How many points are deducted for changing lanes over a solid line in a tunnel?

[SavannahLee]

Changing lanes over a solid line in a tunnel results in a deduction of 3 points. Below is an introduction to the relevant content about crossing lines: Solid lines: Whether it's a single yellow line or a double yellow line, as long as it's a solid line, crossing is strictly prohibited, such as overtaking, turning, or making a U-turn. Under normal driving conditions, you should not cross the line. Dashed lines: Whether it's a single yellow line or a double yellow line, as long as it's a dashed line, you can overtake or make a U-turn when it's safe to do so. Single yellow lines are generally used on roads with four or fewer lanes (including bicycle lanes), while double yellow lines are typically used on wider roads. At an intersection with a red light, you can make a U-turn over a solid line only when the left-turn signal is green. If there is no dedicated U-turn signal light and no prohibition sign for U-turns, it means the intersection allows U-turns. Unlike left-turning vehicles, U-turning vehicles can proceed during a red light, provided they do not interfere with the normal passage of other vehicles.
