The perception of risk when driving is based on the following propositional or cognitive motivational models: Model Risk-Zero and Summala Näätänen (1976) Threat-Avoidance Model of Fuller (1984), homeostatic model Theory of Risk (THR) Wilde (1982) and Hierarchical Model and Van der Molen Bötticher (1985 Montoro, 2004). A transverse or trans non-experimental design was used. In a first phase a provisional instrument relating to cognitive, motivational and attitudinal at risk when driving, which was applied to 41 subjects was drawn aspects incomplete sentences results were obtained by frequency analysis to determine the adjectives that were part of the items for a Likert scale of 200 items, which was tested in 40 subjects. Through a process of discrimination validity of an instrument with reagent 30 items, with a degree of reliability .785 using Cronbach's alpha coefficient was obtained. Finally, a principal components factor analysis with Varimax rotation was performed, yielding four factors that explained a whole 54.4% of the variance.
