The L plate you get to take off

A white square with one letter in it. Beside it, a ruled report form with tick boxes down the side and a candidate number. Across the corner, at an angle, a stamp.

The plate is the joke. The form is the evidence.

Why is a learner plate a good subject?

Because it's a symbol with an expiry date, and almost nothing else is.

People display it because they have to, resent it for months, and then take it off. Wearing one after the fact is a small piece of irony that only works on exactly one day and for exactly one person — which is a much sharper occasion than most gifts get.

It's also instantly readable. A single letter in a square is about as strong as a chest graphic gets.

What does the report form add?

Proof, and the texture that stops it being a meme.

An examiner's sheet is a specific-looking document: ruled boxes, small categories, a count of minors, a signature line. Set beside the plate it turns a joke into a record — the same reason a real number lands harder than a slogan.

The number of minor faults is the detail people volunteer unprompted for the rest of their lives.

Should it be a real form?

Drawn fresh, in the shape of one.

Driving authorities' actual test forms carry their own layouts, crests and wording, and those belong to the agency — a reproduction is somebody's official document, which is a bad thing to print at any scale. The form's shape is generic: ruled rows, tick boxes, a stamp.

The plate itself is a road-signage convention rather than anybody's design, which puts it in the same place as any piece of standard signage.

Is this only for the person who passed?

Mostly, and that's a feature rather than a limitation.

It's a shirt with a date attached to it — one person, one afternoon, one result. Some clothes are meant to be worn for years and some are meant to mark a day. A first driving licence is squarely the second kind, and choosing it for that is not a compromise.

The same logic runs through everything in this section: the occasion is the design brief.

What about somebody who failed the first time?

Print the second attempt, with the number on it.

ATTEMPT 3 is funnier, warmer and more true than a clean pass, and most people who took three attempts are entirely happy to say so once it's behind them. The version to avoid is one that jokes about it before they've passed.

Timing is the whole judgement here, and the person giving it knows.

Does it work for other tests?

Anything with a threshold and a document.

A first solo flight, a licence renewal at seventy, a motorcycle test, a boat certificate, a qualification with a registration number. Each has a plate, a badge, a card or a form that stops applying — or starts applying — on one particular day.

The motorcycle version has its own visual world entirely, built around the machine's own paperwork.

Does it print well?

Very — this is a two-element design with enormous contrast.

A solid square with a single letterform is unmissable from across a room, and the form beside it is ruled line work that reads as texture at distance and detail up close. The stamp is the only fine element and it should be bolder than a real one.

Deep red is the conventional colour and it works; black, cream and racing green all suit it too. Two inks — the plate colour and one dark — is enough.

How do I get one made?

Describe it at JustOG — the date, the fault count, and what the stamp should say. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.

Designs other people have published are in the shop.

They spent a year with that letter on the car. One day of wearing it deliberately seems fair.
