title: Adult-supervised practice driving for adolescent learners: The current state and directions for interventions.
abstract: BACKGROUND
  The aim of this study was to quantify and identify correlates to the amount of parent-supervised behind-the-wheel practice hours by novice teen drivers.
  
  
  METHODS
  A national survey of 945 parents of recently licensed teen drivers was conducted. Multivariate logistic regression was used to identify factors related to the number of practice hours completed.
  
  
  RESULTS
  Sixty-one percent of parents reported practicing 50 or more hours with their teen. Two-parent involvement was associated with more practice hours, though use of a professional driving instructor was not. Parents of teens licensed in states mandating 50 or more hours of practice driving were more likely to report at least 50 practice hours than those in states mandating 20-40 hours or in states without mandates.
  
  
  CONCLUSIONS
  The findings underscore the integral role of parents in the learning to drive process and provide further support for GDL requirements for practice hours.
