A rear-end collision occurs when one vehicle crashes into the back of another vehicle. This type of accident often happens when the car in front suddenly stops or slows down, and the following driver does not have enough time to react. Common causes include distracted driving, tailgating, and poor weather conditions. In many cases, rear-end collisions result in minor injuries, such as whiplash, but they can also lead to more serious consequences. Insurance companies often assess fault in these accidents, with the driver who rear-ends another vehicle typically being held responsible.
