Abstract: (1) Problem to solve: After a primary car accident, a driver may be too embarrassed to take proper measures, and this increases the risk of a secondary car accident. The purpose of the present invention is to prevent such a secondary car accident. (2) Solution: After the primary car accident, vehicles passing through from behind the accident car are notified of the accident in various ways, there are many cases in which some of the vehicles do not properly recognize the primary car accident. The present invention aims to prevent a secondary car accident in advance by using ″the secondary car accident prevention banner″ to let the vehicles recognize the primary car accident immediately. ▶ Tips for using a safety banner in case of a primary car accident: 1. Take out a safety banner that has been stored in the accident car; 2. Attach rubber suction pads on the top end of the safety banner to the rear windshield of the accident car; 3. Let a vehicle running behind the accident car be informed of the occurrence of the accident by displaying the safety banner on the back of the accident car; 4. The driver moves to a roadside and reports the car accident to 112 and 119. (3) Effects: Compared with a conventional warning triangle, ″the secondary car accident prevention banner″ is 5 to 10 times the size of the warning triangle, so the visual effect allows the banner to be noticed at a distance of 50 to 100 m. Therefore, it can be expected that the risk of a secondary car accident caused by a vehicle behind the accident car is reduced. (4) Drawings: Refer to drawings in the attachment.
