What can happen under Georgia law if I refuse to take a chemical or field sobriety test when I am suspected of DUI?

Like many other states, Georgia has an implied consent law, which means that if you are suspected of driving while intoxicated, you are agreeing that you will undergo blood, urine, or breath tests for the purposes of measuring your BAC. 
If you refuse to take one or more of these tests, and are arrested as a result, you can face a harsher sentence.
