Wellesley Police Cruisers have had plenty of changes over the years. Since the 1980's, the primary vehicle used in Wellesley has been the Ford Crown Victoria sedan. The department did have Ford Crown Victoria station wagons, which were used in a backup capacity for the ambulance. The station wagons were equipped with minimal basic life support gear and a stretcher.
The department had a solid dark blue color for many years with "To Protect" and "To Serve" on either side of the door with the department seal. Cars with regular assignments such as the Sergeant or the Safety car had extra markings.
The department switched to a black and white paint scheme in the mid 1980's. The department also switched to numbering cars with the unique BAPERN numbering system. Wellesley was assigned cruiser numbers from 1401 to 1430.
In the early 1990's, the department swtiched to a light blue and white design which was similiar to the MBTA Police Department.
The late 1990's through the present day saw a change back to the traditional blue and white color scheme (very dark blue). The Wellesley Police seal was removed in favor of the bold "Wellesley Police" and wave.
The department also streamlined the interior of the vehicle, making every car the same on the inside. This allowed the officer to get into any car and have all the buttons, controls, laptop and switches in the same exact position.
