What is the lane with serrated edges on both sides?
3 Answers
The lane with serrated edges on both sides is a tidal lane, primarily designed to alleviate traffic pressure and specifically established for peak traffic flow periods. When driving on a serrated lane, it is essential to follow the direction indicated by the traffic signals. Turn left when instructed to turn left and go straight when instructed to go straight, even if the route differs from the original plan; moreover, whether turning left or going straight, once entering the variable-direction lane, do not cross the lane markings. Other road markings: Yellow solid and dashed lines: When encountering yellow markings, the dashed lines can be crossed, but the solid lines must not be crossed, and it is prohibited to cross the solid line or overtake on the opposite side. No-stopping grid lines: Never park your vehicle within the grid lines, as these markings are typically placed at special intersections or entrances/exits, and parking in these areas constitutes a traffic violation. Channelizing lines: These are usually set up at intersections, ramps, or U-turn areas, and parking is also prohibited within channelizing line zones. When encountering channelizing lines, always drive according to the specified requirements and avoid crossing or driving over the lines.
The lanes with serrated edges on both sides are bus-only lanes, typically open exclusively to buses during peak hours. Private cars or other social vehicles entering these lanes will be captured by cameras and fined. When I first learned to drive, I didn't pay attention to these details and accidentally entered once, resulting in a 200-yuan ticket. Since then, I've been extra cautious. These types of lanes are very common on urban main roads, such as Beijing's ring roads or Shanghai's Yan'an Road. The serrated markings are designed to be particularly eye-catching, precisely to remind drivers not to cross the boundary and reduce the risk of traffic accidents. Additionally, prioritizing buses can alleviate congestion and improve public transportation efficiency. Everyone should pay more attention to road signs while driving, especially during rain or at night when visibility is poor, and plan routes in advance to avoid these areas. Developing the habit of checking traffic signs is key. Both beginners and occasional drivers should learn from this incident—safe driving is the top priority.
The zigzag-shaped lanes on both sides are dedicated bus lanes. Private vehicles should not enter them, or they will be caught by cameras and face fines. With over 20 years of driving experience, I've seen countless cases of traffic congestion caused by reckless lane changes. These serrated markings are usually found at the lane edges in bright colors, making it easy for drivers to identify the boundaries at a glance. Especially during peak hours in the morning and evening, these lanes are exclusively for buses. Private cars entering them not only violate traffic laws but also pose dangers—buses have large bodies and sudden braking can easily lead to rear-end collisions. Some cities even impose time restrictions, such as prohibiting entry from 7 AM to 9 AM. Remember to frequently check your rearview mirror and road signs while driving to develop safe habits. Don't change lanes recklessly for temporary convenience. The benefit of bus lanes is that they make urban traffic more orderly—only when everyone follows the rules can travel become smoother.
