Government Fleet Emission Testing Requirements

The Missouri Department of Revenue does not maintain a motor vehicle database of information for government fleet vehicles. So local, state and federal government fleet managers in St. Louis City and St. Louis, St. Charles, Jefferson and Franklin counties must provide the Missouri Department of Natural Resources’ contractor, Opus Inspection, with a yearly list of the vehicles operated by government agencies that need emissions tests.

Missouri Code of State Regulations 10 CSR 10-5.381 explains the test requirements for all vehicles. Government fleet vehicles are subject ti the same testing requirements as privately owned vehicles. Government agencies must keep their fleet vehicles in compliance with this state rule.

As of Jan. 1, 2006, a new state law requires the seller of any vehicle to report this sale to the Missouri Department of Revenue within 30 days of the sale. For more information about selling used vehicles, please visit the Missouri Department of Revenue's website at

Statutes containing the following requirements supersede "as is" declarations on sales contracts or bills of sales to individuals.
