The reason is that the Vietnamese people do not have awareness when participating in traffic. often occupy the roadway, road traffic.all of the causes that often lead to car accidents when in traffic, traffic congestion, .... the way to avoid the above is when participating In traffic we should wear helmets, we must not go in the opposite direction, not occupy the roadway, do not dodge road traffic, do not ride too fast. The above things will limit the Vietnamese people from traffic accidents. We hope that the Vietnamese people are always conscious to reduce the rate of traffic accidents in our country.
