According to Nolo, the most serious criminal offence is a felony. Offences may involve some severe threat of harm or physical harm to the victims. Similarly, they may include some offences, such as fraud schemes and white-collar crimes. However, some offences that are misdemeanours may get elevated to being a felony for second-time offenders. Additionally, a conviction for a felony such as a misdemeanour conviction may sometimes not lead to an individual being behind bars. Felonies may sometimes attract potential imprisonment. Moreover, the individual may be in prison for a short time to life imprisonment without any parole.

According to YourDictionary, felonies are punishable with an excess of twelve months of incarceration. When an individual threatens to cause some harm to another person but fails to carry the threat through, it is not a felony but may be taken as a misdemeanour. Such cases may attract a jail term of six months to a year. However, if the individual carries out the threat and causes bodily harm, it gets considered as a felony. Such felonies may attract up to twenty-five years in prison for the convicted individual.

Similarly, when an individual disturbs the peace, they may get charged. Such charges may come in many forms, including mobilization of an unlawful assembly, bullying of individuals or fighting in a public place. Such charges often get classified as misdemeanours. However, depending on the circumstances and the state that may surround the committed crime, it may get a felony count.

When an individual is found with ownership of vast drug quantities, their act may get classified as a felony. Similarly, when a person leaves the scene of an accident or a vehicular homicide, their act may be viewed as a felony. They may be imprisoned for a year or even for life.
