DUI Sentencing Guidelines

For a standard first offense with a BAC between 0.08% and 0.19%, penalties may include up to 90 days in jail and/or fines up to $1,000, underscoring the potential severity of a first conviction. If the BAC is > 0.20%, a more severe mandatory minimum of 10 days in jail applies, reflecting the increased risk posed by highly intoxicated drivers under the existing DUI sentencing guidelines. In addition to criminal penalties, the court will typically order the completion of an alcohol education program or substance abuse treatment to address the underlying behavior and reduce the likelihood of recidivism.

While sentencing in D.C. is not purely a rigid BAC-tiered system, higher BAC readings consistently result in more severe penalties, aligning with the intent of the DUI sentencing guidelines to punish higher levels of impairment more strictly. Higher BAC levels typically translate into longer potential jail terms, increased fines, and longer administrative license suspensions imposed by the Department of Motor Vehicles. Furthermore, a history of high BAC readings in past incidents, even if the current offense is a first conviction, may be considered an aggravating factor by the judge, potentially triggering enhanced penalties and more intensive monitoring requirements.

A second DUI within 15 years carries a mandatory minimum 10-day jail term and significantly higher fines, ranging between $2,500 and $5,000. The administrative license revocation can last one year or more, and the installation of an ignition interlock device (IID) for a period is often mandatory upon license reinstatement, reflecting the strict DUI sentencing guidelines. For a third or subsequent offense within that 15-year period, the minimum jail term rises to 15 days, with fines ranging from $2,500 to $10,000. The courts retain the authority to impose much longer incarceration periods, especially if the offender's history or current offense involves serious aggravating circumstances, effectively treating repeat impaired driving as a serious public safety threat.

When DUI leads to injury or death, the charges escalate dramatically from simple misdemeanors to felony-level offenses with correspondingly severe prison sentences, reflecting the catastrophic consequences of impaired driving. Cases involving minor injuries may remain as misdemeanors, potentially resulting in up to 180 days in jail and $1,000 in fines, but serious bodily injury resulting from impaired driving can result in felony charges, carrying multi-year prison terms and substantially higher fines. DUI-related deaths may result in charges such as vehicular homicide or involuntary manslaughter, carrying years of imprisonment and substantial fines, along with the automatic and permanent revocation of the driver's license upon conviction, reflecting the maximum penalties reserved for the most grievous driving offenses under the DUI sentencing guidelines.

IIDs are generally required for all repeat DUI sentencing offenders and may also be ordered for first-time offenders with high BAC readings or those who refused to submit to testing, subject to limited statutory exceptions. The device, which prevents a vehicle from starting if the driver’s breath alcohol exceeds a preset limit, must be installed and maintained at the offender's expense. Tampering with, bypassing, or failing to use an IID as ordered is taken extremely seriously and can result in significant additional criminal penalties, including fines, new jail time, and extensions of the mandatory license suspension period, effectively punishing any attempt to circumvent the court's order.

Defense counsel may contest the accuracy of breathalyzer or blood test results by scrutinizing the equipment's calibration records, the officer's adherence to required testing protocols, and the chain of custody for any blood samples, all of which are critical elements of the case. Furthermore, the defense may challenge the initial traffic stop itself, arguing a lack of reasonable suspicion or probable cause to initiate the stop or arrest, which could lead to the suppression of all evidence gathered thereafter. A thorough examination of the Field Sobriety Tests (FSTs), including the defendant's physical condition and the environment where the tests were performed, is also a common element of a robust defense strategy.
