Many drivers are not familiar with the traffic sign that shows a red dot with a directional arrow. Failure to comply can result in fines and penalties.

The signs with the red dot are usually ordered by the local authorities to relieve traffic jams and accidents on particularly busy routes. If the “red route” is used, the regional radio stations usually also provide information about the diversions and explain how they work. The red dot, for example, helps drivers find an easy way through difficult traffic situations.
