The apparatus comprises in combination a plurality of pulse transmitter means, a first of which is positioned on the rear wheels of the vehicle, and a second of which is positioned on the gear-box drive of the vehicle, and a third of which is positioned to record movement of a tape means or the like which unwinds in accordance with movement of the vehicle along a test course. In a modification, the vehicle moves between two fixed exterior datum points defining a path along which the vehicle is moved to effect measurement. For verifying distances and corresponding times in taxi-meters, the apparatus comprises a portable variable speed motor, a digital tachometer combined with the motor, a chronometer, a quartz standard emitting vibrations and serving for calibration of the chronometer, and an optoelectronic transducer adapted to sense changes of the price indicator in the taxi-meter.
