What must you be aware of when you see this road traffic sign?

This traffic sign indicates a risk of falling rocks or debris on the roadway. When you encounter this sign, you should remember the following:

1. **Avoid stopping and parking**: It’s crucial to keep the flow of traffic moving, as stopping can lead to accidents, especially if vehicles behind you are unaware of the hazard.

2. **Stones may be lying on the roadway**: This warns drivers that loose material might be present, which can pose a hazard to vehicles, especially two-wheeled ones.

3. **Vehicles in front may brake suddenly**: Due to the potential dangers signaled by the presence of falling rocks, vehicles ahead might need to brake sharply, which can lead to collisions if you're not prepared.

Recognizing and understanding the implications of this sign helps ensure safety on the road, as it prepares drivers to respond appropriately to hazardous conditions. Always stay alert in such areas and maintain a safe distance from other vehicles.
