I live in Vietnam and have a lot of traffic problems in the big cities of my country. Firstly, there are too many people using the road, especially during rush hour when people run out to work and school or home from those places. Second, there are too many vehicles on the road leading to traffic jams. Another problem is that many of the roads are narrow and bumpy. Fourth, every day there is a traffic accident that causes many people to lose their lives or be injured. So, to travel safely, I think we should obey traffic rules and traffic signs. Furthermore, due diligence is essential.
