What might result from a vehicle having excessive exhaust emissions?

Having excessive exhaust emissions typically indicates that a vehicle is not operating efficiently or that it may have mechanical issues affecting its emission control systems. This can include problems like a malfunctioning catalytic converter or issues with fuel injection. As a result, when a vehicle is tested for emissions, if the levels exceed the established limits set by environmental regulations, it will fail the emissions inspection.

This failure not only means that the vehicle cannot be registered until the issue is resolved, but it also points to potential environmental concerns as such emissions can contribute to air pollution and health problems in the surrounding community. Therefore, the direct consequence of excessive emissions is a failure in the emissions inspection, highlighting the importance of maintaining vehicles to adhere to environmental standards.
