Reaction time is a crucial factor in driving safety, determining driver’s ability to respond to unexpected road events. This study evaluates reaction time using the Vienna Testing System (VTS). The primary objective is to understand the reaction times measured during controlled cognitive tests. A total of 20 drivers participated in the study completing both the VTS tests namely Determination Test and Reaction Test. The VTS tests measured reaction time in a controlled setting, focusing on motor response speed and decision-making under time constraints. The VTS Determination Test shows measurement of decision speed and accuracy to a number of stimuli. The Reaction Test measured reaction time in milliseconds in response to a number of visual and auditory cues. Motor time measured in milliseconds, which is the time from the start of stimulus till to physical response, is also measured. The Percentile ranks are estimated to scale the individual performances against a standardized sample. The mean reaction times varied from 17 ms to 100 ms, while the motor time varied from 10 ms to 89 ms. The analysis showed that the age (p > 0.90) and the driving experience (p > 0.60) did not influence mean reaction time significantly. This indicates that there are factors other than driver age and experience, for example, cognitive abilities and attention levels of an individual, might have more influence on the reaction time, of-course, needs to be validated by a larger study.
