While the Code is predominantly about traffic conditions and laws, knowledge of what the road/air signs mean and so on, there are some extensions to it. There are a wide variety of hotels, inns and guests houses dotted along the main traffic routes and it is expected that the proprietors ensure their guests uphold the Code while on their property. This is important given most of these places advertise direct access to Yellow Brick Road A1 Section 1, Section 2 and so on as one of their many advantages.
What the Kingdom does not want are drunken guests going straight on to the highways and causing trouble/accidents. Those proprietors who uphold proper conduct by their travelling guests are rewarded with tax breaks. Those that do not get visited by the fairy squad and the only way to avoid a return lecture at length about behaviour and threats about what exactly it is they can do with their wands must amend their behaviour at once. Hanastrew, squad leader, is renowned for her lecturing qualities. Once heard never forgotten. She’s been known to set off avalanches on a “good” day!
Littering is strictly forbidden on the ground or by the maliciously magical who like nothing better than to artificially place objects in the sky for fliers to crash into and fall off their broomsticks. This is happening less since the late Chief Witch instructed her people to obliterate those who did this, which led to the belief she had been a victim of it, but she refused to confirm or deny this.
Everybody has to be re-tested on their knowledge of the Code every ten years. The latter stages of magical education introduce students to it for the first time (though the general do’s and don’ts of flying are introduced at the very start of their schooling). Teachers are also re-assessed. They take the equivalent of the Advanced Driving Instructor exams based on Earth and are stripped of their licence to teach if they fail. You can always tell when a teacher is about to be re-assessed. Anxiety levels (and therefore general grumpiness) go through the roof. On the plus side, teachers tend to have every sympathy for students revising for exams. There is a kind of “we’re all in the same boat” mentality here.
