Passing target: 7 correct signs and 18 correct rules
Signs at a work zone call for a late, or zipper, merge. Traffic is slow. How should drivers merge?
Slow traffic occupies two lanes before a coned right-lane closure. Blue car A leads the upper lane. Silver car B leads the lower lane. Two unlabelled silver cars trail them. The card identifies backed-up traffic at a zipper merge; no merge order or route is shown.
Correct answer: Use both lanes to the merge point, then take turns.
Why
Follow the work-zone signs. In the stated signed zipper merge, use both available lanes to the merge point and take turns joining the open lane. Maintain safe spacing and avoid blocking or aggressive competition. Other layouts can require a different merge point.
