Generally, the time limit in Guangzhou mainly depends on Guangzhou electronic eye to catch and shoot trucks during non-running hours. I have also seen traffic police catch individual trucks on the spot, but they all happened by accident, so most of them still rely on electronic eyes. However, drivers should obey the traffic rules. Guangzhou is a traffic law and it is inhuman, otherwise it will be their own loss. Be a good citizen who knows and abides by the law.
