Great prices, great staff. Everything was ready quickly. I highly recommend Ontario Smog.

I took my car and my dad’s car and they were very friendly and professional. The price is reasonable, and they get the job done quickly and efficiently. I recommend coming here to do your smog check.
Valarie Trujillo
I recommend the services of Ontario Smog Check, in Ontario, CA. I was in and out in 15 minutes, paid only $35 cash with my yelp coupon, and the customer service was excellent! I plan to bring my truck here for next year’s smog check.
