Therefore, determining the level of blood alcohol concentration at the moment of the car accident is essential in establishing the legal responsibility of the driver. However this exact determination is in most of the cases difficult, due to the fact that between the moment of the car accident and the collecting of the blood in a medical unity a varying time frame passes, depending essentially of the distance from the place of the car accident and the hospital. Even more, from a juridical point of view, at the moment the blood is taken from the driver in the hospital, this is not representing a social danger anymore because he is not driving. Hence, the retrograde extrapolation of blood alcohol concentration is and should be the legal tool of providing the juridical system a valid answer at the question implying the value of the blood alcohol concentration at the moment the antisocial deed (car accident) had been made. The aim of this article is to theoretically present the scientific method of retrograde extrapolation of blood alcohol concentration and also to highlight its strong and weak points.
