Short answer
A rear-end collision occurs when one vehicle strikes the back of another. The trailing driver is often the focus of the investigation, but fault can depend on following distance, speed, brake lights, traffic conditions, sudden movements, and whether another vehicle contributed to the collision.
Rear-end crashes commonly occur in stopped or slowing traffic. Symptoms from neck, back, or other injuries may be immediate or may develop or become more noticeable after the collision. Medical evaluation and consistent documentation can become important to the injury claim. Start with car accidents for broader information.
Why Fault Can Still Be Disputed
An insurer may raise questions about a sudden stop, brake lights, traffic conditions, a prior impact, or another vehicle’s involvement. Photographs, the crash report, witnesses, available video, and vehicle damage can help clarify what occurred. See multi-vehicle crashes when another vehicle contributed to the collision.
Symptoms and Medical Documentation
Rear-end collisions can result in neck, back, shoulder, head, and other injuries. Symptoms can vary from person to person, so the medical records, examination findings, treatment, and recovery are more useful than assumptions based only on the type of crash. See concussion for information about head-injury symptoms.

Frequently asked questions
Personal injury claims are subject to filing deadlines, and the deadline that applies can depend on the facts of the case. Different notice requirements may apply depending on who is involved. Do not use this website to calculate a filing deadline. Speak with an attorney promptly.
Often that driver is the one insurers look at first. Facts can still change the picture — a third vehicle, a disabled car, or a dispute about brake lights. Nobody here can decide fault from a website form.

A concussion is a mild traumatic brain injury that can result from a bump, blow, or jolt to the head or from a hit to the body that causes the head and brain to move rapidly. Symptoms may appear immediately or hours or days later. A CT scan is not used to identify every mild TBI or concussion, although imaging may be used when a clinician is concerned about bleeding or another serious injury.
