What is the maximum speed limit for sharp turns?
4 Answers
When a motor vehicle passes through a railway crossing or makes a sharp turn, the speed should not exceed 30 kilometers per hour. Below is the relevant information: 1. Safety factor: When a motor vehicle passes through a railway crossing or makes a sharp turn, maintaining a speed not exceeding 30 kilometers per hour ensures a higher safety factor. 2. Relevant regulations: According to Chinese regulations, when a motor vehicle encounters situations such as entering or exiting a non-motorized lane, passing through a railway crossing, navigating sharp turns, or traversing narrow roads or bridges, the maximum speed should not exceed 30 kilometers per hour. Additionally, when encountering fog, rain, snow, sandstorms, or hail with visibility less than 50 meters, the speed should also not exceed 30 kilometers per hour.
Having driven for half my life, I'm all too familiar with sharp turns—there's no hard and fast rule for the maximum speed, it all depends on the situation. For tight turns like U-turns on mountain roads, I always keep it under 20 to 30 kilometers per hour. If the road is slippery, like after rain, I slow down to around 15 kilometers for safety. Why? Higher speeds cause severe body roll, risking a rollover—I learned this the hard way when I nearly drove off the road taking a turn too fast while rushing a delivery. My advice to new drivers: check the rearview mirror before turning, ease off the throttle, lightly brake, and coast through slowly—especially in taller vehicles with a higher center of gravity.
I worked in the traffic police for several years and handled many accidents related to excessive speed. There is no unified national standard for the maximum speed on sharp turns; it is usually based on local road signs. Generally, the speed limit for urban curves is 20 to 30 kilometers per hour. The key is to maintain vehicle stability and avoid loss of control, which can lead to injuries or fatalities. Under different road conditions, such as narrow bends or multi-vehicle sections, you must slow down to an even lower speed. I've also seen cases where modified cars were too powerful and skidded on curves, so don't push the limits—following the rules is the most practical approach.
As a car enthusiast, when analyzing the speed for sharp turns, I emphasize the physics principles. The maximum speed should not exceed around 30 kilometers per hour, mainly depending on the turning radius and tire grip. The smaller the radius, the slower you must go, otherwise the vehicle may skid due to inertia. I've tried driving a small car slightly faster at 35 km/h on dry roads, but on slippery roads, it's necessary to reduce to 25 km/h to prevent skidding. It's advisable to consider your vehicle's condition, such as SUVs with higher centers of gravity requiring extra caution.
