We all recognize the jerks on the road when it comes time to merge.
A construction project has reduced the number of open lanes, and these motorists have the audacity to pull forward off the line and cut into the remaining open lane amid a chorus of honking, shouting and gesturing .
However, they are the ones that merge correctly, according to the Colorado Department of Transportation.
The department has been promoting the “zipper method” of merging when traffic is particularly congested for a decade. Authorities recommend this late-merger strategy in which drivers use the entire roadway and take turns to switch from the closed lane to the open lane as the road narrows.

In the event of heavy congestion, this strategy reduces delays by up to 35%, depending on the department.
When people merge early, they create a more serious backup because they leave a lane unused, CDOT spokesman Bob Wilson said.
Despite the department’s education efforts for a decade, people still merge early, although early merger in a small footprint has less of a negative impact.
“I don’t know what it will take to get people on board,” Wilson said. “Changing people’s driving behaviors is a long process. “
