[Methods of preliminary evaluation of psychophysical skills of drivers]

Drug and medication use-associated impairment of driving skills is increasingly becoming a serious problem. Detecting such DUI drivers is very difficult due to the diversity of drugs that affect the central nervous system (CNS), or to the possibility of using several drugs simultaneously. In practice there are numerous different simple tests, which do not require special equipment and can be used for preliminary detection of persons, who are suspected of taking drugs causing impairment of driving skills. In order to popularize the knowledge on the subject of testing drivers for drug use, the authors review the most commonly used methods of driving skill impairment evaluation reported in the literature, and present the scope of employing such tests in various countries.
