Exclamation Marks in Warning Sign

Exclamation marks are used to emphasize a warning. On warning signs, an exclamation mark is often used to draw attention to a warning of danger, hazards and the unexpected. These signs are common in hazardous environments or on potentially dangerous equipment. A common type of this warning is a yellow triangle with a black exclamation mark, but a white triangle with a red border is common on European road warning signs.
