Thank you for so very much responding. I am of the opinion that you can mark this node as both a barrier and a police checkpoint, based on the reality you saw here. Adding police=checkpoint as a tag to the node is definitely the right decision, but is it also possible to be more specific about the type of gate? Checkpoints like these typically have lift_gates (https://wiki.openstreetmap.org/wiki/Tag:barrier%3Dlift_gate). Is that the case here?

In summary, I believe the tagging would be either:

barrier=gate
Police=checkpoint

or

barrier=lift_gate
police=checkpoint

I hope to hear back from you. I wish you very well this holiday season.

Best,
