The purpose of this study was to investigate the effects of the secondary tasks such as sending text message (STM) and searching navigation (SN) on skin conductance level (SCL) during driving. The participants included 29 taxi drivers; 14 males aged 56.7 ± 4.3 with 29.7 ± 7.0 years of driving experiences and 15 females aged 55.5 ± 3.5 with 20.1 ± 5.7 years of driving experiences. All subjects were instructed to keep a certain distance (30m) from the car ahead and a constant speed (80km/h or 100km/h). SCL was measured during driving only and driving with secondary tasks. SCL was more increased during the driving with secondary tasks than driving only. By increasing the driving speed, SCL was increased during the driving with secondary taks. Secondary tasks increased an activation of sympathetic nerve system. However, there were no significant differences in the SCL according to gender.
