Dashcam vision shows the moment a 4WD rams a mobile speed camera 30 metres into a tree

A driver has deliberately rammed a mobile speed camera, forcing the vehicle along the side of the road before slamming it into a tree, injuring the technician inside.

The mobile road safety camera vehicle was parked on the side of Parwan-Exford Road in Parwan when a vehicle approached it from behind about 7.45pm on Sunday.

Dash-cam footage from the mobile speed camera vehicle shows a 4WD with a large bulbar intentionally slamming into the back of the vehicle pushing it about 30 metres forward into a tree, causing significant damage.

The victim, a 37-year-old Plumpton man, was in the passenger seat at the time and sustained non-life threatening neck and knee injuries.

He did not require hospitalisation.

The offending vehicle then reversed, pulled a U-turn and fled north-west along Parwan-Exford Road towards Bacchus Marsh, according to Melton Crime Investigation Unit detectives.

Police have released dash-cam footage depicting the moment the car was rammed in the hope someone may recall the incident and be able to provide information.

The vehicle has been described as a white 4WD with a silver bull bar on the front and a scoop on the bonnet.

 Investigators are appealing for anyone with information or dash cam footage to contact Crime Stoppers on 1800 333 000
