In many countries, fixed check-points are installed on the road. It could be done by Police, Customs, Tax services, Weight check... and even borders.

It would be great to have those marqued on the map as permanent Hazard " Check point". It has basically the same effect of a toll booth: You often need to stop there, or a least drive through at a very reduced speed.

This would be a great safety enhancement for both drivers and those manning those check points.
