In contrast, there is no corresponding body of regulations applicable to U.S. workers who operate motor vehicles other than large trucks or buses as part of their job duties: i.e., those who operate lighter vehicles that are employer-owned or leased, or those who drive personal vehicles for work purposes. It is true that at-work drivers are covered by the Occupational Safety and Health Administration (OSHA) “general duty clause”, which requires that an employer provide “employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees”.[6]
