Reducing the default speed limit from 100kmh to 80khm and expanding 30kmh zones will also be discussed at the Towards Zero Road Safety Summit next month.
Among them is a drink drive limit of 0.02, more than half the current 0.05 limit. That would mean just one mid-strength beer would generally put someone over the limit.
Another policy on the table is to remove warning signs for mobile speed cameras so motorists think their speed could be checked at any time.
Using average speed cameras to measure a car driver’s speed over a longer period of time will also be considered.
