Eric, Maryland doesn't even have an inspection system, except when you buy a used car. In MD, the headlights are always adjusted, for profit.
Va. use to have inspections every 6 months. I keep my cars in good shape and I suspect you do too. Inspectors see lots of cars and can tell the good from the bad. Yous must have been a good one.
I have been failed by inspectors before so I learned my lesson.
I took my old Explorer in for inspection and told him I already got new tires, exhaust and brakes done so he wouldn't have to fail me.
