In the United States, felony classifications and sentencing guidelines can vary from state to state. Generally speaking, the lowest class of felony is often referred to as a “Class D” or “Level 4” felony in many states.

These are considered less serious felonies compared to higher classes, such as Class A or Level 1 felonies, which typically involve more severe offenses and carry harsher penalties.

Examples of crimes that might be classified as Class D or Level 4 felonies include certain drug offenses, property crimes such as theft of moderate value, some types of fraud, and certain non-violent offenses.

It’s crucial to know that each state has its laws and classifications for felonies, and what is considered a Class D felony in one state might be categorized differently in another. Some states may use different terminology such as “Levels” or “Degrees” instead of “Classes” to classify felonies. Therefore, the specific classification and penalties for the lowest class of felony can vary depending on the jurisdiction.
