So last night I shared the ASZ on Morrison St with a delivery motorbike which had L plates on.
I mentioned to him that it was just for pedal bikes and his response was that it changed in February and they were allowed in similar to bus lanes that changed last month (as if I didn't know that one...)
I said I hadn't heard that and I would look it up.
So I've done my goggling and can't see any references to s178 of HWC being changed.
"Motorists, including motorcyclists, MUST stop at the first white line..."
I didn't get the impression he was trying it on, more that he genuinely thought it to be true and given the L plates I assume someone must have taught him it.
