![]() The bottom line is to merge when it is safe to do so. When traffic is moving at highway speeds and there are no backups, it makes sense to move sooner to the lane that will remain open through construction. Don't worry about being "Minnesota nice." When traffic is heavy and slow, it is much safer for motorists to remain in their current lane until the point where traffic can orderly take turns merging. Then take turns with other drivers to safely and smoothly ease into the remaining lane. Yes!

When most drivers see the first “lane closed ahead” sign in a work zone, they slow too quickly and move to the lane that will continue through the construction area.
