Driving while suspended (DWS) can be a violation, a misdemeanor, or a felony depending on the underlying reason for the license suspension. [Driving while revoked is similar.] Someone who drives while suspended for failing or refusing a breath or blood test or for a misdemeanor DUI conviction commits the crime of misdemeanor driving while suspended.
If convicted of misdemeanor DWS, a defendant faces possible jail time, fines, and probation. There is a minimum $1,000 fine for someone caught driving with a suspension for a DUI conviction. Your car may be towed as well.
You will not be kicked out of diversion if you receive a driving while suspended ticket (unless you have alcohol in your system / possession). However, driving while suspended will violate your probation if you are on probation for a DUII conviction. Driving while suspended convictions can quickly become expensive.
They do not suspend your license for an additional length of time if you are convicted of driving while suspended (unless you have so many convictions that you become classified as a "habitual offender").
