What Is a Federal Petty Offense? Penalties and Procedure

A federal petty offense is the lowest tier of crime in the federal system: a Class B misdemeanor, a Class C misdemeanor, or an infraction, with a maximum of six months in jail and a fine capped at $5,000 for an individual.¹ Most people meet these charges as ticket-like violations on federal land — speeding through a national park, an off-leash dog on a federal trail, a stop sign run on a military base. The name sounds minor, and the penalties usually are, but a conviction is still a federal criminal conviction and goes on your record.

How Federal Law Defines It

The classification turns on the maximum punishment the statute authorizes, not on what a judge actually imposes. The tiers work like this:²

Class B misdemeanor — more than 30 days but no more than six months of possible jail time.
Class C misdemeanor — more than five days but no more than 30 days.
Infraction — five days or less, or no jail time authorized.

An offense only qualifies as “petty” if the maximum fine also stays within $5,000 for an individual or $10,000 for an organization.¹ Anything with a ceiling higher than six months in jail is a Class A misdemeanor or a felony, which carries stronger procedural rights, including a jury trial and appointed counsel. The six-month line is the boundary that separates the two worlds.

What People Actually Get Charged With

Most federal petty offenses are regulatory violations that happen on federally managed land: national parks, national forests, military installations, and federal buildings. Traffic tickets make up a big share. Speeding on a park road, rolling a stop sign on base, parking illegally at a federal courthouse — because the pavement is federal, federal law applies rather than the state code.

Outdoor recreation rules account for much of the rest. Fishing without the required permit, camping outside a designated site, lighting a campfire during a burn ban, entering a closed wildlife area, or walking a dog off-leash where leash rules apply are all common charges. The pattern is regulatory: specific rules on specific land, not conduct that is inherently dangerous.

Maximum Penalties

Jail

The ceiling depends on the sub-category. A Class B misdemeanor can carry up to six months, a Class C up to 30 days, and an infraction up to five days.² Jail is uncommon in practice; judges usually impose fines. The authority exists, though, and repeat violators or cases involving actual harm see it used more often.

Fines

The standard maximum fine is $5,000 for an individual and $10,000 for an organization, across all three petty categories. There is one exception worth flagging: if you profited from the offense or someone else lost money because of it, the fine can be set at up to twice the gross gain or twice the gross loss, whichever is greater.³ That can push a fine past $5,000 in cases involving unauthorized commercial activity on federal land.

Special Assessment

Every federal conviction, including a petty one, carries a mandatory special assessment on top of the fine: $5 for an infraction or Class C misdemeanor, $10 for a Class B misdemeanor. The obligation expires five years after judgment if it remains unpaid.⁴

Probation

A judge can order probation instead of, or alongside, jail and a fine. The maximum probation term is five years for a Class B or C misdemeanor and one year for an infraction.⁵ Probation carries conditions such as reporting requirements and geographic limits, and violating them can lead to revocation and resentencing.

No Jury Trial

The biggest procedural difference between a petty offense and a more serious charge is who decides guilt. The Supreme Court set the rule in Baldwin v. New York: when the maximum authorized imprisonment is six months or less, the offense is presumptively petty for Sixth Amendment purposes and the defendant has no constitutional right to a jury.⁶ A judge decides the case in a bench trial.

How the Case Moves

The Violation Notice

A case usually begins when a federal officer — a park ranger, federal police officer, or military police — hands you a violation notice. It looks and works much like a traffic ticket, describing the alleged violation, citing the regulation, and telling you what to do next.

Paying Without Appearing

For many minor violations, the notice lists a fixed dollar amount you can pay to close the case without going to court. This is called collateral forfeiture. You send the money, the case ends, and no hearing takes place.⁷ Payment usually runs through the Central Violations Bureau, the federal judiciary’s central processing office.⁸ One thing to know before you pay: forfeiture resolves the charge but may be treated as a conviction for some purposes, depending on the district and the offense.

Going to Court

If the notice requires an appearance, or you want to contest the charge, the case goes before a U.S. Magistrate Judge. For petty offenses, the magistrate handles the whole case — arraignment, plea, trial, and sentencing — and does not need your consent to do so. That is different from other misdemeanors, where you can insist on a district judge.⁷

At arraignment the judge tells you the charge and takes your plea: guilty, not guilty, or, with the judge’s permission, no contest. A not-guilty plea leads to a bench trial. If the judge finds you guilty, or you plead guilty, sentencing usually happens the same day within the statutory ceilings above.

Appealing

If a magistrate judge convicts you, you can appeal to a district judge by filing a notice of appeal within 14 days of the judgment.⁷ It is not a retrial. The district judge reviews the magistrate’s proceedings for legal error. If you cannot afford a copy of the trial record, the court must provide one at government expense.

Whether You Get a Free Lawyer

For petty offenses, there is no automatic right to court-appointed counsel. The Criminal Justice Act guarantees a free lawyer for anyone facing a felony or Class A misdemeanor who cannot afford one, but Class B misdemeanors, Class C misdemeanors, and infractions fall outside that guarantee.⁹ A magistrate judge may appoint counsel when the interests of justice require it, but that is discretion, not a right.

You can always hire a private attorney. If jail time is a realistic possibility on your charge, doing so is worth serious consideration. If you cannot afford one and think your situation warrants appointed counsel — real risk of incarceration, unusually complex facts — you can ask the judge to exercise that discretion, without counting on the answer being yes.

What a Conviction Means Afterward

A petty offense conviction is still a federal criminal conviction. It goes on your record and can turn up on background checks. For most people in most situations, a single ticket for something like park speeding will have limited long-term effect. It is not nothing, though, and it does not simply disappear.

For noncitizens, the stakes can run higher. Federal immigration law makes a person inadmissible for a conviction involving moral turpitude, but the statute contains what is literally called a “petty offense exception”: the moral turpitude ground does not apply if the maximum possible penalty was no more than one year of imprisonment and the actual sentence was no more than six months, provided you have only one such conviction.¹⁰ Because the maximum for any federal petty offense is six months, most will fall inside that exception. Immigration consequences are fact-specific, though, and anyone with an immigration concern should talk to an immigration attorney before resolving even a trivial-looking federal charge.
