I was a state licensed vehicle safety inspector here in OK until the state (thankfully) abolished this worthless program. It’s sole purpose was to put money into the state troopers retirement fund.
According to the state a proper inspection should take 1 hour and 15 minutes and performed on the rack. Out of the 5 dollar charge the mechanic got 2. Think a mechanic is going to give one iota about an inspection when they’re not only getting 2 bucks but losing money on the jobs they should be working on.
When OK decided to recertify years ago I was sent kicking and screaming to be recertified. I made up my mind I was going to fail the test. I intentionally answered 70% of them incorrectly.
What did it get me? They passed me anyway. After that I pencil whipped them. I’d drive the car into the shop, hit the horn/wipers/lights, take a quick look, and pass them. The state was asking questions as to why their surveys showed 15% of vehicles should fail and yet our shop never had one rejection slip written.
Someone finally realized the program was worthless and ended it. To avoid losing the money into the trooper retirement fund they just added more to the fines for traffic violations.
