The death of a man earlier this week has prompted a renewed focus on road safety, particularly for broken down drivers and those who stop to help them.

A man in his 20s was hit and killed on the M2 in Baulkham Hills on Tuesday after he pulled over to inspect his broken down truck.

The incident has shone a spotlight on the need for drivers to be more careful when passing accident sites.

From Septemeber, the NSW Government will introduce the Slow Down, Move Over law which will force drivers to slow down to 40km/h and leave extra room when passing emergency services.

The rule will cover police and firefighters but roadside mechanics, tow truck drivers and good Samaritans won’t be protected.

Safer Australian Roads and Highways founder Peter Frazer says the rule needs to be extended to protect everyone.

After losing his daughter Sarah in a similar accident, he tells Ben Fordham it’s a problem of “epidemic proportions”.

Peter and his sons are members of the Rural Fire Service and he says “it doesn’t make sense” they’re protected and others aren’t.

“The NRMA who are out there looking after 2.6 million Australians in New South Wales aren’t going to be covered.

“If we’ve people out on highways looking after those who are vulnerable, let’s make sure they’re protected.”
