what do these road markings mean?

[glazbagun]

I thought that hatched broken white lines meant not to even enter unless avoiding a hazard- these are painted outside a narrow exit (see the two dropped paving slabs) onto a blind bend but I often see cars parked on them.

Is that worse/better in severity than a single yellow/zigzag/pelican crossing? I can't seem to find them with google

It's just a hatched protected area. Not ideal to park on, I'll admit.

Do not enter unless necessary IIRC, which is pretty meaningless.
