 Modern vehicles have both passive and active safety features to assist in accident avoidance and occupant injury limitation. Passive features include ABS (anti-lock braking systems), traction control, stability controls, brake assistance, active lighting, etc to assist avoiding a crash in the first place.

Active systems include air bags, pre-tensioned seat belts, crumple zones, fuel cut-off, etc which operate during and after an impact, many of which are designed specifically to reduce the forces acting upon the occupants and thus reduce the risk and / or level of injuries.

Many whiplash type injuries are thought to occur when the head is subjected to the rapid acceleration caused by the abnormal forces acting upon the vehicle due to a collision, and in particular the rate of acceleration or retardation, often referred to as the Delta V.

It is often the case that a vehicle is involved in a collision, but due to the magnitude of the impact, safety features and / or positioning of the impact that the occupants will not be injured. Therefore, although liability may be admitted, the causation of injuries may not.

We can calculate the Delta V after examination of the vehicles involved which can assist in establishing whether the magnitude of the impact was sufficient to have caused unusual occupant movement. This can aid the Court in deciding whether the occupants were truly injured.

Defendant and Claimant solicitors frequently instuct us to scrutinize third party reports in order to check their accuracy and conclusions, which can often be misleading and flawed in their content. We also check the mathematical modelling of such reports and advise whether they are correct and what assumptions have been made.
