Why do driving schools hold onto ID cards?

[DeMila]

Driving schools do need to take the original ID card or temporary residence permit of students to the vehicle management office to input information, as without this input, students cannot take the exam. If students find that the driving school is illegally using their ID cards or leaking their identity information, they can complain to the transportation management office of the district traffic bureau. According to China's Resident Identity Card Law, no organization or individual may detain a resident identity card (except when public security organs implement compulsory measures for residential surveillance in accordance with the Criminal Procedure Law of the People's Republic of China). Those who illegally detain another person's resident identity card may be given a warning by the public security organs and fined up to 200 yuan; if there are illegal gains, such gains shall be confiscated.
