There are a number of options, ranging from a verbal warning to going back to prison to serve the balance of your sentence. For example, let’s imagine you obtain a one-year suspended sentence, are placed on probation for three years, and, as a condition of probation, told not to drive a car. If you are caught driving a car during the 3-year period, you would more than likely be required to serve jail time.
Sometimes, there are other possible sanctions, such as increasing the level of supervision, placement in an intensive day program, or placement in an electronically monitored home confinement program. If you are seen as a threat to public safety or have committed additional crimes, you will see the walls of prison again in addition to being tried for any new crimes.
