Can You Drive Over the Left Turn Guide Line?

[EloiseDella]

Before entering the left turn waiting area: When both the straight and left turn signals are red, vehicles must not enter the left turn waiting area and should wait behind the stop line; otherwise, it will be considered running a red light, which is a traffic violation. Left-turning vehicles are also not allowed to enter the left turn waiting area from the straight lane, as this will be penalized for violating traffic signs and markings. When the straight signal turns green, even if the left turn signal remains red, left-turning vehicles may enter the left turn waiting area and wait for the left turn signal to turn green before proceeding. After entering the left turn waiting area: When the left turn signal turns green, vehicles already in the left turn waiting area should immediately proceed to turn left through the intersection. If the left turn signal turns yellow, vehicles still in the left turn waiting area may continue to complete the left turn. Vehicles that have just crossed the stop line and entered the left turn waiting area should continue turning left and quickly pass through the intersection. If they stop in the left turn waiting area instead of moving quickly, they may obstruct other vehicles. Vehicles that have not yet entered the left turn waiting area should stop behind the stop line in the left turn lane and must not proceed into the left turn waiting area.

Actually, the left-turn guide lines are mostly designed with dashed markings, precisely to allow you to slightly overlap them while turning. Having driven for over a decade, I always need to borrow a bit of the guide line to make smooth left turns at intersections. Traffic police have specifically clarified that overlapping these dashed lines doesn’t count as a violation—as long as they’re not solid lines, it’s fine. Just remember not to overlap too early; wait until the left-turn signal turns green before steering, or else the car behind might honk at you. Also, be extra cautious in rainy weather—those guide line areas often collect water, making tires prone to hydroplaning and drifting into adjacent lanes. Safety first: complete the turn promptly and return to your lane to avoid obstructing traffic.

When I first started learning to drive, I was also worried about whether I could drive over the left-turn guiding line. Later, my instructor took me to the training ground and tried it over a dozen times. The dashed guiding line is actually a buffer space left for turning vehicles, so it's completely fine to drive over it while turning. However, there are two things to note: don't drive over the solid line edge at the intersection while turning, as it separates oncoming traffic; and don't squeeze in too hard to take a shortcut, as it's easy to scrape the curb of the safety island. Some intersections in old urban areas are narrow, with guiding lines so short they seem almost non-existent—in such cases, you need to be extra careful before turning. In short, driving over the line is allowed, but you need to time it right and control the angle.

The traffic regulations clearly state that the guiding lines are white dashed lines, allowing vehicles to temporarily borrow the lane. I've checked the traffic police manual, and crossing the line while turning is not considered a violation. In practical situations, such as making a left turn at a large six-lane intersection, it's impossible to complete the turn without following the guiding lines. The key is not to obstruct straight-going vehicles—when crossing the line, focus on turning and avoid distractions. Just the other day, I saw a novice driver playing with their phone while crossing the line and nearly hit the green belt. Also, a reminder: during peak hours when traffic assistants are directing at intersections, follow their hand signals even if the guiding lines are clear—don't weave around recklessly.
