(1) In cases of negligible regulatory offences, the administrative authority may caution the person concerned, and impose a cautionary fine from five to fifty-five euros. It may administer a caution without imposing a cautionary fine.
(2) The caution in accordance with subsection (1) sentence 1 is only effective if the person concerned, having been informed of his or her right of refusal, agrees to being cautioned and pays the cautionary fine as required by the administrative authority, either immediately or within a period which is to be set at one week, at the agency indicated therefor or at the post office by remittance to such agency. The above time limit is to be set if the person concerned is unable to pay the cautionary fine immediately, or if it amounts to more than ten euros.
(3) A certificate is issued in respect of the caution in accordance with subsection (1) sentence 1 of the amount of the cautionary fine, of payment or, where applicable, of the time limit set for payment. Costs (fees and expenses) are not charged.
(4) If the caution in accordance with subsection (1) sentence 1 has become effective, the offence may no longer be prosecuted in respect of the factual and legal aspects giving rise to the caution.
