Drunk Driving Charges We Defend

Drunk driving charges can take several different forms. Some cases stay at the misdemeanor level, while others move into felony territory based on prior offenses, injury allegations, or elevated BAC results. The classification often determines how it moves through court and what consequences you face on both the criminal and administrative side.

 

The lawyers at Frank & Juengel Law Group P.C. help with a variety of cases, including:

DWI/DUI Arrests in St. Louis

Most DWI cases in Missouri start with a traffic stop or an accident investigation. Officers then decide whether to make an arrest based on observations like driving behavior, performance on field sobriety tests, or results from breath or blood testing. 

 

A BAC of 0.08% or higher can create a legal presumption of intoxication, but that result still depends on how the test was conducted and whether the equipment and procedures meet required standards. We regularly defend cases such as:

 

  • Traffic stop arrests based on alleged lane violations, speeding, or other driving conduct 
  • Checkpoint arrests, where officers screen drivers for signs of impairment 
  • Accident-related arrests where alcohol is suspected after a crash 
  • Cases built on breath or blood test results 
  • Cases where no chemical test exists, and the state relies mainly on officer observations 

High BAC and Felony DWI Defense

Some drunk driving charges involve high BAC DWI defense. These cases often carry enhanced sentencing exposure and additional court-ordered conditions. High BAC cases typically involve breath or blood results well above the legal limit, often 0.15% or higher. 

 

Missouri law also increases penalties based on prior offenses, which classifies drivers as prior offenders, persistent offenders, or aggravated offenders, depending on their record. Our attorneys handle cases involving:

 

  • Elevated BAC results that lead to enhanced sentencing exposure 
  • Repeat DWI charges under Missouri’s prior offender statutes  
  • Felony-level DWI cases tied to prior convictions or aggravating factors 
  • Cases involving allegations of injury or property damage connected to driving behavior 

DWI License Suspension and Revocation Issues

A drunk driving case in Missouri does not end in criminal court. The Missouri Department of Revenue handles administrative license suspensions, revocations, and reinstatement requirements after certain DWI-related arrests. The Department of Revenue also controls whether your driving privileges are suspended or revoked, and that process often begins quickly after a DWI arrest.

 

A BAC test result at or above the legal limit can trigger an administrative suspension. Refusing a chemical test can also lead to a separate revocation, even if your criminal case is still pending. These administrative actions operate independently from the court case, which means you can face license consequences even before a conviction occurs. Our lawyers help with:

 

  • Administrative suspensions based on alleged BAC test results 
  • Refusal-related revocations under Missouri’s implied consent laws 
  • Hardship and limited driving privilege eligibility during suspension periods 
  • Reinstatement requirements through the Missouri Department of Revenue, including fees and compliance steps 

 

Driver’s license issues often require separate attention from the criminal case, especially when deadlines for hearings or reinstatement steps are involved. The attorneys at Frank & Juengel Law Group P.C. can help you understand what’s required for driver’s license reinstatement after DWI.

How We Attack Drunk Driving Evidence

Our St. Louis DUI/DWI drunk driving defense attorneys review whether the stop was lawful, whether testing was reliable, whether officers followed required procedures, and whether the prosecution can prove impairment beyond a reasonable doubt.

Drunk driving cases in St. Louis, MO, depend on whether law enforcement followed the required legal standards at every stage of the stop, investigation, and testing process. Even when the state has chemical test results or officer observations, those pieces of evidence must still comply with Constitutional rules before they can be used in court. We evaluate the case step by step to identify where the evidence can be challenged or limited. This includes:

  • Traffic stops: Traffic stops must be supported by reasonable suspicion under Fourth Amendment standards. Officers need a lawful reason to initiate a stop, such as an observed traffic violation or specific driving behavior. Without that justification, the stop itself can be challenged, which can affect all evidence gathered afterward. 
  • Field sobriety testing: These tests are based on NHTSA guidelines, but real-world conditions and officer execution can significantly affect the results. Weather, road conditions, physical limitations, and deviations from instructions can all influence performance and interpretation.
  • Chemical testing: Chemical testing depends on proper calibration, handling, and timing. Breath test machines must be maintained correctly, and blood samples must follow strict chain of custody procedures. Errors in collection, storage, or analysis can impact the reliability of reported BAC results, including rising BAC scenarios. 
  • Other evidence: Video evidence, reports, and officer testimony must be consistent across the record. Body and dashcam footage can be compared directly with written police reports and courtroom testimony. Differences between recorded evidence and officer descriptions, as well as statements made before or after arrest, can create inconsistencies that affect the prosecution’s credibility. 
  • Testing refusal: Refusing a chemical test triggers administrative consequences, but only if officers advise you of the refusal consequences and document the process correctly. Errors in the advisement or documentation can affect whether the administrative suspension imposed by the Department of Revenue is valid.
