Hundreds of intersections - including 500 in Auckland - need modifications to make them safer ahead of the reversal of the left-turning traffic rule in five weeks.
Auckland Transport has surveyed 15,000 intersections throughout the region before the March 25 rule change, which is expected to prove a big challenge for many drivers already hazy about who has the right of way when turning.
Chief executive David Warburton says the modifications will mainly include new road markings, signs and timing adjustments to traffic signals. Work will start in the next fortnight.
