What kind of vehicles can use CNG according to common assumptions?

The assumption that all types of vehicles can use compressed natural gas (CNG) stems from the fuel's versatility and the advancements in technology that allow various vehicle categories to utilize it. CNG is compatible with a wide range of vehicles, including personal cars, buses, light-duty trucks, and heavy-duty vehicles. As manufacturers increasingly produce CNG-ready vehicles and conversions for existing vehicles become more common, the adoption of CNG as a cleaner alternative fuel expands across many vehicle categories. This broad capability is fueled by a growing network of CNG refueling stations and the benefits of using CNG, such as lower emissions and cost-effectiveness, making it an appealing choice for conventional vehicles as well as commercial fleets. Hence, the notion that all types of vehicles can utilize CNG is aligned with current trends and practices in the automotive industry.
