I am advised:
(1-2) The Centre for Road Safety at Transport for NSW invests significant resources in communications and engagement activities to educate the community on the safe use of our road network. The annual investment in road safety advertising campaigns exceeds $20 million.
The change in speed limit along Griffiths Road was communicated to the public through a media release and messaging signs, and by notification to visitors to the Safer Roads NSW website who have opted to receive alerts of speed limit changes. For a month following the speed limit change, those exceeding the speed limit were sent a warning letter instead of being fined.
The number of speeding infringements has been trending downwards, suggesting the communications efforts have been effective in educating drivers.
(3) Roads and Maritime Services spent $15,708 on variable message signs that were displayed along this section of road from 27 February to 26 March 2018.
