I'm still interested in getting an answer.
It's not top priority just some information I was looking for - not like a charge has been laid or anything so it can wait longer.
Thanks for the information; I mean the most logical answer though is to just not use the colour combination at all.
I find it interesting and odd at the same time, why bother putting Subsection 62 (14.1) and to word it like that, 'to the front' if you simply have 62(14) which restricts it all together - I guess the devil is in the details, needed to specify for Blue/Red and which vehicles.
Ah, the law. Known to have contradictions throughout, unnecessary parts, vague terminology, and loopholes - granted some law is cut & dry and airtight.
Anyways I do appreciate your time and the information provided.
