Most challenging aspects associated with introducing and passing interlock legislation:
There are a lot of factors for this problem, but primarily it is that everyone has a different agenda. Department of Transportation is not open to a lot of the changes, lobbyists can have some impact on that. Most of legislature consists “regular people” and politics come into play a lot.
Changes for program improvement being pursued:
 Possible inclusion of a 24/7 Program for drugged driving with a felony DWI. Increased funding for program staff to conduct service center checks and education.

Training available for judges, law enforcement, and lawyers:
We rely on AIIPA, TIRF, and NHTSA for training. We have a good relationship with other states, we network with them a lot about best practices. PADUI is responsible for the training of probation, law enforcement, and court staff. Highway Safety Instructors do the some of the training. The main problem we have is getting municipal officers the training they need. There is a master trainer, who is a state trooper, who does law enforcement training at the police academy. Defense attorneys need training and we have training going on in Lancaster county via Zoom. The hardest groups to train are judges and defense attorneys. Prosecutors do not see a role for themselves, but they need to educate the judges.We are also focusing on training probation. We have 4 trainings coming up. The master trainer has geared it towards probation officer questions.

Data Collection & Management

Agency responsible for collecting data: Awaiting data
Overview of Data Management: The DOT has a very old system and they are hoping to have modifications by 2025. They just do not have a workable data management system, we do not either. We collect data via an Excel file, but we want an automated process. We need to capture demographics but also need to be wary of security.
Barriers to data collection: We rely on vendors to provide us numbers for mileage, installs, and removals. There are seven vendors in the state and there are two counties in the commonwealth with probation departments that have their own IID program. They lease equipment from the vendors.
