I live in Vietnam and there are a lot of traffic problems in big cities in my country. Firstly, there are too many people using the roads especially in the rush hour when people run out to work and school or get home from those places. Secondly, there are too many vehicles on the road that leads to traffic jams. Another problem is that many roads are narrow and bumpy. Fourthly, there are traffic accidents every day so a lot of people lose their lives or are injured. So in order to travel on the roads safely, I think we should obey the traffic rules and traffic signs as well. Moreover, carefulness is very necessary.

I live in Ho Chi Minh City and I know very well about the "evil" traffic jam or in other words the traffic jams here. The traffic jam in Ho Chi Minh City has been discussed a lot for decades. Many solutions have been proposed, but all are just ideas, in a qualitative manner, expressing will without quantitative proof, so there is no persuasion. That is why the public authorities as well as the people just listen and discuss, but in the end, no one can accept any solution. The result "stuck" is still completely "stuck", "stuck" is still completely "stuck", moreover "stuck" and "stuck" is more and more serious.
