About Under-signs: explanation, restriction, exemption and distance: which statement is correct?
The under-signs '500 m' and '↑500 m↑' mean exactly the same thing: both simply indicate the distance to the main sign.
An under-sign with the word 'uitgezonderd' (excepted) plus a bicycle symbol means the traffic sign applies TO cyclists specifically, and only to them.
If an under-sign at an E-parking sign shows days and hours, the parking ban still applies all week — the under-sign is just extra information.
An under-sign contains a further explanation OF THE TRAFFIC SIGN; without a main sign an under-sign has no independent effect.
Explanation
trap: under-sign decoupled from the main sign. An under-sign contains **a further explanation OF THE TRAFFIC SIGN**; without a main sign an under-sign has no independent effect
