Open Data Policing aggregates, visualizes, and publishes public records related to all known traffic stops to have occurred in Maryland since January 1, 2013. Data is available for most Maryland departments and officers.

Maryland law requires all such agencies to report their data on a monthly basis to the MD state government; however, some datasets are incomplete or remain unreported. Where data sets are incomplete or missing from the website it is because they have not been reported to the state agency from which the site derives its records. Open Data Policing does not have access to, nor does it publish, the names of officers, drivers, or passengers involved in traffic stops.
