New road rules relating to roundabouts came into effect on the 1st November.
Now drivers must indicate their course through a roundabout when approaching, and quickly indicate left just before exiting a roundabout.
In Murwillumbah there are at least five major roundabouts.
Other important rules were created too: A driver cannot hold a mobile phone AT ALL now (thank you), Drivers cannot even hold a mobile anymore, and GPSs and DVD players must be commercially secured.
An excellent summary of the new NSW road rules, with a link to the new rules from Roads and Maritime Services (formerly the RTA) themselves can be found here.
