A. Cars are tested for the pollutants called hydrocarbons and carbon monoxide. Hydrocarbons are unburned gasoline particles that contribute to the formation of ground-level ozone often referred to as smog. Carbon monoxide is a colorless, odorless and toxic gas formed from partially burned fuel that can adversely affect mental function, visual acuity and alertness.
