Do you know what rocker panels are? No? Well, one listener found out hers were rusted during her annual car inspection — and that they were in need of a pricey repair. Vermont is one of just nine states that still requires annual safety inspections for all cars. And over and over, car inspections — especially car inspections that end in failure — bring frustrated Vermonters to the BLS question box.  Three listeners want to know why Vermont’s inspection requirements persist, even as other states have axed theirs. And they ask: Do inspections actually make the roads here safer? For photos from our trip to Brian’s North End Automotive (feat. Potato the dog) check out the web version of this story.
