Should uphill traffic yield to downhill traffic when vehicles are moving?
2 Answers
When vehicles are moving, uphill traffic does not necessarily yield to downhill traffic. Generally, downhill traffic yields to uphill traffic. Here are the relevant rules for uphill and downhill driving: 1. Right of way depends on the situation: On narrow slopes, the uphill vehicle has the right of way. However, if the downhill vehicle is already midway on the slope while the uphill vehicle has not yet started ascending, the downhill vehicle should proceed first. 2. Reason for uphill priority: When both uphill and downhill vehicles are at opposite ends of the slope, the downhill vehicle should go first because high-speed downhill driving poses significant safety risks. Conversely, if the uphill vehicle proceeds first, any potential accidents would likely result in less severe consequences compared to downhill accidents.
When driving on uphill and downhill slopes, it is generally recommended that vehicles going uphill yield to those going downhill. This is a safety-based rule of thumb because once a downhill vehicle gains speed, gravity propels it downward, significantly reducing braking effectiveness and making it difficult to stop within a short distance. If an uphill vehicle blocks the way, the downhill vehicle may lose control and collide. I have encountered similar scenarios multiple times on mountain roads—when uphill vehicles promptly pull over to yield, downhill vehicles can pass smoothly, ensuring safety for both. Conversely, if neither yields, the risk of accidents skyrockets. Therefore, I make it a habit to proactively slow down and give way when going uphill, especially on narrow sections or blind curves. New drivers can avoid many troubles by adopting this practice, as road safety should always come first.
