Felonies, Misdemeanors, and Infractions: Legal Distinctions

The United States criminal justice system divides offenses into three foundational tiers — felonies, misdemeanors, and infractions — each carrying distinct procedural rights, penalties, and collateral consequences. These classifications shape every stage of a case, from the arrest process through sentencing and beyond. Understanding where an offense falls within this hierarchy determines what constitutional protections attach, how prosecutors charge the conduct, and what long-term burdens a conviction imposes.

Definition and scope

Offense classification in U.S. law operates along a spectrum of severity, with each tier defined primarily by the maximum authorized punishment. The federal system codifies this structure across Title 18 of the United States Code, while the Model Penal Code — published by the American Law Institute — provides the influential framework that most state legislatures have adapted into their own statutory schemes.

Felonies are the most serious category. Under federal law (18 U.S.C. § 3559), a felony is any offense punishable by more than one year of imprisonment. Federal felonies are further subdivided into five classes (A through E), with Class A felonies carrying a maximum life sentence or death, and Class E felonies carrying a maximum of five years.

Misdemeanors are less serious offenses punishable by up to one year of incarceration, typically served in a county jail rather than a state or federal prison. Federal misdemeanors are classified into three classes (A, B, and C) under the same statute, with Class A misdemeanors carrying up to one year and Class C misdemeanors carrying no more than 30 days.

Infractions (sometimes called violations or petty offenses) sit below misdemeanors on the severity scale. They are generally punishable by fine only, with no possibility of incarceration. The federal definition at 18 U.S.C. § 19 defines a petty offense as a Class B or C misdemeanor or an infraction with a fine of no more than $5,000 for individuals.

How it works

Offense classification is not static — it flows from the charging instrument and is subject to prosecutorial discretion, statutory alternatives, and judicial findings. The mechanism operates through the following stages:

1. Legislative definition. Legislatures assign a maximum penalty to each offense when drafting the underlying statute, which determines the default classification. For example, a drug possession charge may be graded as a felony or misdemeanor depending on the controlled substance and quantity under the Controlled Substances Act (21 U.S.C. § 801 et seq.).

2. Prosecutorial charging. A prosecutor selects specific charges from available statutes based on the facts and evidence gathered. In some states, a single act may support both felony and misdemeanor charges, giving prosecutors flexibility. Plea bargaining frequently results in felony charges being reduced to misdemeanors in exchange for a guilty plea.

3. Grand jury or preliminary hearing. For federal felonies, the Fifth Amendment requires indictment by a grand jury before trial. Misdemeanors and infractions typically bypass this requirement entirely.

4. Arraignment and plea. At the arraignment, the defendant is formally notified of the charge tier, which dictates whether appointed counsel is constitutionally required and what bail procedures apply.

5. Conviction and sentencing. Conviction on a felony triggers the broadest set of collateral consequences: loss of voting rights in most states, firearm disqualification under 18 U.S.C. § 922(g), ineligibility for federal benefits, and immigration consequences including deportation for non-citizens.

A critical procedural distinction: the Sixth Amendment right to a jury trial, as interpreted in Baldwin v. New York (1970) and Blanton v. City of North Las Vegas (1989), attaches only when the offense carries a potential sentence exceeding six months. Infractions and Class B/C misdemeanors generally fall below this threshold.

Common scenarios

Practical application of these classifications appears across the most frequently prosecuted offense categories:

• DUI/DWI. A first-offense DUI is typically charged as a misdemeanor in most states. A subsequent offense, or one involving injury or a minor passenger, commonly elevates to a felony under state aggravated DUI statutes.

• Drug offenses. Simple possession of a small quantity of marijuana may be classified as a civil infraction in states that have decriminalized it. Possession with intent to distribute, particularly for Schedule I or II substances under the Controlled Substances Act, is a federal felony carrying mandatory minimum sentences under 21 U.S.C. § 841. The full spectrum of drug offense classifications depends heavily on substance type, quantity, and jurisdiction.

• Assault. Simple assault — unwanted physical contact without serious injury — is frequently charged as a Class A misdemeanor. Aggravated assault involving a weapon or serious bodily harm becomes a felony, with violent crime charges carrying penalties ranging from two years to decades of incarceration.

• Traffic violations. Standard speeding citations are infractions in every U.S. jurisdiction, carrying fines but no criminal record. Reckless driving is elevated to a misdemeanor in most states; vehicular manslaughter is a felony.

• Theft offenses. The felony/misdemeanor line for theft is drawn by dollar threshold, which varies by state. A theft valued below $500 is typically a misdemeanor petty theft; above a statutory threshold (commonly $1,000 under state penal codes), it becomes felony grand theft.

Decision boundaries

Determining the classification of a specific charge requires examining overlapping factors rather than any single element:

Felony vs. misdemeanor — key differentiators:

Wobbler statutes represent a formal decision boundary in states including California (Penal Code § 17(b)) and Texas. A wobbler is an offense that can be charged as either a felony or a misdemeanor, with the classification determined by prosecutorial discretion at filing or judicial discretion at sentencing. If a court sentences a wobbler offense as a misdemeanor, the conviction is legally treated as a misdemeanor for all purposes.

Enhancement provisions shift classification upward. A misdemeanor domestic battery charge may elevate to a felony upon a prior conviction under state recidivist statutes. Federal sentencing guidelines at U.S.S.G. § 4B1.1 treat defendants with prior felony convictions as career offenders, substantially increasing guideline ranges regardless of the current offense's base classification.

Juvenile adjudications operate outside this framework. Under the Juvenile Justice and Delinquency Prevention Act (34 U.S.C. § 11101 et seq.), adjudications of delinquency are not criminal convictions and do not carry the same collateral consequences, though transfer to adult court for serious offenses can result in felony prosecution. The juvenile criminal defense framework applies distinct procedural standards.

Post-conviction, the tier of the original offense controls eligibility for expungement or record sealing. Infractions are routinely sealable in jurisdictions that provide the mechanism; felony expungement is available in fewer than 30 states, and federal felonies have no general expungement statute as of the date of this publication.
