The **danger warning signs** have the primary objective of **indicating the proximity of a danger that may be difficult to perceive in time**. These signs are crucial for alerting drivers to situations that might not be immediately evident, allowing them to take appropriate precautions.

- These signs are identified with a **P for danger** and cover a wide variety of situations, such as crossings, dangerous curves, movable bridges, level crossings, and more. Each of these signs warns about a specific type of danger that might not be visible until the driver is very close.

- For example, a sign indicating a **movable bridge** warns that the bridge may lift or rotate, interrupting traffic. Without this sign, a driver might not realize the danger until it is too late.


- Another example is the **dangerous curve** sign, which alerts about a curve that might not be visible in time due to the geography of the terrain or vegetation.


- Additionally, there are signs that warn about road conditions, such as **speed bumps or dips**, which might not be visible until the vehicle is very close, potentially causing damage or accidents if speed is not reduced in time.


In summary, danger warning signs are essential for road safety, as they alert drivers to dangers that might not be immediately evident, allowing them to react in good time.
