This study reports on an effort to evaluate and interrelate the existence and strength of two core laws and fourteen expanded laws designed to (a) control the sales of alcohol, (b) prevent possession and consumption of alcohol, and (c) prevent alcohol impaired driving by youth aged 20 and younger. Our first analysis determined if the enactment of the possession and purchase laws (the two core minimum legal drinking age laws) was associated with a reduction in the ratio of drinking to nondrinking drivers aged 20 and younger who were involved in fatal crashes controlling for as many variables as possible. The ANOVA results suggest that in the presence of numerous covariates, the possession and purchase laws account for an 11.2% (p = 0.041) reduction in the ratio measure. Our second analysis determined whether the existence and strength of any of the 16 underage drinking laws was associated with a reduction in the percentage of drivers aged 20 and younger involved in fatal crashes who were drinking. In the regression analyses, making it illegal to use a false identification to purchase alcohol was significant. From state to state, a unit difference (increase) in the strength of the False ID Use law was associated with a 7.3% smaller outcome measure (p = .034).

The minimum legal drinking age 21 (MLDA 21) legislation in the United States (U.S.) has been documented as one of the most effective public health measures adopted in recent times. This study reports on an effort to evaluate and interrelate a basic set of 16 laws directed at younger than age 21 youth that are designed to (a) control the sales of alcohol to youth, (b) prevent possession and consumption of alcohol by youth, and (c) prevent alcohol impaired driving by those younger than age 21. The first objective of this study was to determine whether there was any relationship between the existence and strength of the various underage drinking laws in a State and the percentage of younger than age 21 drivers involved in fatal crashes who were drinking. After controlling for various factors, the only significant finding that emerged was for the existence and strength of the law making it illegal for an underage person to use fake identification ( p <0.016). The second objective was...

In this study, we aimed to determine whether three minimum legal drinking age 21 (MLDA-21) laws-dram shop liability, responsible beverage service (RBS) training, and state control of alcohol sales-have had an impact on underage drinking and driving fatal crashes using annual state-level data, and compared states with strong laws to those with weak laws to examine their effect on beer consumption and fatal crash ratios. Using the Fatality Analysis Reporting System, we calculated the ratio of drinking to nondrinking drivers under age 21 involved in fatal crashes as our key outcome measure. We used structural equation modeling to evaluate the three MLDA-21 laws. We controlled for covariates known to impact fatal crashes including: 17 additional MLDA-21 laws; administrative license revocation; blood alcohol concentration limits of.08 and.10 for driving; seat belt laws; sobriety checkpoint frequency; unemployment rates; and vehicle miles traveled. Outcome variables, in addition to the fa...

Background-Effective policies that can reduce alcohol use behaviors and impaired driving among young people at a population-level are needed. Graduated driver licensing (GDL) laws increase the driving privileges of young novice drivers as they age and gain more driving experience. In this study we seek to determine the effects of GDLs on risky driving behaviors of youth and to assess if GDLs have an unintended effect on underage drinking behaviors. Methods-We utilized 2000-2013 data on 12 th grade students from the Monitoring the Future (MTF) study, an ongoing, annual national survey (since 1975) that studies the substance use behaviors of adolescents, as well as data on GDL laws obtained via the Insurance Institute for Highway Safety (IIHS). We conducted a series of regular logistic regression models that included fixed effects for year and state, and adjusted for demographic characteristics, school characteristics, and other state alcohol policies. Results-Total weighted sample size was 129,289 12 th graders. Past month alcohol use and binge drinking (i.e., ≥5 drinks on one occasion) in the past two weeks were 45% and 26%, respectively. Seventeen percent of respondents reported riding with a driver who drank alcohol. Nearly 12% reported driving in the past two weeks after drinking alcohol, and 7% reported driving after binge drinking. Over half of students lived in a state with a "good" GDL law. The logistic regression models suggest a link between restrictive GDL policies and a reduction of alcohol use behaviors and risky driving behaviors among youth.

The research literature on the relationship of alcohol consumption to motor vehicle crash risk clearly implicates the importance of minimizing the use of alcohol in conjunction with the operation of motor vehicles. However, there has been relatively little documentation of the direct impact of changes in beveragespecific alcohol sales on the most common surrogate for alcohol-involved traffic crashes, single-vehicle nightime fatalities. Similarly, there have been few studies of the relationship between the physical availability of alcohol and fatal crash rates which have concurrently controlled for differences in alcohol sales. Indeed, the possibility that reduced availability might lead to increases rather than decreases in fatal crashes (due to increased driving after drinking) has not been adequately tested. This paper presents a series of analyses of time-series cross-sectional data from 38 states over 12 years to evaluate the impact of changes in alcohol sales and the physical availability of alcohol upon single-vehicle nighttime fatal crashes. The results of the study showed, first, that independent of a number of economic and demographic covariates, rates of singlevehicle nighttime fatal crashes were most strongly related to sales of beer and less so to sales of spirits and wine. Second, net of beverage-specific alcohol sales, the physical availability of alcohol was not related to measurable changes in fatal crash rates. Thus, reductions in availability intended to reduce alcohol sales and problems would not appear to increase traffic-related crashes through increased driving exposure.

Background: There is a considerable body of prior research indicating that a number of public policies that limit alcohol availability affect youth traffic fatalities. These limitations can be economic (e.g., beverage taxation), physical (e.g., numbers or operating hours of alcohol outlets), or demographic (e.g., minimum legal drinking age). The estimated impacts of these policies differ widely across studies. A full-price theoretical approach suggests that people weigh the benefits of drinking against the sum of all the associated costs, including the price of the beverages themselves plus the difficulty of obtaining them and any additional risks of injury or punishment related to their use. This study tested one prediction of this model, namely that the impact from changing one availabilityrelated cost depends on the level of other components of full cost.
