Signage: Vertical signs
Explanation
# Meaning of the number on the gradient sign
- The number indicates the **percentage of inclination** with respect to the horizontal (the **gradient** of the road).
- Example: **10%** means that for every **100 m** traveled in plan, the road rises or falls **10 m**.
- It does not determine the **speed** at which you should drive; it only warns of the **gradient**.
