Emissions Testing in the St. Louis Region
Attention: Update - The Gateway Vehicle Inspection Program’s Vehicle Inspection Database outage has been significantly resolved. Emissions and safety inspections have resumed in the St. Louis area. All inspection stations should restart their inspection equipment to re-establish communication with the database. If connectivity or other technical issues persist, please contact the state’s contractor by email at GVIP@WEP-inc.com; the telephone help desk is currently experiencing technical issues. St. Louis-area motorists are encouraged to contact their preferred inspection station prior to going to the station to verify that testing is available. Assistance with waivers, exemptions or other technical issues is available by contacting the department at 314-416-2115.
To help motorists deal with the current COVID-19 outbreak, the Missouri Department of Natural Resources has extended the time frame for which an emissions test is valid from 60 days to 120 days. Additionally, the Missouri Department of Revenue has extended license plate expiration for an additional 60 days. Motorists whose license plates are supposed to expire in March 2020 have until May 31, 2020 to renew their license plates with no penalties. Please follow this link to see the Department of Revenue’s guidance regarding the extension of motor vehicle registration.
For any questions regarding vehicle emissions inspections please contact us at 314-416-2115 or 800-361-4827, or via email.
