whistle tucked in to the left breast tunic pocket. Officers who had received a Commissioner of Police Commendation or HE Governor's Commendation were issued a plaited black, yellow and red lanyard for CP's Commendation, or red for Governor's. Vehicles Most police vehicles in Hong Kong are white, with a blue and red 3M retroreflective stripe around on the sides of the vehicle with wording "警 POLICE 察" in white, the only exception being the armoured personnel carriers specially designed for the Police Tactical Unit, which are wholly dark blue and with wording "警 POLICE 察" on a light blue background in white on the sides of the vehicle. Most police vehicles in Hong Kong are equipped with both red and blue emergency vehicle lighting. The vehicles which are assigned to airport duties have additional yellow emergency vehicle lighting and yellow rooftops required for all airport vehicles. All police vehicles are government property and so bear license plates starting with "AM". Since 2008, the Hong Kong Police Force have brought in the use of Battenburg markings for new police vehicles of the Traffic Branch for better visibility on the roads. In addition, these new vehicles show the Force crest on the front part of the vehicle, which the Force has not used in the design of new vehicles for the last two decades. The Hong Kong Police Force has ordered 10 new electric scooters for their officers to help reduce pollution in central Hong Kong. Emergency Unit, Police Tactical Unit, and Traffic Police have identification markings on the back of the car. For example, PTUD 1/3 means PTU D Team 1st Team 3rd car; EUKW 23 means Emergency Unit, Kowloon West region, 23rd car; and TKW 2 means Traffic unit, Kowloon West region, second car. Until 2007, EU, PTU, and TP vehicles had identification markings in a slightly different format. For example, “1/3 PTUD”, “23 EUKW”, and “2 TKW”. In popular culture The Hong Kong Police Force and its previous incarnation have been the subject of many films and television shows, including the locally produced Police Story film series, The Criminal Investigator, Infernal Affairs film series, Cold War, and OCTB. English language films featuring the HKPF include Rush Hour and Skyscraper.
