Secondhand tobacco smoke is a toxic air contaminant that can reach unsafe levels in enclosed spaces such as cars and other vehicles. As scientific evidence of the health risks of exposure to secondhand smoke has mounted and smoke-free policies in public places have proliferated, a growing number of countries, state and local governments, and employers have taken steps to protect their citizens and employees from secondhand smoke in vehicles. These measures range from prohibiting smoking in public use vehicles, such as business vehicles and public transit, to private or personal use vehicles – specifically vehicles used when children are passengers.

The recent trend in smoke-free state and local legislation has been to expand the definition of “workplace” to include vehicles used for company business. Governing bodies typically pass laws prohibiting smoking in business vehicles to protect the public health. Employers adopt similar policies to protect the health of their employees, and to meet their legal obligation to provide a safe workplace. Concern over health care costs of tobacco-related illnesses has also motivated many employers to adopt policies restricting smoking in company vehicles. Also, employees exposed to secondhand smoke in a workplace may have viable legal claims against their employer.
Examples of smoke-free laws and policies that prohibit smoking in vehicles used for business:
- Iowa Clean Indoor Air Act. Prohibits smoking in public transportation and vehicles owned, leased or provided by employers.
- New York Clean Indoor Air Act. Prohibits smoking in public means of mass transportation and company vehicles.
Exposure to secondhand smoke is particularly dangerous for children, whose organs are small and developing. Children exposed regularly to secondhand smoke are susceptible to increased and severe common childhood illnesses and are at higher risk for serious, long-term diseases. As a result, a growing number of jurisdictions in the United States and abroad have adopted measures regulating smoking in personal vehicles when children are passengers.
Despite the trend to prohibit smoking in enclosed spaces, including cars, where children remain vulnerable, such smoke-free measures often face opposition from those who express concern about privacy and enforcement issues. Proponents of these laws point out the compelling scientific evidence for protecting children from secondhand smoke. They explain that there is no constitutional right to smoke, and that a smoke-free vehicle law does not violate any fundamental privacy right. They also emphasize that the purpose of smoke-free car laws, like child safety seat belt laws, is to protect the health and safety of children, and that these laws are typically enforced in similar ways.

“Public transit” or “mass transportation” typically covers public buses, passenger railways, light rail lines, and other common carriers, as well as publicly owned taxicabs, limousines, boats, vans, trucks and other vehicles that carry members of the general public for public purposes. Federal transportation laws prohibit smoking on vehicles such as interstate buses, while state and local laws regulate smoking on mass transit vehicles within their jurisdictions. Mass transit passenger railroads have their own smoking policies.
- The U.S. Department of Transportation prohibits smoking on all buses transporting passengers in interstate service, with the exception of charter carriers. Violators are subject to a penalty of $550. 49 C.F. R. § 374.201.
