Although multiple causes of distracted driving are included in such estimates, mobile phone use while driving (MPUWD) is one source of distraction that has attracted the attention of researchers, the media, and public safety officials alike. With public health and safety in mind, the need to investigate factors associated with MPUWD is imperative. Crash statistics inform the public about risk, but are relatively silent about psychological factors that may help better understand who is more likely to engage in this behavior.
