How should you act at a point of danger indicated by this sign?

Your answer is correct. This sign warns of a danger area where loose material or debris may be on the road, which poses risks such as skidding or flying stones.

The rules to follow here are:

1. Avoid rapid acceleration because sudden increases in speed can cause loss of traction on slippery or loose surfaces.

2. Avoid sudden maneuvers like quick turns or abrupt braking, as these can lead to skidding or accidents on unstable road surfaces.

3. Maintain the greatest possible distance to the vehicle ahead to ensure enough reaction time if that vehicle suddenly slows down or kicks up debris.

Following these precautions helps maintain control of your vehicle and ensures safety for yourself and others near this hazard.
