South Africa
1. 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 South Africa?
South African learner-driver guidance distinguishes warning signs for steep gradients from regulatory speed restrictions. A descent may require a suitable lower gear and a speed below the legal maximum.

How should I approach a steep descent in South Africa?
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 South Africa?
Do not overtake towards a hilltop without a clear view and enough safe space. Follow priority controls at narrow sections and allow for the size and braking needs of oncoming vehicles.
