The aim of this study was to compare three different psychotechnical test batteries in Turkey (Act and React Test system - ART2020, TRAFIKENT, and Vienna Test System) which are used to evaluate safe driving-related ability traits and to evaluate the construct validity of the tests included in these three test systems that claim to measure the same cognitive structures. Therefore, 176 drivers (19-63 years old), who owned a driving license for at least one year and had driven at least 5000 km, were tested in all three systems. Both professional and amateur drivers as well as drivers whose licenses were detained due to speeding, DWI or other violations were included in order to form a heterogeneous and representative sample for the Turkish driver population. Participants completed the three psychotechnical batteries which tested their cognitive and psychomotor skills in a period of two or three days. The analysis of the findings revealed that the three batteries were more compatible for some cognitive abilities whereas they were less compatible for other abilities. For instance, there were higher Similarities among the systems in skills such as reasoning, visual memory, and attention, while there were lower similarities in terms of reaction speed, visual continuity, coordination, speed distance estimation, and visual field. The results were discussed and evaluated so as to improve traffic safety in Turkey, and further suggestions for enhancement in traffic situations followed. (C) 2015 Elsevier Ltd. All rights reserved.
