Vehicular air pollution has created an ongoing public health crisis. We examine how different communities’ driving volume and exposure to vehicular air pollution relate to race/ethnicity and socioeconomic status, and how this varies across the region. How much vehicular pollution are different communities exposed to in relation to how much—and where—their residents drive?  We answer this question in the context of race, class, and driving in Los Angeles County and find a negative association between miles driven and exposure to vehicular emissions. That is, all else equal, residents of communities that drive more tend to be less exposed to vehicular pollution themselves.
