There is a kind of middle lane of turning left. When a car wants to turn left in the road, he may enter into the middle lane of turning left and give a signal of turning left. When he thinks being safe he may turn left.

3. Specific item: Such as parking, there are three kinds of lines (its color are white, blue or red) in the roadside. Every line may park different kinds of cars. There are streets in some residential(住宅區) areas, and no car can park at any time or any period time.
