Why is it not allowed to overtake on the right side?

[Tamara]

There are two main reasons why overtaking on the right side is prohibited. Additional details are as follows: 1. Left-hand drive vehicles: In China, we drive right-hand traffic with left-hand drive vehicles. Overtaking from the left provides better forward visibility for the driver. Overtaking on the right creates larger blind spots, as the vehicle must first move into the right lane to fully assess safety conditions, increasing accident risks. 2. Fast lane: The left lane is generally the fast lane, while the right lane is for slower traffic. Since overtaking requires acceleration, attempting this from the right side increases chances of being blocked by slower vehicles and raises accident probability. Left-side overtaking follows natural traffic flow. 3. Proper overtaking procedure: Check left mirror, signal left turn, confirm safety, accelerate into left lane, pass preceding vehicle, then merge back to right lane to complete the maneuver.
