Where were you arrested? A DUI is a state offense, but each jurisdiction handles them slightly differently.

What are the methods used to measure BAC?

Determining your blood alcohol concentration is often an integral part of any investigation into allegations of driving under the influence. There are a number of ways in which this can be measured, as is explained in this article. Various samples from your body can be used to obtain your BAC, including the following:

  • Breath
  • Blood
  • Saliva
  • Hair follicles
  • Urine

A Breathalyzer is often the first port of call for determining an individual's BAC. However, these devices are not always accurate. If the device has not been adequately maintained, its reading may not be valid. This is important to bear in mind if faced with charges relating to drunk driving as an invalid reading might negate the charges against you.

In some situations, officers might perform a blood draw in order to obtain your BAC. This is a less common method, used more if someone refuses other methods. It is also occasionally employed in the aftermath of serious accidents where the subject of the test is left unable to submit to other tests.

Personal BAC-testing devices are also available, as we have discussed previously. However, their accuracy varies, so they may not be the best means of determining whether you are safe to drive. If you wish to avoid drunk driving charges, the best option is usually not to drive at all if you have been consuming alcohol.

If you are suspected of drunk driving, you could face a lengthy investigation and serious penalties if convicted. An attorney can help you sort through the details of your case and may be able to determine the best course of action to take in order to preserve your reputation and avoid conviction.
