Speedway Smog Center is a leading test-only smog provider in Modesto with 18 years of experience. The shop offers fast, reliable, and affordable service six days a week, with technicians bringing over 50 years of experience. As a test-only center, they provide smog inspections without trying to sell additional services or repairs. Customers report the service is very fast, often taking about 10 to 15 minutes, and affordable, with mentions of a good coupon on their website. The staff is described as efficient, kind, friendly, and remembered for hustling to provide great customer experience. While the front desk is noted as efficient and focused on quick service, some clarify this direct manner is just his personality, not rudeness. The business is highly recommended for a good price and quick service, with one customer calling it the best experience ever at a service-based auto business. They are helpful in explaining issues and next steps if a vehicle does not pass inspection.
Very friendly and efficient!! Highly recommend this business. We will be back!

I’ve been using this smog center for several years. The staff have always been friendly and helpful, service prompt, and mostly reasonable prices (engine cover removal is a $45 charge!). Let them know about issues up front and they’ll help save you from headache and wasted money. They also offer coupons on their website.

Speedway is super speedy! Friendly, and efficient. They had my car smogged and on its way in 15 minutes for a very fair price. See their website for a coupon.
