This driving simulator study investigated drivers' ability to resume manual control from a level 3 automated vehicle. Volunteers were asked to engage in different types of non-driving related tasks including watching videos or texting. During the tasks, a take-over request (TOR) was provided to the drivers in two conditions with and without the TOR display on the task screen. The results showed that, compared to video watching, texting tasks tended to cause delayed driver's responses to the TOR. Further, it was suggested that adding a TOR display on the task screen contributed to reduce collision risk by suppressing continued concentration on the distractive tasks.
