The Growing Threat of Automatic License Plate Reader (ALPR) Data Sharing and the Need for Transparency

In November 2025, the ACLU of Connecticut filed 94 public records requests with police departments across the state to obtain information about our state and municipal law enforcement's use of automatic license plate reader (ALPR) technology, like Flock Safety camera systems, to track drivers' movements and enable data sharing across state lines. These requests come amid warnings from experts who have examined how this Connecticut driver-location data has been accessed by out-of-state agencies, including law enforcement in states that criminalize abortion and gender-affirming care, and enforce unlawful and inhumane immigration operations.

This is the kind of unchecked monitoring that has a chilling effect on all of us. This surveillance structure is being used on people who are simply exercising their rights, whether that looks like visiting a health clinic, attending a protest, or going to worship.

We cannot and will not allow our personal data be shared, sold or used against us, our friends and families, and our neighbors. Together, we must learn more about this technology and establish ways to prevent the misuse of the information this technology collects.

Read our joint statement with CT Students for a Dream, Equality CT, Hartford Deportation Defense, Husky for Immigrants, and Reproductive Equity Now call on departments to suspend their use of ALPR technology until the state has a strong law in place to prevent the misuse, sharing, and selling of our personal data here.
