Functions and Powers of Traffic Police and Security Personnel at Public Security Checkpoint in Zhangjiagang City, Jiangsu Province

Now the Zhangjiagang estuary is not under the control of the traffic police, but under the control of the public security patrol brigade. Auxiliary police can stop vehicles and pedestrians under the guidance of the police. Suzhou has made special legislation this year, and there are laws to follow. As for asking for a urine test, it is estimated that your or your peers' identity information has drug-related records in the system, so it is not too much for them to do so.
