The aim of the present study is to identify which of subjective workload dimensions are influenced by driving experience and situation complexity, and which ones influence driving performance. Method: Fifty-seven young drivers [15 traditionally trained novices, 12 early-trained novices, 15 with three years of experience and 15 with at least five years of experience] were randomly assigned to three situations [simple, moderately complex and very complex] in a driving simulator. Self-reported levels of workload during unexpected pedestrian crossings were collected by a questionnaire [NASA-TLX] between each situation. Results and discussion: Three workload subscales decreased with experience and increased with situation complexity, and one subscale was correlated to driving performance.
