What does a two-way lane mean?
2 Answers
Two-way lane refers to a road with two-way traffic, totaling two motor vehicle lanes left and right. Special two-lane roads: In China, secondary and tertiary highways are basically two-lane roads. For secondary highways in plain and hilly areas, when the mixed traffic volume is large and it is difficult to separate the slow lane, fast and slow lanes can be marked, but they still belong to two-lane roads. Lane setting: Fourth-class highways should be designed as two-lane roads, and single-lane sections can be used for areas with low traffic volume. For highways designed at 120km/h, depending on traffic capacity requirements, they can be set as one-way two-lane, three-lane, or four-lane roads, i.e., two-way four-lane, six-lane, or eight-lane roads. For highways and first-class roads designed at 100km/h, when the traffic volume exceeds the capacity of four lanes, the number of lanes can be increased in even numbers.
As a veteran driver with over 20 years of experience, I must say that bidirectional lanes are those commonly seen on rural roads without central dividers, where vehicles must share the road in both directions. When driving on such roads, I always remind myself to stay on the right and keep a close eye on the headlights of oncoming vehicles, especially at night when it's particularly dangerous—speeding vehicles from the opposite direction could lead to a collision. Once on a mountain road, I witnessed a reckless driver attempting to overtake nearly causing an accident, which was truly terrifying. Safety comes first, especially when overtaking—make sure no vehicles are approaching and only do so in dashed line zones or permitted overtaking areas. These lanes are common in suburban areas and national highways; they are cost-effective but high-risk. Although smart driver-assistance systems are advancing, I still rely on experience and vigilance. My advice in summary: stay focused, don’t speed, and follow traffic line instructions—after all, road safety is a matter of life and death, and there’s no room for carelessness.
