Warning boards are triangular and white with black pictogram and red border. They are set up to draw attention to safety risks that are difficult for road users to anticipate or where the risk is greater than expected. All our warning boards are made of reflective material (Reflective type 3) which ensures that warning boards are visible from a long distance.
What are warning boards used for?
The warning boards warn, for example, of loose stones, descents and climbs, harbor quays and railway crossings.
In addition, there is a warning board with a pictogram of exclamation marks. It is used to supplement the other signs or in situations where a safety risk is not symbolized by a traffic sign in advance.
