Cell phone use while driving has been estimated to cause 333,000 crashes each year, resulting in 2,600 deaths and $43 billion in societal costs. An increasing number of states have implemented cell phone laws banning hand-held phone use and texting while driving, but it remains unclear whether these laws reduce calling, texting, or crashes among young drivers. The Objective of this application is to determine across multiple states the impact of cell phone laws and their enforcement on calling and texting while driving, and on rates of injurious and fatal traffic crashes among drivers under age 25. Its Central hypothesis is that, the effectiveness of cell phone laws is impacted by certain provisions of the law, and that most laws have little or no impact unless they include a high degree of enforcement. It will pursue the following specific aims: 1) Determine which provisions of hand-held cell phone bans and which level of enforcement actually reduce roadside-observed calling while driving among drivers under age 25;2) Identify which provisions of texting bans and which level of enforcement reduce self-reported texting or emailing while driving among high school students;and 3) Determine which provisions of hand-held cell phone bans and texting bans, and which level of enforcement reduce traffic crash rates among drivers under age 25. The following legislative provisions will be examined: mode of enforcement (primary enforcement-officers can stop a vehicle for cell phone use only;or secondary enforcement-driver must first be cited for another infraction), total cell phone ban for drivers

Public Health Relevance

Healthy People 2020 has identified motor vehicle crashes as an important public health issue for adolescents (age: 10-19) and young adults (20-24), and cell-phone-related distracted driving is being recognized as an emerging hazard in traffic safety, particularly among young drivers whose cell phone use and crash rate are high. The proposed research will identify the effective and ineffective provisions of cell phone laws in reducing drivr hand-held phone use, texting, and the subsequent crashes, injuries and deaths. It will delineate an optimal law for states to enact new, or enhance existing legislation, and define the level of enforcement needed to achieve actual reductions in driver cell phone use and traffic crashes involving adolescents and young adults;and, will provide much-needed scientific evidence for informing important policy decisions relevant to transportation safety and protection of the traveling public.
