Research by Victoria's Transport Accident Commission (TAC) has revealed a change in attitudes towards speeding.
Since 2001, the proportion of those who say they never speed has double from seven percent to 15 percent.
At the same time, those who say they speed all or most of the time has almost halved from 23 percent to 12 percent.
"Speeding is illegal, it is dangerous and it is one of the biggest killers on our roads so it makes absolutely no sense why anyone would think it's OK to do it," TAC Acting CEO Claire Amies said.
The release of the results coincides with the launch of the Commission's new advertising campaign, titled Reconstruction.
The aim of the campaign is to show drivers that a speed reduction of 5km/h can limit the severity of pedestrian injuries after a crash.
The research, which was part of the TAC's first quarterly research activity for 2012, was conducted by phone with 900 Victorian licence holders.
"Every day at the TAC we work with thousands of road trauma victims and their families who have suffered injuries from preventable crashes," Ms Amies said.
"These people and their struggles should serve as reminders to the rest of our community of the need to stay within the speed limit."
