Many governments have banned strikes in public transportation. Whether this can be justified depends on whether strikes endanger public safety or health. We use time-series and cross-sectional variation in powerful registry data to quantify the effects of public transit strikes on urban populations in Germany. Due to higher traffic volumes and longer travel times, total car hours operated increase by 11 to 13 percent during strikes. This effect is accompanied by a 14 percent increase in vehicle crashes, a 20 percent increase in accident-related injuries, a 14 percent increase in particle pollution, and an 11 percent increase in hospital admissions for respiratory diseases among young children.
