From an expert’s perspective, the starting point is straightforward: vehicle damage and human injury are not the same thing.
One of the most common misconceptions in personal injury claims is that the severity of vehicle damage determines whether an injury has occurred. Medical experts do not assess injuries by examining repair invoices or photographs of bumpers. They assess claimants.
A low-speed collision may produce no symptoms whatsoever in one individual. The same collision may produce significant symptoms in another. Age, physical fitness, previous injuries, degenerative changes, posture, awareness of the impending impact and individual susceptibility can all influence the outcome. That does not mean every low-speed impact claim is genuine.
It does mean that assumptions based solely on the appearance of vehicle damage are unlikely to provide a complete answer.
When assessing causation, medical experts focus on several key questions. Was the claimant symptom-free before the accident? Is there evidence of previous neck or back problems? Are the reported symptoms consistent with the mechanism of injury? Do the medical records support the claimant’s account? Has the pattern of recovery followed an expected course? These questions are often more informative than the speed of the collision itself.
Pre-existing conditions frequently complicate the picture. Many claimants involved in road traffic accidents have a history of neck pain, previous accidents or age-related degenerative changes. The existence of those factors does not automatically prevent recovery of damages. Equally, it does not mean that all subsequent symptoms should be attributed to the accident.
The expert’s role is to distinguish between pre-existing symptoms and any additional injury caused by the collision. This is where low-speed impact cases often become contentious. Insurers may argue that the forces involved were insufficient to cause injury and claimants may argue that their symptoms began immediately after the collision and persisted despite treatment. The expert witness sits between these competing positions, applying clinical judgement rather than advocacy.
Importantly, medico-legal experts are not asked to determine liability. Nor are they asked to decide whether a claimant is being truthful. Their responsibility is to provide an independent medical opinion based on examination, records and clinical experience.
In practice, most low-speed impact disputes are not about whether a collision occurred. They are about causation. Can this accident explain these symptoms in this claimant?
That question cannot be answered by vehicle photographs alone. It requires a detailed assessment of the individual, their medical history and the available evidence.
Low-speed impact claims will continue to be disputed because they occupy a grey area between engineering arguments and medical evidence. Yet from a medical perspective, the principle remains unchanged. The severity of vehicle damage may be relevant context, but it is only one piece of a much larger clinical picture.
