What is an example of an investigative use of ALPRs?

An investigative use of Automated License Plate Readers (ALPRs) refers to employing this technology in a way that directly supports criminal investigations or monitoring of suspicious activities. Tracking vehicles around known drug houses exemplifies this investigative use. In such cases, law enforcement can gather data about which vehicles are frequently visiting a location associated with illegal activities, including drug trafficking. This information can help build a case or identify patterns relevant to ongoing investigations.

Counting traffic flow and monitoring vehicle speeds are important applications of ALPRs but are primarily focused on traffic management and safety rather than direct investigative purposes. Similarly, issuing parking tickets does not fall under investigative use; it is more about enforcement of parking regulations. In contrast, the tracking of vehicles near drug houses is directly linked to deeper investigative efforts aimed at understanding and addressing criminal behavior.
