Turns, Lanes, Passing & MergingStandalone practice
Slow traffic fills both lanes approaching a signed zipper-merge lane reduction. How should drivers merge at the reduction point?
Four cars face east in two queues before a coned lane reduction. Only the leading car in the continuing lane is blue; the other three are silver. No priority route, order badge or actor letter appears.
Correct answer: Use both lanes to the merge point, then take turns.
Why
In a signed zipper merge, use both lanes up to the lane reduction and take alternating turns into the continuing lane. Slow, cooperate and leave a safe gap. Follow flaggers and signs if they give specific directions.
