What does the following safety sign mean?
💡 Hint
The picture on a caution sign imitates the road facility that lies ahead (Enforcement Rule, Appendix 6). Learn to match picture features, such as towers and cables, an arched entrance, a car falling into water, or a locomotive, to the structure each one points to.
Answer: ③
Explanation
A picture of a bridge with cables hung between two towers is a caution sign warning of a bridge (Enforcement Rule, Appendix 6, No. 138-2). It is placed on the right side of the road 50-200 meters before the bridge; winds are strong on bridges and the surface freezes easily in winter, so slow down. A tunnel shows an arched entrance, a riverside road shows a car falling into water, and a railroad crossing shows a locomotive.
