With a growing population and strings of Spare the Air Days popping up every winter, it's more important than ever to keep particulate matter out of the atmosphere. Potrero Test Only Smog, at the busy intersection of 17th Street and Potrero Avenue, keeps vehicle emissions low, which in turn helps keep Orion's belt visible through the city’s scintillating night-time skies. Sure, smog checks rank down there with buying stamps as the dullest possible errand, but it's the more than just the law – it’s the right thing to do. And thankfully, Potrero makes the process easy, getting customers in and out quickly, while offering up suggestions on how to run a cleaner automobile in between those biannual smog tests.
