ABSTRACT
Driving is a complex activity which requires the driver to be in perfect psychophysical condition in order for them to be able to cope with the ever changing traffic environment (Gras, Planes and Font-Mayolas, 2008). However, despite the complexity of the traffic environment, many drivers feel capable of carrying out secondary activities at the same time as driving. In Spain, research has shown that the most common of these secondary activities are: talking to a passenger, smoking, using a mobile phone and adjusting the stereo (Gras, Planes, Font-Mayolas, Sullman, Jiménez and Prat, 2012; RACC, 2006). Not surprisingly, there is extensive evidence that engaging in a secondary activity while driving increases the likelihood of having a road traffic accident (Klauer, Dingus, Neale, Sudweeks and Ramsey, 2006; Stutts, Reinfurt, Staplin and Rodgman, 2001). Specifically, in Spain it has been estimated that 37 per cent of motor vehicle crashes are caused by driver distraction (WHO, 2011).
