Abstract

This state level case based study is aimed at providing a complete picture of contributing factors for fatal crashes caused by younger drivers (younger than age 25) in Florida. Results showed that nonhuman factors were primary contributing causes in only 6% of the crashes, but secondary and tertiary contributing factors in up to 25% of those crashes. The most common nonhuman factor was tire blowout/tread separation. Common human factors included alcohol use, inattention, and high speed. Younger drivers were at fault in 62% of crashes in which they were involved, and they were highly overrepresented in fault in forward impacts with control loss due to high speeds and abrupt steering input. At the time of the fatal crash, younger drivers were more likely to have had passengers in the vehicle than older drivers and approximately one in four younger at fault drivers was under the influence of alcohol. However, most of the youngest (16 to 17 year olds) at fault drivers were in compliance with nighttime and passenger restriction statutes of graduated driver licensing at the time of the fatal crash. The findings imply that there still remains gaps and weaknesses in current driving programs aimed at younger drivers.
