Investigating the motivational factors influencing drivers intentions to unsafe driving behaviours: Speeding and overtaking violations

- ​TPB and DBQ predicted drivers speeding and overtaking intentions.
- Control belief has been the strongest predictor of intentions to violations.
- Drivers were more likely to violate based on their beliefs in the factors.
- Speeding attitude was the most frequent violation compared to overtaking.
- Drivers violate overtaking when perceived factors enhancing the behaviour.

Achieving road safety depends on driver attitudes and behaviours in handling the vehicle on roads. The availability of good road, improvement of vehicle designs and drivers experience lead to reduction in crashes but not prevention of crashes. The study aims to predict the drivers' intentions towards speeding and overtaking violations when under the influence of motivational factors using belief measure of TPB and DBQ variables. To achieve this, questionnaires were randomly administered to a sample of Ghanaian drivers (N = 354) who held valid driving licenses. This study applied regression techniques. The result shows that the components of TPB and DBQ variables were able to predict drivers' intentions towards speeding and overtaking violations. The study further shows that components of TPB made larger contributions to the prediction of divers' intentions to speeding and overtaking than the DBQ. Further analysis revealed that, in the prediction of drivers' intentions, speeding attitude was the most frequent violations compared to overtaking. The drivers tend to involved in overtaking violations when they perceived the driving motivations would enhance the performance of the behaviour. Additionally, control belief has been the strongest predictor of drivers' intentions under the influence of motivations to speeding and overtaking violations. It appeared that the drivers who intended to involve in speeding and overtaking violations had strong beliefs in the factors and are more likely to violate based on their beliefs. The practical implications of the findings for the development of interventions to promote road safety and positive changes are also discussed.
