10. Slope

A slope is a section of road that rises or descends noticeably. A steep slope can affect vehicle speed, braking distance, traction, visibility and the ability of heavy or low-powered vehicles to maintain a steady speed.

Warning signs may indicate a steep ascent or dangerous descent and may show the gradient as a percentage. Drivers should adjust their speed early, select a suitable gear and remain prepared for slow vehicles, bends and changing road conditions.

What does a steep-slope warning mean in China?

A steep-slope warning identifies a gradient hazard. Article 46 also limits an ordinary motor vehicle to 30 km/h while descending a steep slope; specified tractors, battery vehicles and wheeled special machinery have a 15 km/h ceiling. Obey any lower restriction and slow further for braking, grip, visibility and traffic.

How should I approach a steep descent in China?

Reduce speed before the descent and select a suitable gear to help control the vehicle. Keep enough following distance and avoid building up speed that requires continuous heavy braking. A warning gives no fixed safe descent speed: the gradient, surface, visibility, load and vehicle can require a speed well below the legal maximum.

What should I check when meeting or overtaking on a slope in China?

On a narrow slope, uphill traffic normally goes first. However, a downhill vehicle already part-way down has priority if the uphill vehicle has not yet started climbing. Narrow mountain roads also have a separate rule favouring the side away from the mountain.
