Which of the following statements is true regarding emissions standards in Maryland?

The statement that all vehicles must meet specific emissions standards regardless of type is true because Maryland has established regulations that require both gasoline and diesel vehicles to comply with emissions standards to ensure air quality and public health. These standards are set to limit the amount of harmful pollutants that vehicles can emit, addressing issues such as smog and respiratory problems associated with vehicle emissions.

Maryland's emissions program includes regular inspections designed to identify excessive pollution from a wide array of vehicles, not just limited to one type. This comprehensive approach underscores the importance of reducing emissions from all vehicles on the road, including passenger cars, trucks, and SUVs, thereby contributing to cleaner air.

Vehicles that do not meet these standards can face penalties and may be required to undergo repairs or modifications to comply with state regulations. The emphasis on uniform compliance helps to maintain environmental integrity and promotes responsible vehicle ownership across all vehicle categories.
