All participants possessed a valid driver’s license. Participants reported having a license for a median of 6 years and driving a median of 724 km (450 miles) in a typical month.

3. Methods - Procedures The study was a 2 (signal detection task: on versus off)×2 (distraction: phone versus none) completely within subjects design. Each of the four testing conditions lasted approximately 15 min. Participants completed a practice scenario that lasted approximately 18 min prior to beginning the experimental scenarios.
