Increasing numbers of people are grasping the new give-way rules and no major accidents have occurred that can be directly blamed on the law change.
Despite fears of carnage and confusion when the rules changed on March 25, the New Zealand Transport Agency says a survey shows 90 per cent of people know the correct give- way rules, a big increase on several months ago.
Acting chief executive Stephen Town said most people were being patient and cautious.
"A few very vocal critics were predicting that drivers wouldn't cope with the changes, and that chaos on the roads would result.
"We're pleased that New Zealand has proved them wrong."
