Inspections help keep junk and unsafe vehicles off the road. It's a pretty inexpensive safeguard for the highways.
I would imagine, on the contrary, it's an extraordinary expense to the taxpayers for which the fees do not cover the expense of having the inspections. I also suspect that the social costs it avoids, accidents due to equipment failures, are much more common and cause much less property damage than you might expect. I recall seeing some data on NHTSA's website regarding tire failures and the average amount of property damage caused by tire failures. The average loss was less than what a single tire for my pickup costs. Most people simply do not drive enough or keep an older car long enough for major, catastrophic failures to cause any harm to anyone else. When's the last time you saw a vehicle on the side of the road with a separated tie rod or a broken ball joint that wasn't from an accident? How frequently do you read about a brake failure that causes major bodily injury or property damage? My suspicion suggests that hiring even one more police officer to enforce the laws against distracted driving would be wayyyyy more cost effective than inspecting 100% of the vehicles to catch a fraction of 1% of the vehicles out there that are truly dangerous. Not to mention that the ones who aren't complying are probably strongly correlated with the fraction of 1% we're talking about.
Googling "efficacy of vehicle inspections" returned results that overwhelmingly supported abolishing these inspections; one website says that $600 million alone is spent in a single year dealing with them in Pennsylvania. Another website claimed that insurance rates are no lower in states requiring inspections, suggesting that the actuaries share my view--that these inspections are a wash at best. I am not a statistician or professional economist so I don't know the actual answer. But my intuition suggests as I claim above, that vehicle inspections for personal vehicles are more costly than the problem they seek to reduce or eliminate. I would be genuinely surprised to learn otherwise.
