The State Government will be expanding the new Sarah's rule to also protect road side assistance vehicles and tow truck drivers in addition to Police and Emergency Service vehicles.
It follows the deaths of Sarah Frazer and tow truck driver Geoff Clark who were both killed when another vehicle ran up the back of them in a breakdown lane on the Hume Highway at Mittagong.
However motorists are being advised of some changes to the initial trial.
That includes: From September 26, motorists will no longer need to slow down to 40km/h on roads with speed limits of 90km/h or more when passing stationary emergency vehicles with flashing lights.
Instead drivers will need to slow down safely and move over to give them as much space as possible.
In speed zones of 80km/h or less, motorists will still need to slow down to 40km/h.
