These have been in use in NSW for quite some time. There is one on the hill leading down to wollongong. It is there for trucks and i am pretty sure it is there for compression braking in environmentaly sensitive areas.

At the end of the day. When a public serveant working for the RTA sees a picture of a cobra on the camera that has been triggered by noise, do you think they will know what ADR to check against?

I dont think we need to fear just yet.
