GJ Smog Test Only is a facility that tests automobiles for emissions. The garage is located within a large auto complex near downtown. The garage is state certified and offers tests in accordance to California state laws for all vehicles more than six years old. Tests are provided on a first-come, first-served basis and take roughly ten to fifteen minutes. Drivers are welcome to wait on site, though there is no designated waiting area. The garage is large enough to accommodate bigger trucks and full-size vehicles. Though no repair services are provided on site, re-testing is free if done within fifteen days of the initial test.
