Welcome to the Massachusetts DUI Law Library. I have designed this electronic law library to serve as a resource for those looking for court decisions and legal information regarding Massachusetts DUI arrests, prosecutions, and trials. This is a work in progress and I will be posting periodic updates. The library contains more than one hundred Massachusetts DUI cases. It is divided into sections and each section contains case summaries. Click the case names to download a full copy of the case.
