Murphy visited Taieri College, in Mosgiel, and South Otago High School in Balclutha as part of a nationwide tour to teach pupils about the importance of driver education.
The aim of the initiative is to bring the road safety message to schools in an attempt to curb unnecessary road accidents involving teenagers.
"It is a passion of mine to provide some information [about driving] to raise awareness," he said.
The driving age in New Zealand was too low, and 15-year-olds were not given enough training to be given a licence, he said.
"The bulk of young drivers are vastly ill-equipped to be on the road."
Murphy, who is working with the Motor Trade Association (MTA) on his education tour, believed simple programmes could be put in place to save lives.
"The fact that we have the youngest driving age in the world and the worst rate of deaths [from traffic accidents] per capita says we need a change."
MTA web and communications manager Ana Zandi said a third of all fatal crashes on New Zealand roads involved a driver between the ages of 15 and 24.
"I think more education for young drivers would be good. We need to extend the process, rather than offer them a short condensed time to train," Ms Zandi said.
At South Otago High School, one pupil asked Murphy what he would do to make a road car safer.
"Bolting in roll cages into a road car would never get through, but it would definitely make the car a lot safer. Also having a seat shaped to fit the driver would also help, but road car seats are designed so anyone can sit in them," he replied.
Pupil Jo Harrex said: "The talk was really good. Some of the statistics were a bit freaky but it's good information to know."
Murphy also talked to the Students Against Driving Drunk committee. Member Bryn Pearson said it was good to have the chance to talk with Murphy in a smaller group.
"There's been a lot of changes in driving over the years and it's good to hear from someone as experienced in driving as Murph."
Murphy said his most important advice to young people was they get some professional driver training.
"Most people learn how to drive from their parents. They may have a lot of experience but it was a long time ago that their parents learned how to drive. A professional instructor knows lots of little bits of information that could save lives."
