Solid line crossing beyond 15-30 meters from the intersection cannot be captured. Reasons: The captured image size is approximately between 15-30 meters, and only vehicles traveling at speeds around 250km/h might avoid being captured. Capture principle: Electronic eyes use induction lines to detect the pressure from vehicles on the road. The signals are collected by sensors and sent to the central processor, then temporarily stored in registers. Penalties for solid line crossing by motor vehicles are as follows: According to relevant regulations: According to Article 90 of the 'Road Traffic Safety Law of the People's Republic of China', motor vehicle drivers who violate road traffic safety laws and regulations regarding road passage shall be given a warning or fined. Driving a motor vehicle in violation of prohibited line markings will result in a 3-point deduction. Penalty: Crossing solid lines to change lanes violates traffic marking instructions and will result in a fine and a 3-point deduction.

I've been driving for many years and often get asked this question. Generally speaking, driving over solid lines is a violation regardless of how far from the intersection. Cameras usually have detection range of 20-30 meters before intersections - for example, line-crossing photo systems rely on ground loops or infrared detection, with coverage distance depending on installation location (some urban sections may have longer ranges). But don't count on luck - cameras have high sensitivity and may capture violations even 50 meters away. The key is to change lanes early; I recommend merging 100-200 meters in advance to avoid disrupting traffic flow or triggering accidents. I remember a friend getting fined for crossing lines, which made me develop the habit of preparing early for safety and peace of mind. Ultimately, obeying rules is fundamental - don't risk it just to save time.

As a tech enthusiast, I've researched traffic monitoring. The distance at which cameras capture lane violations isn't fixed—it depends on the equipment type. For instance, high-definition cameras with AI recognition can detect infractions dozens of meters away. Induction loops embedded in roads typically cover 10 to 30 meters, but newer e-police systems have expanded ranges. In practice, your position is calculated the moment you cross the line—with higher risk closer to intersections. I recommend maintaining at least a 50-meter buffer zone for lane changes, though this doesn't guarantee safety due to camera blind spots. Key point: Modern systems integrate multiple cameras for wide-area coverage, resulting in high violation rates. Developing good habits and planning routes in advance is more crucial.

I usually commute by car, so here's some personal experience. There's no fixed distance for crossing solid lines at intersections that guarantees you'll escape penalties, as camera setups vary—some are fixed and monitor short distances, while others are mobile cameras conducting random checks. The common range is around 20 meters. But don’t gamble on luck: I once tried crossing a line further away and still got a ticket as a lesson. Remember, safety is more important than saving time—changing lanes early reduces accident risks. If you're really unsure, following the rules is always reliable. Simply put, just don’t cross the solid lines.
