A man had to be restrained by police and has been taken to hospital after he flipped his car in a fast food drive-thru in Somerville this morning.

Emergency services were initially called to the Eramosa Road store following reports the car had crashed into a bollard and flipped on its side in the drive-thru about 12.40am.

Further calls were then received by police stating the driver was acting in an aggressive manner and had assaulted other attending emergency services.

Police have been told the 23-year-old driver was able to free himself from the vehicle before he pushed a male paramedic and allegedly headbutted an officer from the Country Fire Authority (CFA).

The Tyabb man was restrained by police before he was able to be treated by ambulance paramedics and taken to hospital.

Hastings police are investigating that the man also abused staff at the first window of the drive-thru just prior to the collision and whether alcohol or drugs were a factor.

It is expected the man will be interviewed in relation to assault emergency service worker and traffic offences.

Anyone with information or who witnessed the incident is urged to call Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppers.com.au.
