The [hybrid and electric page](https://xpresssmogcenter.com/smog-check/hybrid-and-electric-vehicles/) goes into detail. ## Bring the paperwork, skip the call You do not need to book. Drive in during open hours with your registration or renewal notice, and make sure no tracker or dongle is in the OBD port. The service center answers questions at (775) 828-6996. After a pass, many drivers renew on the spot or online. The DMV allows an emission station that offers renewal to charge up to $10 for the service, and the station keeps separate receipts for the smog check and the renewal. ### Sources - [dmv.nv.gov/emission.htm](https://dmv.nv.gov/emission.htm) (Nevada DMV Emission Control Program: testing area, vehicles tested, exemptions, validity; read 10/19/26) - [dmv.nv.gov/emission_obd.htm](https://dmv.nv.gov/emission_obd.htm) (Nevada DMV OBD page: five-minute test, real-time results, renewing after a pass; read 10/19/26) - [api.census.gov/data/2024/acs/acs5](https://api.census.gov/data/2024/acs/acs5) (U.S. Census Bureau ACS 2020-2024 5-year, ZCTA5 89502, the ZIP shared by Hidden Valley and southeast Reno: population, households, vehicles, commute; retrieved 10/15/26) - [project-osrm.org](https://project-osrm.org) (OpenStreetMap routing, OSRM, light-traffic drive minutes to both Reno locations; retrieved 10/15/26) ### Closer location: Reno South - Call [(775) 828-6996](tel:+17758286996) Mon-Fri 8 am-5 pm, Sat 8 am-3 pm, Sun closed - Address [4993 Longley Ln, Reno, NV 89502](https://www.google.com/maps/dir/?api=1&destination=4993+Longley+Ln%2C+Reno%2C+NV+89502&destination_place_id=ChIJc5xNCcI_mYARXjHn3y79iJw) [Located inside Xpress Oil & Lube Center](https://xpressoilandlube.com/) [Directions](https://www.google.com/maps/dir/?api=1&destination=4993+Longley+Ln%2C+Reno%2C+NV+89502&destination_place_id=ChIJc5xNCcI_mYARXjHn3y79iJw) ### The drive About 8 minutes (2.9 miles) to the Reno South smog check location by car in light traffic (about 16 minutes to Reno Northwest), OpenStreetMap routing (OSRM), retrieved 10/15/26.
