Meta-Analysis of Graduated Driver Licensing Laws

This study assesses the effectiveness of graduated driver licensing programs for reducing total, injury, and fatal crashes among drivers 15 to 20 years old by conducting a meta-analysis of GDL research since 2001. The sample of 14 selected studies represented 13 different States, and three represented GDL programs across most or all U.S. States. Results showed that GDL programs were associated with reductions in traffic crashes of 16 percent for 16-year-olds and 11 percent for 17-year-olds, but no reliable changes in crash outcomes for 18- or 19-year-olds. A reasonable strategy for any State considering passage of a GDL law might involve listing the full range of provisions applicable to that State.

Countermeasures That Work, 8th Edition

This 8th edition of Countermeasures That Work is a basic reference to assist State Highway Safety Offices in selecting effective, evidence-based countermeasures for traffic safety problem areas. These areas include: Alcohol- and Drug-Impaired Driving; Seat Belts and Child Restraints; Speeding and Speed Management; Distracted and Drowsy Driving; Motorcycle Safety; Young Drivers; Older Drivers; Pedestrians; and Bicycles. The guide describes major strategies and countermeasures that are relevant to SHSOs; summarizes strategy/countermeasure use, effectiveness, costs, and implementation time; and provides references to the most important research summaries and individual studies.

Evaluation of State Ignition Interlock Programs:Interlock Use Analyses From 28 States, 2006–2011

In 2010 the Centers for Disease Control and Prevention and NHTSA joined to evaluate ignition interlock programs in selected States to provide information and best practices to States for ignition interlock programs. The project aimed to determine the following: how States can increase interlock use among DWI offenders who are required or eligible to install one; which changes in ignition interlock programs led to increases in ignition interlock use, identification of key features of ignition interlock programs, and which key program features were related to higher ignition interlock use rates.

Comparative Study and Evaluation of SCRAM Use, Recidivism Rates, and Characteristics

Alcohol monitoring devices -- usually ankle bracelet -- monitor and sample alcohol vapors on the skin. They are worn by people convicted of drunk driving and especially those who must maintain sobriety. One such type is called SCRAM (Secure Continuous Remote Alcohol Monitoring), a commercially available device. The impact of SCRAM on the rate of repeat drinking and driving offenders was assessed for some offenders in Nebraska and Wisconsin. There were very few repeat offenses wearing the SCRAM devices, less than 2 percent. When their assignment period was over, offenders using SCRAM showed slightly higher percentages of recidivism than the control offenders, though the difference was not statistically significant.

Effectiveness of Child Passenger Safety Information for the Safe Transportation of Children

Results of the 2013–2014 National Roadside Survey of Alcohol and Drug Use by Drivers

In 2013–2014, the National Highway Traffic Safety Administration conducted the most recent National Roadside Survey of Alcohol and Drug Use by Drivers. This voluntary and anonymous study is the second to collect data on drug use, presenting our first opportunity to examine drug use trends on a national scale. The 2013– 2014 NRS was designed to produce national estimates of alcohol and drug use by weekday daytime and weekend nighttime drivers. 

Evaluation of Washington State Target Zero Teams Project

As part of its "Target Zero" strategic highway safety plan that has the goal to reduce traffic fatalities in Washington to zero by the year 2030, the State of Washington established three detachments of Washington State Patrol (WSP) troopers to focus on nighttime impaired-driving offenses.

Evaluation of the NHTSA Distracted Driving High-Visibility Enforcement Demonstration Projects in California and Delaware

It was concluded that high-visibility enforcement can be implemented over widespread, multi-jurisdictional areas and may reduce the number of people who use handheld cell phones while driving.

Process Overview of the High-Visibility Enforcement Programs Targeting Handheld Device Users in California and Delaware

The information in this process report includes: (1) how to plan and implement a regional/statewide HVE program that targets phone use while driving; (2) distracted driving enforcement practices; and (3) lessons learned from the California and Delaware distracted driving demonstration programs.
