My village has some traffic problems. First of all, children usually play on the road and it's very dangerous. And cattle and dogs usually run along or across the road. Next, villagers sell and buy things on the road. Besides, many people don't obey traffic rules. Many young people ride motorbikes fast and dangerous. Moreover, many roads are narrow and bumpy. In short, you should be careful so that you won't have any accidents while visiting my village.
