What is an alcolock?

An alcolock is a small device in your vehicle that is connected to the starter motor of your vehicle. Before you can start, you have to blow into the alcolock. The device then measures the amount of alcohol in your breath. If the amount of alcohol in your breath is greater than or equal to 0.2 promille alcohol in your blood, the engine will not start. The alcolock registers how many times you have breathed, the alcohol level, the date and the hour you blew.

Who has to drive with an alcolock?

A judge can impose various penalties for drink-driving. This can range from a fine, to a lapse of the right to drive, to the imposition of an alcolock. This means that you may only drive vehicles that are fitted with an alcolock. The judge can impose this restriction for a period of 1 to 5 years or even for life. In addition you have to follow a mandatory reconversion programme.

What can Vias institute do for you?

The goal of an alcolock is to change behaviour concerning alcohol use and driving. We offer a professional guidance programme (described in the RD of 26 November 2010 concerning the installation of the alcolock and the reconversion programme). The programme starts with a training course about the conditions you must respect and the use of the alcolock device. In addition, regular interviews are held to discuss the data stored and read on the device. You will be called to account for any deviations and transgressions you may have committed. Six months after the start of the programme, you follow a training in group. Here the experiences with the use of the device and keeping driving and drinking separate are shared, even after the device is removed in the future. If the programme has been completed successfully, there will be a final discussion at the end. Together we take stock of the programme and discuss how you can safely drive your vehicle once the alcolock has been removed.
