Time4Smog, Berkeley

Every car in the state of California needs a smog check if it is rolled off the assembly line between 1976 and six years ago, if it's more than four years old and is being sold, or if it recently took up residence in a mountain formerly occupied by dwarves. Fortunately, Time4Smog makes it easy to get your vehicle up to code. Simply roll up to one of their seven locations, and you'll be on your way within 15 minutes. It's not all for naught, either: according to the California Air Resources Board, the Smog Check program removes about 400 tons of smog-forming pollutants from the atmosphere every single day.
