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.

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 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.

Evaluation of a High-Visibility Enforcement Seat Belt Program on the Blue Ridge Parkway

The National Park Service implemented a high-visibility seat belt enforcement program on the Blue Ridge Parkway (BRP), involving low-cost media and strong enforcement partnerships, activity associated with significant increases in observed seat belt use on the BRP.
