What shape is a ‘stop’ sign at a junction?

Explanation: To make it easy to recognise, the 'stop' sign is the only sign that's octagonal. The visibility from a junction where the 'stop' sign is used will be poor, even from the edge of the junction. You must stop and, if necessary, edge forward until you can see it's safe to drive out.
