The mandatory practice of psychological assessment on drivers and candidates for the National Driver's License (CNH) is the best known attribution of the psychologist in the traffic context. It is understood that the action of driving demands minimal cognitive skills that are of great relevance to driver behavior. That said, this work presents the objective of identifying in the literature which minimal psychological constructs have been pointed out as relevant in the psychological evaluation of candidates for the National Driving License. A qualitative and exploratory narrative bibliographic research was carried out, to gather the data, national scientific articles were searched in the Scielo, Pepsic, Scholar Google (Academic Google) databases, through triage by titles and keywords: "traffic", "psychological evaluation", "driver", and "psychological constructs". As a result of the research it was possible to verify that the constructs measured in any driver in the psychological expertise must be: concentrated attention, divided attention, alternating attention, visual memory, intelligence, critical judgment/behavior, and personality traits. It was then concluded that even with the minimum psychological conditions determined in resolution, there is still insufficiency in the systematization of these psychological characteristics of the candidates for the National Driver's License that can serve as a parameter for the work of the psychologist.
