I just wanted to say that felonies and misdemeanors differ in the form of the severity of the action and the type of penalty.
For example, a DUI can be classified as a misdemeanor charge if it was the first offense and there was no subsequent injuries to another party.
Although many states differ but if the case is classified as a misdemeanor charge then the defendant might face a fine along with community service and a misdemeanor on their record.
Unlike with misdemeanor theft and minor shoplifting cases, a DUI can never be expunged because this violation is considered a public safety hazard and a record needs to be maintained in case there are additional charges in the future.
Additional charges might upgrade the offense from a misdemeanor to a felony charge. In DUI cases that involve the death of another party the charges are automatically classified as a felony even if it is a first time offense.
These cases involve charges of vehicular homicide that can lead up to 10 years in prison depending on the state.
