The Danbury Police Department is providing envelops for drivers with special needs as part of a program designed to enhance communication between the police and the driver.  A person on the autism spectrum, or someone who is deaf or hard of hearing, can place their insurance card, registration and driver license in it, so they can hand it to the officer during a traffic stop. On the outside of the envelope are helpful tips and instructions on how the driver and officer can successfully communicate with each other.  The program is sponsored by the state Department of Motor Vehicles and the Connecticut Police Chiefs Association.
