Motor vehicle crashes are a leading cause of death in the United States. Further, cigarette smoking is associated with negative health and work outcomes. However, scant research on data for the United States has analyzed the association between cigarette smoking rates and motor vehicle death rates. This study fills that void. It estimates the association via ordinary least squares regression on annual state-level data for 2011–2019, controlling for other known factors related to motor vehicle death rates and accounting for year and region fixed effects. Results indicate that the cigarette smoking rates of a state’s population are significantly and directly related to the motor vehicle fatality rates in that state. Further, interaction results indicate that alcohol consumption’s positive association with motor vehicle fatalities is highest in states with more smokers. The findings suggest that smokers may be more likely to die in motor vehicle crashes than non-smokers, and that driver safety programs targeting smokers warrant funding.

在美国，机动车事故是导致死亡的主要原因。此外，吸烟与负面的健康和工作成果有关。然而，对美国数据的研究很少分析吸烟率与机动车死亡率之间的关系。这项研究填补了这一空白。它通过对 2011-2019 年度州级数据的普通最小二乘回归估计该关联，控制与机动车死亡率相关的其他已知因素，并考虑年份和地区的固定效应。结果表明，一个州人口的吸烟率与该州的机动车死亡率显着且直接相关。更远，交互结果表明，在吸烟者较多的州，饮酒与机动车死亡的正相关关系最高。研究结果表明，吸烟者可能比不吸烟者更有可能死于机动车事故，而且针对吸烟者的驾驶员安全计划值得资助。
