Most states break their crimes into two major groups: felonies and misdemeanors. Whether a crime falls into one category or the other depends on the potential punishment. If a law provides for imprisonment for longer than a year, it is usually considered a felony. In most states, if the potential punishment is for a year or less, then the crime is considered a misdemeanor.
In some states, certain crimes are known as "wobblers," which means that the prosecutor may charge the crime as either a misdemeanor or a felony.
Behaviors punishable only by fine are usually not considered crimes at all, but infractions -- for example, traffic tickets. But legislatures sometimes label a behavior punishable only by fine as a misdemeanor -- such as possession of less than an ounce of marijuana for personal use in California.
