Zip It!

You could also call the zipper method “after you,” because it involves letting the driver next to you merge in front. Like the teeth of a zipper, vehicles merge alternately one after the other. Studies have shown that the zipper method can make traffic flow 40 per cent more efficiently. It uses more roadway and, consequently, moves us faster. Despite these facts, use of the zipper method is not as common as it logically should be. Note: if a lane closure has caused an accident (or similar calamity), forget the zipper method, move to the right immediately to allow for emergency vehicles to pass.
