Steep Descent Road Sign - 10% Gradient Warning #87786 (License: Personal Use)

The image shows a red-bordered triangular warning sign with a white background, featuring a black silhouette of a car descending a steep incline marked “10%”. This sign is used internationally (especially in Europe) to warn motorists of a significant downhill gradient that may require reduced speed, engine braking, or lower gears. The 10% grade means a vertical drop of 10 meters per 100 meters horizontally.

Used on roads approaching steep descents, especially mountain passes or hilly terrain; serves to inform drivers of potential brake fade or loss of control, aligning with user intent for road safety awareness and trip planning.
