First, how many prior contacts do you have with law enforcement for alcohol-related traffic stops. If you were in an accident, if someone was injured, major or minor, there are consequences. However, the average offense is a first-time DWI with probation. The worst-case scenario is two years of probation known as SIS, suspended imposition of sentence. A good lawyer fights to do better than that. A bad lawyer just says, "Okay, you're going to plead guilty and get an SIS," which potentially you could have done without a lawyer at all.
