The use of mobile phones in driving is one of the leading causes of driving distraction, which has caused a large number of traffic collisions. The conversion of dual tasks happens when a driver interacts with the navigation system or makes a phone call while driving, and the execution of the latter task could be affected by the former one. This study explores the relationship between smartphone addiction and phone use behavior while driving and the characteristics of drivers with high and low smartphone addiction in driving task conversion. A total of 150 college students were tested using college students' Smartphone Addiction Scale Score (SAS-C) and Questionnaire on Smartphone Usage While Driving, and the top 33% and bottom 33% in SAS-C. A total of 43 students participated in the experiment in which the conversion of tasks was involved. The results showed that: (1) Smartphone addiction has a positive impact related to mobile user behavior when driving, (2) Drivers with high smartphone addiction are more likely to have mobile phone use related to cognitive distraction while driving, (3) Visual distraction has a more significant impact on task conversion of drivers with low smartphone addiction, while cognitive distraction has a more significant impact on task conversion of drivers with high smartphone addiction, and (4) SAS-C total score and psychological characteristics can predict △RT(Response time)under cognitive subtask conditions. The results of this study should help develop programs for driver training and education.
