“…When analyzing the available sources, the reaction time issue is addressed by quite many of scientists from different parts of the world [15,12,16]. Nevertheless, the availability of scientific publications on the impact of alcohol on driver reaction time is largely limited [24,14]. However, since many drivers who cause a traffic accident are found to have alcohol in their breath and/or blood, we consider it necessary to conduct a scientific study of this type.…”

Each driver should drive according to the actual road traffic rules of the country in which is he currently located. The law systems of various states of Europe allow an increased maximal blood alcohol level of driver. As the fact that no small number of road accidents is caused because of the influence of alcohol on the driver, it is necessary to focus the attention of the society on this issue. The paper deals with the influence of alcohol to change of the reaction time of the driver. During the project of the alcohol effect on the driver and its behaviour, the reaction time of several drivers of a selected group of people was measured. At first (before alcohol drinking) it was assessed the physical and mental condition of the drivers, using a series of question. Subsequently were carried out the measurements by car with sober driver. After this initial measurement the driver began to drink an alcohol and after 20 minutes the level of alcohol in driver´s breath was determined by certificated equipment. After finding of this value was the driver re-tested by the car, where he had to stop the vehicle before simulated barrier. During the tests the stopping distance, the mean fully developed deceleration was explored as the supporting variables. As the most important variable was the driver´s reaction time. It was researched by using of the video-analysing from two synchronized cameras. The aim of this paper is to focus on the fact that there is a dependence between the amount of consumed alcohol and the driver´s reaction time, which significantly affects the road safety. The reaction time of the driver directly influences to the stopping distance thus it is resolute for stopping the vehicle before a barrier

“…Glare of the driver by the opposite vehicle during night-time travel shortens this distance and is one of the most important factors that can cause a traffic accident [11,22]. In the case that the driver is glared by the headlights of a vehicle moving in the opposite direction, the driver's visual acuity is impaired and his vision may be interrupted [14]. The reason for a glare can be, for example, a situation where the driver of the opposite vehicle forbids to switch the long-distance (long-range beam; high beam activation) headlights into dipped-beam headlights mode, headlights inclination is incorrectly aligned, poor technical condition of headlights, or headlights geometry is incorrectly aligned [13,5].…”

Road transport is an essential part of modern life. It brings with itself, besides the desired effects, negative aspects as well. Negative aspect is not only the emissions production but also the traffic accidents occurrence even with tragic consequences. In proportion to traffic intensity, accidents during decreased visibility represent a significant share. A driver has a limited source of information at this time, since only vehicle headlights illuminate the runway and its surroundings. However, these do not only illuminate the roadway ahead of the vehicle, but part of the emitted light also falls into the drivers’ eyes of vehicles in the opposite direction. Thus, the eyes of such glared drivers worse recognize details, or lose the ability to see at all, i.e. vision ability. The level of vision loss depends on the light intensity that falls into the drivers’ eyes in the opposite direction. This light intensity is related not only to the correct headlights alignment (setting) but also to their design. In this paper, three generations of headlights in terms of the light intensity falling into the driver’s eyes of the vehicle in the opposite direction are compared. The headlights alignment of the examined vehicles was checked prior to measurements in accordance with the manufacturer's requirements. Given the fact that intensity of the emitted light is also related to the age of the used source, they have been replaced by the new ones. For the reason of objectivity, examination was performed at night at the New Moon phase, thus it did not light up. The starlight also did not affect the measurement results because it was cloudy, but it did not rain. There were no artificial sources of light near the measuring point..
