In New York, driving while intoxicated (DWI) is always a serious charge, but when your blood alcohol concentration (BAC) exceeds a certain threshold, the penalties increase dramatically. An aggravated DWI applies when a driver’s BAC is 0.18 percent or higher, which is more than twice the legal limit of 0.08 percent.
At O’Brien & Eggleston PLLC, our Albany criminal defense attorneys understand how a mistake can risk your license, reputation, and freedom. With more than 20 years of combined experience on both sides of the courtroom, our attorneys know how prosecutors build their cases and how to challenge them effectively.

The Legal Definition and Consequences of Aggravated DWI
An aggravated DWI is classified under New York Vehicle and Traffic Law §1192(2-a). The state treats this charge as a separate offense from a standard DWI because of the extreme BAC level and the higher potential risk to public safety.
For a first-time aggravated DWI offense, penalties can include:
- Up to one year in jail.
- Fines between $1,000 and $2,500.
- A minimum one-year license revocation.
- Mandatory participation in a Drinking Driver Program.
- Installation of an ignition interlock device on your vehicle.
If you are convicted of a second aggravated DWI within ten years, it becomes a Class E felony, carrying potential prison time, higher fines, and a longer revocation period. A third aggravated DWI within the same period is a Class D felony, which can lead to multiple years in state prison and permanent license revocation.
How an Aggravated DWI Differs from a Regular DWI
While both offenses involve operating a vehicle under the influence of alcohol, the key difference is the BAC level. A standard DWI requires a BAC of 0.08 percent or higher, while an aggravated DWI requires at least 0.18 percent. The higher reading leads the court to presume a greater risk to public safety and, therefore, imposes harsher penalties.
The difference also affects eligibility for specific programs. For instance, drivers convicted of an aggravated DWI may not qualify for a conditional license or a reduction to a lesser charge such as Driving While Ability Impaired (DWAI). This distinction makes it critical to work with an experienced attorney who can review every detail of your case to determine the best defense strategy.
Possible Defenses to an Aggravated DWI Charge
Even when the BAC number looks conclusive, there are often ways to challenge the evidence. Law enforcement must follow strict procedures during traffic stops, breath tests, and chemical testing. If any step is mishandled, the evidence may be inadmissible.
Common defenses include:
- Improper Stop: If police lacked reasonable suspicion to make the traffic stop, all subsequent evidence could be excluded.
- Faulty Testing Equipment: Breathalyzer machines require proper calibration and maintenance. Errors can produce inaccurate readings.
- Medical Conditions: Certain health issues, such as diabetes or acid reflux, can affect breath test results.
- Violation of Rights: If your rights were violated during arrest or questioning, your attorney can seek to suppress evidence.
Our Albany defense attorneys take a detailed approach to every aggravated DWI case, reviewing the arrest reports, video footage, and test results to identify weaknesses in the prosecution’s case.
The Impact on Your Future
Beyond legal penalties, an aggravated DWI conviction can have lasting consequences. It can appear on background checks, affect employment opportunities, raise insurance premiums, and damage your reputation in the community. Because aggravated DWIs are often viewed as more severe than other alcohol-related offenses, employers and licensing agencies tend to treat them more harshly.
This is why seeking immediate representation from a knowledgeable New York criminal defense attorney is crucial. Early intervention can make a significant difference in protecting your record and minimizing long-term harm.
