Behaviours of drivers in Serbia: Non-professional versus professional drivers

DBQ has been confirmed in a large number of countries and represents the basis for examining driver behaviour. However, the results of the previously conducted studies indicate differences in the behaviours between different groups of drivers. So, the results must not be generalized, but individual studies should be carried out and the comparative analysis of their results should be performed. The objective of this paper is to carry out a comparative analysis of the behaviours of non-professional and professional drivers on the basis of the undertaken individual studies. Factor analysis showed that the data best fitted into the five-factor solution with the different ranking of various factors according to the type of behaviour and with different percentages of the explanation of variance. The results showed the correlation between non-professional drivers and ordinary and aggressive violations and errors, while professional drivers were associated with positive behaviours. In addition to the correlation with specific behaviour groups, the comparative analysis of these two different driver categories also stated that the same individual characteristics of drivers appeared as predictors of different behaviour types.
