Help us bring zipper merging to Colorado [Video]

DENVER — Why is it so hard for drivers in Colorado to zipper merge?

“It does talk about merging, but I don’t think it specifically mentions the zipper merge,” Driving instructor Jake Dinwiddie said.

As a senior lead instructor for DriveSafe Driving School in Highlands Ranch, Dinwiddie teaches the zipper merge to students, even if it not in the handbook.
