In January 1988, the State Police changed the color of its uniforms. PSP troopers wore dark grey uniforms that confused them with some municipal police departments and Pennsylvania State Constables. By state law, no municipal (city, borough, or township) police department can wear the same exact uniform or color configuration as that of the PSP. Uniform – troopers to sergeants The current PSP uniform for troopers, corporals, and sergeants consists of a light gray uniform shirt with black shoulder epaulets. The PSP shoulder patch is worn on both sleeves of all uniform items. The PSP members are issued long sleeve shirts for the winter and short sleeve shirts for summer. However, PSP requires the black necktie to be worn year round. The uniform shirt consist of the trooper's nameplate over the right pocket and any awards the trooper has earned over the left pocket. The PSP is one of only five state police forces that do not wear a badge on their uniform shirts. The original PSP uniform was modeled after the Constabulary forces in Europe and they did not have badges. It is history and tradition for troopers today to carry their badges in a wallet along with their photo ID card. The uniform trousers are a darker gray color with a one-inch-wide black stripe on the leg. PSP shoes and/or boots are also black in color. The PSP duty belt is plain black leather. The
