[Parallels in blood alcohol and breath alcohol border values and sequelae of "double track" forensic assessment].

This paper deals with the regulation of fixing two limiting values, i.e. an BrAC-dangerous limiting value ("AAK-Gefahrengrenzwert") and an absolute BrAC-value ("absoluter AAK-Grenzwert") according to the BAC-limiting values for the purposes of the forensic appraisement. It is referred to the uneven treatment of alcoholized road-users and to the partly unsolvable difficulties for the calculation with the WIDMARK-values.
