Warning Sign
On warning signs, an exclamation mark is often used to draw attention to a warning of danger, hazards, and the unexpected. In Europe, this type of sign is used if there are no other appropriate signs to denote a hazard. When used in traffic signs a plate describing the hazard must be present. On an upright sign it is usually mounted under the exclamation mark.
