Eagle Rock Test Only is a car shop on the corner of Eagle Rock Blvd. and Norwalk Ave. The shop, as the name indicates, has a singular mission: To provide smog tests. The shop and the staff are state certified to test vehicles to see if they are up to state smog codes. If the vehicle does not pass, the shop offers free retests after the necessary repairs are made. The test does not take very long, and there is a patio table with umbrellas where customers can wait.
