Highlights
Since a high proportion of drinkers drive to their drinking destination, promoting the use of alternative transportation (AT) is an important strategy for preventing impaired driving.
The primary goal of this study was to review and synthesize the findings of research studies designed to test the effectiveness of AT programs in reducing alcohol-impaired driving.
After a thorough review, we narrowed down the number of relevant articles to 76 including some background articles and government reports.
There is mixed evidence regarding the effectiveness of AT programs. Some AT programs produced reductions in one or more measures but others were not shown to be effective.
The most successful AT programs typically have social acceptance, a high level of public awareness, are low cost, have year-round availability, provide rides to and from drinking venues, have several sponsors that provide funding), are convenient and are perceived to be safe.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
