When is zipping allowed on the road?

Zipping, or the practice of merging vehicles efficiently when a lane ends, is specifically allowed during situations of lane reduction. This typically occurs to facilitate the smooth flow of traffic and to prevent congestion that can be caused by abrupt lane changes. When drivers are aware that a lane is ending, they are encouraged to alternate merges, allowing cars from both lanes to enter the remaining lane in a fair manner.

This practice is designed not only to enhance traffic flow but also to promote safety by minimizing the risk of accidents that can arise from sudden lane changes. In addition, it helps reduce the stress of merging for drivers, as it allows for a coordinated approach to lane closures.

Therefore, zipping is permissible when there is a clear indication of a lane reduction, aligning with traffic management strategies that prioritize efficiency and safety on the road. In contrast, other choices do not taken the specific context of lane reductions into account, which is crucial for the proper application of zipping.
