[talk-au] Tagging Trucks (hgv) "Use low gears"

[Ross Scanlon]

Andrew beat me to it.

There is a speed restriction associated with the "Must use low gear 
signs" under the road rules.

It states:

"you must drive in a gear that is low enough to limit the speed of your 
vehicle without using the foot brake."

Unfortunately it's not a defined limit although in places there may be a 
speed limit sign for trucks and buses as well. eg on the Great Eastern 
Freeway heading towards Perth.

Cheers

Ross
