Abstract
This paper describes research work undertaken in order to establish, in Belgium, permanent statistics about technical inspection of motor-vehicles. After having pointed out what information best characterizes the different aspects of technical inspection, the author describes the intermediate document devised for transmitting these data to the computer service. The different statistical statements these services can draw up are then described. In Appendix No to be found, with annotations, certain statistical statements based on information gathered during an experimental period of two months.
