• Evaluation of changes in teenage driver exposure — an update December 2015

    In 2013, HLDI evaluated changes in teenage driver exposure for calendar years 2006–12. This analysis updates the previous study to include 2013 & 2014. Nationally, teen exposure increased in both years while prime-age exposure continued to decline slightly. Results are consistent with the hypothesis that economic factors play an important role in teen exposure. (Vol. 32, No. 30 | December 2015)

  • Young teen crash risk by vehicle type April 2014

    The purpose of this analysis is to explore the extent to which collision claim frequencies vary by vehicle size and type for 15–17-year-old drivers relative to 35–50-year-old drivers. Thirty-two different vehicle size and type groups were examined and, in all but one, claim frequencies were higher for young teens than for prime-age drivers. (Vol. 31, No. 4 | April 2014)

  • Evaluation of changes in teenage driver exposure September 2013

    The level of insured teenagers has declined between 2006 and 2012. Results suggest that a key factor in the decline has been the recession and the extremely high levels of teen unemployment. Graduated driver licensing laws were shown not to have had a large impact on the recent decline. (Vol. 30, No. 17 | September 2013)

  • Teen crash risk by vehicle type September 2011

    The purpose of this study is to determine if collision claim frequencies for 16- to 19-year-old drivers relative to 35- to 60-year-old drivers vary by vehicle type. Crash rates have been found to vary by vehicle type, size, and weight within a group of similar type. This analysis shows that some of the crash rate differences are amplified for teen drivers compared with prime age drivers. (Vol. 28, No. 7 | September 2011)
