Road & transportStandard profile

Meanings

The MUTCD reserves an upward-pointing pentagon for school warnings, so the shape alone identifies the message before the legend is read. Reserving a shape for one subject is a device the Vienna Convention does not use.

Contexts: Road signage

A treaty binding only on its contracting parties. It prescribes sign categories, shapes and colours and permits national variants within them; it does not describe the signage of non-signatory states, notably the United States. Cited for category and design prescription, never for the traffic law of a particular country.
