Whether a U-turn on a ramp is captured depends on two scenarios: if there are cameras on the ramp, the action will be recorded and classified as a traffic violation. If there are no cameras on the ramp, it will not be captured. Prohibited U-turn situations are as follows: U-turns are prohibited where there is a 'No U-turn' or 'No Left Turn' sign: If there is a sign prohibiting U-turns, then U-turns are not allowed at that intersection. A U-turn is an extension of a left turn, so if there is a 'No Left Turn' sign at an intersection, U-turns are also prohibited there. U-turns are prohibited at crosswalks: U-turns are not allowed at crosswalks. If U-turns are permitted at an intersection, you must cross the crosswalk before making the U-turn and not perform the U-turn on the crosswalk. U-turns are prohibited when there is no left-turn lane: Even in the leftmost lane, if there is no sign permitting left turns, U-turns are not allowed. U-turns are prohibited within the second left-turn lane: When a vehicle is in the second left-turn lane, it cannot make a U-turn. In the absence of any signs, U-turns are only allowed in the innermost left-turn lane. U-turns are prohibited at solid yellow lines: U-turns are not allowed at solid yellow lines. Even if there is a sign permitting U-turns, you must wait for the green light and cross the stop line to make the U-turn. U-turns are prohibited on highways: Crossing the central divider to make a U-turn on a highway is illegal and will result in a fine and 12 penalty points. If you miss an exit on the highway, continue to the next exit and leave the highway; do not attempt an illegal U-turn. U-turn precautions: When making a U-turn, you should activate the left turn signal in advance, the maximum speed should not exceed 30 km/h, and you must not obstruct other vehicles or pedestrians traveling normally.
