Officers from Casey Highway Patrol are investigating after a traffic control officer was struck by a vehicle at a coronavirus testing site in Cranbourne yesterday.
Police were called to the Thompson Road site, which is set up inside an old retail building, following reports of the crash on Monday 18 October about 5.30pm.
Investigators have been told the driver of a Subaru sedan was called upon to move his car forward by one of the traffic controllers when he moved off at speed and struck the controller.
The 32-year-old driver's vehicle continued on before it crashed into the back of a Ford which crashed into a Nissan which then crashed into another Ford.
It's believed the Subaru then also spun and crashed into a Toyota in an adjacent lane.
The injured man, a 22-year-old from Mooroolbark, was taken to hospital with a suspected broken arm and other injuries.
The Lysterfield South driver underwent a preliminary breath test and was required to attend a station where he returned an evidentiary breath test result of 0.076.
Investigators are also awaiting the results of a blood test after the man returned a positive oral fluid test for drugs.
He is expected to be charged at a later date with numerous traffic offences.
WorkSafe are also investigating the incident.
