Changing lanes by crossing a solid white line at a traffic light intersection is considered a traffic violation and will result in a penalty of 3 demerit points. Below is an introduction to the differences between solid white lines and solid yellow lines: Solid yellow line: It is a prohibition line designed to warn vehicles on the road not to cross the boundary, serving as a warning. When a solid yellow line appears in the middle of the road, its purpose is to separate lanes of different directions, acting like a divider that splits the road into two directions. Function of solid lines: When a solid yellow line is painted at the edge of the road, its role changes to prohibiting parking, indicating that no vehicles are allowed to park in that section, including both long-term and temporary parking. When a solid white line appears in the middle of the road, its purpose is to separate different lanes in the same direction, such as dividing motor vehicle lanes from non-motor vehicle lanes or sidewalks. Cases where crossing a solid white line is allowed: When a traffic accident or other reason causes traffic to stall and waiting would further disrupt traffic flow, crossing the solid white line to change lanes is permitted. Additionally, when directed by traffic police on-site to facilitate their work, crossing is allowed.

Only with more driving experience do you realize that changing lanes over a solid white line is absolutely a violation and will result in penalty points. Once, I accidentally crossed the line to change lanes, was caught by a camera, and got 2 points deducted plus a 200-yuan fine—it really hurt both my wallet and driving record. Solid lines are designed to prohibit random lane changes, mainly for safety to prevent rear-end or side collisions. This type of marking is common on highways or urban roads. If you don’t notice and change lanes over it, you could be penalized by electronic surveillance or traffic police. The safest approach is to check navigation in advance and only change lanes at dashed lines. After developing good habits, I’ve never made such a mistake again. I recommend everyone learn more about the small details of traffic rules.

As someone who frequently pays attention to traffic regulations, I am well aware that crossing a solid white line will inevitably result in penalty points. Chinese traffic rules clearly stipulate that crossing a solid line is a violation of road markings, punishable by a 2-point deduction and a fine. Solid white lines typically appear at sharp turns or multi-lane intersections to guide traffic and prevent chaos. If you accidentally cross the line and are lucky enough not to be caught, you might get away with it, but if captured by cameras, you'll have to face the ticket. When driving daily, I make it a habit to observe road conditions in advance and change lanes at dashed lines for safety. Remember to stay updated with traffic signs, as road markings can vary by section.

Changing lanes over a solid white line will definitely result in penalty points. Traffic authorities set these lines to prevent traffic conflicts. Violating solid line rules creates safety risks and increases the chance of rear-end collisions, hence the strict regulations. Drivers should only change lanes over dashed lines, and pre-planning routes can help avoid issues. Penalties include point deductions and fines, so developing good habits protects yourself.
