Inattention among drivers of motorised vehicles contributed to almost one in three fatal road crashes between 2011 and 2015. This was shown by an analysis of reports from in-depth crash investigations in Norway. About one-third of inattention-related crashes involved pedestrians who were hit by motorised vehicles, where the driver typically detected the pedestrian too late. Failure to check for information in blind zones or behind other sight obstructions is a typical form of inattention. Distraction by use of mobile phones contribute to between two and four percent of crashes, while other sources of distraction, within or outside of the vehicle, contribute to about ten percent. A review of international research literature showed comparable results. Road user inattention is most likely preventable by a system-oriented approach including a combination of vehicle technology, road and road environment improvements, appropriate signs and markings, education and information, and legal measures and enforcement regarding use of mobile phones and other secondary task involvement during driving.
