Just cycled by. Although there is some inconsistency at the northern part regarding motorcycles, the following signs are present:

At the crossing with Berkenlaan (i.e. South):
- only entry from this side (oneway=yes) for motor vehicles on >2 wheels
- maxwidth=2.3 except agricultural and delivery of goods/persons

On the northern side (crossing Rijksstraatweg) it shows: "no entry for motorcycles and vehicles on more than 2 wheels from this side" (C12) after 150m
(The Dennenlaan is also C12)
Then past house number 5 (so after about 150m), you get the actual sign, which is a C6 sign

I'll adjust it accordingly where needed
