The utility model provides an automatic measurement device for driving speeds of an industrial vehicle in order to make up defects of manual detection and prior automatic measurement methods in prior industrial vehicle driving speed measuring technology. The automatic measurement device for driving speeds of the industrial vehicle includes a reflection board, a photoelectric switch unit and a trigger-type timer, wherein the reflection board includes a first reflection board and a second reflection board and the trigger timing unit is composed of a power voltage-stabilizing circuit, a signal processing circuit and a micro-processing and displaying circuit. When the vehicle passes through a trial pavement section, the photoelectric switch unit installed on the vehicle transmits and receives reflection signals of the reflection board and transmits information to the trigger-type timer. The timer records accurate time according to time difference of two trigger processes of the photoelectric switch, and then a re
