I thought in the county where I live in TX the cars had to be 25 years old until we could drop the emissions tests and have just a safety inspection. Turns out gasoline cars only need to be 24 years old so I can drive my car about a year from now without being inspected. I've heard some counties or states don't have inspections. What are the reasons for not having inspections in some places? What's your inspection cut-off year?
