✕Common Mistakes
Halt der Transport sauber.
The object of ‘halten’ is accusative, so the article must be ‘den’, not ‘der’.
Halt den Transport saubere.
After ‘halten’ the adjective stays in its base form ‘sauber’, not the inflected ‘saubere’.
Halt Sie den Transport sauber.
If you want the formal ‘Sie’ form, you must use ‘Halten Sie …’, not the du‑imperative ‘Halt’. Mixing forms sounds unnatural.

Cultural Tip
In German‑speaking countries cleanliness on public transport is taken seriously; many cities have fines for littering on buses and trains. Signs often use the short imperative form (e.g., ‘Halt den Transport sauber’) to convey a friendly but firm reminder. Using ‘Bitte’ softens the command and is common in polite requests.
