Oceanside Smog is located along South Coast Highway near downtown Oceanside. The site performs smog and emissions checks, a must for those looking to sell their vehicles in the state of California. The site can electronically transfer smog test results to the DMV and offers computerized printouts of results for the customer. Although the site handles only one car at a time, complete tests take about 10 minutes so there is hardly ever a wait. The shop provides couches and a TV for those who are waiting for their test to be completed. Credit cards are accepted and parking is free on site.
