Abstract
Laws relating to alcohol considerations in road traffic casework are discussed along with various scientific principles. Pre-analytical considerations are highlighted as important issues. Guidelines concerning fundamental knowledge, such as alcohol elimination rates, blood to breath ratios and use of the so-called Widmark formula are presented. Calculations useful to such cases are discussed and suggestions for their implementation made. A format for the presentation of the data in a logical sequence in forensic reports, along with other important background information for such cases, is suggested along with some possible scientific defences and observations.
