Yeah, that one was easy for me because I live in Pennsylvania but it is understandably difficult for non-Pennsylvanians. I also struggled with West Virginia and Massachusetts (although I feel like I should have gotten the latter; I've seen it plenty of times).
Wow, Pennsylvania has the most meaningless plate of them all! My kids could make that thing in the garage. Hope they got that design cheap from prison labor or something.
Easy. I've lived in TX, WI, NJ, and NM. Recognized the mottos of HI, IL, NH, AK, ID, and VT. Recognized the logo of WY. Got MA on my first try with a lucky guess. Deduced WV from the alliteration (I'd used up most of the other W states). CO was obvious with a little thought. Got NV on about my third try while naming states with mineral industries. That left PA as the only hard one, but since I had over a minute left and can normally win the "fifty states in one minute" quiz, the outcome was never in doubt.
Virginia has the largest amount of license plates and the price for text customization is the lowest. The main license plate is very plain, however, most people don't have this type.
They get a chance to change plates ever couple of years or so, hence must get some right, but flags generally go on for ever. There are mistakes - Texas one is now BORING black and white.
Texas has switched to a plain black on white plate because the peace officers (highway patrol, Texas Rangers, local LEOs, etc.) complained that the old decorative plates made it hard to read the license number—which is the point of a license plate in the first place. My personal favorite license plate isn't from the U.S. at all—it's Baja California's "nacional" (as opposed to "fronterizo"—border-area only) plates.
West Virginia, Colorado, and (I think) New Mexico all have the state name or abbreviation included on the stickers if you zoom in. Any way to change that? Otherwise, great quiz!
Many years ago the Kentucky license plates had the name of the county along the bottom. I live in Missouri but often see cars from nearby states. I kept seeing Indiana plates that had Wander written on the bottom. I commented that Indianapolis must be in Wander County because every Indiana plate I saw had Wander written on them. My husband gave me "the look" and suggested I pay attention the next time the Indiana tourism commercial came on TV. I did, and heard the song, "Wander Indiana, wander Indiana, wander Indiana." (How was I supposed to know they wrote the slogan on their license plates?)
Kansas has got a part of our state seal in the background in light blue containing possibly the best state motto, "Ad Astra Per Aspera," To the Stars Through Difficulty. I love our Latin motto. We've never launched any rockets into space, but one of our tornados once lifted a house and crashed it onto a witch. Man, could that witch sing!
