The move could encourage those who had their restricted licences for a long time to sit the full licence test, he said.
"There are people who have had their restricted licence 20-plus years and never got their full. How many people would want an R plate on the back of their car for the rest of their life? Not many I wouldn't think." he said.
April McRae, of April's Driving School, said she would support anything that encouraged people to become better drivers.
"I see some shocking drivers on the road. I wouldn't say that about the ones I'm teaching because they're still learning but yes there are some bad ones out there."
An Automobile Association (AA) spokesperson supported the move and said R plates for restricted license-holders was another tool to help reduce the number of accidents involving young, inexperienced drivers.
AA motoring affairs general manager, Mike Noon, said young drivers were six to seven times more likely to have a crash than older, more experienced drivers.
"R plates could avoid driver peer pressure and possible incidences of alcohol-related driving and driving late at night and that sort of thing," he said. "People would know they're not supposed to carry passengers and this could be a way to reinforce that."
"It may not be cool to display them but R plates would better identify inexperienced drivers and show others they haven't got their full licence yet."
Senior Sergeant Ian Campion said the drivers who were most at risk were the ones who were "inexperienced".
"I would support certainly this move as a way to identify less experienced drivers ... and it's really important we do what we can to get these people through to their mid-20s when the risk decreases."
In 2011 there were 12 fatal crashes and one involved a restricted licence holder.
Currently, there are 2693 Class 1 Restricted licence holders in the Bay of Plenty.
