How to Define the Completion of a Left Turn?
3 Answers
There is no precise definition in traffic regulations for the completion of a left turn, only that when there is no traffic command, left-turning vehicles must yield to straight-going vehicles. If a straight-going vehicle does not slow down or accelerates when seeing a left-turning vehicle passing, the straight-going vehicle will bear the main responsibility for any accident.
In my opinion, the key to defining the completion of a left turn lies in whether the vehicle has resumed straight-line driving. Simply put, a turn is considered complete when your car has fully entered the new road, the steering wheel is mostly straightened, and you begin to proceed at normal straight-driving speed. For example, at an intersection, if you turn from the left lane into the left lane of another road, once your wheels cross the center line of the lane without any turning tendency, the turn signal should also be turned off—this marks a safe completion. This standard is crucial because it helps avoid sideswipes or rear-end collisions. Over my years of driving, I've noticed that beginners often hesitate during turns—slowing down while turning but needing to gradually accelerate back to normal speed afterward. Remember, on wet or slippery roads like during rain, you should confirm the turn completion point earlier to prevent skidding. Don't overlook details: in congested urban areas, after completing a left turn, you must immediately watch for pedestrians or bicycles and maintain lane centering to truly finish the maneuver.
Defining the completion of a left turn is actually quite simple: when your vehicle has completely exited the curve, the wheels are aligned with the new direction, the speed stabilizes, and the turn signal automatically cancels, it's done. I've driven many long-distance trips on the road and often encounter friends asking about this. I usually suggest focusing on two points: first, the vehicle's position—when the front of the car is no longer turning and is fully centered in the lane of the new road ahead; second, the feeling—when there's no torque on the steering wheel, and you naturally relax. This helps reduce the risk of sudden braking or losing control. After completing the turn, remember to glance at the rearview mirror to confirm safety, as pedestrians might suddenly appear at some intersections. Developing the habit of slowing down slightly before finishing the turn and gradually accelerating afterward is especially useful for beginners. In urban driving, if the traffic light changes, complete the turn more decisively to avoid blocking vehicles behind. Safety first—with more practice, it will become smoother.
