US License Plate Quiz

In late 1974 a New Hampshire carpenter named George Maynard took a razor blade to his license plate and cut two words out of it — and that small act of vandalism is the reason a license plate quiz is a stranger thing than it looks. Every plate you just tried to identify was designed by a government. The colours, the silhouette, the three or four words along the bottom: none of it was chosen by a stylist chasing beauty. Somebody in a statehouse decided what their state should say to strangers, and then made about a million copies of it a year and bolted them to private cars.

A Carpenter in New Hampshire Took a Razor Blade to His Plate

George and Maxine Maynard were Jehovah's Witnesses. They objected to "Live Free or Die" on religious grounds — the motto asked them to endorse the idea that dying was preferable to a loss of political liberty, which is not a thing their faith allows them to say. So George clipped the words off the plate. New Hampshire law made it a misdemeanour to obscure any part of a plate, and he was cited three times inside six weeks. He refused to pay the fines and served fifteen days in the county jail.

In 1977 the Supreme Court took his side, 6–3. Chief Justice Burger wrote that the First Amendment protects "the right to refrain from speaking at all," and that New Hampshire had effectively conscripted its drivers into using their private property as a "mobile billboard" for the State's ideological message. That phrase is the most useful three words anyone has written about license plates. It is also the reason the serial on the New Hampshire plate in this quiz reads 430 705 — that is where the case sits in the US Reports.

So Whose Words Are Those, Exactly?

Here is where it gets genuinely odd. Nearly forty years after Wooley, the Court decided the opposite-facing question. In Walker v. Texas Division, Sons of Confederate Veterans(2015), a group wanted a specialty plate carrying the Confederate battle flag; Texas said no; the group sued on free-speech grounds. The Court held 5–4 that license plate designs are government speech, so Texas was entitled to refuse.

Both rulings stand, and together they describe exactly what a plate is. The state is the author — it picks the slogan, the palette and the picture, and nobody has a right to make it print something else. But you, the driver, cannot be forced to relay the ideological part. You may cover the motto. You may not cover the serial, the state name, the stickers or the expiry date, and a tinted frame that clips any of them will still get you a ticket in most states.

Which is why these things are guessable at all. A slogan on a plate is not marketing copy. It is an official self-description, argued over in a legislature, compressed to about three words, and then issued in the millions.

Idaho Turned a Metal Rectangle Into a Billboard in 1928

Idaho got there first. In 1928 it stamped "Idaho Potatoes" along the bottom of its plates, the first time any state used a vehicle registration to advertise a product. The wording tightened to "Famous Potatoes" in 1957 and has been there ever since, outlasting every other slogan Idaho has floated. Ninety-eight years is a long run for an advertising campaign.

What followed sorted itself into three rough categories, and you can see all three in the quiz above. Some states sell a product. Some sell a destination. And a few skip the economy entirely and sell an idea about themselves.

Illinois is the cheekiest of these. Lincoln was born in Kentucky and died in Washington; Illinois claims him on the strength of the twenty-four years he lived in Springfield, and then registered the phrase as a trademark in 1955 so nobody else could try. If you want the full picture of who is claiming whom, our US Presidents quiz runs through all forty-six.

Every Plate on the Continent Is the Same Size Because of a 1956 Agreement

Before 1957, plates came in whatever size a state felt like stamping. Automakers hated it — a bumper recess had to accommodate anything from a squat rectangle to something nearly a foot and a half across. In 1956 the American Association of Motor Vehicle Administrators and the auto industry agreed on a single standard: six inches by twelve, adopted across the United States, Canada and Mexico, effective with the 1957 issues.

That rectangle is the whole design brief, and it explains almost everything you just looked at. Subtract the serial, which has to stay legible from about a hundred feet, and the space left over for artwork is roughly the size of a business card. So plate art is always a silhouette and never a photograph — a saguaro, a rock face, a bird on a pine bough, four heads on a cliff. It is why slogans are almost never longer than four words. And it is why South Dakota can fit "Great Faces. Great Places." only by setting it in type small enough that half the people reading this quiz squinted at it.

Two States Have Been Arguing on Metal Since 1982

North Carolina put "First in Flight" on its plates in 1982. It refers to Kitty Hawk, where the Flyer left the ground in December 1903, and as a statement of fact it is unimpeachable. Ohio responded with "Birthplace of Aviation," which refers to Dayton, where Wilbur and Orville lived, ran their bicycle shop, and actually designed and built the aircraft. That is also unimpeachable. Two states, one pair of brothers, several million rectangles of stamped aluminium, and no sign of a truce.

Ohio then managed to make it worse. When the state unveiled a redesigned plate in November 2021, the Wright Flyer was drawn towing a celebratory banner — attached to the front of the aircraft. The plane was flying backwards. The BMV caught it after the public reveal and corrected the artwork before mass production, but the original image had already gone around the world. If you mixed those two plates up in the quiz, you are in respectable company: the two states have spent forty years making sure they both say the same thing.

