What are the rules for two lanes merging into one lane?

[McGage]

According to Article 53, Paragraph 3 of the 'Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China': At intersections or road sections where lanes are reduced, if motor vehicles ahead are stopped in queues or moving slowly, vehicles from each lane shall take turns to enter the reduced lane alternately, one vehicle per lane at a time. Below is an introduction to traffic signals: 1. Function of traffic signals: Traffic signals are lights that direct traffic flow, typically consisting of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to proceed, and a yellow light serves as a warning. 2. Classification of traffic signals: Traffic signals are categorized into motor vehicle signals, non-motor vehicle signals, pedestrian crossing signals, directional indicator signals (arrow signals), lane signals, flashing warning signals, and level crossing signals for roads and railways.

When two lanes merge into one, the general rule is to alternate, much like a zipper, with vehicles from the left and right taking turns to enter the single lane. From my years of driving experience, it's best to slow down in advance, use turn signals, maintain a safe distance, and avoid competing for space. Forcing your way in can easily lead to rear-end collisions, congestion, or even minor accidents. For instance, at highway exits or construction zones, it's best to proceed in order to ensure both safety and efficiency. I believe patience is key—observe the movements of vehicles on both sides and confirm there's a gap before acting. Sometimes, road signs will indicate who has the right of way, and it's crucial to follow them. The overall principle is to minimize risk and allow all vehicles to pass smoothly.

I encounter two lanes merging into one during my daily commute, such as at busy intersections. Last week, I experienced this on a bridge where everyone followed the zipper merge rule, and the process went smoothly. Personally, I believe the most important thing is to prepare in advance and avoid hasty maneuvers: slow down to an appropriate speed, signal with your turn indicator, and take turns merging with drivers from the left and right lanes. If someone doesn’t follow the rules and cuts in front, the entire lane can get stuck—I’ve seen this cause minor traffic jams a few times. When changing lanes, I recommend checking your mirrors and blind spots carefully to ensure safety. This rule not only saves time but also fosters road etiquette.

The basic rule for merging from two lanes into one is alternate merging, which requires vehicles to take turns proceeding to prevent accidents. Drivers should slow down to yield, use turn signals, and merge alternately from both lanes. Forcing a lane change is a traffic violation that may result in fines or collisions. I believe familiarizing oneself with these rules can enhance overall safety levels.

As a new driver, changing lanes made me nervous. When merging from two lanes into one, it's a zipper merge where cars from both sides alternate. I think the key steps are: slow down, signal, observe the traffic in the other lane, and if the other driver yields or waits, take turns moving forward. Avoid impatience and don't force your way in, as that can lead to mistakes. Practice more on smooth road sections to familiarize yourself with the rules and reduce panic. Remember safety comes first, and cooperation makes the process easier.
