What To Do Immediately After A DUI/DWI Arrest
Taking immediate action after a DUI/DWI arrest helps protect your driver’s license and strengthens your legal defense:
- Request a hearing for administrative license suspension: Address your 7-day administrative driver’s license suspension promptly.
- Write down every detail of the traffic stop: Document the officer’s statements, road conditions, weather, field sobriety instructions and testing details while fresh in your mind.
- Avoid discussing your case: Do not talk about your arrest with friends, family or on social media platforms.
- Contact an experienced local DUI/DWI attorney: Schedule a consultation with defense counsel before your initial court appearance.
Following these steps provides your attorney with critical information needed to challenge police procedures and breath test results.

Fighting DUI/DWI Charges
Our legal team evaluates every stage of a DUI/DWI arrest to identify errors, technical flaws and constitutional violations. We examine multiple defense angles:
- Challenging the legality of the traffic stop: We review police dashcam and bodycam footage to verify whether the officer had reasonable suspicion to initiate a traffic stop.
- Challenging field sobriety tests: We evaluate whether the officer administered standardized field sobriety tests according to strict federal guidelines, accounting for medical conditions, physical injuries or poor road conditions.
- Challenging breath test results: We examine the EC/IR II breathalyzer machine’s maintenance logs, officer certification records and the mandatory 20-minute observation period.
- Challenging blood test results: We review chain of custody procedures, hospital draw methods and blood sample preservation under Virginia’s 3-hour testing rule.
- Challenging the arrest procedure: We confirm whether the officer established probable cause before placing you under arrest.
Drawing on over 35 years of Virginia DUI/DWI defense experience, attorney Mark B. Williams uses these investigative strategies to seek charge dismissals or reductions.
