Hello,
I’m having doubts about how to tag bollards that were added at a crossroad to prevent rat running:
Is this the right way? Won’t it prevent cars from turning?
Thank you.

Either it’s the right way, or we both made the same mistake 
https://www.openstreetmap.org/node/45232165#map=17/52.09790/5.11044
That isn’t the way I would map it. It gives a false impression that the roads connect, when they actually don’t. Also, like you suspected, the barrier on the intersection node would block vehicle routing through that intersection from any direction.
I would map it as two separate roads, with a short footway/cycleway/path connecting the bends of the two roads. Here’s a similar situation in my area that shows this:
https://www.openstreetmap.org/#map=19/48.43647/-123.38336
+1
But I say the connecting way is an highway=service, maybe even an hw=residential. The bollard as to be mapped as a point and blocks all routing. As the bollard can be lowered into the ground (bollard=rising) some vehicles may pass (emergency, city service, bus, … ?). So it is no specific way for pedestrains/cyclists.
Thanks much for the tips.

It might be easier and faster with JOSM than by using Id, but it can be done:
