In recent years, increase of the accident an old driver causes is a problem. Therefore it's necessary to ascertain driving continuation aptitude of an elderly driver. It is reported that self-assessment of driving skill is important for elderly drivers. However, there are no indexes which estimate it objectively. In this report we made the index which aimed at motor coordination to express self-assessment of driving skill and inspected relationship of motor coordination, self-assessment of driving skill and driving behavior of elderly drivers. In this paper, we have developed systems to evaluate the motor coordination required to continue driving. We decided to deal with timing and a grading as the item to do a movement adjustment necessary to driving, and Repeat reaction task, Prediction of motion task, Chase task were made. Next we did the experiment for 40 people over the age of 65 for the purpose of the thing confirmed about independence of cognitive function tests and relation with uneven reaction. The results showed cognitive function and motor coordination are the function which became independent and uneven reaction may affect the grading exercise coordination.
