If you've been pulled over for a DUI, a key to your defense may be challenging your field sobriety test.
With the option to refuse chemical tests for alcohol while pulled over, the field sobriety test may be the main piece of evidence against you when facing a DUI charge.
Here are three potential ways to contest a field sobriety test:

Many drivers who are subjected to a FST have a medical or psychological condition that will greatly skew the test results. Common problematic conditions include:
These are just three examples of potential challenges to field sobriety tests. If you are facing charges for driving under the influence, it's wise to contact an experienced DUI lawyer near you to see which defenses may work best for you.
