It's true that there are a wide range of traffic problems in Vietnam. I think the main reason of these problems is that people's sense of road safety is not good. Firstly, there are too many vehicles on the road that leads to traffic jams, especially in the rush hour when people go out or get home. Secondly, there are traffic accidents every day so a lot of people are injured or lose their lives . Will reduce the population if it keeps going on.Another problem is that the road in our big cities are narrow and bumpy. They are easily flooded when it rains so heavily. In order to go on the roads safely, I think we should obey the traffic rules and traffic signs as well. i hope traffic in Vietnam will get better in the future
