The keeper of the vehicle has the option of a so-called exemption if he can prove that he did not use the vehicle at the time of the offense. The cases are as follows.

Under the Kkt., the operator is exempt from paying the administrative fine if the vehicle was unlawfully removed from their possession prior to the date of the violation (e.g., as a result of theft) and (by filing a report or obtaining a suspensive decision) proves that, in connection with the unlawfulness, it initiated the appropriate administrative proceedings prior to the delivery of the decision imposing the fine.

The operator shall also be exempt from paying the administrative fine if, prior to the violation, the vehicle was made available for use by another natural person or legal entity, and the person using the vehicle proves this with a statement in a private document* with full probative force, or, in the case of vehicles that may participate in road traffic with a waybill or consignment note under separate legislation, with a waybill or consignment note containing:

• the magisterial marking of the vehicle,
• the name, place of birth, time and address of the natural person operator and customer used,
• in the case of a keeper and user of the vehicle of a non-natural person, the name and address of its registered office (premises),
• and an indication of the period for which the user has taken over the use of the vehicle from the keeper of the vehicle.

Pursuant to the relevant government decree, the authority shall impose an administrative fine within 70 days of the violation in respect of Article 21 (1) a)-g) and j) of the Kkt. and within 150 days of the violation with regard to Article 21 (1) h) of the Kkt. The 70-day deadline does not apply to proceedings for the imposition of administrative fines on users, appeal proceedings, judicial review, or new proceedings ordered in these proceedings.

The first-instance proceedings initiated due to a breach of the rules specified in points a) to g) and j) of paragraph (1) of Article 21 of the Kkt. shall be terminated within four months of the breach of the rules, and the first-instance proceedings initiated due to a breach of the rules specified in point h) of paragraph (1) of Article 21 shall be terminated within five months of the breach of the rules.
