A first Driving After Revocation charge is a misdemeanor punishable by up to 90 days in jail plus fine, though executed jail time is rare for a first offense. It would also result in at least a 30 day additional license revocation period, if convicted. It would typically also be a probation violation on the previous DWI conviction, and jail time could result from that. To avoid such a criminal charge, avoid Driving After Revocation. If already charged, retain a defense lawyer and fight it.
If you just recently lost your license, you could attempt fight the suspension (if within 30 days). Also, you can work with the driver's license bureau and have an interlock device installed in your car, which will allow you to drive.
While your license is suspended/revoked......DO NOT DRIVE. If caught you will be charged with another crime.
