When vehicles meet on mountain roads, the uphill vehicle should yield to the downhill vehicle. Below are the relevant details: 1. Overview: When vehicles encounter a slope on low-grade icy or snowy mountain roads, the downhill vehicle faces significantly greater braking difficulty due to gravity compared to the uphill vehicle. Therefore, the uphill vehicle should yield to the downhill vehicle. 2. Additional Notes: On roads without central barriers or center lines, when vehicles approach from opposite directions, the following rules apply: slow down and keep to the right, maintaining a safe distance from other vehicles and pedestrians; on obstructed road sections, the unobstructed vehicle has the right of way; if the obstructed vehicle has already entered the obstructed section while the unobstructed vehicle has not, the obstructed vehicle proceeds first.

I remember this oncoming traffic issue is quite crucial when driving on mountain roads. Many traffic regulations stipulate that downhill vehicles should yield to uphill vehicles, mainly because uphill cars lack sufficient power. If braking or gear shifting isn't handled properly, they're prone to rolling back or losing control, while downhill vehicles have gravity assisting them, making control easier. I've personally experienced this on steep slopes - once I didn't yield to an uphill car and almost rear-ended it. I've learned my lesson since then. Our mountain roads are narrow and often foggy or muddy, so safety comes first. Next time if there's an uphill vehicle coming, I'll proactively stop or pull over, patiently waiting for them to pass first to reduce accident risks. Remember to maintain safe distances and don't get too close to cliff edges.

Ever since I started learning to drive, I've known the rule for encountering vehicles in mountainous areas: downhill traffic must wait for uphill traffic to go first. The reason is that uphill vehicles have difficulty accelerating, especially manual transmission ones. If they stop and restart midway, the engine can easily stall. Meanwhile, downhill vehicles have greater momentum, and braking can easily slow them down. Driving instructors repeatedly emphasized this in driving school, saying it's an international convention to reduce chain accidents. In actual driving, I adhere to this principle, such as checking oncoming traffic before curves and using horns or flashing lights to communicate. Don’t underestimate this—mountain weather is unpredictable, and conditions like rain or snow make it even more dangerous.

Driving in mountainous areas is truly challenging, especially when it comes to deciding who goes first during encounters. I've tried several scenarios. Generally, vehicles going uphill have the right of way because climbing is more strenuous, and sudden deceleration can strain the engine. Once, I didn't yield while going downhill, and the uphill driver flashed their lights aggressively as a warning, making me realize the danger. Later, I checked the traffic rules, which clearly state that downhill traffic should yield to uphill traffic to avoid congestion or collisions. It's best for everyone to develop this understanding—don't rush or compete for the lane; safety comes first.
