Who is responsible for a rear-end collision when the front car brakes suddenly?

The rear car is responsible for the collision when the front car brakes suddenly. Here are the relevant details about rear-end collisions: 1. Legal provisions: Article 80 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulates that when a motor vehicle is driving on a highway at a speed exceeding 100 kilometers per hour, it should maintain a distance of more than 100 meters from the vehicle in front in the same lane. When the speed is below 100 kilometers per hour, the distance from the vehicle in front can be appropriately reduced, but the minimum distance should not be less than 50 meters. 2. Liability determination: In a rear-end traffic accident where the rear car collides with the moving front car, the rear car bears full responsibility. If the front car stops on the road without turning on the hazard warning lights and setting up warning signs as required, resulting in a rear-end collision, the front car bears secondary responsibility for the accident, while the rear car bears the primary responsibility.

Oh, I've been driving for over ten years, and in rear-end collisions, the following vehicle is almost always at fault! If the car in front brakes suddenly while driving normally, it's not a violation, and the following car should maintain a safe distance. Once, on a rainy day with slippery roads, a truck in front suddenly braked to avoid an animal, and I was following too closely and hit it directly. The traffic police arrived and immediately ruled me fully responsible, costing me over 8,000 yuan in repairs. Everyone, remember, no matter how urgent the road conditions are, you must leave enough reaction time, especially in blind spots like tunnel entrances. A safe following distance is key to survival—don't tailgate or play with your phone, it endangers both yourself and others.

Last month, I rear-ended another car and had to take full responsibility. The car in front was waiting at a red light when a delivery rider cut in, causing them to brake suddenly. I was only 10 meters behind and couldn't stop in time. The traffic police said no matter why the car in front braked suddenly, failing to maintain a safe distance is always the rear car's fault. Now, I get nervous every time I see brake lights, so I specifically bought a car with automatic emergency braking. Everyone, remember to keep enough distance when driving—at least 50 meters on highways and 20 meters in the city. If you have a dash cam, you might prove the car in front braked intentionally to scam you, but the chances of that are slim.

When learning traffic rules, the instructor repeatedly emphasized: the rear car is at fault in a rear-end collision! Article 43 of the Road Traffic Law states that the rear vehicle must maintain a safe distance from the vehicle in front. Sudden braking by the front car might be to avoid pedestrians or obstacles, which is normal operation. Unless it can be proven that the front car was reversing, rolling back, changing lanes illegally, or intentionally braking suddenly to stage a crash for fraud, then the front car is at fault. I have a friend who was rear-ended because the front car was reversing, and after the traffic police reviewed the surveillance footage, the other party was deemed fully responsible. However, in most cases, the rear car is undeniably at fault, and insurance companies love these kinds of cases the most.

As a novice, I thought the car in front would be fully at fault for slamming on the brakes, but I learned the hard way. That time on the elevated road, the navigation gave the wrong exit, the car ahead braked suddenly and changed lanes, and I couldn't stop in time and hit them. The traffic police pointed at the lane divider markings and said: 'He illegally changed lanes, and you were speeding—primary and secondary responsibility split 70-30.' Turns out rear-end collisions have several liability scenarios, like if the front car straddles lanes, engages in road rage, or has broken brake lights—responsibility could be shared. I recommend installing a dashcam; it can prove your innocence in critical moments.

Having handled hundreds of rear-end collision cases, 90% of them resulted in full liability for the rear vehicle. Sudden braking by the front vehicle during normal driving is not considered a fault, while the rear vehicle failing to maintain a safe distance will bear the responsibility. The compensation process is straightforward: 1. Immediately turn on hazard lights and place a warning triangle. 2. Take photos for evidence without moving the vehicles. 3. Contact traffic police and the insurance company. A special reminder for owners who modified their braking systems: illegal modifications can lead to increased liability. In one case, the rear vehicle had modified calipers but filed a false claim, ultimately not only bearing full liability but also being sued for insurance fraud.
