### maxspeed 



The question is  *What is the maximum speed allowed at this speed camera?*

This rendering asks information about the property  [maxspeed](https://wiki.openstreetmap.org/wiki/Key:maxspeed) 

This is rendered with  `The maximum speed allowed is {canonical(maxspeed)}`





### ref 



This tagrendering has no question and is thus read-only



This tagrendering is only visible in the popup if the following condition is met: `ref~.+`
