What should I do if the traffic police check that I didn't stop and my driver's license was deducted? Is it illegal?

You are suspected of obstructing the execution of official duties. Every citizen has the obligation to cooperate with the staff of public security organs in law enforcement inspection. You didn't stop for inspection when the traffic police checked the vehicle. Although you didn't break the law, you were suspected of breaking the law, so the traffic police temporarily detained your driving license and driver's license. You have to go to the traffic police team to deal with it. There is no other way.
