The article gives the results of drivers’ psychophysiological experimental research, accomplished by applying a driving simulator, which measures complex reaction time of traffic participants. In addition, it describes the objectives of test researches, technical- psychophysiological conditions, evaluation of results and interpretation. The driving simulator is a laboratory stand that searches drivers’ reactions during simulated traffic conditions and situations of traffic accidents. During the experiment, we accomplished 385 tests simulating particular traffic acci-dent. In the light of experiment results, we analyzed relationships between alternations of various parameters on pur-pose to determine precisely initial moment of the reactions and the mode of reaction. We also composed dependences of reaction time of traffic participants: influence of alcohol amount on reaction time, influence of alcohol amount on selection of the manoeuvre (for example, tour or brake), changes of more complex parameters (for example, time pe-riod of increasing power which is necessary when pressing a brake-pedal; time period for foot relocation from gas-pedal to brake-pedal; brake-pedal pressing force; amplitude of the wheel turn; etc.). Gained results clearly show how different is drivers reaction to the same damage situation and allows to observe various reaction times, various peak values of amplitudes of the wheel turn and braking acceleration, various processes of the manoeuvre.
