Why You Need a Portable Breathalyzer

After you’ve been drinking, it’s critical to make sure your breath alcohol concentration (BrAC) is zero before getting behind the wheel. Even slight impairment can risk your safety or that of other people on the road. It’s easy to think you’ll “just know” whether or not you’re safe to drive, but using a reliable breathalyzer is the only way of being certain. You should never get behind the wheel if you have been drinking, the stakes are high as you risk the lives of not only yourself and your passengers, but anyone else on the road with you.

A portable breathalyzer is also helpful if you want to avoid drinking too much at a gathering. By testing yourself periodically during an event, you can make sure you’re drinking at a reasonable pace and avoid suffering the consequences of binge drinking. Responsible drinking can help you avoid hangovers and drunken behavior (but remember, it is unsafe to drive at any level of impairment, even if you only had one drink).

Know Your Breath Alcohol Concentration (BrAC)

Blood alcohol concentration (BAC) is highly variable and depends on multiple factors including weight, food consumption, and the type of alcohol consumed, it can be hard to predict when your BAC will return to zero after drinking. Tools like a BAC calculator may provide some guidance, but the only way to be confident you’re safe to drive is to test your breath alcohol concentration (BrAC) with a reliable breathalyzer.

Colorado’s Department of Transportation has carried out studies on how breathalyzers can impact people’s drinking and driving habits. They found that when given a portable breathalyzer, the percentage of drivers who were “confident in their ability to drive after a few drinks” went down significantly. Participants became more aware of the legal limits, and reported being less likely to depend on their own judgment of their ability to drive safely. CDOT hopes if more people feel comfortable using personal breathalyzers, they will stay off of the roads after drinking.
