The family of a Melbourne man killed in a freeway emergency lane say they are disgusted the driver charged over his death is free on bail.

Tara Brennan, 27, has faced court accused of driving into a parked car on the side of the Western Ring Road on Saturday.

Father-of-three Alan Dunlop, 31, was crushed under the vehicle and died.

Mr Dunlop's ex-wife, Sarah Dunlop, said it was extremely hard to see Brennan front court.

"I just want to see ... justice served for my children, that I have to live with every day, who don't have their dad anymore," she said.

Earlier, police said Mr Dunlop had pulled over as he was feeling unwell.

Brennan was taken to hospital after the crash and charged with dangerous driving causing death.

She was later released on bail.

Mr Dunlop's mother-in-law, Zoe Stancliffe, said she was disgusted Brennan was released.

"Very angry ... not on bail. Definitely not," she said.

Brennan will return to court in August.

Ms Stancliffe said the family were supporting each other.

"We will be strong until then, we have to bury our loved one," she said.
