What is advised to ensure a successful merge at a congested merge point?

To ensure a successful merge at a congested merge point, it is advised to alternate vehicles from both lanes. This method promotes a smoother flow of traffic, allowing vehicles to move safely and efficiently into the merged area. By letting one vehicle from one lane merge and then one from the adjacent lane, drivers create a fair system that helps prevent bottlenecks and reduces the risk of collisions. This strategy encourages cooperation among drivers and optimizes the use of available road space.

Other options may be less effective because they either cause unnecessary delays or can lead to confusion and frustration among drivers. For example, using only one lane might prevent efficient merging and lead to backups. Stopping until space opens can cause further congestion as it disrupts the flow of merging traffic. Entering slowly regardless of traffic may result in unpredictable behaviors that can be dangerous in fast-paced environments. Thus, alternating vehicles not only enhances safety but also contributes to overall traffic harmony.
