When both left-turn and straight-ahead signals are green, vehicles in the left-turn lane cannot proceed straight directly, otherwise they will incur penalty points and fines. Some lanes have both left-turn and straight-ahead markings, in which case drivers may turn left or go straight while obeying the traffic signals. Below is an introduction to common road signage knowledge: One-way street: Indicates that the entire road only permits vehicles to travel in one direction. For example, if a certain road section only allows travel from south to north, but a driver proceeds from north to south, this constitutes driving against traffic and will result in penalty points and fines. No long-term parking: Indicates that temporary parking is permitted, such as for passenger pick-up/drop-off or loading/unloading goods.

Having driven for decades, I've seen many accidents caused by going straight in a left-turn lane. Lanes are divided into left-turn, straight, and right-turn for safe traffic diversion. If you go straight in a left-turn lane, the car behind may assume you're turning left. Once you suddenly go straight, you risk colliding with oncoming straight-moving vehicles or being hit from the side—extremely dangerous. Police usually impose fines of 200 to 500 yuan and deduct 2-3 points. The worst part is causing an accident where you're fully liable, leading to costly repairs and medical bills. I recall a news report last year about a young driver who did this, totaling his car and landing in the hospital. Safety first! Always change lanes early for straight driving—don’t cut corners. Check mirrors frequently, observe nearby vehicles, and maintain distance while your route. If the intersection has a long green light, wait patiently for a safe lane change—never take the risk.

From a regulatory perspective, traffic rules clearly stipulate that lanes must be used according to their markings. In most cities, including Beijing and Shanghai, left-turn lanes are exclusively for vehicles making left turns. If you proceed straight in such a lane, you violate the Road Traffic Safety Law by failing to drive in the designated lane, which incurs a fine of at least 200 yuan and may also result in a 2-point penalty. I have personal experience with this—a friend of mine was fined 300 yuan for doing so and deeply regretted it. These laws exist to reduce confusion and prevent collisions or traffic flow blockages. In case of an accident, you would be at fault, and your company might deny the claim, leading to even greater losses. It's advisable to develop the habit of paying attention to road signs and traffic signals at least 50 meters before an intersection. If you find yourself in the wrong lane, it's better to make the left turn and circle back rather than illegally proceeding straight to save time.

When I was a new driver, I foolishly thought about going straight from the left-turn lane. Once, while queuing to go to the supermarket, I got into the wrong lane and thought going straight would be faster. As soon as the light turned green, I stepped on the gas, only to be startled by the loud honking from the cars behind me, breaking out in a cold sweat. Fortunately, I slammed on the brakes in time and avoided an accident, but the roadside guard lectured me for a while. Now I've learned my lesson—I check the route and lane guidance on my phone app in advance, so I don’t panic at the traffic light. If I realize I’m in the wrong lane, I’d rather slowly follow the left turn and find the next intersection to make a U-turn instead of forcing my way through. After driving for a while, I’ve come to understand that such small things aren’t worth the risk. Everyone should take it slow and pay more attention to the directional signs on the sides.

Why do road design experts set up dedicated left-turn lanes? It's to optimize traffic flow, reduce intersection conflicts, and improve efficiency. Left turns and straight movements are different, with significant time differences. Forcing straight movements would disrupt all vehicles, leading to crashes and congestion. I've studied urban traffic, and designers meticulously arrange each lane's function. If you disrupt it, the entire road's smoothness is ruined. I once saw such reckless behavior during rush hour, paralyzing an entire intersection for ten minutes. I advise everyone to pay attention to road signs and follow lane markings for the smoothest flow. If you mistakenly enter the wrong lane, don't panic—stop and wait for the green light before moving to prevent a chain reaction.

Daily driving tips: If you accidentally enter a left-turn lane, don’t panic and go straight. The safest option is to turn left, make a U-turn, or return after turning. When the light turns green, proceed slowly but signal right to avoid blocking traffic. I often use navigation voice reminders, which prompt lane changes 300 meters in advance. Develop a habit: slow down at intersections and check signs carefully; if the green light lasts long, wait patiently in line. If you must go straight, ensure you’re in the correct lane to avoid fines. Simply put, if you make a mistake, adjust your route—don’t rush to save a few seconds.
