Accident Reconstruction is the effort to determine, from whatever information is available, how the traffic accident occurred. Describing the events of the accident, in appropriate detail, is the aim of accident reconstruction.

Driving strategy and evasive tactics may be inferred in reconstruction from descriptions of position and movement. This is done by relating velocity and position of one vehicle or pedestrian to another, or relating velocity and position to features of the surroundings, such as view obstructions, grades, curves and traffic control devices. 

Traffic Law violations are mainly a matter of driving strategy, for example, position on the road, speed and signaling to turn or stop. Laws specify what drivers and pedestrians must do or not do in using roads. Therefore, when one has determined by accident reconstruction how the road was used, determining whether the use violated some law.

Reconstruction suggests circumstances or conditions that were contributing factors, that is, had they been different, the accident would not have occurred.

When two or more eyewitness informants differ greatly in reports of their observations, reconstruction can be very helpful in deciding which of their reports to believe or in some cases, whether to believe any of their reports. NAL BACKGROUND

Johan Joubert is known to me for a number of years. 

I have always found his work of a very high and professional standard. 

It is refreshing that irrespective of whether he is compiling a report on the request of the prosecution, or on request of the defence, he always demonstrates an objective approach in finding answers to the issue at hand. 

He is truly a witness of the court and not a ‘hired gun’ for a interested party.

He jealously protects his integrity and reputation and I can without any hesitation recommend him to be utilised as an expert in his field.
