I have lived in Ha Noi for many years. Ha Noi is a big and busy city. There are lots of vehicles on the road all day. There are lots of cars, buses, taxis and trucks on high ways. Vietnamese people like moving by motorbike. Almost every family has a motorbike. The traffic jam is often at about 7 a.m and 5 p.m because it’s the time when people go to work or school and come back home. There are sometimes accidents on the road. Therefore, to reduce these problems, we need to obey traffic rules to reduce accidents as much as possible.
