“…There is a growing body of evidence to suggest that mobile phone use may comprise a number of distinct behaviours (e.g., Gauld, Lewis, & White, 2013;Nemme & White, 2010;Walsh, White, Hyde, & Watson, 2008) . Recent research has identified differences in driver risk perception for initiating (starting a communication), monitoring/reading (checking for communications and/or reading them), and responding (answering a communication) behaviours, with most drivers perceiving monitoring/reading to be the least risky behaviour of these three (Shi, Xiao, & Atchley, 2016;Waddell & Wiener, 2014). There may be different motivations for young drivers engaging in these three different behaviours; for example, feeling a social pressure to respond may be a contributing factor in young drivers answering communications (Atchley, Atwood, & Boulton, 2011;Lindqvist & Hong, 2011;Nemme & White, 2010).…”
