If by "smog" you mean a California Smog Check, allow about 30 minutes for the inspection itself.
But here's the more useful way to think about it:
Total visit = waiting time + inspection time.
If there isn't a line, many straightforward vehicles can be finished relatively quickly. If several customers arrive immediately before you, you'll obviously be there longer.
California uses different inspection procedures depending on the vehicle.
Most 2000-and-newer vehicles are inspected using the vehicle's onboard diagnostic system. Older vehicles generally require tailpipe emissions testing.
RVs, vans and heavy trucks can also require more time simply because of their size and testing requirements.
Most 2000-and-newer vehicles at San Juan Auto Smog don't require an appointment.
If your day is already packed, leave your vehicle with us and pick it up later.
If you live or work close by, let us know. When our workload and staffing permit, we may be able to give you a ride to or from the shop.
If you're coming from Gold River with an older vehicle, RV, van or heavy truck, book ahead so we're ready when you arrive.
