What does this sign indicate?
Signage: Vertical signs
Sign P-16b indicates an uphill stretch with a steep ascending gradient, and the figure shown on it indicates the percentage of that gradient.
Explanation
Steep uphill gradient
The **P-16b sign** warns of a road section with a **very steep uphill gradient**.
The **figure on the sign** indicates the **incline of the gradient as a percentage**.
For example, a gradient of **10%** means that, over a **100-metre** stretch, the road **rises 10 metres**.
This sign serves to ensure that the driver:
- Adapts the **gear** and **speed**.
- Takes into account the **additional effort required from the engine**.
- Anticipates possible **loss of power** or the need to change down a gear.
