Hanoi is very crowded and it has to face a lot of trafic problems. There are too many people using the roads. All types of vehicles are on the roads. It's very dangerous if you are not familiar with transportation here. There are some roads which are narrow and swampy when there is heavy rain. Moreover, some young people drive on the road dangerously. They don't respect the traffic rules strictly and they even play on the street with their motors. I think the government should enact stricter rules for road users.
