What is a good rule to follow when merging traffic?

Merging like a zip is a key principle for safe and effective merging in traffic. This method involves allowing vehicles to merge in a way that resembles the interlocking teeth of a zipper; that is, cars take turns merging smoothly into the lane. This helps maintain a steady flow of traffic and minimizes disruptions.

By merging in this manner, drivers can adjust their speed to match that of the traffic in the lane they are entering, which reduces the risk of collisions and helps maintain a consistent flow. Additionally, this technique aids in promoting cooperative driving behavior, where drivers are considerate of one another, leading to a safer and more pleasant driving experience for everyone on the road.

Other approaches, such as merging abruptly or at high speed, can create hazards, increase the risk of accidents, or lead to traffic congestion. Choosing to merge last can also be disruptive and can potentially prevent an orderly merging process, further illustrating the importance of the zip merge technique.
