that packet is what a reinstatement with a penalty in the history rests on.
What If I Cannot Pay It All at Once?
Ask for the plan early, not on day 85. 49 U.S.C. 13905(d)(2)(B)(ii) ties the plan to the same 90-day window as the payment itself, and the sanction rules only recognize a plan FMCSA has actually accepted. Once you are on one, treat the installment dates like tax deadlines: a missed installment does not just add a late fee, it voids the plan and starts the 91-day countdown on the whole remaining balance. If the business is in a chapter 11 case, tell FMCSA — both 386.83 and 386.84 carve out chapter 11 debtors, and the show-cause notice accepts proof of the filing.
Does the Penalty Go Away If I Get a New MC Number?
No, and trying is expensive. The debt attaches to the company, not the docket. Section 13905(d)(2)(B) lets FMCSA withhold a new registration for an unpaid penalty just as it lets the agency suspend an existing one, and 49 CFR 386.83 bars the owner or operator from interstate commerce regardless of which number is on the door. You would pay $300 for an application FMCSA can hold, restart the new-entrant period, and still owe the penalty. The comparison in reinstatement vs new authority is lopsided in every case; here it is not even a contest. Pay it, prove it, reinstate.
