It is possible that the Intoxilyzer 8000C or roadside screening device can fail. The roadside screening devices commonly fail due to mouth alcohol detection.
For example, if an individual has had something to drink within the last fifteen minutes, or have had something to smoke – a cigarette – in the last six minutes, this can cause the roadside screening device to malfunction.
However, since it is only used as a screening device, it is important that we also make sure that the Intoxilyzer 8000C at the station is operating properly. This involves not only looking at the test records from your test, but also from test records and results from other tests of people who have had their tests taken around yours.
