I was wondering if you could appeal a suspension (possibly shorten it) for driving with a suspended license.

i managed to get myself in trouble and got 2 dui and I'm serving 18month suspension. Well, I've been working for the last 4 years basically since i got out of high school. Well, one day i happen to not have a ride to work and took my sisters car and drove to work and back. On my way back from work a cop pulled me over, i asked him why he pulled me over he told me my third brake light out. Then I proceeded to tell him i have a suspended license. long story short he gave me a ticket for Driving with a suspended license rather then driving under dui suspended license. Wondering if i could appeal the suspension possibly shorten it because i really have no other right to work. It's hard because i burn through all my time off missing days of work being unable to drive. which results "FIRED"
