Generally, crossing double yellow lines can be captured at a distance of about 20 meters. Illegal U-turns over double yellow lines are recorded either through automatic electronic police surveillance or manual photography by traffic police, with on-the-spot penalties for violators. Here is additional information: 1. Double solid yellow lines: Just like any solid line on the road, double solid yellow lines should not be crossed arbitrarily. Making U-turns, reversing, parking, or speeding on double solid yellow lines is strictly prohibited. Violations typically result in a fine of 200 yuan and a deduction of 3 points. 2. Double dashed yellow lines: Sometimes, double dashed yellow lines appear on roads, which are also part of the double yellow line system. These are usually placed at intersections with lighter traffic, allowing vehicles to cross the double dashed yellow lines to enter the intersection or make U-turns or turns, provided it is safe to do so. 3. Single or double solid yellow lines: Whether it's a single or double solid yellow line, crossing or attempting a U-turn is not allowed. Violators will face severe penalties. 4. No left-turn sign: U-turns are prohibited where there is no left-turn sign. If caught by surveillance cameras, the penalty is an immediate deduction of 12 points. 5. No U-turns on highways: U-turns are strictly forbidden on highways. Even if you miss an exit, you must continue to the next one. Making a U-turn on a highway will result in a 12-point deduction and a corresponding fine.
