“…The role of personality in risk research remains unclear despite a plethora of related research (Iversen & Rundmo, 2002). Although a great deal of research has considered the problem of traffic psychology (Arthur, Barrett & Alexander, 1991;Elander, West & French, 1993;Evans, 1991;Golding, 1983;Hansen, 1988;Hilakivi, Veilahti, Asplund, Sinivuo, Lattinen & Koskenuvo, 1989;Lester, 1991;McGuire, 1976, Peck, 1993Signori & Bowman, 1974), the contribution of psychology to the traffic policies has been repeatedly neglected in some European countries such as Portugal (Santos, Correia, Gomes, Caldeira & Cunha, 1995). According to Manstead (1993), in the analysis of rule infringement, socio-cognitive variables such as attention (Theeuwes, 1993), perception (Manstead, 1993;Owsley, Ball, Sloane, Roenker & Bruni, 1991) and judgment processes (Cavallo & Laurent, 1988) should be considered.…”
