What does two-way single lane mean?

[LaFinley]

Two-way single lane refers to a single lane that allows two-way traffic for vehicles, with a lane width of 3.5 meters. The following are relevant details: Setup conditions: Roads with a width of 6 meters uniformly have parking on one side; One-way roads with a width of 7 meters have parking on one side and guardrails on the other; Only when the effective traffic width reaches 10 meters is parking on both sides considered. Relevant regulations: According to the "Highway Route Design Specifications" JTG-D20-2006, Class IV highways should adopt dual lanes (two-way two lanes), and single lanes can be used for sections with low traffic volume and difficult engineering conditions; When the design speed is 20Km/h and it is a single lane, the lane width should be the lane width; The subgrade width for single-lane Class IV highways is 4.5m.

A two-way single lane road is a narrow path with only one lane, but it's used for both directions of traffic, somewhat like driving on a country road. Having driven for many years, I find these roads quite common in mountainous or remote rural areas, and they really test your driving skills. I've encountered them several times myself, like when going camping on winding mountain roads where a truck suddenly appears from the opposite direction. I had to quickly slow down and find a wider spot to pull over and let it pass. Safety always comes first, so I usually keep my speed around 40 km/h and honk in advance to alert oncoming drivers. Driving on such roads requires good judgment—no overtaking or speeding, maintaining proper distance, and ideally traveling in good weather. Though a bit nerve-wracking, driving slowly allows you to enjoy the scenery, improve your skills, and avoid accidents.

I've always been interested in road planning. A two-way single lane road, simply put, is one lane serving traffic in both directions, typically found in budget-limited areas like rural or mountainous regions. From a design perspective, it's low-cost but high-risk. I understand some areas have added passing zones to improve safety. When driving, I pay special attention to traffic signs and actively yield to oncoming vehicles, never risking overtaking. Research shows these roads are gradually being replaced during urbanization, with more dual lanes expected in the future. As a driver, I strictly adhere to speed reduction and horn usage rules, finding in practice that proper communication can reduce conflicts. I hope more people will pay attention to the evolution of road safety.

When I first started learning to drive, I was quite intimidated by two-way single-lane roads—where only one lane exists but vehicles from both directions must share it, like the rural roads near my home. My palms were sweaty the first time I drove on such a road. My instructor taught me to slow down, watch for oncoming traffic, and find a spot to pass. Now I can handle it. The key lessons are: don’t speed (keep it under 30 km/h), honk when spotting an approaching car, and wait for the other driver’s reaction. This helped me develop judgment for distances and improve reflexes—great practice for new drivers.
