One of the first road signs to be standardized in the USSR in 1927 was a triangle with a red border and an empty white field. In the training manuals of the time, the board was called “Silent Movement”. He warned of impending danger, unforeseen by other signs. The void in the center of the board symbolized these dangers.
Ten years later, in 1937, a new standard of road signs of the USSR was released, and then the exclamation mark settled there, and the sign itself was called “Danger”.
