What does the right three lanes mean?

[Mitch]

The right three lanes refer to any one of the three lanes on the right. For example, if there are four lanes in total, counting from the right to the left, suppose the fourth lane, the leftmost lane, is marked for left turns only, meaning that once you enter this lane, you are only allowed to turn left, not go straight or turn right. Lanes one to three can all go straight. When you need to go straight, the software will announce: 'Please take the right three lanes.' Here is some additional information: 1. Abbreviation: STT stands for STOP&START. 2. STT Intelligent Fuel-saving System: It is a system that controls the starting and stopping of the engine. By installing an enhanced motor with idle start-stop functionality in a traditional engine, the system allows the engine to completely shut off when the vehicle meets the conditions for idle stopping. When the vehicle needs to start moving again, the idle start-stop motor system quickly responds to the driver's start command, rapidly starting the engine and seamlessly engaging, thereby significantly reducing fuel consumption and exhaust emissions.
