Traffic Stops in Connecticut for Racial Profiling Analysis

Connecticut traffic stop records collected under the Racial Profiling Prohibition Project. The data is managed by the Institute for Municipal and Regional Policy at Central Connecticut State University and was last updated in September 2025. The project aims to monitor and prohibit racial profiling in law enforcement, supported by a National Highway Traffic and Safety Administration grant.

• Data collection is part of a formal, grant-funded state project with an advisory board, suggesting structured oversight.

Limitations
