Evaluation of the usability of symbols indicating the state of automobile lighting

Abstract

The research presented in this paper refers to the ability of drivers to understand the information presented by symbols, which indicate states of automobile lighting. The testing included 4 symbols, two of which were ISO-verified symbols. This study of the usability of symbols on a sample of respondents showed that the understanding of the information presented using symbols is relatively low and ranges between 35.45 % and 70.97 %. Tests of statistical hypotheses revealed even lower values at the population level. Suggestions have been given that should initiate the improvement of the usability of this type of symbol.
