... These combined results suggest that even with a state-regulated number of hours of supervised practice driving during the learner's permit period, at least half of all teens may not be getting the full number of hours of learner's permit driving, much less meeting any other requirement, such as a set number of hours of driving at night. Given this result, adding requirements for parents/teens to use electronic-logging cell phone apps to help track the amount of practice teens are getting may help improve compliance and increase the number of hours of practice that teens actually get during the learner's permit driving phase.

... For example, while more experience with driving at night is likely important, it would be more beneficial to gain experience on higherspeed roadways, in heavy traffic conditions, or in navigating complex road configurations such as roundabouts, multilane intersections, and/or other unique road configurations. A better understanding of teen driving behavior differences in diverse driving conditions could be informative for driver's education instructors and help licensing agencies improve driver testing procedures.

... This research utilized powerful NDS datasets coupled with innovative statistical models that allowed the research team to expand upon previous knowledge and gain critical new results regarding the positive relationship between the number of hours of supervised practice driving during the learner's permit phase and a reduction in SCEs. These analyses also further corroborate research suggesting that more diverse practice driving during the learner's permit phase leads to reductions in KRD rates.
