Role of habits in cell phone-related driver distractions

Despite increased media attention and legislation banning some forms of cell phone use while driving, drivers continue to engage in illegal cell phone distractions. Several studies have used the theory of planned behavior (TPB) to explain why drivers voluntarily engage in cell phone distractions, and found that TPB constructs (attitudes, social norms, perceived behavioral control) predict intentions to engage in cell phone distractions while driving. Given that cell phone use is ubiquitous, habits that have formed around their general use may lead to automatic engagement in cell phone distractions while driving. This differs from voluntary engagement, in that habits are carried out automatically, with little thought given to the action or its consequences. Thus, in addition to the TPB constructs that explain intentions, habitual factors should also be considered in understanding why drivers use cell phones. A few studies have examined the role of habits in this context, but they only focused on texting behaviors. An online survey was conducted with 227 respondents to investigate the role of habitual cell phone use in driver engagement in a variety of illegal cell phone tasks (e.g., social media, email). Habitual cell phone use was found to explain unique variance in self-reported engagement after controlling for TPB constructs. Overall, the findings indicate that cell-phone-related distractions may not be entirely voluntary; instead, cell phone habits developed outside of the driving context appear to have a significant effect, suggesting that cell phone use while driving may have become automatic to a certain extent.
