Abstract Introduction The aims of this study are: (a) to estimate the prevalence of passengers riding with alcohol-impaired drivers; (b) to investigate the role of demographic factors (age, gender, race/ethnicity, educational status) and relevant driving conditions (time of the day, trip origin, vehicle ownership) on shaping the likelihood of alcohol-impaired driving; (c) to identify and estimate the prevalence of passengers as alternative drivers (PADs); and (d) to examine the role that vehicle ownership plays in shaping the occurrence of PADs. Method Data came from a unique convenience sample of passengers obtained from the 2007 National Roadside Survey, a random sample of drivers from the 48 contiguous states. Results The prevalence of PADs in the targeted population (mostly weekend night vehicles) was higher with drivers at .00<BAC<.08 (17%-43%) than at BAC≥.08 (6%-29%) drivers. The evidence suggests that targeted policies to encourage PADs to drive might be possible. However, vehicle ownership is a large impediment for PADs to act as designated drivers. We speculate that vehicle ownership may be a main reason for the less-than expected success of the “designated driver” concept.
Highlights ► Based on the data from the 2007 National Roadside Survey. ► Drivers and their front row passengers tend to share similar characteristics. ► Some passengers were less impaired than their drivers. ► Vehicle ownership was an impediment for sober passengers to replace drinking drivers.
