In general, the responsibility lies with the driver who collides with the car that cuts in line. Here are some driving precautions: 1. Pay attention to speed: Unless on a highway, it's generally advisable to maintain a stable speed around 60 km/h, which is more conducive to vehicle control. 2. Frequently check the rearview mirrors: Rearview mirrors allow you to observe the road conditions on both sides and behind the vehicle, especially when changing lanes, reversing, or overtaking, where they play a crucial role. 3. Maintain a safe distance: If the car in front brakes or cuts in, most drivers' immediate reaction is to hit the brakes. Sometimes, excessive tension can lead to oversteering, causing traffic accidents. Therefore, keeping a safe distance from the car ahead is crucial. When a car cuts in, it's important to slow down appropriately and yield.

From my daily driving experience, the responsibility in such situations usually lies with the car that cuts in, as it violates traffic rules by forcing its way into your lane, infringing on your right of way. When you're driving normally, if the other car squeezes in without signaling, any resulting collision would typically be judged by traffic police as primarily or even entirely the fault of the car that cut in. This is based on traffic safety laws: any lane change must not affect vehicles going straight. As the following car, while you have a duty to yield, it doesn't mean you must compromise safety. So in real-life situations, if someone cuts in, I recommend slowing down in time to avoid them—don't let emotions lead to a collision. Although cutting in is annoying, handling it calmly can prevent disputes from escalating and potential risks. Plus, having dashcam evidence will make the claims process smoother.

I always advocate defensive driving when behind the wheel to minimize accident risks. In terms of liability, if a rear-end collision involves a vehicle that clearly violated traffic rules by cutting in, the responsibility likely falls on the merging party. However, real-world scenarios aren't absolute: if the following car was speeding or distracted and failed to avoid the collision, they might share partial blame. Therefore, my approach is to always maintain sufficient following distance and stay alert to the movements of vehicles ahead. When someone cuts in, avoid abrupt braking or acceleration; instead, smoothly decelerate to yield. This not only safeguards your safety but also cultivates good driving habits. In the long run, developing the ability to anticipate other drivers' actions is crucial—it helps you proactively handle sudden situations and avoid getting entangled in messy insurance claims.

As an ordinary driver, I have encountered a case of being cut off and colliding. Once on the highway, I was abruptly cut off by another vehicle, and I couldn't react in time, resulting in a collision. The traffic police ruled the other party fully at fault, stating they violated the lane-changing rules. As long as the following vehicle maintains a normal speed and has no operational errors, they are generally not at fault. The key is to gather evidence such as dashcam footage and report to the police as soon as possible, avoiding arguments with the other party. Always be prepared for such sudden incidents while driving.
