• Abstract:
  Iowa is the only state in the US that gives parents the option to implement or waive a passenger restriction that limits the number of unrelated minor passengers to one for the first six months of licensure. The restriction does not apply to a driver’s sibling, step‐sibling, or a child who resides at the same household as the driver. The Iowa DOT indicated that approximately 90% of parents choose to waive the restriction during 2014, the first year the policy was in effect. This study analyzed crash rates for young drivers who were and were not subject to the passenger restriction in the first six months of intermediate licensure. Rates for the subsequent six months (i.e., after the passenger restriction has ended) were also analyzed. In addition, this study quantified the number of newly‐licensed drivers who were subject to the passenger restriction and their characteristics. Because many young drivers in Iowa obtain the optional minor school license (MSL), which allows teens as young as 14.5 years to drive to and from school and school‐related activities without a supervisor before obtaining his or her intermediate license, MSL and non‐MSL drivers were considered separately.
