Which Automotive Smog Testing Services Does Your Vehicle Need?


It’s a fallacy that all vehicle emission inspection centers offer the same services. While every local smog testing shop does provide CO2 testing and other emissions inspections, the range of services and attention to customer needs varies greatly from shop to shop.

Some vehicle emissions inspection shops are test-only stations, while others offer testing and repairs to faulty emissions systems. Others provide free follow-up testing, great customer service, fast turnaround times, STAR-certified testing, Consumer Assistance Program repairs and more.

Before starting your search for a quality smog testing shop, think about your needs and expectations. Ask yourself the following questions to get started:

  1. Do I need or want to get a smog test from a STAR smog testing station?
  2. Is the DMV requiring me to have my vehicle emissions inspection at a test-only station?
  3. Can I choose to visit a test and repair shop?
  4. Do I understand the difference between test-only stations and test and repair shops so I can find the shop that best fits my needs?
  5. Do I need a smog check because I’m selling my car?
  6. Do I want to choose among smog test shops that offer value and quality instead of cheap smog inspections alone?
  7. What personal and professional qualities am I looking for in a smog testing shop and its employees?
  8. Do I want a Diamond Certified auto emissions inspection service that’s rated Highest in Quality and Helpful Expertise® and backed by the Diamond Certified Performance Guarantee?
