Traffic Accident Reconstruction

TAR Services Functions


TAR Services Experts, Mr Johan Joubert  (Accident Reconstruction, Applied Mathematics Accident Scene, Vehicle Dynamics Expert) and Mr Martin Graham (Mechanical Vehicle Analysis, Vehicle Dynamics and Accident Scene Expert) are both considered as experts in the High Courts in South Africa, Namibia and Botswana).

TAR Services is the only company in South Africa that has both a Reconstruction, Applied Mathematical, Cause Analysis, Physics, Vehicle Dynamics, Interpretation of the Law and  a Mechanical Analysis experts.

Our expertise includes, Pedestrian, Motorcycle, Bicycle, Motor vehicle, Heavy Vehicle and Train Accidents.


Criminal Cases

TAR Services experts are frequently used by the National Prosecution Authority (NPA), Senior Public Prosecutors (SPP), to assist the state prosecution arriving from motor and truck accidents.  Here we are required to investigate and reconstruct traffic accidents where our reports are used for prosecution purposes. 

TAR Services are also frequency used by defence attorneys and defence advocates to defend their clients in criminal matters arising  from vehicle accidents. 

It however has to be stressed that TAR Services are not hired guns and any case depends on the merits of the case and the physical evidence.


Civil Cases

Many criminal cases leads to cases against the Road Accident Fund (RAF).  TAR Services experts are then asked to reconstruct accident to determine the cause of the accident as well as the degree or percentage negligence or contributing negligence from the drivers involved.

TAR Services experts however also defend the Road Accident Fund (RAF) in cases where the driver has no claim according to the merits of the case or even in false claims against the RAF.


Insurance Claims

TAR Services assist many insurance companies including Hollard Insurance, OUTsurance and SANTAM in claims against them where the claimant is suspected of driving his\her vehicle recklessly at the time of suffering the damages to his\her vehicle. 

Although persons take out insurance to cover them for negligence, insurance companies have the right to refuse a claim if it can be proven that the claimant were under the influence of alcohol or drove his vehicle reckless at the time of the accident.

TAR Services are also called as experts in Arbitration where two Insurance companies cannot agree on who's client were responsible for an accident and in order to reduce litigation costs, these cases are referred for arbitration. 


Insurance Fraud

TAR Services are also involved in the investigation of false claims against insurance companies where assessors, tow-in companies, scrap yards  operators and repair shops are involved in. 

Most of these cases involves false claims for vehicle parts or inflated repair quotes.  In these cases having an Expert in Mechanical Analysis as TAR Services has, is vital.


Private claims

TAR Services also assist individuals that has been conned by vehicle repair shops for inflated quotes or where the quality of work done was inferior. In these cases having an Expert in Mechanical Analysis as TAR Services has, is vital.





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 follows naturally, but is often inconclusive.  

Who was driving may also be in accident reconstruction.  Sometimes the question of which vehicle occupant was at the wheel when the accident occurred is in dispute or is not sufficiently answered by reports of informants.  Then an analysis of occupant injuries, positions of bodies and expected vehicle movement to its rest position can lead to useful conclusions.    

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

If there were no eyewitnesses of the collision, reconstruction can sometimes form useful conclusions about how the accident happened from the results of the accident, such as marks on the road and damage to vehicles.



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. 

Always remember that the results of reconstruction are opinions.  Like any conclusions, they are more or less accurate and more or less credible depending on the information on which the reconstruction is based, on who does the reconstruction and on the circumstances under which they were made.  

The reconstruction report will include a listing of the data on which the conclusions were based, explaining any scientific principles involved, describing, at least in a general way, the reasoning leading from the data to the conclusions, and finally evaluating the accuracy and reliability of the conclusions expressed.  This report may include maps, drawings, computer simulations, computer animations, rendered still photographs.   

These items direct attention to the facts available and explain more fully the conclusion.  Reconstruction essentially interprets data gathered in lower levels of investigation.
