Maximum driving speed should not exceed 30 kilometers per hour. Below are relevant guidelines: 1. Reduce speed: Slow down when approaching curves and avoid overtaking. When driving on mountain roads, try to refrain from overtaking as these roads are relatively narrow with numerous curves. Before entering a curve, you may sound the horn to alert any potential oncoming vehicles. Pay attention to controlling your speed and maintaining distance. The most important aspect when driving on mountain roads is keeping a safe distance. While driving, not only should you maintain distance, but also extend your vision as far as possible to clearly observe road conditions and roadside situations. 2. Maintain distance: Due to the numerous curves and blind spots on mountain roads, keep a longer following distance than in urban areas when trailing other vehicles. This helps prevent rear-end collisions and provides you with sufficient reaction time and distance to handle unexpected situations.

After driving for so many years, I've seen all kinds of speed limits set for curves. The speed limit on curves is really not fixed; it depends on the specific road conditions. For small curves in the city, it's usually between 30 to 40 kilometers per hour, and you need to slow down when taking curves at intersections. Curves in suburban areas and mountain roads test your skills the most, especially steep slopes combined with sharp turns—speed limit signs are often set below 40. I remember once driving on a winding mountain road in heavy fog, with the speed limit sign showing 20 kilometers per hour. In such situations, it's better to go even slower. Curve speed limit signs are usually yellow with black text and can be seen about 200 meters before the curve. The safest approach is to ease off the throttle and apply a bit of brake in advance. Also, when taking curves in the rain, I recommend going 10 kilometers below the posted limit—tire slippage is no joke.

As someone who frequently goes on self-drive trips, I'm particularly sensitive about cornering speeds. Speed limits vary significantly across different types of curves: gentle curves on highway interchanges can maintain speeds above 80 km/h, while regular provincial road curves mostly have speed limit signs around 60 km/h, and hairpin turns are typically limited to 30 km/h. Two reminders for novice drivers: always check speed limit signs before entering a curve, as navigation systems might not provide timely alerts; also, when navigating consecutive S-curves, don't drive exactly at the minimum speed limit - leave some margin. Once on a mountainous road in Guizhou, I encountered an unmarked sharp curve and relied on experience to navigate it at 40 km/h - right after passing it, I saw a car that had crashed through the guardrail. The essence of curve safety lies in speed management.

When it comes to speed limits on curves, three key factors come into play: road classification, turning radius, and pavement conditions. Most urban expressway curves have a speed limit of 60 km/h, national and provincial highways around 50 km/h, while county and village roads typically range between 30 to 40 km/h. Sharp bends often feature triangular warning signs with black text on yellow background, with convex mirrors added on mountain roads. For cornering techniques, I usually start decelerating 200 meters in advance while keeping my eyes fixed on the exit point. When encountering unmarked rural curves, maintaining 30 km/h is the safest approach. Special caution is required on wet roads after rain - even driving at 40 km/h on a curve with 50 km/h limit could lead to skidding.
