Merge Like a Zipper - Driving T Shirt
Right lane closed in 1,500 feet. Half the traffic gets over at the first sign and sits in a line that runs back to the last exit. The other half drives the open lane up to the cones, and the first half takes it personally. State transportation departments have been asking for the same fix for years: use both lanes to the end, then alternate at the merge point. It shortens the backup. Nobody at the cones has read it. A funny driving shirt for the driver who lets exactly one car in, then closes up so the next one has to wait. The sign is still there. So is the pickup that let nobody in.
THE FINE PRINT
MERGE LIKE and a huge A ZIPPER across the top, ONE CAR AT A TIME below, all three in cracked white capitals, then a small public service announcement line. Between them a road narrows to one lane, white cars on the left and yellow on the right, alternating into the single lane behind a zipper pull.

ASKING FOR A FRIEND
Is zipper merging legal?
In most places, yes, and several state transportation departments, Minnesota's among them, recommend it: keep to your own line until the merge point, then take turns. Using both sides all the way to the cones is part of the method. Closing the gap so nobody can get in front of you is the move that earns the honking.
Why do traffic jams happen?
Mostly because there are more cars than space, and small disturbances grow: one driver brakes, the driver behind brakes harder, and the slowdown travels backward for miles after its cause is gone. A closure adds a second problem when half the drivers merge early and leave half the highway empty. Taking turns at the merge point keeps both lines moving.
Why do people cut in line?
Usually because they have decided the wait does not apply to them, and some honestly never noticed there was a line. On the highway it is murkier: a driver who rides the open side to the merge point is following the instructions, not cutting. The early mergers just got in line a mile too soon.
