For a vehicle to pass an emissions test, what is typically required?

For a vehicle to pass an emissions test, it is essential that it should meet specified exhaust emission standards. Emissions testing is designed to assess the pollutants released from a vehicle's exhaust system to ensure that they fall within environmentally safe limits. This helps to reduce air pollution and protect public health. Vehicles are required to adhere to these standards based on regulations set forth by environmental agencies, which may vary by state.

The other options do not relate directly to the criteria for passing emissions tests. New models may still not meet standards if they have defects, insurance status does not relate to emissions compliance, and a vehicle's color has no bearing on its exhaust emissions at all. Therefore, the focus remains on the vehicle's ability to control emissions as defined by the regulatory standards.
