To assess the effectiveness of designated driver programs in reducing alcohol-impaired driving and alcohol-related crashes.
Systematic review, conducted according to the methods developed for the Guide to Community Preventive Services. Nine studies were included which evaluated either population-based campaigns that encouraged designated driver use (n=1), or incentive designated driver programs in drinking venues that provided incentives to patrons to act as designated drivers (n=8).
A 3 month campaign to promote the concept and use of designated drivers reported a 13 per cent increase in telephone survey respondents ‘always’ selecting a designated driver, but no significant change in self-reported alcohol-impaired driving.
Incentive programs based in drinking establishments to encourage people to act as designated drivers showed a median increase of 0.9 in the number of patrons who identified themselves as designated drivers each night after the program was implemented.
In 2 of the studies reviewed, the number of self-identified designated drivers returned to baseline immediately after the enhanced incentives were withdrawn.
All outcome measures had limited value in assessing the potential injury prevention benefits of the programmes.
There is insufficient evidence to determine the effectiveness of either campaign or incentive designated driver programmes for reducing alcohol-impaired driving and crashes.

No studies that assessed the effects of designated driver programs on alcohol-related crashes were found.
