A valley with long commutes
The Census Bureau reports a mean commute of 30.3 minutes for Lemmon Valley workers, the second longest among the places on this site, with 68.6 percent driving alone. A long commute means more miles per year, and a vehicle that works hard is the one most likely to benefit from an early test.
The DMV says a test is good for 90 days and encourages early testing, since it leaves time for repairs before the registration deadline.
Who lives here, by the Census
There are 1,875 households in Lemmon Valley and about 85 percent of them have two or more vehicles. Households here tend to include more than one adult driver and sometimes a work truck. The median age is 53.4.
The Census tables we used do not give a vehicle total for Lemmon Valley, so we do not state one.
Trucks and utility vehicles
Where truck ownership is common, the weight rating decides what the DMV requires. Gasoline vehicles of any weight in the urban Washoe area need a test, and diesels are tested up to 14,000 pounds GVWR. Heavy-duty gasoline vehicles are those at 8,501 pounds or more, and they use the tailpipe method.
For a diesel, a motorhome or a large truck, call the service center before you bring it. The diesel smog check page explains the DMV rules.
Which direction to head
The two drives are within a minute of each other, so choose by what else is on your list. Longley Lane is near the airport and I-580; Mae Anne Avenue is in the northwest. Reno Northwest is open Saturday until 4 pm and Reno South until 3 pm.
Both are inside an Xpress Oil & Lube Center, so an oil change can be done in the same stop. Ask about registration renewal while you are there, and bring the renewal notice so the station can see your vehicle and plate details.
