Obligations / cooperation

The persons charged with investigating the offences made punishable by the Road Traffic Act may, in this context, ask you as a driver to stop your motor vehicle and ask for a number of pieces of evidence. You are obliged to comply with this request. In any case, you must properly hand over the following evidence for inspection:

  • registration certificates for the vehicle and any trailer;
  • driver's license;
  • if required: certificate of professional competence for drivers;
  • if applicable, decision granting exemption;
  • if required: disabled persons' card.

(Article 160 paragraph 1 WVW)

Obligations / cooperation

In the context of monitoring compliance with the Road Traffic Act and the detection of offences under the Road Traffic Act, the investigating officer may order you, the driver of a vehicle, to cooperate in an alcohol test. You are obliged to cooperate. If it concerns a breath analysis, this may only be ordered if there is a suspicion. If you have not drunk any alcohol, but have displayed such abnormal driving behaviour that you are suspected of driving under the influence, you are still required to cooperate with a breath analysis.

If there are no grounds for suspicion, the driver of each vehicle, the person who intends to drive a motor vehicle and the escort are obliged to cooperate with a preliminary breath test. These are the breathalyzer tests, for example, during large-scale controls. In contrast to breath analysis based on suspicion, this does not usually take place at the police station. If you have not drunk any alcohol and have not displayed any abnormal driving behaviour, you may still be required to breathe. (Article 160 paragraph 5 sub b WVW).

If you are suspected of driving (driving any vehicle) under the influence of more alcohol than permitted, you may be stopped with your vehicle. If the investigating officer orders you, the driver of a vehicle, to cooperate in an alcohol check on the grounds of suspicion, you are obliged to do so. Suspicion can arise, for example, from the results of the preliminary breath test. How does a suspected alcohol check work?

The persons charged with investigating the offences made punishable by the Road Traffic Act are

1. In the first instance, the investigating officer may only order you to cooperate in a breath analysis. You are then obliged to blow into the device.

2. If, for medical reasons, a breathalyser cannot be required, or if the suspect's cooperation does not result in a completed breathalyser test, or if there is a suspicion that the suspect is under the influence of certain drugs or a combination of drugs and alcohol, the investigating officer may request permission to take a blood test.

3. If consent is not given then an authorised person, often the Public Prosecutor or Assistant Public Prosecutor, can order the suspect to co-operate with the blood test. In that case you are obliged to comply with this order.

4. If you are unable to make your will known, the quantity of blood referred to in the sixth paragraph may be taken by a doctor or nurse with the permission of the public prosecutor, an auxiliary public prosecutor or one of the police officers appointed for that purpose by order of Our Minister of Security and Justice, unless it is plausible that this is undesirable for special medical reasons. The suspect must always have been given the opportunity to give permission first. If necessary you can be ordered to cooperate and then you are obliged to do so. If you refuse to cooperate, the blood sample will be destroyed.

If it transpires or there is a serious suspicion that you have drunk so much that you have committed a criminal offence, an official report will be drawn up and you will be obliged to surrender your driving licence to the investigating officer (Article 164, paragraph 1 of the WVW).
