Last updated Sep 22, 2026|Official source

Summary

A person convicted of certain federal crimes can get up to 10 extra years in prison if the crime was tied to a criminal street gang and other conditions are met. "Conviction" also includes a juvenile delinquency finding for a violent or drug felony. A "criminal street gang" is an ongoing group of 5 or more people whose main purpose includes committing the listed crimes, whose members have carried out those crimes within the past 5 years, and whose activities affect interstate or foreign commerce. "State" means any U.S. state, the District of Columbia, or U.S. territories and possessions. The law covers four kinds of crimes: serious federal drug felonies with a maximum penalty of at least 5 years; federal violent felonies that involve use or attempted use of physical force; federal human trafficking, sexual abuse/exploitation, or transportation for prostitution; and conspiracies to commit any of these. The extra sentence applies only if the person knew the gang did those crimes, intended to help the gang or to keep or improve their rank in it, and was convicted within the past 5 years of one of the listed federal crimes, a state drug felony with a maximum of at least 5 years, a state violent felony involving force, any federal or state felony that carries a substantial risk that force might be used, or a conspiracy to commit those offenses.
