The mother of a son who tragically lost his life after a freak accident on the M4 is calling for barriers to be set up in the area.

The incident happened nine weeks ago near the Mamre Road off-ramp in Sydney’s western suburb of Penrith.

Cheryl, the man’s mother, tells Mark Levy nothing has been done about kangaroos making their way onto the motorway since the accident.

“We have driven up the M4 and I have seen at least four more dead kangaroos.

“I do realise that’s because we’re putting in new infrastructure out the back, this is where they’re coming from, but what are they going to do about this to prevent this happening?”

The calls comes as a driver fights for his life after being hit by a kangaroo near Lithgow, west of the Blue Mountains, on Friday.

The animal was initially hit by another car but was launched into the windscreen of the 32-year-old man’s car.

He suffered serious head and facial injuries and was airlifted to Westmead Hospital where he remains in a critical condition.

NSW Roads and Maritime Services have told Mark Levy all road safety barriers are “built to meet Australian and New Zealand standards”.

They say, on the road shoulders of the M4 where there’s a “reduced slope”, those types of safety fences “aren’t warranted”.
