“…There have been some qualitative interview studies with unlicensed drivers (e.g. Clark & Bobevski, 2008;Ferrante, 2003;Knox et al, 2003;Mirrlees-Black, 1993;Ross & Gonzales, 1988;Silcock, Sunter, van Lottum, & Beuret, 1999), some quantitative mail questionnaire studies (Chang, Woo, & Tseng, 2006;Robinson & Kelso, 1981;Smith & Maisey, 1992;Williams et al, 1984), a quantitative interview study (Wells-Parker & Cosby, 1988) and classroom completed questionnaire study (Knoebel & Ross, 1997). It has been noted that much of the research on unlicensed driving is purely descriptive and fails to illuminate the personal, social and environmental factors underpinning the behaviour and consequently why, employment, family or social factors lead some to drive without a valid licence (Watson, 2003).…”
