General Conditions of the Alcolock Support Programme

1. By paying the costs of the support programme, you explicitly agree to these general conditions of guidance, even if you do not sign them.


2. Once you have paid the full amount or the first instalment, you will gain access to your online file. You can follow up your file there.


3. You declare that all information you provide and enter is truthful and complete.


4. All guidance is provided in Dutch in the Flemish Region, in French in the Walloon Region, in German in the German-speaking Region, and in French or Dutch in the Brussels-Capital Region. If you do not speak Dutch, French or German, or have insufficient knowledge of these languages, you may be assisted by a family member or friend.


5. During the first year, your data must be downloaded at the service centre every two months. During the second year and all subsequent years, this will take place every six months. If necessary, Vias Institute will organise a meeting with you. If you yourself wish to have an interview with your supervisor, you may always request this from your supervisor.


6. When is an additional personal guidance interview required?

  • You failed to provide a breath sample three times during a retest and an early download was carried out.
  • You were retested three times and recorded three test results of 0.2 ‰ or more. This means that another sober person provided the breath sample in order to start, or that you consumed alcohol after starting your vehicle.
  • You attempted to start your vehicle one or more times while recording a test result of 0.2 ‰ or more.


7. When does the support institution notify the Public Prosecutor’s Office?

  • If you attempt to open or disconnect the device without authorisation from the support institution.
  • If you attempt to damage the device.
  • If you attempt to provide a breath sample using anything other than air from your breath.
  • If you introduce foreign substances into the device in order to eliminate alcohol.
  • If you attempt to start your vehicle without blowing or without using the starter motor.
  • If there are indications that the battery has been disconnected (no power supply for more than 30 minutes).
  • If you repeatedly refuse to provide a breath sample for a retest in the period between two scheduled downloads or during an early download.
  • If you attempt to start your vehicle while seriously or repeatedly under the influence of alcohol.
  • If you drive with a blood alcohol concentration of 0.2 ‰ or more. This may occur if another sober person provided the breath sample at the start or if you consumed alcohol during the car journey.


8. Vias Institute has the right to terminate the guidance programme earlier than planned:

  • If you attempt to disconnect the alcohol interlock without authorisation from the support institution.
  • If payment was not made prior to the start of the first training session.
  • If you opted to pay in instalments and fail to make an intermediate payment.
  • If you fail to attend the support institution three times without prior notice.
  • If you do not attend the scheduled or early downloads at the service centre.
  • If you display negative behaviour during personal interviews or during training sessions at the support institution.


9. Cost of the alcohol interlock programme

For a programme of 12 months, the total cost is €1,200.

If you wish to pay in instalments, this will be organised as follows:

  • First payment: before the introductory interview; amount: €400.
  • Second payment: before the second download at the service centre; amount: €400.
  • Third payment: before the fourth download at the service centre; amount: €400.


If your programme lasts longer than one year, the cost is €250 per additional year or €125 per 6 months. This amount must be paid before the start of the next guidance year.

If an additional download is carried out at the service centre and you are required to attend an interview with your supervisor, an amount of €150 will be charged.


10. Invoicing

We cannot issue invoices for services that have not yet been provided. We do offer the possibility to pay the full amount in one instalment, allowing you to reclaim your traffic fine via the costs of your alcohol interlock programme.

  • A first invoice is issued after the introductory interview.
  • A second invoice is issued after the follow-up moment with your supervisor following the third download at the service centre.
  • A third invoice is issued after the completion of your alcohol interlock programme.
  • If your programme lasts longer than one year or if you follow a lifelong alcohol interlock programme, invoicing will take place once the services for that year have been delivered.


11. Refund policy

  • If you decide not to proceed with the alcohol interlock programme while completing the registration form, no administrative costs will be charged.
  • If you decide not to proceed with the alcohol interlock programme between registration and the introductory interview, an administrative fee of €100 will be charged.
  • If an introductory interview has taken place and you subsequently decide and inform us that you will not proceed with the programme, or if the Public Prosecutor’s Office decides that you may no longer start the programme after you have had the introductory interview with your supervisor, an amount of €400 will be charged.
  • If you or Vias Institute decides to terminate the programme early (see point 8), the stage of the programme at that time will be assessed. Any amount corresponding to services not yet provided will be refunded.


12. The candidate’s data will be treated confidentially. For the purpose of smooth file handling, they are considered to be shared under professional secrecy. Communication between the Public Prosecutor’s Office, the service centre and the support institution concerns only the necessary information.


13. The support programme is conducted in accordance with Article 37/1 and Article 61 § of the Road Traffic Act concerning cases where the validity of the driving licence is restricted to driving motor vehicles equipped with an alcohol interlock.
