An upright warning sign contains an exclamation mark. What should accompany it so drivers know the specific risk?

A blue disc prescribing which side to pass
A black patch giving the motorway junction number
A brown panel naming the nearest tourist attraction
A supplementary plate describing the nature of the dangerՃիշտ պատասխան

The exclamation-mark warning represents other danger, so a plate identifies the nature of the particular hazard. A route-number panel would provide navigation information without explaining why caution is needed.
