Disposable alcohol testers, also known as disposable breathalyzers, are small, one-time alcohol testers that can be used to quickly measure the alcohol content in the breath. They are easy to use and are often sold in stores and online as a way for people to test for themselves whether or not they can drive safely.
In France, as in many countries, disposable alcohol testers are not legally recognized as evidence of drunk driving. This means that if you are arrested on suspicion of driving under the influence, the police are obliged to carry out an official alcohol test with professional alcohol meters.
While disposable alcohol testers can be a useful tool for determining breath alcohol levels, they are often less accurate than professional alcohol meters and cannot be used as evidence in court.
It is therefore important to remember that the only way to know for sure that you can drive safely is to avoid drinking alcohol before driving. Moreover, it is also recommended to carefully read the instructions for use of the disposable alcohol tester and perform the test properly to get the best result.
