There are calls for NSW drivers to slow down when passing emergency vehicles.
New legislation, which may be passed this week, would require drivers to do just 40km/h in the move backed by police, paramedics and firefighters' unions.
This comes after two NSW police officers were struck by a car while setting up a RBT in Sydney's south west last month.
One of the officers had to have his right foot and lower leg amputated, while the other suffered a broken leg.
The 'Slow Down, Move Over' (SLOMO) laws were called on by NSW Labor leader Luke Foley in response.
"If (Premier Gladys Berejiklian) doesn't do it Labor will introduce the legislation itself in the next parliamentary sitting week," Mr Foley said.
