Natural Gas Systems: Suggested Changes to Truck and Motorcoach Regulations and Inspection Procedures

This report provides recommendations for suggested changes needed to Federal Motor Carrier
Safety Regulations (FMCSRs), North American Standard inspection procedures, and out-ofservice (OOS) criteria to accommodate and facilitate the use of natural gas (compressed or
liquefied) as an alternative to traditional fuels such as diesel and gasoline in commercial
vehicles. In addition to providing specific recommendations for changes, this report summarizes
the process used to arrive at these recommendations, which included a literature review and gap
analysis, industry site visits/consultations, and a formal peer review process.
