Traffic stops across Connecticut

Jake Kara
Data Editor

Connecticut police collect and report highly detailed data on traffic stops that are being used by researchers at Central Connecticut State University's Institute for Municipal & Regional Policy to try to identify racial profiling practices. The data is collected to comply with revisions passed in 2013 to a 1999 law, the Alvin W. Penn Racial Profiling Prohibition Act.

TrendCT has created this portal to give readers a sense of what some of the data "look like" at the statewide, police department and individual officer levels. This page shows the aggregate data for all departments across the state. You can also see profiles for each police department, and from there you can view data on individual officers in the department.

Minorities pulled over disproportionately

Across the state, the proportion of minority* drivers pulled over is larger than the proportion of estimated minority drivers: 31 percent of drivers stopped were minorities, while 25 percent of the estimated driving age population were minorities. This chart shows the percentage of traffic stops by perceived race of each driver. (*"Minority" is defined as all drivers not described as "white")

After dark, things change

During daylight, when an officer can see a driver, officers pull over minority and white drivers at a different rate than they did after the sun went down. Minorities made up 35 percent of daylight-hour stops and 28 percent of stops when it was dark out.

Men pulled over more than women

63 percent of stopped drivers were men.
37 percent were women.

Outcome of stops

On a 100% scale, this chart shows how many drivers were let go with written or verbal warnings or received an infraction, a misdemeanor summons or were arrested.

The median age of drivers stopped was 36 years old

This chart illustrates the share of stopped drivers by age group.

Most drivers pulled over were not local

28 percent were residents of the town where they were pulled over.
72 percent were non-residents.

Speed is often a factor

Across the state, speeding was the most common reason for pulling drivers over. Cell phone violations, defective lights and tinted windows were other reasons listed in the data.

Searches are rare

Officers searched 2.91 percent of drivers they stopped. This chart shows the percentage of all stops in which officers searched cars driven by white and non-white drivers.

When stops occurred, by hour, weekday and month

Which departments show signs of profiling?

CCSU researchers designed a series of measures to score police departments based on how much stopping practices varied from the state average, as well as gaps between population and stops to identify racial disparity. A point was assigned to a department for every threshold exceeded. Scores range from zero to nine and indicated below whenever scores were above zero. Zero indicates no sign of disparity. Any score higher than zero indicates some degree of disparity. Some departments, such as university police departments at Yale and the CSCU schools, do not correspond to towns and do not have scores.

If you don't see your town on the list, it may not have a municipal department. More than 50 Connecticut towns have resident state troopers and wouldn't be listed here.
