This study assumes that the speed of switching of attention affects car-driving skills. The Stroop test was performed the bus crew. It measured the time to react to the display of a character. Stroop test steps were to read characters displayed on a PC screen (Condition 1), to state the color of characters (Condition 2), and to switch between stating the color of the characters and reading the character according to the level of sound(220Hz/880Hz) presented with the characters (Condition 3). No significant differences were found between the accident-prone group, non-accident group, and inexperienced group in Conditions 1 and 2. However, the reaction times of the accident-prone group were longer in Condition 3, and the difference between conditions 1, 2 and 3 was larger. Slowness of switching attention in the accident-prone group may have influenced the delay of notice for the transportation others, and eventually leading to the accident.
