As a licensed driver in the state of North Carolina, you need to educate yourself on the rules of the road to prevent any brushes with the law. One of the most prominent issues that you should know about is how DWI cases are handled in North Carolina. Below are some of the frequently asked questions about breathalyzer tests for DWI, along with their corresponding answers.

Is a breathalyzer test the only way to measure a driver’s blood alcohol concentration (BAC) levels?

A breathalyzer test is the most common method of measuring BAC, but it’s not the only one available. Law officers who stop drivers on suspicion of DWI can also seek a warrant to draw and test someone’s blood in order to determine a driver’s BAC level.

Are breathalyzer tests reliable?

The results of a breathalyzer test have been ruled as admissible evidence in a DWI case. However, the test is not as accurate as a blood test, and the method is not infallible. Certain elements, such as machine malfunction, and different room and body temperatures, can affect the device’s reliability.

Can the results of breathalyzer test be disputed?

Yes, and if warranted, most DWI attorneys will attempt to do so. Your driving privileges, money, reputation, and future are all on the line with a DWI arrest. An experienced DWI lawyer can help you challenge the validity of your breathalyzer test if something was done wrong.
