What is Considered an Underage DWI in Missouri?
In Missouri, an underage DWI occurs when a person under the age of 21 operates a motor vehicle with a blood alcohol content (BAC) of 0.02% or higher. Unlike adult DWI laws, Missouri’s underage DWI statutes are designed to be stricter because of the heightened risks associated with young drivers and alcohol consumption.
Key points to note:
- Zero-tolerance policy: Missouri enforces a zero-tolerance standard for drivers under 21. Even a small amount of alcohol can trigger an underage DWI charge.
- Impairment: A driver may also be charged if they are under the influence of alcohol, drugs, or controlled substances, regardless of BAC.
- Aggravating factors: In some cases, additional penalties apply if the underage driver is involved in an accident, refuses a BAC test, or has prior alcohol-related offenses.
Because underage DWI charges carry serious consequences for your driving privileges and criminal record, hiring a St. Louis underage DWI attorney early in the process can make a significant difference.
Missouri Underage DWI Penalties
Penalties for underage DWI in Missouri can vary depending on the circumstances of the offense and any prior convictions. Common consequences include:
- License suspension: First-time offenders may face a driver’s license suspension of up to 90 days, while repeat offenders could lose driving privileges for a year or longer.
- Fines: Monetary fines can range from several hundred to over a thousand dollars.
- Alcohol education and treatment programs: Courts often require participation in alcohol education or substance abuse programs.
- Community service: Many underage offenders must complete a designated number of community service hours.
- Probation: Depending on the case, probation may be imposed, which can include strict conditions and regular reporting to a probation officer.
It’s important to understand that even a first-time underage DWI can impact your insurance rates, future employment opportunities, and college admissions. Having a knowledgeable St. Louis underage DWI attorney can help reduce or even avoid some of these consequences.
Legal Defenses for Underage DWI Charges
Experienced attorneys at JMH Law Firm, LLC know that underage DWI charges are not always straightforward. Several legal defenses may apply, including:
- Challenging BAC accuracy: Breathalyzer and blood test results can be challenged if the equipment was faulty or improperly maintained.
- Improper traffic stop: If law enforcement lacked reasonable suspicion to stop the vehicle, evidence obtained may be inadmissible.
- Field sobriety test issues: Poorly administered field sobriety tests or improper officer procedures can be contested.
- Medical conditions or medications: Certain conditions or medications can affect test results, providing a possible defense.
Our team will examine every aspect of your case to identify weaknesses in the prosecution’s evidence and pursue the most effective defense strategy.
