The introduction of safety measures in vehicles does not only change the vehicle characteristics but also changes driver behavior. Drivers’ perception towards the use of advanced safety systems in vehicles could affect speeding intention and behaviors which could increase the risk of road traffic crashes. The present study investigates the extent to which driver’s speed selection behaviors are related to perceived control and intention towards the use of advanced vehicle safety systems. A sample of 354 fully licensed Ghanaian drivers, including 278 males and 76 females participated in the study at 2 Times points separated by 3-months. The primary data was subjected to principal axis factoring analysis with Promax rotation which revealed seven interpretable factors from 31 items of the questionnaire. The factors were further subjected to confirmatory factor analysis for validating constructs. Structural equation modeling was applied to address the aims of the study. The study result revealed a significant positive correlation between attitude toward speeding, subjective norm and perceived behavioral control (PBC) constructs and found that these constructs have a positive relationship with the intention to speed. The drivers’ intention to speed and PBC positively influence violation and error. However, positive behavior had no significant relation with intention to speed and PBC. Intention partially mediated the relationship between PBC and violation and fully mediated PBC and error.
