POLICE have called for witnesses after a convoy of vehicles drove dangerously on the Western Highway between Ararat and Beaufort on Saturday.
Investigators have been told that four cars and up to six motorcycles were all travelling east in convoy around 5.50pm.
Victoria Police spokeswoman Creina O’Grady said the vehicles allegedly overtook other vehicles from the left, crossed over double lines and sped.
She said the vehicles involved were a 2011 blue Skoda station wagon, a 2008 black Jeep Wrangler, a blue Mini Cooper sedan and a green Volkswagen Jetta sedan.
Investigators have been told the drivers involved were communicating with each other with portable two-way radios, telling each other when to overtake and if there were any police in the area.
Ballarat Highway Patrol members intercepted the driver of the Skoda, an Oakleigh East man, 26.
He is expected to be charged on summons with dangerous driving and other traffic offences.
