However the introduction of a new road rule has seen him breathe a sigh of relief.

The introduction of the 'Slow Down, Move Over' road rule will protect all those who work in uncontrolled dangerous situations on our roads.

This includes tow truck drivers and roadside assistance personnel.

The rule came after 23-year-old Sarah Frazer and NRMA tow truck driver Geoff Clark were killed by a truck on the Hume Highway near Mittagong in 2012.

Sarah's father Peter Frazer said "no one slowed down to give these vulnerable road users the space they needed to be safe".

"I know this because Sarah had earlier left me a voicemail saying cars and trucks were passing her at high speed just centimetres from her vehicle," Mr Frazer said.

"Sarah shouldn't have had to fear for her life and neither should those who protect and assist our community."

Mr Smith said dangerous and distracted driver behaviour has put his life at risk on a daily basis.

"The only time we've ever felt safe on the highway was when we had a police vehicle with us," he said.

"It's almost like a game for some cars to see how close they can get.

"One of our biggest priorities is to get people into tow trucks and vehicles quickly."

Mr Smith said while most occupations had Occupational Health and Safety laws, the absence of the 'Slow Down, Move Over' rule left a gap in safety for his occupation.

"Everyone deserves to be safe. The safer they can make our job, the easier it is. It's not hard to slow down," he said.

"We've been lucky we haven't lost more lives of people. It can happen in a blink. When it happened to Geoff, it devastated the community.

"It doesn't go away, nothing changed. It's taken all those years to change, it was good luck no one else was killed."

Mr Smith called on the community to abide by the new rule.

"We're relieved the rule has come out and we want people to pay attention now," he said.

"Observe the fact there are people working and accidents happen quickly. It'll keep a lot more people safe."
