Pa requires all individuals charged with a DUI to submit to a CRN evaluation. The evaluation involves answering a series of questions so that your drinking habits might be assessed to determine whether you are a problem drinker.
The CRN ( Court Reporting Network) evaluation is used to determine your dependency on alcohol or controlled substances and to determine the need for addiction treatment. It usually consists of a battery of questions but I suspect it could include a drug test in some counties. What happens next really depends on what track you are on ie the ARD track or trial track.

This is generally a standardized set of questions to determine if you need drug and/or alcohol counseling and, if so, how much. In many counties you will be given a breath test or a drug test as part of the process. It is important to get this done as failing to do so can delay disposition of your case
