A wheel alignment measurement apparatus comprises six identical measuring heads to be arranged on the wheels of the vehicle and evaluation means. Four measuring heads are mounted at the four wheels of the vehicle. Two additional measuring heads are mounted on the measuring heads of the front wheels by means of rigid bars so as to be disposed in front of the vehicle. Each measuring head includes (a) a structure for detecting vertical angles in the form of a pendulum structure suspended freely movable about an axle and including a radiation source 6 emitting a vertical beam, (b) a structure for detecting horizontal angles including an outside radiation source arranged in the facing measuring head and emitting a horizontal beam, and (c) only one sensor line 9 in the area of intersection of the horizontal and vertical beams for contact-free detection of horizontal and vertical angles. An evaluation unit calculates the alignment data from the outputs of the sensor lines.
