Questions about Vehicle Emissions Testing
Why do I have to test my
hybrid-electric vehicle?
While it is true that a hybrid-electric vehicle
emits less emissions overall than a similar
sized gasoline-only powered vehicle when operating
as designed, the potential for high emissions
is still present. Hybrid-electric vehicles
are equipped with all the standard emissions
control devices as any other vehicle. If
any of these emission control devices should
deteriorate or fail during the life of the
vehicle, the emissions could potentially exceed
allowable limits during gasoline operating
periods. The vehicle emissions test is
designed to identify these potential emission
control device problems before any significant
emissions increases occur.
