How to map no stopping signs?

[Coehill]

Is there a recommended way to tag “No Stopping” signs on roads? Similarly, what about “No Camping” signs?

Depends on the object as restriction or with parking key.

There is the traffic_sign key. The actual value depends on the designation assigned to the sign by each country’s roads department.
