Emissions Testing

Missouri, like many other states, has set up a program to deal with smog and emissions testing in their area. The name of their program is the Gateway Vehicle Inspection Program. The groups that are in charge of running this program are the Missouri State Highway Patrol and the Missouri Department of Natural Resources as well. They work in conjunction to make sure that the process runs smoothly. In terms of those who are required to get their vehicles inspected, residents of St. Louis County, St. Louis City, Franklin County, Jefferson County or St. Charles County are all in this category.
