You can make a left turn on the auxiliary lane when there is no prohibition sign, but you must not hinder the passage of other vehicles and pedestrians. Precautions for merging from the auxiliary lane to the main lane: When changing lanes to enter the main lane, the driver needs to turn on the turn signal in advance to alert passing vehicles, pay attention to the traffic conditions behind the main lane, and observe the traffic situation behind when merging from the auxiliary lane to the main lane. Only merge slowly when ensuring there are no vehicles behind. Blind spots generally exist in rearview mirrors. During daily driving, you can check through the interior rearview mirror or by turning your head directly to ensure the safety of lane changes and avoid abnormalities during the process that may cause traffic accidents. When merging into the main lane, do not turn the steering wheel too much, leaving some buffer space for the following vehicles: During lane changes, control the steering wheel's turning range to avoid large steering movements, which can reduce comfort. Since vehicles on the main lane move faster, excessive steering may cause the following vehicle to react too late, leading to traffic accidents.

I often encounter similar issues while driving. Generally speaking, whether you can make a left turn from an auxiliary lane depends on the specific situation. Auxiliary lanes are usually secondary lanes next to the main road, such as those at highway exits or urban expressway auxiliary lanes. Some places have dedicated traffic signals allowing left turns, but others may prohibit it to prevent accidents. I once tried making a left turn at an intersection and found no signs, so following the traffic signal was the safest option. If there’s a 'No Left Turn' sign at the intersection, forcing a turn could result in a fine or cause an accident. It’s advisable to pay close attention to traffic signs and signals while driving. If unsure, detour via the main road—safety comes first. Paying attention to these details regularly can reduce trouble and help develop good driving habits.

From a traffic regulation perspective, the feasibility of left turns from auxiliary lanes depends on local laws and setup. Auxiliary lanes are designed to facilitate traffic flow and may occasionally permit left turns if clearly marked with permission signs or signals, though it's generally discouraged to avoid disrupting main road traffic. For instance, urban auxiliary lane left turns require verifying dedicated turn lanes and signal status, avoiding prohibited zones. Key factors are on-site indicators: signs, pavement arrows, or signals directly determine permissibility. I recommend developing a habit of checking, stopping to observe when necessary, or consulting traffic experts. Remember that illegal left turns are not only hazardous but may also incur penalty points, fines, and affect insurance discounts—always prioritize compliance with regulations while driving.

Over the years, I've driven to quite a few places, and I can tell you that making left turns from auxiliary lanes shouldn't be taken lightly. Auxiliary lanes are often points of divergence or merging, and turning left there can easily lead to collisions with through traffic, unless there's clear permission like a green arrow signal. Last time I was discussing this with a friend by the side of an auxiliary lane, he mentioned getting ticketed for an illegal left turn at night. So my advice is to look carefully before you act, especially paying attention to safety signs at intersections. Don't risk it just to save time—finding a safe detour is always the smarter move.

When driving with family, I pay extra attention to left turns from auxiliary lanes as they directly impact passenger safety. Auxiliary lanes are often narrow and busy, making left turns high-risk, and in most cases, a dedicated turning lane is required for legal operation. For example, if you encounter a 'No Left Turn' sign, don't force it to avoid sharp turns that might scare the children. I always slow down first to observe traffic signals and signs; if unsure, I wait for a safe opportunity or choose a main road turning point. Regular car maintenance should also include checking turn signal functionality to ensure they work in critical moments, as family travel safety is always the top priority.
