ADI PART 3 TRAINING - MERGE IN TURN
Merge in turn is a simple but essential driving rule that keeps traffic moving safely and efficiently when lanes are reduced, such as during roadworks or lane closures. Instead of drivers racing ahead or trying to push in at the last second, each vehicle takes turns joining the single lane—just like a zip closing. This method, often called “zip merging,” is proven to reduce congestion, minimise frustration, and lower the risk of accidents caused by sudden braking or aggressive lane changes.
Many people mistakenly think merging early is more polite, but using both lanes fully and then merging in turn actually keeps traffic flowing more smoothly and prevents long tailbacks. It’s about cooperation, not competition. By staying calm, maintaining a steady speed, and allowing one car from each lane to merge at a time, drivers can create a safer and more predictable environment for everyone on the road.
Next time you see a lane closure, remember: don’t panic, don’t rush—just merge in turn. A little patience and courtesy go a long way in making journeys quicker and far less stressful for all.
