　　The objective of this study was to examine the workload and training effects on five truck driving training tasks (i.e. parallel parking, S-shape lane, T-lane, vertical parking and ramp tasks). The frequency of visual search, blinking rate, driving performance were recorded by a digital driving recording system. A polar electrode belt placed around the chest was utilized to continuously measure the driver’s heart rate. In addition, the NASA-TLX questionnaire was completed after each trial. The duration of the training course was four- weeks. Results of analysis indicated that the performance of driving tasks for parallel parking, T-lane, vertical parking and ramp tasks in the third week of training were better as the same in the final examination. However, the task of S-shape lane was more difficult to learn and required more time to practice. Results of the present study may provide meaningful information applicable to driving training.
