Three strikes laws punish repeat offenders with long mandatory sentences, often 25 years to life, after a third qualifying felony conviction.
The catch is that not every felony counts as a strike. Each state and the federal government keep their own list of qualifying crimes, and those lists differ more than most people expect.
What Counts as a Strike Under Three Strikes Laws
A strike is a qualifying felony conviction that moves a defendant closer to a mandatory long term sentence, usually 25 years to life on the third conviction. Most states build their strike lists around two categories: violent felonies and serious felonies.
Violent felonies typically include murder, rape, arson, and armed robbery. Serious felonies add crimes like burglary, kidnapping, and certain assaults that involve a weapon or serious injury.
A conviction that falls outside these categories, such as a simple drug possession charge or a low level theft, usually will not count as a strike, though a handful of states include broader nonviolent offenses on their lists.
Prior convictions generally must be final, meaning any appeals are exhausted, and juvenile adjudications are typically excluded from the count.

How the Federal Three Strikes Law Works
The federal three strikes law, codified at 18 U.S.C. § 3559(c), requires a mandatory life sentence for a defendant convicted of a serious violent felony who already has two or more prior convictions for serious violent felonies, or one prior serious violent felony plus one prior serious drug offense.
The statute names specific qualifying crimes, including murder, rape, and violent robbery, and it also covers any unnamed felony punishable by 10 or more years that involves force or the threat of force.
Serious drug offenses are defined as any offense punishable by 10 or more years under state or federal law.
The law includes a narrow defense: a defendant can avoid a robbery or arson strike by proving the offense involved neither injury nor the threat of injury.
Federal law also has a separate repeat drug offender provision under 21 U.S.C. § 841.
Before the First Step Act, two or more prior serious drug or violent felony convictions triggered a mandatory life sentence for a new qualifying drug offense.
The First Step Act reduced that mandatory minimum from life to 25 years. These two federal provisions are often confused with each other, but only the violent felony track under Section 3559(c) still carries a mandatory life sentence.
Crimes That Qualify as Strikes in California
California’s three strikes law separates offenses into “violent felonies” and “serious felonies,” both defined by statute.
Violent felonies under Penal Code Section 667.5(c) include murder, voluntary manslaughter, rape, and sodomy by force.
Serious felonies under Penal Code Section 1192.7(c) add crimes such as robbery, burglary of a residence, kidnapping, and any felony involving a weapon of mass destruction.
Some offenses only qualify as strikes with additional proof. Assault with a deadly weapon becomes a strike if the prosecutor shows the defendant used a weapon to inflict great bodily injury, and drunk driving that causes injury can qualify if the prosecutor proves the defendant personally inflicted that injury.
Before 2012, any felony conviction, even a nonviolent one, could serve as California’s third strike and trigger a 25 years to life sentence.
Proposition 36 changed that so the third strike itself must also be a serious or violent felony, with narrow exceptions for sex offenses and cases involving a firearm.
Senate Bill 483 built on this reform by allowing courts to resentence some people who received longer sentences under the older rules.
Crimes That Qualify as Strikes in Washington State
Washington calls its version The Persistent Offender Accountability Act, and Washington and California were the first two states to pass three strikes laws in 1993 and 1994.
Washington’s law uses the term “most serious offense” rather than strike, and it triggers a mandatory sentence of life without parole after a third qualifying conviction.
Most serious offenses include every Class A felony in the state, along with a specific list of Class B felonies named in the statute. The list also reaches beyond completed crimes.
Criminal solicitation or conspiracy to commit a Class A felony, any felony committed with a finding of sexual motivation, any felony involving a deadly weapon verdict, and attempts to commit a strike offense all count as most serious offenses in Washington.
Washington lawmakers have introduced reform bills in recent years. One proposal, Senate Bill 5945, would have excluded convictions committed before age 18 from the persistent offender count and allowed resentencing for people affected by those earlier convictions. As of early 2026, that bill had not advanced past committee.
How Qualifying Crimes Differ Across Other States
More than 20 states plus the federal government now have some version of a three strikes law, and each one sets its own rules for what counts and how severe the penalty is. A few examples show how much the details can shift from state to state.
Delaware narrowed its habitual offender law so that only violent felonies trigger the toughest penalties, removing many nonviolent crimes that used to qualify.
Maryland’s habitual offender statute, found in Criminal Law Section 14-101(b)(1), requires a fourth conviction for a crime of violence, plus three prior separate prison terms, before a mandatory life sentence without parole applies. That effectively makes Maryland’s toughest tier a four strikes law rather than a three strikes law.
Other states extend their lists further than the core violent and serious felony categories. Some include treason, large scale drug trafficking, felony theft, and bribery as qualifying strikes, even though these crimes are not violent in the traditional sense.
A defendant should check the exact statute in the state where charges are filed, since the label “three strikes” does not guarantee the same list of crimes or the same penalty from state to state.
Nonviolent Crimes That Sometimes Count as Strikes
Most three strikes lists center on violence, but a number of states also count certain nonviolent felonies. Large scale drug trafficking is the most common example, since many statutes treat high volume distribution as seriously as a violent offense.
Felony theft and bribery appear on a smaller number of state lists as well, usually tied to a minimum dollar amount or a public corruption angle.
This is where three strikes laws draw the most criticism. Stories of people receiving life sentences for nonviolent property crimes pushed several states to remove or narrow these categories over the past two decades.
If a strike list in a given state still includes nonviolent felonies, a defense attorney will typically look closely at whether the specific facts of the prior conviction meet every element required by the statute.
How Out of State Convictions Count as Strikes
A felony conviction from another state can serve as a strike, but only if the underlying conduct matches or is narrower than the qualifying offense in the state doing the sentencing.
Courts compare the elements of the out of state crime to the elements of the strike offense on the books where the new charge was filed.
If the out of state statute covers more conduct than the strike offense requires, prosecutors generally cannot use that conviction as a strike.
Washington applies a similar rule for sex offenses committed elsewhere. An out of state conviction with a sexual motivation finding can count as a most serious offense if the minimum sentence imposed was 10 years or more and the offense is comparable to a Washington felony.
Conclusion
Three strikes laws share a common goal of imposing longer sentences on repeat felony offenders, but the crimes that count as strikes are not the same from state to state.
Federal law and most states center their lists on violent and serious felonies like murder, rape, and robbery.
A smaller group of states also count nonviolent crimes such as drug trafficking or felony theft. Anyone facing a potential strike charge should check the specific statute in the state where the case is filed, since a prior conviction that counts as a strike in one state may not qualify in another.
