Understanding DUI Charges in Indiana
Driving under the influence (DUI), also known as operating while intoxicated (OWI) in Indiana, is a serious criminal offense. These charges can have lasting effects on your record, finances, and freedom.
What Qualifies as DUI, DWI, and OWI Under Indiana Law?
Indiana law uses several terms for impaired driving, including DUI (Driving Under the Influence), DWI (Driving While Intoxicated), and OWI (Operating a Vehicle While Intoxicated). All refer to operating a motor vehicle while your abilities are impaired by alcohol, drugs, or controlled substances. Even prescription medication can result in an OWI charge if it affects your ability to drive.
An Indiana DUI Lawyer can explain the specifics of your charges and the evidence involved.
Felony vs Misdemeanor DUI Charges
A misdemeanor DUI generally applies when a driver is caught operating a vehicle with a blood alcohol concentration (BAC) of 0.08% or higher, but no one is injured, and the driver has no prior DUI convictions within the last seven years. Penalties for a misdemeanor DUI can include fines, license suspension, probation, community service, and even jail time.
A DUI becomes a felony when more serious factors are involved. This includes situations where the driver has previous DUI convictions, causes an accident resulting in serious injury or death, drives with a suspended license, or has a minor in the vehicle. Felony DUI charges carry significantly harsher consequences, such as longer jail or prison sentences, steeper fines, and extended license suspensions.
What Are the Penalties for DUI in Indiana?
In Indiana, the penalties for driving under the influence (DUI), also referred to as Operating While Intoxicated (OWI), can vary significantly depending on the circumstances of the offense, including the driver’s blood alcohol concentration (BAC), prior convictions, and whether the incident resulted in injury or death.
Indiana law is harsh on DUI offenders, aiming to deter impaired driving and ensure public safety.
First DUI Charge
The penalties for a first DUI conviction can include fines, probation, mandatory alcohol education programs, and a suspended license.
For a first DUI with a BAC between 0.08% and 0.15%, you may face Class C misdemeanor charges. Penalties can include a fine of up to $500 and a jail sentence ranging from a few days to a maximum of 60 days.
If the BAC is above 0.15% or the driver operates the vehicle in a manner that endangers a person, the offense escalates to a Class A misdemeanor, potentially leading to jail time of up to 1 year and fines of up to $5,000.
Repeat Drunk Driving Conviction
Repeated DUI offenses within 5 years increase penalties significantly. A second DUI offense can lead to a Level 6 felony charge, with harsher fines, longer jail time, and the possibility of a suspended license for a period ranging from 180 days to 2 years.
For individuals with two or more DUI convictions within the past 10 years, the offense may be charged as a Level 5 felony, which carries a prison sentence of 1 to 6 years and up to $10,000 in fines.
Driver’s License Suspension for Refusing a Chemical Test
Refusing to submit to a breath or blood test can trigger immediate license suspension under Indiana’s implied consent laws. This administrative penalty is separate from any criminal charges. Losing your license can disrupt your work and daily life. An experienced DUI Attorney can challenge the suspension and seek to restore your driving privileges.
Can I Refuse a Breath Test (Breathalyzer) in Indiana?
Indiana’s implied consent law means that refusing a breath, blood, or urine test can have immediate consequences. Refusal often results in automatic license suspension, even before your case goes to court. This administrative penalty is separate from any criminal charges you may face.
A knowledgeable Indiana DUI Defense Lawyer can challenge the procedures used during your arrest and the validity of the license suspension. With the right legal guidance, you have a stronger chance of keeping your driving privileges and protecting your future.
If you find yourself facing an OWI charge or license suspension, it’s critical to seek help from an experienced DUI Attorney who understands Indiana law and can fight for your rights from the very beginning.
How a DUI Attorney Can Challenge Evidence
In every DUI case we tackle, a comprehensive review of the prosecution’s evidence is paramount. Our legal team meticulously examines the data, focusing on breathalyzer and field sobriety test procedures, to identify any potential flaws or inconsistencies. This detailed scrutiny allows us to challenge the credibility of the evidence presented against you, aiming to fortify your defense with precision.
Expert Breath Test Defense from a Nationally Recognized Specialist
Charles Rathburn, founder of Rathburn Law, is not just any Indiana DUI Defense Lawyer. He is a recognized authority on breath testing devices, including the Alco-Sensor III and DataMaster. His technical knowledge allows him to challenge the accuracy and reliability of breath test results.
Police officers must ensure that the breathalyzer equipment is properly calibrated and maintained. A DWI attorney can challenge the results if the breath test machine was not used properly or the police officer was not adequately trained.
Certified Phlebotomist to Challenge Blood Test Evidence
Blood and urine tests are often central to DUI cases. Charles Rathburn is certified in phlebotomy and laboratory procedures. This unique skillset allows him to scrutinize lab results and expose mistakes in the collection, storage, or analysis of your samples. Not every DUI Attorney can offer this level of scientific review.
Field Sobriety Testing
A DUI attorney can challenge field sobriety test evidence by questioning how the tests were conducted and whether the police officer followed proper procedures.
Field sobriety tests, such as walking in a straight line, standing on one leg, or following a pen with the eyes, depend heavily on the officer’s judgment. An attorney may point out that poor lighting, uneven ground, bad weather, medical conditions, or nervousness could have caused the driver to appear impaired even when they were not.
The attorney may also examine the officer’s training and experience to show that the test results are unreliable. If the police officer failed to give clear instructions, didn’t account for the driver’s health issues, or deviated from standard testing guidelines, the evidence can be challenged or even thrown out. By exposing these weaknesses, a DUI lawyer can raise reasonable doubt about whether the test results accurately reflected impairment.
