摘要

The system has at least one early warning signal device and at least one second signal device after the first in the direction of travel, especially at a motorway or highway exit and/or entrance. The first signal device is arranged on at least one first traffic sign, especially one advising of the next exit and/or entrance. The second device is arranged on at least one subsequent sign, especially one immediately indicating the exit/entrance. The system has at least one early warning signal device (20), at least one second signal device (30) after the first in the direction of travel, especially at a motorway or highway exit and/or entrance, whereby both devices output a visual warning of a problem after the second device and at least one transmitter/receiver (10,10b) that interacts with the first and/or second signal devices, e.g. by radio. The first signal device is arranged on at least one first traffic sign (60), especially one advising of the next exit and/or entrance, and the second device is arranged on at least one subsequent sign (70), especially one immediately indicating the exit and/or entrance.
