What are the rules for merging from three lanes into two lanes?

Slow down and proceed with normal driving. Considerations for lane changing include: 1. Situations where lane changes are not allowed: When encountering situations where lane changes are not permitted during driving, follow the traffic flow. While continuing with the traffic flow, pay special attention to other traffic conditions and cautiously return to the original planned route. 2. Avoiding obstacles: When changing lanes, do so appropriately in advance; prevent vehicles in adjacent lanes from affecting the lane change, which could lead to braking, stopping, or forcing a lane change, potentially causing a collision. 3. During lane changes: Avoid abruptly turning the steering wheel into the adjacent lane to prevent collisions with suddenly appearing vehicles or skidding due to slippery road surfaces. Lane changes should not be too slow; driving long distances over lane markings can affect other vehicles. Generally, lane changes should be completed within 50-60 meters. Each lane change should only be to an adjacent lane; if changing to a lane beyond the adjacent one, first change to the adjacent lane, drive for a while, then change to the next lane. Do not change more than two lanes consecutively. In sections where lane dividers are solid or dashed, vehicles on the solid line side are strictly prohibited from changing lanes. 4. Dedicated turning lanes: When turning at an intersection, observe road signs or directional arrows on the road. Before entering the solid line area, change lanes according to the directional arrows based on the chosen route. For a right turn, change to the right lane to enter the right-turn dedicated lane; for a left turn, change to the left lane to enter the left-turn dedicated lane.
As a veteran driver with over 20 years of experience, I've encountered numerous situations where three lanes merge into two, and I understand that the key rule is the 'zipper merge' principle. This means vehicles from both lanes should take turns alternately, like the teeth of a zipper—one from the left, then one from the right. In practice, I always signal my intentions early with turn indicators, maintain a safe following distance, and monitor traffic flow through my rearview mirrors. Many drivers cause congestion or even minor collisions by rushing to cut in; my advice is to stay calm and wait patiently for your turn. In adverse weather like heavy rain, it's crucial to reduce speed further, as wet roads increase the risk of losing control. I also recommend that new drivers practice this scenario more often in urban areas to avoid panic on highways. Developing good habits not only enhances safety but also saves time, making every journey smoother.
As a complete novice just starting to learn driving, I was super nervous when first encountering a three-lane merging into two-lane situation. My instructor taught me the zipper merge rule: let one car from each lane take turns merging into the narrower lane. I need to remember to slow down first, use turn signals, and avoid cutting in. Common mistakes like ignoring road signs or failing to check mirrors often lead to rear-end collisions. Personally, I find this much harder than straight driving because you must monitor vehicles on both sides; but keeping a one-car distance makes it much safer. During rainy days when roads are slippery, I control speed more carefully. Through repeated practice, I can now confidently say I've mastered the basics - the key is simply following the alternating rule and minimizing horn use to avoid conflicts.
