Objectives:

To assess the effectiveness of a number of laws and other community-based interventions in reducing alcohol-impaired driving and alcohol-related crash fatalities.

Methodology:

Systematic review, conducted according to the methods developed for the Guide to Community Preventive Services. N=76 studies included in the review. ‘Lower blood alcohol concentration (BAC) laws for young and inexperienced drivers’ was selected as a priority policy intervention for review. N=6 studies were included to examine this policy intervention.

Key Findings:

  • All 6 studies analysed data from police incident reports of crashes on public roads. Median post-law follow-up time for the 6 studies was 22 months.

  • All 6 studies reported a post-law reduction in crashes.

  • The studies reported reductions in crashes of between 4 and 24 per cent, depending on the study outcome employed (e.g. fatal crashes, non-fatal injury crashes).

  • There was sufficient evidence that lower BAC laws were effective in reducing crashes among young or inexperienced drivers.

Keywords:

Alcohol-impaired driving, systematic review, effectiveness, crashes.

Comments:

The 6 studies described above were conducted in the U.S.A and Australia.
