When a drug charge carries a mandatory minimum, one number can dominate the whole case. A 5-year or 10-year floor binds the judge no matter how low the guideline calculation comes out and no matter how strong the personal mitigation looks. Most defendants hear about two ways below that floor. One is cooperation, which needs the government to file a motion. The other is the safety valve, which does not. Congress wrote it at 18 U.S.C. section 3553(f), and the Sentencing Commission restated it at section 5C1.2 of the Guidelines Manual. Where it fits, the court sets the minimum aside and sentences under the guidelines. Where it does not fit, the floor stays, and every other decision in the case should be made with that knowledge.
The five tests, in plain terms
The statute directs the court to sentence under the guidelines "without regard to any statutory minimum sentence" if the court finds five things at sentencing, after giving the government a chance to be heard. Each test must be met. Losing one loses the valve.
First, limited criminal history. The defendant must not have more than 4 criminal history points, excluding points from 1-point offenses, and must have no prior 3-point offense and no prior 2-point violent offense, all as determined under the guidelines. The three parts of this test are explained below, because the Supreme Court read them strictly.
Second, no violence or weapon. The defendant must not have used violence or credible threats of violence and must not have possessed a firearm or other dangerous weapon, or talked another participant into doing so, in connection with the offense.
Third, no death or serious bodily injury. The offense must not have caused death or serious bodily injury to any person. In drug cases this test often turns on overdose evidence tied to the distributed drug.
Fourth, no leadership role. The defendant must not have been an organizer, leader, manager, or supervisor of others in the offense, as determined under the guidelines, and must not have been engaged in a continuing criminal enterprise.
Fifth, a complete truthful proffer. No later than the time of the sentencing hearing, the defendant must have truthfully told the government all information and evidence known about the offense and any conduct that was part of the same course of conduct or a common scheme or plan. This is the test defendants control most directly, and the one most often litigated. It gets its own section below.
The history test after Pulsifer
The history test caused years of disagreement because of one word: and. The statute lists three conditions joined by and, and courts split over whether a defendant fails the test only by having all three features combined or by having any one of them. In Pulsifer v. United States, 601 U.S. 124 (2024), the Supreme Court adopted the government's reading. A defendant qualifies only if each of the three conditions is satisfied. A prior 3-point offense alone disqualifies, even where the total points stay low and no violent offense exists. The opinion states the rule plainly: eligibility requires the defendant to satisfy each of the three conditions, so failing any one of them closes the valve.
In practice this makes the arithmetic harsh at the edges. The statute bars anyone with "more than 4 criminal history points, excluding any criminal history points resulting from a 1-point offense, as determined under the sentencing guidelines," plus anyone with "a prior 3-point offense, as determined under the sentencing guidelines" or "a prior 2-point violent offense, as determined under the sentencing guidelines." Points come from the guideline criminal history rules, where longer past sentences score more points and old convictions eventually stop counting. A single 3-point offense, which generally reflects a past sentence over a year and a month, ends the inquiry by itself. A 2-point violent offense, meaning a crime of violence as defined in 18 U.S.C. section 16 that is punishable by imprisonment, ends it the same way. Because old convictions can age out of the point count, the record must be scored under the guidelines as of sentencing, not read as a raw rap sheet. Disputes over whether a past case counts, how many points it carries, and whether it is violent are worth litigating, because each answer can decide the whole valve.
What qualifying buys, and what it does not
A defendant who meets all five tests is sentenced under the guidelines without regard to the minimum. Three details shape what that means in numbers.
First, the guideline calculation itself drops. Section 2D1.1(b)(18) gives a 2-level reduction where "the defendant meets the criteria set forth in paragraphs (1)–(5) of subsection (a) of §5C1.2": the instruction is to "decrease by 2 levels." Two levels can move the range meaningfully, and this reduction is part of why counsel pursues the valve even in cases where the minimum might not have bound the sentence anyway.
Second, a floor can remain. Under section 5C1.2(b), for a qualifying defendant whose required minimum was at least five years, "the applicable guideline range shall not be less than 24 to 30 months of imprisonment." The valve removes a 60-month or 120-month floor but replaces it with a 24 to 30 month range floor in these cases. That is still far below the minimum, but it is not probation by default, and advocacy over where inside or above that floor the sentence lands still matters.
Third, the minimum term of supervised release falls with the prison minimum. The commentary provides that a qualifying defendant "is exempt from any otherwise applicable statutory" minimum sentence of imprisonment and minimum term of supervised release. Drug minimums often carry 4, 5, 8, or 10-year supervised release floors, so this exemption shortens the tail of supervision as well as the prison term.
None of this makes the sentence automatic. Once the minimum is set aside, the judge sentences under the guidelines and the factors in 18 U.S.C. section 3553(a), starting with a sentence "sufficient, but not greater than necessary" to serve the purposes of punishment, deterrence, protection of the public, and treatment. The full sequence is described in the federal sentencing overview. The valve opens the bottom of the range. Counsel must still argue for a sentence inside it.
The proffer: tell everything, on time
The fifth test is that the defendant truthfully provides the government all information and evidence the defendant has about the offense and related conduct. The statute does not require a meeting. Preparation decides it. The standard is completeness and truth, and the deadline is fixed: no later than the time of the sentencing hearing. Three rules from the statute govern how to think about it.
