Compliance Checking blood alcohol and breathalyzer

ENIN November 2017

During an inspection, the police may conduct an alcohol test on drivers with a breathalyzer or breathalyser. If the test is positive, the driver is exposed to various penalties for driving while intoxicated.

The case of authorized control

There are two cases in which you will be compulsorily controlled:

  • during a serious breach of the Highway Code driving license suspension;
  • during a traffic accident causing personal injury.

Other cases in which the alcohol test can be performed (but are not required provided) are:

  • when the driver is involved in a traffic accident whatever its nature;
  • when the driver is presumed to be the author of an offense relating to the speed, seat belt or helmet.
  • when routine screening operation is conducted on the instructions of the public prosecutor or a police officer.

Flow of the alcohol test

The check is first carried out by means of a breath test which establishes a presumption of alcoholic state.

  • If you are asked to blow into a plastic bag ( "balloon"), there is a control to determine whether you are above or below 0.25 mg / L of expired air.
  • The agent can also use a breathalyser to obtain an indication of the level of alcohol content in the breath.

In case of positive test or refusal of the driver to submit to testing, further checks are carried out through a breathalyzer (or, alternatively, using a blood test) that precisely measure the level of alcohol per liter of blood. Depending on the test results, the security forces have the ability to proceed with the administrative holding your license.