Here's What Your Three Cue Scores Are Actually Measuring

The twenty plates are not one task. They are three, and your result splits them apart because they draw on completely different kinds of memory. A slogan asks you to retrieve a fact you were told. A silhouette asks you to recognise a thing you have seen. A bare colour scheme asks you to identify a design system with no label on it at all.

That last group is the interesting one: California, Delaware, Colorado, New York, Maryland and Vermont. Strip the state name off those six and there is no word and no picture left to help you — only a red script wordmark, a black field with gold digits, a green ridgeline, a gold field with a blue band, a heraldic quartering, and a plate that is simply green. Naming one of them is the same cognitive job as identifying a brand from its packaging with the logo peeled off. It is also the cleanest possible test of whether you have genuinely looked at the country or only read about it. The US map quiz runs the same experiment on state outlines rather than state designs, and most people score noticeably differently on the two.

Four States Ban Billboards. Three of Them Are in This Quiz.

Vermont, Maine, Alaska and Hawaii are the only US states that prohibit outdoor advertising billboards outright. Hawaii did it first, in 1927. Alaska wrote it in at statehood and voters reaffirmed it in 1998. Vermont passed its ban in 1968 and had the existing boards down within seven years. Maine followed in 1977.

Three of those four appear in the quiz above, and this is where Burger's "mobile billboard" stops being a metaphor. On a road in Vermont or Maine, the plate on the car in front of you is very close to the only state-sanctioned advertising you will pass all day. The two states answered that in opposite ways. Vermont issued the plainest plate in the whole set — a green field, white letters, four words along the bottom, and nothing else. Hawaii went the other direction entirely and put a rainbow on every registered vehicle in the state. Same legal vacuum, two completely different instincts about what to do with it.

Reading Your Result: Six Bands and Three Cue Scores

Your result carries two independent readings, and they are allowed to disagree. The band is how many of the twenty you got. The cue split is which kind of plate you got them from, and that is often the more revealing half.

🏁 Plate Reader (19–20). Not guesswork. A score this high means you cleared at least one of the six plates that carry no slogan and no artwork, which is the section almost everyone drops points in. You are carrying a mental catalogue of state design systems, not just a list of state facts.

🛣️ Interstate Regular (16–18). The score of somebody who has spent real hours in traffic outside their home state. The slogans went down easily and most of the silhouettes followed; what slipped was almost certainly Delaware, Maryland or Vermont — plates that give you a palette and nothing else.

🚙 Rest Stop Scholar (12–15). Comfortably above the middle. You know the famous plates cold — the potato, the rainbow, Rushmore — and you can reason your way to several more from a slogan. The designs that identify a state purely through colour and typography are still getting past you.

🧭 Glovebox Guesser (8–11). You caught the loud ones and worked out a couple from the words. Anything that asked you to recognise a colour scheme instead of reading a phrase went the other way. This is the most common shape of result for people who mostly drive in one region.

🌫️ Rear-View Blur (4–7). License plates are the classic example of something almost everyone looks at daily and nobody actually reads. A handful of hits, nearly all on plates whose slogan spelled out the answer, is the honest version of that.

🚧 Wrong Lane (0–3). The state name was blacked out on every single plate, which removes the one element anyone normally reads. The answer sheet at the end of the quiz is a five-minute tour of all twenty designs — it is worth more than the score was.

Alongside the band you get one of four reading styles. Word Reader means the slogan track was your strongest: you are pulling stored facts and matching them to phrases. Shape Reader means the graphics carried you, which is recognition rather than recall — faster and longer-lasting, but it only fires for things you have actually seen. Design Reader means colour and layout was your best track, which is rare and the most impressive of the three. Even Read means no single cue carried you, which is rarer still; most people lean hard on either the words or the pictures.

The Slogans Are Being Quietly Flattened Out

Something is happening to plate design that has nothing to do with taste. Plates are read by machines now — tolling gantries, parking enforcement, police cameras — and automated readers do badly with busy backgrounds, low-contrast serials and decorative gradients washing across the characters. The design pressure runs one way: flatter fields, higher contrast, less scenery. The kind of plate that makes a quiz like this one possible is exactly the kind of plate optical character recognition would rather not see.

At the same time the medium itself is changing. Digital plates — a powered display where the stamped aluminium used to be — are already street-legal in California, Arizona, Michigan and Texas. On one of those, the message is software. It can be updated remotely, overnight, without the car ever going near a DMV. Which drags George Maynard's question back into the present in a form nobody in 1977 had to think about: if the slogan on your car can be rewritten from a server while you sleep, whose speech is it that week? If you want the same recall problem with the artwork stripped away entirely, the 50 states quiz gives you a blank list and no pictures at all — and the full design history of every state plate is worth an afternoon on its own.
