demonstrated that cell phone use contributes to accidents, slower reactions, and more dangerous driving patterns (e.g., Strayer, Drews, & Johnston, 2003). Further studies have shown that cell phone conversation disrupts visual scanning and change detection (McCarley et al., 2004), and causes a form of inattention blindness whereby observers fail to see information that falls directly in their line of gaze (Strayer & Drews, 2007). Although a great deal is known about the detrimental effects of cellular communication on driving, little is known about why people engage in this dangerous behavior. Drivers persist despite overwhelming evidence documenting the hazards associated with such use. Ironically, there is often wide spread support for regulating the use of wireless devices while driving, in many cases by individuals who regularly engage in these activities. People appear to be sensitive to the risks of others ’ cell phone use, but blind to the risks associated with their own use (Sanbonmatsu, Strayer, Medeiros-Ward, & Watson, 2012). We hypothesize that the cognitive distraction caused by the use of a cell phone impairs drivers ’ ability to notice their own impaired driving. That is, cell phone use may induce a form of inattention blindness that not only diminishes drivers ’ ability to detect important information in the driving environment but that also impairs their ability to self-regulate (e.g., Carver & Scheier, 1998) their driving performance. Drivers generally monitor their performanc
