Minnesota ranges between 7.3 and 9.7 motor vehicle deaths per 100K population and has no safety, emissions, or VIN inspections. It does have a climate directly comparable to that of NH.
NH ranges between 7.9 and 11.1 per 100K population and has onerous safety inspections. NH loses.
Comparing by deaths per 100M vehicle miles, Minnesota ranges from 0.6 to 0.7 and NH ranges from 0.7 to 1.0. NH loses again.
Comparing by deaths per 10K vehicles, Minnesota ranges from 0.6 to 0.8 and NH ranges from 0.7 to 1.1. NH loses 3 out of 3.
Key takeaway is that even if they did make us safer, vehicle problems only account for 2% of accidents anyway. It's almost entirely driver error that causes accidents.
Another point they mention is that there is no evidence that they are effective in the 30 years some states have required them.

Fenton is no longer in the House. He’s now a state Senator.
