Four people have died and a teenager is fighting for life after a car crash in Victoria’s west.

Emergency services remained at the scene of the crash on Wannon-Nigretta Falls Rd at Bochara on Saturday evening after a car carrying five females lost control and hit a tree.

Police said the crash was reported about 9.30am.

Four people died at the scene.

The fifth occupant of the car, a teenage girl, was flown to The Alfred Hospital with upper body injuries, an Ambulance Victoria spokesman said.

The teenager remained in a critical condition as of Saturday evening, a hospital spokeswoman confirmed.

Officers believe the five occupants of the car were teenage girls local to the area, Nine News reported.

Victoria Police could not confirm the ages of the five people on Saturday evening as the car’s occupants were yet to be formally identified.

“Hamilton is a very close-knit community, and there’s five people involved in this and all their families and all their friends,” Victoria Police Sergeant Ryan Nelson told reporters.

“It’s going to hit the town really hard.”

Sgt Nelson described the scene as horrific and said police wanted to give people answers about what happened.

The speed limit on Wannon-Nigretta Falls Rd is 100km/h.

A Country Fire Authority crew was among the first responders to attend.

Major collision investigation unit detectives were probing the crash on Saturday.

Victoria Police urged anyone who witnessed the crash to contact them.

More than 120 people have died on Victoria’s roads so far this year, compared with 96 during the same period last year.
