Last minute merges on highways are often blamed on causing road rage but now some states encourage drivers to do it when two lanes become one.

It's called the zipper merge.

That's when you wait until the last moment to join a single lane of traffic before construction zones then take turns with folks in the other lane.

Several studies point to benefits of zipper merging, including 50-percent shorter lines and reduced speeds around construction workers.

However, transportation officials in some states aren't convinced.

“We don't want those people to cut in at the very last second. Not only can it lead to road rage incidents but again it can lead to sudden breaking which can cause a direct collision,” Mark Dinger with California Department of Transportation.
