Which of the following factors can interfere with breath test results?

Consumption of certain food or beverages can indeed interfere with breath test results. This is because the presence of specific substances in the mouth can affect the accuracy of the reading. For example, consuming alcoholic beverages shortly before a breath test can lead to an elevated blood alcohol concentration (BAC) reading, even if the individual is no longer intoxicated. Additionally, some foods, particularly those that are fermented or contain trace amounts of alcohol, can also produce false readings. This interference occurs because the Intoxilyzer 9000 measures the amount of alcohol vapor present in the breath, which can be influenced by recent dietary intake. Understanding the impact of food and beverages is crucial for ensuring accurate and reliable test results.
