What is the On-Road Emissions Program?
The On-Road Emissions Program consists of equipment that directs an infrared and ultra violet beam across one lane of traffic to measure exhaust pollutants of vehicles as they drive by. Pollutants that are measured are hydrocarbons, carbon monoxide, and nitric oxide. You can click here to learn more about each pollutant. As the vehicle passes the equipment, a camera takes a picture of the vehicle’s license plate while the measurements are taken of the vehicle’s exhaust. This process allows a large number of vehicles to be observed with little or no inconvenience to the vehicle operator.
