Can I turn left when both the straight and left turn signals are green?

[LuciaDella]

When both the straight and left turn signals are green, vehicles in the left turn lane are allowed to turn left, but they must yield to oncoming straight-moving vehicles. If there is an arrow signal for the lane, turning left is not permitted when the straight arrow is green but the left turn arrow is red. However, vehicles can enter the left turn waiting area. Once the left arrow turns green, vehicles in the lane can proceed with the left turn. Here is some information about turning at traffic lights: According to Article 38 of the 'Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China' (State Council Order No. 405), motor vehicle and non-motor vehicle signal lights indicate: When the green light is on, vehicles are allowed to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles or pedestrians; when the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. Other situations involving a green straight signal and left turns: If the intersection is controlled by a standard circular traffic signal, vehicles can turn left from the left turn lane when the straight signal is green. This is a normal traffic condition and will not result in penalties. However, if the intersection has a left turn arrow signal, turning left is prohibited when the left turn arrow is red. Doing so would be considered running a red light, which is a traffic violation. Vehicles must wait until the left turn arrow turns green before proceeding. At intersections with a left turn waiting area, vehicles can enter the waiting area when the straight signal is green but cannot proceed to turn left through the intersection. Important Notes: At intersections without separate signals for non-motor vehicles and pedestrians, non-motor vehicles and pedestrians should follow the motor vehicle signal indications. When the red light is on, right-turning vehicles may proceed if they do not obstruct the passage of other vehicles or pedestrians.

I've been driving for over a decade and frequently encounter intersections like this. When both the straight-through and left-turn green lights are illuminated simultaneously, you can absolutely make a left turn. This is because the traffic signal is designed this way to allow vehicles to move freely, granting right-of-way to both straight-going and turning vehicles without interference. I've seen many intersections using this dual-green-light setup to reduce waiting time and improve traffic efficiency. However, before turning, I always make it a habit to glance at the rearview mirror and check the opposite direction to ensure no vehicle is suddenly approaching – safety comes first. Also, remember to use your turn signal in advance to indicate your intention to other drivers and avoid minor accidents. This rule is commonly seen on urban arterial roads. In some places where there's only a solid circular green light without separate straight and left-turn signals, you'll need to rely on traffic signs for guidance. In short, when the green light is on, turn confidently without unnecessary hesitation that holds up traffic.

I just got my driver's license not long ago and am still quite unfamiliar with driving. The first time I saw both the straight green light and left-turn green light on simultaneously, I felt a bit nervous and wasn't sure if I could turn left. My instructor taught me that a green light means permission to proceed, including left turns, so now when encountering this situation I decisively make the turn. The key is to combine it with road conditions - for instance during rush hour with heavy traffic, I'll turn more slowly and only proceed after confirming there are no straight-moving vehicles in the opposite lanes. Additionally, some intersections have dedicated left-turn arrow signals, which provide independent control and are safer by avoiding conflicts. As a new driver prone to panic, I recommend checking the intersection signal types in advance to avoid sudden braking during left turns that might cause rear-end collisions. Regularly reviewing road rule pamphlets helps build proficiency through practice, making it much easier next time.

I've seen many traffic rule explanations where a straight green light and a left-turn green light illuminating simultaneously usually indicate that both directions are permitted, so you can definitely make a left turn. The logic of traffic signals is that green means free movement, unlike red or yellow lights which impose restrictions. For instance, on major roads, this setup helps reduce congestion by eliminating the need for drivers to wait for a dedicated left-turn signal. However, it's important to note that there might be slight variations in different regions—some small towns may use a simple green light for all movements, while larger cities often have more detailed signal phases. When turning, I make sure to maintain a clear field of vision, proceed at a reduced speed, and avoid misjudgment risks. Simply put, when the light is green, just go—don't overcomplicate it.

Last week, I drove to the supermarket. At an intersection, both the straight-through and left-turn green lights were on, so I smoothly turned left into the parking lot without any issues. This traffic light design saves time and ensures smooth vehicle turns. I remember mistakenly thinking only one light mattered before, but now I understand that synchronized green lights indicate a unified instruction to turn. I’ve also encountered rainy conditions where the road was slippery—I deliberately reduced speed while turning and turned on the wipers for better visibility. Such dual-green-light intersections are common in commercial areas. With more experience, it becomes habitual to find the right moment to merge into traffic flow.

Having driven for years, it's common knowledge that left turns are allowed on a steady green light, but safety is always the priority. Before turning, I make sure oncoming traffic has stopped and the crosswalk is clear to prevent accidents. The signal rule is simple: green means go, including left turns; if there's a dedicated turn arrow, follow that instead. I maintain a reasonable speed when turning, avoiding sudden acceleration that could risk hitting pedestrians or running a red. Intersections are accident-prone, so practicing anticipation skills is crucial—like observing signal timing patterns. I habitually roll down windows to listen for external sounds, which helps assess road conditions—a surprisingly effective trick. In short, turn when rules permit, but safety lies in the details.
