The Transport Agency is asking for public submissions on proposed changes to give-way road rules.
At present, vehicles turning left must give way to right-turning traffic.
Under the planned change that would be reversed, giving left-turning vehicles the right of way.
Changes are also planned for T-intersections.
The public has until 24 June to make submissions.
Transport Minister Steven Joyce says research shows that changing the rules could reduce crashes at intersections by 7%.
Any changes would come into force early next year.
