The New Milford Police Department is participating in a program meant to improve interaction and communication between officers and drivers during traffic stops..  The state Department of Motor Vehicles and New Milford Police are providing Blue Envelopes for Drivers on the Autism spectrum and Green Envelopes to Deaf/Hearing Impaired Drivers.  It holds a driver's license, registration and insurance card, and it includes tips on how the driver and officer can best respond to one another during a traffic stop. Drivers can keep the envelope in the glove box or visor so they can easily find it and hand it to a police officer.
