Sign Q10 warns you of what road condition?

The sign Q10 specifically indicates the presence of speed bumps or raised obstacles on the road. This type of signage is crucial for alerting drivers to reduce their speed and navigate carefully in order to avoid jolting or losing control of their vehicles over these bumps. Speed bumps are designed to enhance safety, especially in areas where pedestrians may be present or where traffic needs to be calmed for any reason. The warning helps to prepare drivers for the change in road surface and ensures that they can adjust their driving accordingly, enhancing overall road safety.
