Does the traffic police of Rizhao Qingdao Road check the helmet violation?

Not against the rules. According to China's traffic laws and regulations, it is illegal to ride a motorcycle, an electric car, a bicycle and other vehicles that need to wear a helmet if they don't wear a helmet. Traffic police have the right to investigate and deal with violations of helmet wearing regulations. Therefore, in Rizhao, Qingdao and other places, traffic police can inspect and punish illegal acts of wearing helmets when performing traffic management tasks on the road.
