Mr Joyce was last night refusing to discuss his personal opinion on any of the 60-plus ideas he has released in a discussion document, the most controversial being raising the driving age from 15 to 17.
Other ideas include extending the learner licence period, reducing the blood alcohol limits or increasing penalties for drink driving, more speed cameras backed by stiff fines, changes to the give way rule for turning traffic, improvements to roads and more median barriers.
Mr Joyce said he didn't intend implementing all the suggestions.
"The purpose of this review is to have a public debate about which are the most likely to make an impact and the most necessary to adopt," he said, emphasising that public acceptance for any changes was important.
Immediate reactions came from:
* Federated Farmers, which said raising the driving age would affect farming families which had limited travel options;
* The Automobile Association, which didn't think simply raising the age would address lack of driver training. "If you did raise the minimum driving age all you are really doing is killing them a year later" said AA spokesman Mike Noon.
* The Alcohol Advisory Council said it supported reducing the blood alcohol limits, which were high by international standards. "International experience shows that a reduction in the blood alcohol level is likely to bring down mean alcohol levels amongst all drivers, including the 'hard core'," the council said.