The value of the information does not matter. The statute provides that "the fact that the defendant has no relevant or useful other information to provide or that the Government is already aware of the information shall not preclude a determination by the court that the defendant has complied with this requirement." A low-level courier who knows only a first name and a phone number can satisfy this test the same way a well-connected distributor can, if both tell everything truthfully.
Completeness does matter, absolutely. Holding back one fact, minimizing a role, or protecting another person can sink the whole application, because the court must find that the defendant gave all information and evidence known. Memory failures happen, and counsel should prepare the account carefully and correct the record fast if something surfaces later. But a deliberate omission is fatal to the finding, and judges treat late additions with suspicion.
The disclosure carries limited protection. The statute states that information disclosed under this subsection "may not be used to enhance the sentence of the defendant unless the information relates to a violent offense." That shield matters: it lets a defendant admit the full scope of drug conduct without that admission raising the guideline calculation. It has an edge, though. It excepts violent offenses, it addresses use at sentencing rather than every other setting, and it never protects a lie. Go in only with counsel, answer only what is true, and do not freelance.
One more procedural point helps at the hearing. The court must give the government a chance to weigh in, since the finding comes "after the Government has been afforded the opportunity to make a recommendation." Prosecutors sometimes oppose the valve over a disputed weapon fact, a contested role adjustment, or doubts about the proffer's completeness. Counsel should know the government's position before the hearing and arrive with the criminal history scoring, the role evidence, and the proffer record ready to answer it.
Which cases can use it, and which cannot
The valve covers a closed list of offenses: drug trafficking and related offenses under 21 U.S.C. sections 841, 844, 846, 960, and 963, plus maritime drug offenses under 46 U.S.C. sections 70503 and 70506. Congress added the maritime offenses and rewrote the history test in the First Step Act of 2018, and the current text reflects that expansion. Most cases that use the valve are drug trafficking and drug conspiracy cases carrying a 5-year or 10-year minimum tied to weight.
Just as important is what the list leaves out. A consecutive gun count under 18 U.S.C. section 924(c) has no valve; its minimum stacks on top of the drug sentence regardless, and only a cooperation motion can move it. A continuing criminal enterprise prosecution under 21 U.S.C. section 848 is outside the valve by definition, and any defendant who led or supervised others fails the fourth test in any case. Fraud, firearms, immigration, and violent offenses carry their own structures and get no help from this provision. When a case mixes a qualifying drug count with a nonqualifying count, counsel must analyze each count separately rather than assuming one finding covers the sentence.
Two refinements in the guideline commentary often decide close cases. On the weapon test, accountability is personal: the commentary limits the defendant to his own conduct and conduct he aided or abetted, counseled, commanded, induced, procured, or willfully caused. A co-defendant's gun is not automatically the defendant's gun. On the leadership test, the question is whether the defendant faces an aggravating role adjustment under section 3B1.1. Both points are argued on the facts through objections to the presentence report, which carries the probation officer's version of weapon, role, history, and valve eligibility to the judge.
The valve is not cooperation, and the difference matters
The two doors below a minimum look similar and work differently. The cooperation door, 18 U.S.C. section 3553(e), belongs to the government: only on the government's motion may the court go below the minimum to reflect substantial help against another person. The safety valve belongs to the court: the judge makes the finding, and no motion is needed. A defendant who qualifies for the valve needs nothing from the prosecutor. A defendant who does not qualify may need cooperation as the only remaining door, and that help must be real, directed at someone else, and usually early.
The two can combine. A qualifying defendant who also helps others may earn a cooperation motion on top of the valve, and a defendant whose help arrives only after sentencing needs the post-sentencing mechanism described on the Rule 35 page. Counsel's early job is to map which doors are actually open: valve, cooperation, or both, and what each costs in admissions, safety, and timing. No one can promise a motion will be filed, and no one should promise the valve before the record is scored and the facts are tested.
How counsel builds the record
Valve litigation starts at the first meeting, not the month before sentencing. Counsel pulls every prior case and scores criminal history under the guidelines, checking points, dates, and whether any predicate counts as a violent offense. Counsel tests the weapon and violence facts against personal accountability rather than accepting shared blame. Counsel examines role evidence before anyone labels the defendant a manager. And counsel prepares the proffer only after the client understands the completeness standard and the violent-offense edge of the use protection.
Each dispute should reach the judge as a timely written objection to the presentence report, not as a surprise at the hearing. Criminal history scoring, role adjustments, weapon findings, and the valve recommendation all appear in the report, and unchallenged findings tend to stick. Where the government opposes the valve, the hearing is the place to walk through the five tests one by one with the statute and the guideline in hand. The sentencing calculator can help show how a guideline range is built, but it does not decide valve eligibility, so its output never answers whether the floor falls.
What these numbers mean, and what they do not
Every figure on this page is a statutory maximum or minimum or a guideline range, never a prediction. A 10-year minimum can fall to a guideline sentence starting at 24 to 30 months where all five tests are met, or it can stand untouched where one test fails. The facts of a case change everything: the age and weight of old convictions, who possessed a weapon, what role the defendant played, whether anyone was hurt, and whether the proffer was complete and truthful. Those facts, argued through the guideline disputes and the section 3553(a) factors, decide where the sentence lands once the question of the floor is settled.
