In order to be eligible for a hardship license after a DUI charge you must first enroll in DUI school. You must then wait to apply for the hardship license. For instance, if you refused to submit to the breath test you must wait a period of 90 days of the 1 year administrative suspension. If you did submit to the breath test but blew over the .08 then you must wait a period of 30 days. You must then take your certificate of enrollment to the DHSMV.
