Why Frazer-Nash?
Frazer-Nash has over 20 years experience in the analysis and assessment of commercial vehicle rollover, and has provided professional advice on a number of legal disputes.
The challenge
Frazer-Nash was asked to investigate the root cause of a road traffic accident involving vehicle rollover on a roundabout. We provided expert opinion on whether the accident had occurred as a result of human error, or whether the vehicle itself had not been fit for purpose.
The vehicle, a 4x2 tractor pulling a tri-axle flat bed trailer, was attempting to manoeuvre round the roundabout when it rolled over onto its nearside. That day the weather was reported to be windy and dry and no other vehicles were involved.
Our solution
We examined all witness statements, accident photographs, vehicle evidence and related documentation. We then surveyed the radius of the roundabout and contacted the Met Office to establish the potential impact that the wind may have had on causing the accident. This information was incorporated into our supporting calculations.
We also examined the stability of the vehicle and the weight distribution of the trailer, which was loaded with 88 bales of compressed fibre.
