A police motorcycle is a motorcycle used by various police departments. They may be custom designed to meet the requirements unique of a particular use. A police motorcycle is often called a "motor" by police officers in the United States. Similarly, motorcycle units are known as "motor units" and motorcycle officers are known as motor officers. The maneuverability of the motorcycle on crowded streets offer advantages not provided by larger, more traditional police vehicles. The motorcycle's relatively small size allows it to get to accident scenes more quickly when incidents such as traffic collisions slow down access by four-wheel vehicles. Police motorcycles are also used in police funerals, VIP motorcades, and other special events. == History == Police officers have used motorcycles—primarily for the enforcement of traffic laws and as escort vehicles—since the early 20th century. Chief August Vollmer of the Berkeley Police Department is credited with organizing the first official police motorcycle patrol in the United States in 1911.〔(【引用サイトリンク】 work=Berkeley Police Department Online, City of Berkeley, CA )〕 However, several police forces around the country reported using motorcycles as patrol vehicles earlier. Harley-Davidson credits Detroit, Michigan as being the first purchaser of police motorcycles in 1908. The police department in Evanston, Illinois also purchased a belt-driven motorcycle for its first motorcycle police officer in 1908, and the Portland, Oregon Police Bureau had a police officer who used his personal motorcycle to patrol the city as early as 1909. The role of the motorcycle as inexpensive public transportation evolved in the 1930s, and their use by police and the armed forces also grew, providing a stable production market for the more utilitarian machines, especially as Europe rearmed after World War I. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Police motorcycle」の詳細全文を読む スポンサード リンク
