How Many Lanes Does a Dual Four-Lane Road Have?

[LaArthur]

Dual four-lane refers to a road with 4 motor vehicle lanes, where 2 lanes go east (north) and 2 lanes go west (south). Dual carriageways in China: In China, secondary and tertiary highways generally adopt dual carriageways. For secondary highways in plain and hilly areas with heavy mixed traffic, it may be difficult to separate slow lanes. In such cases, lanes can be marked for fast and slow traffic, but they still count as dual carriageways. Fourth-class highways should be designed as dual carriageways, while single-lane sections can be used for areas with low traffic volume. Precautions for driving on dual carriageways: When the road is narrow or there are obstacles on the roadside, driving becomes more challenging. In such situations, remain calm, control your speed, and avoid driving too fast. Pay attention to your surroundings. If there are obstacles ahead and oncoming traffic in the opposite lane, large trucks should slow down or even stop temporarily to let passenger cars pass first. Avoid competing for the right of way to ensure safety.
