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

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.

Speaking of changing lanes over solid lines in tunnels, I've been driving for over a decade and have the most say in this matter. I remember a few years ago when I was driving on the highway through a tunnel, the navigation alerted me that the exit was coming up. In a hurry, I crossed the solid line to change lanes, and by the end of the month, I received a text message notifying me that I had been deducted 3 points. Looking back now, I feel particularly regretful. The drastic changes in lighting inside the tunnel at that time almost caused me to collide with a small truck in the adjacent lane. Deducting points is a small matter, but safety is paramount. Getting 3 points deducted for such a solid line lane change is truly not unfair. I recommend everyone choose their lane two to three hundred meters before entering the tunnel; changing lanes in advance is the safest. There are cameras in tunnels, and nowadays, electronic police capture violations with high accuracy—don’t think about finding loopholes. Moreover, lanes in tunnels are narrow, and changing lanes over solid lines can easily lead to scratches. The repair costs could end up being much more expensive than the fine.

New drivers like us are most afraid of changing lanes in tunnels. I just got my license last month, and the instructor repeatedly emphasized that you must never cross the solid line in a tunnel. I saw the question bank on my driving test app, which clearly states that changing lanes over a solid line in a tunnel violates the prohibition marking instructions, resulting in a 3-point deduction and a fine ranging from 20 to 200 yuan. Last week, during a road trip with friends, I stopped him from crossing the solid line to overtake in a tunnel. Remember, the white solid line in a tunnel is like a wall—changing lanes over it is particularly prone to accidents: first, the poor lighting in tunnels makes it hard for cars behind to see lane changes; second, some tunnels have curves that create blind spots; third, sudden lane changes can cause cars behind to brake abruptly. The 3-point deduction is justified—it's better to miss an exit than take the risk. Safety always comes first.

According to the latest traffic regulations, crossing solid lines to change lanes in tunnels constitutes a violation of prohibition signs, and drivers will be penalized with 3 demerit points by law. This standard is uniformly applied nationwide, whether in urban tunnels or highway tunnels. Solid lines serve as dividing lines that prohibit crossing, which is especially crucial in special sections like tunnels. The primary reason is that the enclosed space of tunnels severely limits safe distances for lane changes, and even slight carelessness can trigger chain-rear-end collisions. The purpose of demerit points is not punitive but serves as a warning. In actual enforcement, the success rate of automatic camera captures is very high, and some regions also employ sonar monitoring. Therefore, even if the vehicle ahead is moving slowly, it's safest to wait until exiting the tunnel's dashed line area before overtaking.

The experience of being fined for crossing the solid line in the Yangtze River Tunnel last year is still fresh in my memory. I was in a hurry to pick up a client, and seeing the truck in front moving too slowly, I crossed the white line to change lanes. Three days later, I received a violation notice: 3 points deducted and a 200 yuan fine. The traffic police explained that the penalty for crossing solid lines in tunnels is uniformly set nationwide, starting at 3 points. Later, I looked it up and learned that such violations are extremely hazardous: tunnels usually have a speed limit of 80 km/h, with large blind spots when changing lanes; insufficient lighting reduces the reaction time of following vehicles; and the high risk of fire makes rescue efforts difficult. Now, I always choose my lane at least 500 meters before entering a tunnel. If I make a wrong choice, I'd rather take a detour than cross the solid line. Points and fines are minor losses compared to the regret of causing an accident or injury.

As a frequent long-distance driver, I must remind everyone about the rules for driving in tunnels. Crossing solid lines to change lanes will definitely result in a 3-point deduction, as clearly stated in Article 90 of the Road Traffic Safety Law. The reasons for not touching solid lines in tunnels are practical: the narrow space makes lane-changing angles insufficient, easily leading to scraping the wall; the alternating light and dark conditions reduce the effectiveness of rearview mirrors; and some long tunnels have slopes that increase the difficulty of vehicle control. I have personally witnessed a five-car pileup caused by a lane change in a tunnel, where the leading vehicle was fully responsible, resulting in a 6-point deduction and hefty compensation. It is advisable to set your navigation to plan your lane at least 1 kilometer in advance. If you encounter a slow-moving vehicle, don’t rush—wait until you are at least 200 meters out of the tunnel before changing lanes safely. Losing those 3 points is not unjust—don’t gamble with your life.
