As in other states, Delaware law prohibits the operation of a motor vehicle while under the influence of alcohol, illicit drugs, or even legally prescribed medications. And while Delaware DUI law has a 0.08 percent blood-alcohol concentration (BAC) limit, the DMV points out that someone with a 0.05 percent BAC can still be arrested for a DUI if the officer can determine impairment from other evidence (such as reckless or sloppy driving). And because of Delaware's implied consent law, refusal to submit to a BAC test when stopped by an officer will result in a one-year license suspension.

Delaware Evaluation and Referral Program (DERP)
Those arrested on DUI charges are required to undergo an evaluation with the state, which costs $100 and takes at least an hour to complete. The DERP process consists of a written evaluation, social history survey, mental health screening, a one-on-one interview with a substance abuse counselor, and more. Information gleaned from this procedure will help the state determine the best course of administrative action, including alcohol education and treatment.
