Which lane should you choose when driving on a road with lane traffic signals?

[VanParker]

On a road with lane traffic signals, you should choose the lane indicated by a green arrow. Drive in the lane to which the arrow is pointing. Legal provisions: When a motor vehicle passes through an intersection controlled by traffic signals, it shall proceed in accordance with the following provisions: at an intersection with marked guide lanes, enter the guide lane according to the intended direction of travel; motor vehicles already within the intersection preparing to enter a roundabout have the right of way; when turning left, turn from the left side near the center point of the intersection. Turn signals must be activated when turning, and low beams must be used at night. Function of traffic signals: Traffic signals are lights that direct traffic flow, generally consisting of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to proceed, and a yellow light serves as a warning.

In my experience on such road sections, I always choose the lane with a green arrow signal and absolutely avoid those marked with a red cross. These traffic signals serve as real-time traffic controllers—ignoring them is extremely dangerous and can easily lead to collisions or rear-end accidents. When I first started driving, I witnessed someone forcibly entering a lane with a red cross, only to be fined by the police and spend a fortune on repairs. Lane signals can change frequently, especially during peak hours when they may flash repeatedly, so it's crucial to slow down and observe carefully rather than rushing. Additionally, these sections often appear near highway entrances/exits or busy urban intersections, where a red signal indicates the lane is currently occupied or about to close. Remember, obeying signals isn't just for your own safety but also protects others—never take the risk.

As a working professional who drives every day, choosing the green arrow lanes on these road sections can save time. For example, during the morning rush hour, traffic signals often change, and a previously empty lane might suddenly display a red cross, so I observe in advance and choose the lane that's open. Typically, a green light indicates an open fast lane, while a red cross means it's either being cleared or congested—avoid entering. Once, I chose the wrong lane and ended up stuck for ten minutes, but I learned my lesson and now always check the signal patterns in advance, combining them with actual road conditions. The design of lane signals is meant to optimize traffic flow, and choosing the right one can avoid frequent braking and reduce fuel consumption. Remember not to be impatient; ensure safety while improving efficiency.

Lane selection must strictly follow signal indications—only enter lanes marked with a green arrow. This is a core traffic rule: a red cross signal prohibits entry into that lane, and violation constitutes a traffic offense. For example, entering a variable lane section against a red cross may result in photo enforcement fines or penalty points. Signal changes are based on real-time traffic flow; choosing the wrong lane increases accident risks, potentially making you fully liable. Obeying signals is the simplest, most effective, and safest approach.
