Entering a construction zone on Expressway
There have been many accidents involving vehicles entering the area.

Accidents involving vehicles entering construction zones mainly involve collisions or contact with the leading edge of the zone or contact with barrier materials running parallel to the lane. However, there have also been serious accidents in which workers have been struck and killed by vehicles entering the zone. Please pay attention to the speed limit and change lanes with ample space. Also, please refrain from making reckless lane changes near the leading edge of the zone, as this is extremely dangerous.
