Warning

Falling rocks

W334 · temporary: TW334

Where

Especially in mountainous areas.

Purpose

To warn that rocks could fall on the carriageway from the left (W334, TW334) or from the right-hand side (W335, TW335).

Action

Slow down to be able to stop within their sight distance if a fall occurs or has occurred. Such falls occur more often when it rains and therefore reduce your speed further since your stopping distance during rainy weather will be longer.
