The leftmost lane cannot go straight. Consequences of going straight in the leftmost lane: Driving not according to the marked lanes will result in a fine of 200 yuan and 3 demerit points. If the straight signal light is red, it constitutes running a red light. When all lights are green, you may be penalized for not entering the guiding lane in the required direction of travel, or you may not be penalized. Introduction to the leftmost lane: When there are two or more motor vehicle lanes in the same direction on the road, the left lane is the fast lane and the right lane is the slow lane. Vehicles driving in the fast lane should drive at the corresponding prescribed speed. If the prescribed speed of the fast lane is not reached, vehicles should drive in the slow lane. When overtaking the vehicle in front in the slow lane, vehicles can borrow the fast lane.

I really have some experience to share about whether you can go straight in the leftmost lane. Having driven for over a decade, I've encountered similar situations at various intersections. Generally, you need to carefully observe the ground arrows and roadside signs. For instance, some lanes are marked as left-turn only, and you absolutely cannot go straight through them. I remember last year at an intersection downtown, when the arrow indicated both straight and left turns, I proceeded straight. But the very next day on a suburban road, the arrow was for left turns only, and I accidentally went straight, resulting in a 200-yuan fine. Why is this so important? Because if you go straight, you might disrupt traffic flow or collide with left-turning vehicles, especially during rush hours when traffic is heavy. My advice is to slow down a bit before reaching the intersection, check the markings clearly, and then proceed—it's safer and less stressful. Also, pay attention to traffic light changes; don't rush and act recklessly. Rules can vary between cities; for example, larger cities might enforce them more strictly. Gaining more experience will always help.

From a regulatory perspective, whether the leftmost lane allows straight-through driving depends on specific road markings. When driving, I always remember one thing: if there are arrows on the ground indicating straight or straight-left directions, you can proceed; if only left-turn or turning arrows are marked, you must not go straight. Legally speaking, this is a mandatory rule—violations can result in penalty points, fines, and even accidents. For example, at intersections, signs often indicate lane purposes, so you must develop the habit of observing them. From a safety standpoint, making a wrong move could lead to dangerous rear-end collisions. In real life, navigation systems sometimes can't help, so you truly need to rely on your own judgment. Be extra vigilant when driving in bad weather or at night, as poorly reflective signs are easy to miss. In short, the rules are simple but require attention to detail—don't underestimate this.

Safety first is the key, don't misuse the leftmost lane for going straight. I never take that risk, as the car behind might think you're turning left and rear-end you. There are many lessons: I've seen a driver who got fined for mistakenly going straight and then got into a minor accident—it's not worth the risk. Always prepare dozens of meters in advance before driving, clearly observing traffic lights and arrow markings. If unsure about lane usage, prioritize the right lane or slow down to choose. Rainy nights are even more dangerous; when signs are unclear, don't guess—it's better to detour. Ensuring good driving habits is more important than anything else.
