Using the partition ratio, a breathalyzer can calculate a person’s BAC. Generally, a breathalyzer is able to measure BAC due to a chemical reaction. The alcohol vapor in a person’s breath reacts with an orange solution known as potassium dichromate. This color change creates an electrical current, which the breathalyzer can convert into a value to determine the BAC.

The myth of ‘sucking on a penny’ or keeping one under your tongue also does not hold any truth. Now, let’s talk about the smell that drinking imparts to your mouth, or what is commonly known as “alcohol breath”.

When the blood reaches the lungs and carries out the exchange of gases, alcohol is also passed over. Hence that “alcohol breath” is coming from your lungs, not the mouth. It’s important to remember that IIDs are set to prevent vehicle operation if the alcohol level in the breath is above a pre-set limit, often around 0.02% BAC (blood alcohol concentration).
