What Should I Do Immediately After Under the Influence DUI Arrest in DuPage County?
Illinois DUI defense attorneys explaining critical steps to protect your rights after Under the Influence DUI arrest.

What Should I Do Immediately After Under the Influence DUI Arrest?
The first 48 hours after your Under the Influence DUI arrest under 625 ILCS 5/11-501(a)(2) are critical for protecting your rights and building your defense against subjective impairment charges. Under the Influence DUI cases rely heavily on officer observations rather than scientific evidence, making your immediate actions even more important for preserving defense opportunities.
Taking the right steps immediately can challenge the officer's opinion about your impairment and protect your driving privileges, while mistakes during this time can strengthen the prosecution's case against you.
Immediate Actions After Under the Influence DUI Arrest
Under the Influence DUI arrests require specific immediate actions because these cases depend on the officer's subjective observations of your behavior and appearance.
Your first priorities should include:
- Contact an experienced Under the Influence DUI attorney immediately because these cases require specialized defense strategies that challenge officer observations rather than scientific evidence.
- Document everything about your physical condition including any medical issues, prescription medications, or fatigue that could explain symptoms the officer attributed to alcohol impairment.
- Record environmental factors that affected your field sobriety test performance, such as uneven pavement, poor lighting, inappropriate footwear, or weather conditions.
- Preserve witness contact information from anyone who observed your normal behavior before the traffic stop or during your interaction with police.
- Avoid discussing your case with anyone except your attorney, as statements about your drinking or behavior can be used against you even in casual conversations.
Critical details to document for Under the Influence DUI defense:
- Your exact physical condition including any illness, injury, or medical condition that could affect your balance, coordination, or speech patterns
- Prescription medications you were taking that might cause side effects officers mistook for alcohol impairment
- Food consumption including anything prepared with alcohol or fermented products that could create unexpected reactions
- Stress, fatigue, or emotional state that might explain behavior the officer interpreted as signs of impairment
License Protection for Under the Influence DUI
Under the Influence DUI arrests trigger the same automatic license suspension as other DUI types, despite the different evidence used for prosecution.
Critical license deadlines include:
- You have exactly 46 days from your arrest date to request an administrative hearing to challenge your license suspension
- Under the Influence DUI carries identical license penalties to other DUI charges, including 6-month suspension for first offenses
- Missing the hearing deadline results in automatic suspension even if your criminal case results in dismissal or acquittal
- Restricted driving permits may be available allowing essential driving during suspension if you meet specific requirements
Administrative hearing opportunities for Under the Influence cases:
- Challenge the officer's observations that formed the basis for your arrest and impairment determination
- Present medical evidence explaining symptoms the officer attributed to alcohol consumption
- Question field sobriety test administration and whether environmental factors affected your performance
- Attack constitutional violations during the traffic stop that could invalidate the entire arrest
Evidence Preservation for Under the Influence DUI Defense
Under the Influence DUI cases require immediate evidence preservation because they rely on subjective observations that can be challenged with proper documentation.
Evidence to preserve includes:
- Medical records and prescription information that could explain symptoms officers attributed to alcohol impairment
- Photographs of the arrest scene showing road conditions, lighting, and surface irregularities that affected field sobriety tests
- Witness statements from people who observed your normal behavior before the traffic stop
- Video evidence from nearby businesses or traffic cameras that might contradict officer testimony about your driving
- Documentation of medical conditions like diabetes, inner ear problems, or neurological issues that affect balance and coordination
Medical documentation priorities:
- Recent medical visits and any ongoing treatment that could explain your appearance or behavior
- Prescription medication lists including dosages and potential side effects that mimic alcohol impairment
- Blood sugar levels if you're diabetic, as low blood sugar can cause symptoms officers mistake for intoxication
- Any injuries or physical limitations that could affect your ability to perform field sobriety tests properly
Common Mistakes That Hurt Under the Influence DUI Cases
Under the Influence DUI defendants often make mistakes that strengthen the prosecution's case by providing additional evidence of impairment.
Mistakes to avoid include:
- Discussing your case on social media where prosecutors can find posts that contradict your defense strategy
- Driving during any license suspension which creates additional criminal charges and shows disregard for court orders
- Failing to follow up on medical issues that could provide alternative explanations for officer observations
- Missing court dates or deadlines which can result in warrants, additional charges, or loss of defense opportunities
- Talking to police or prosecutors without your attorney present, as these conversations rarely help your case
