Since the beginning of December the breathalyzer controls They are increasingly common on Spanish roads. With the arrival of Christmas, company dinners and the Constitution Bridge, traffic agents increase their vigilance due to the celebrations and the increase in displacements.
However, it is not difficult for there to be false positives in the breathalyzer and one of the causes of this may be the mouthwash. And it is that it is very frequent that mouthwashes have among their ingredients alcoholan amount sufficient to exceed the limit of 0.25 milligrams per liter.
Despite the fact that the mouthwash is not ingested, if a control is carried out, the expired air does contain alcohol and this can give a positive result in the breathalyzer used by Civil Guard agents in these measurements.
What to do if this happens?
If this happens, the test should be repeated a second time And if it continues to test positive, it is necessary to perform a contrast test in the hospital, since a blood test is carried out.
Despite the fact that in a first test the alcohol rate can be quadrupled, in the second the problem usually disappears, since the effect of the mouthwash remains for a maximum of 10 or 15 minutes. Therefore, it is possible that we can get rid of the blood test and the time involved.
