Changes will be made at a number of intersections around Wellington over the next few weeks in preparation for new give way road rules.
The right-hand law peculiar to this country will be brought into line with the rest of the world on March 25.
New Zealand adopted the current rule in 1977 from the Australian state of Victoria where it was introduced to assist trams on Melbourne streets. Victoria changed back in 1993, resulting in a drop in intersection crashes.
It has been estimated that a return here to alignment with other countries will reduce the cost of accidents by $17 million a year.
Pedestrian safety at New Zealand intersections is also expected to improve vastly when drivers turning left are able to go first, rather than giving way to traffic turning right.
