1. Refuse any field sobriety tests and breath test: If pulled over for suspicion of DUI, politely decline to take any roadside sobriety tests. These tests are not mandatory and are subjective in nature, meaning they can be used against you in court. 2. Invoke your right to remain silent: You have the right to remain silent during any police questioning. Make sure to invoke this right and do not answer any questions related to your alcohol consumption or the events leading up to your arrest. 3. Contact a lawyer: As soon as possible, contact a lawyer who specializes in DUI defense. They will be able to guide you through the legal process and help you build a strong defense. 4. Challenge the stop: In order for a DUI charge to be valid, the officer must have had a valid reason for pulling you over. If you believe the stop was made without probable cause, you can challenge it in court. 5. Challenge the test results: Breathalyzer and blood tests are not always accurate and can be subject to errors. If you believe your test results are inaccurate, you can challenge them in court.
