Police find six kids unrestrained in car

A 25-year-old woman is likely to be charged for allegedly driving on a Melbourne freeway with six small children unrestrained in her car.

Police said they were "disgusted and appalled" after stopping her car on the Frankston Freeway, in Melbourne's south-east, on Tuesday night.

The Frankston woman is expected to be charged on summons for driving in a dangerous manner, careless driving and six counts each of having an unrestrained child in a motor vehicle.

Senior Constable Brad Cummins, who pulled the woman over, said two of the children, aged six and two, were standing up in the front seat while the other four - aged five, four, three and nine months - were also loose on the back seat.

He said it was a multiple fatality waiting to happen.

"I just spent the day investigating a road death involving an 11-year-old child," Sen Const Cummins said.

"When are people ever going to learn?"

Police on Wednesday were unable to confirm if the driver was the mother of all the children.

Acting Victorian Premier Rob Hulls described the woman's actions as out of line and that wearing a seatbelt was "absolutely crucial".

"It's obviously inappropriate and people have to understand that if you get into a car the first thing you do is whack the seatbelt on," he said.

"Particularly for kids, it's important that kids are restrained in cars."

Kidsafe Victoria state manager Aleks Natora said babies and small children were often hurt because they were not restrained in cars.

"These things keep coming up, that's our main issue, it's basically just irresponsible," Ms Natora told AAP.

Late last year, a Melbourne woman who was allegedly over the alcohol limit, crashed her car with an unrestrained child in it. The child is still in hospital recovering from serious injuries.

"Kidsafe Victoria is calling for a loss of licence, quite severe penalties, because it is a quite severe potential loss of life or serious injury," Ms Natora said.

"It reminds me of the dark ages. It's totally irresponsible.

"Certainly the lady had too many children for the number of seats - six children and the driver is way beyond anyone's capacity, let alone unrestrained..."
