A fine of up to 10,000 euros: Some costumes are prohibited at carnival. If you find 20 euros or more on the street, you should stay away from it.
If there is a hindrance, a fine of 10 euros is possible. Neither vision, hearing nor freedom of movement may be restricted by the costume. It's clear: opulent disguises with a monkey head attached are out of the question on the steering wheel. In the event of an accident, fully comprehensive insurance can refuse to cover the event.
