A system for automatic vehicle identification and possible subsequent stopping comprises a base station and a mobile unit. The mobile unit (10) has a receiver (11), a decoder (12), two switches (13 and 22), a memory (14), a coder (15), a transmitter (16) and a bypass unit (28). The base station (operated by the police, say) sends a question (Q) signal towards a vehicle equipped with the mobile unit (10). The mobile unit (10) responds with a signal (R) identifying the vehicle. This R signal is received by the base station (20), processed and displayed and compared to database information about the vehicle. The inspecting body can decide to stop the vehicle automatically if it is discovered the vehicle is stolen. <IMAGE>
