The New York City Police Department vehicle fleet consists of 9,624 police cars, 11 boats, eight helicopters, and numerous other vehicles. Responsibility of operation and maintenance lies with the NYPD's Support Services Bureau. A modified paint scheme, with dark blue (or black, for some Auxiliary units) body and white stripes on the sides was used for some divisions. The text was also white. This was phased out in favor of a modified version of the regular scheme, with the word(s) "AUXILIARY", "SCHOOL SAFETY" or "TRAFFIC" on the rear quarter panels and trunk.
