Quotes attributable to Road Policing Operations and Investigations Division Superintendent, John Fitzpatrick:
"Speeding drivers on Melbourne's major freeways and highways pose a significant risk to themselves and other road users - particularly those choosing to travel at excessively high speeds.
"It is evident these drivers have a blatant disregard for the road rules and the safety of others.
"State Highway Patrol will continue to run operations like Hammerhead to ensure we are catching and removing these dangerous drivers from our roads.
"Speeding continues to be a major contributor in serious injury and fatal collisions, and we are seeing that play out again in this year's road trauma.
"The likelihood of being involved in a collision increases significantly when travelling at higher speeds. We need people to slow down and adhere to the speed limits, and those that do not will be held to account".
