3. 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 Chile?

Chile’s official driver handbook explains the need to select a suitable gear on a descent and avoid coasting. A gradient warning does not replace a mandatory speed restriction.

How should I approach a steep descent in Chile?

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 Chile?

Avoid overtaking close to a crest or bend when the road ahead is not sufficiently visible. Allow for oncoming traffic and use the actual signs and passing space on a narrow road.
