If a person is sentenced to a punishment for causing a serious traffic hazard, driving while intoxicated or driving while seriously intoxicated, the court also imposes a driving ban for at most five years. The police may impose a driving ban also for other violations.
Those sentenced for driving while intoxicated are banned from driving for at least one month. If the offence is driving while seriously intoxicated or causing a serious traffic hazard, the length of the driving ban is at least three months. If a person convicted of driving while intoxicated during a period of five years commits the same crime again or causes a serious traffic hazard, a driving ban for at least six months is imposed on him or her. If both of these offences are aggravated, the driver is banned from driving for at least one year.
If the person who is banned from driving necessarily needs a valid driving licence because of his or her profession or other weighty reasons, a suspended driving ban may be imposed for a trial period of at least one year. A precondition for a suspended driving ban is that the offence has not been conducive to endangering the safety of others. If the convicted person commits a similar offence during the trial period, the driving ban will be enforced. A suspended driving ban may be imposed only once, which means that if the person commits a corresponding offence again, the driving ban is always enforced.
A person guilty of driving while intoxicated or while seriously intoxicated may, at his or her own request which must be presented before the judgment is passed, be ordered a conditional ban on driving for a minimum of one year. During this time he or she will be allowed to drive a car, bus, van, lorry or a tractor to which a breath alcohol ignition interlock device, an alcolock, has been installed (so called supervised right to drive). The police may grant a supervised right to drive already before the court proceedings.
The alcolock prevents ignition if the driver's breath indicates a blood alcohol level of 0.1 per mil. The ignition lock requires the driver to blow into the device while driving as well.
Those who are granted a supervised right to drive by allowing installation of an alcolock must also enter a rehabilitation programme, which includes visits to a specialised doctor or a member of nursing staff to discuss the use of intoxicants, the effects of them on health and the possibilities for rehabilitation. The expenses of the supervised right to drive, around EUR 2,000, are paid by the offender.
