The Bill for the adoption of the Australian Road Rules as a whole was passed in ACT LA late Dec 1999. However, this does not mean all the rules will become law in the ACT: if there is enough opposition individual regulations can still be disallowed. See my suggestions made to ACT Greens Member Ms Kerrie Tucker (21/01/00).
If you wish rules that you think are detrimental to cycling to be disallowed/ammended, there is still time to lobby this month (Jan). See Bulletin #7 for details on the rules and how to lobby your local MLAs and Bulletin #8 for more info.
