WAC. Can anyone point me towards any relevant laws that refer to cyclists' (or other road users') use of dual carriageways.
Also are there any regs within CTT that relate to warning signs for events?
Cyclists, along with every other pedestrian, horse-rider and carriage-driver can use any public highway that they're not specifically banned from. It's not a question of there being a law entitling cyclists to use dual carriageways - in this country it's legal to do anything, unless there's a law against it. And there's no law against cycling along dual carriageways.
There is, of course, a law which prohibits drivers from driving without due care and attention, which would (or should) include driving into cyclists, but that's very rarely observed IME.
