In different driving situations, drivers encounters with different types of stimuli, visual or auditory, from different sources, and for safe performance should have an accurate perception of them. Driving context also provide a complex information processing situation from view point of direction, continuous, quantity and ambiguity of stimulus. So, drivers’ safety and performance are influenced significantly by attention skills of drivers. Previous studies revealed that, failure of attention and deficiency of information processing is one of the major causes of accidents (Shinar, 1993). From ergonomics prospective, any incompatibility between cognitive resources and job demands results in deterioration of performance and occurrence of errors.
