TAC statistics show Casey has more people being admitted to hospital after a crash than anywhere else in the state.
The alarming figures place the City of Casey above Melbourne, Dandenong and Geelong for serious road trauma incidents.
The injury data shows that 969 people spent more than two weeks in hospital last year. This was a 10 per cent increase on the previous year.
The TAC’s Road Safety Quarterly Statistics report was released on Tuesday 6 September.
It revealed that 6266 people were admitted to hospital following transport accidents in 2015, a 5 per cent increase on 2014.
Figures show that 276 people were admitted to hospital after crashes in Casey followed by Melbourne at 231, Greater Dandenong at 223 and Greater Geelong at 203.
TAC chief executive officer Joe Calafiore said many people who are injured on Victorian roads make a full recovery but some spend a lifetime being dependent on others and unable to enjoy things that other people take for granted.
“We need every Victorian to think about the choices they can make, the cars they drive or the way they drive them, and make a commitment to ensuring every trip is as safe as it can be,” Mr Calafiore said.
