Rightmost three lanes refer to any one of the three lanes on the right. For example, if there are four lanes in total, counting from right to left, suppose the fourth lane, the leftmost lane, is marked for left turns only, meaning vehicles in this lane 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 any of the rightmost three lanes. More details are as follows: 1. Definition: The STT intelligent fuel-saving system is a system that controls engine start and stop. STT is short for STOP&START. 2. Principle: By installing an enhanced motor with idle start-stop function on a traditional engine, the system allows the engine to completely shut off when the vehicle meets idle stop conditions. 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 for seamless transition, thereby significantly reducing fuel consumption and exhaust emissions.

After driving for so many years, I've noticed that many beginners get confused by the navigation's 'Xth lane from the right'. Specifically, 'the third lane from the right' is counted from the far-right curb lane (including the emergency lane) towards the left, based on the direction of travel. For example, on a six-lane highway, counting from right to left: Lane 1 is the emergency lane (do not drive here!), Lane 2 is the regular far-right lane, and Lane 3 is where you should be. Important reminder: Never mistake the emergency lane for the first lane and occupy it!

Once on a long-distance drive, the navigation suddenly said 'Please keep to the right three lanes.' I immediately glanced at the rearview mirror: first confirming it was a four-lane main road, with the leftmost lane (L1) closest to the green belt. Thus, the right-side numbering should be reversed—the lane next to the curb is R1 (bus lane), next to it is R2, and R3 is actually closer to the central divider. In actual driving, don't rigidly memorize numbers; instead, combine them with road arrows and traffic flow directions. For example, R3 is often a straight-through lane that also allows left turns.

Last night, I helped my neighbor understand the navigation prompt. She panicked and turned on the hazard lights when she saw 'keep right in three lanes.' I told her a simple method: first, drive in the far-right lane without crossing the emergency lane—that's the rightmost lane (lane 1). Move one lane to the left to be in lane 2, and another lane to the left for lane 3. But never force a lane change on the highway! Actually, when the navigation says this, it usually means there's a fork within the next 3 kilometers. The safest approach is to occupy a middle-to-right position in advance.

During the driving test for Subject 3, the instructor taught lane numbering techniques. For example, on an eight-lane bidirectional road, lanes are numbered from right to left: Right 1 is the bicycle lane (don't cross the line), Right 2 is the slow lane, Right 3 is the travel lane, and Right 4 is the fast lane. Therefore, 'the third lane on the right' specifically refers to the Right 3 position. But be careful: during morning rush hour, Right 3 might become a bus-only lane! Once I followed the navigation and took Right 3, only to get a ticket. Later, I learned to check the traffic signs for the current time period.

Remember last year during heavy rain while driving, the navigation suddenly announced ‘Please take the right three lanes,’ but the water made it impossible to see the markings. My experience is: first, look at the overhead signs. If it’s a three-exit fork, ‘right three lanes’ often refers to the lane leading to the middle exit; if it’s a regular section, find a position slightly to the right but not the outermost in the traffic flow. When truly uncertain, following the majority of local license plates is the safest bet—they know the lane divisions best.
