CENTRAL ISLIP, NY - August 13, 2026 - Motorists arrested for Driving While Intoxicated in New York can face conviction based on chemical test results alone, even when their driving appeared safe. Long Island DWI defense attorney Jason Bassett of the Law Offices of Jason Bassett, P.C. (https://jbassettlaw.com/vehicle-and-traffic-law-1192_2-driving-while-intoxicated-per-se/) has released guidance explaining how "per se" DWI charges work under Vehicle and Traffic Law Section 1192.2, what prosecutors must prove, the penalties involved, and the defenses that may apply.

Under New York Vehicle and Traffic Law Section 1192.2, a "per se" DWI charge is based entirely on a driver's Blood Alcohol Concentration, or BAC, rather than on observable signs of impairment. Long Island DWI defense attorney Jason Bassett explains that if a chemical test indicates a BAC of 0.08 percent or higher, operating the vehicle at or above that numerical limit is itself the completed criminal offense. "The result, not the driving, controls the charge," Bassett notes. "A person can be convicted even if they appeared sober and were driving safely, which is exactly what makes this offense different from charges that depend on observed impairment."

The 0.08 percent standard applies to individuals operating regular passenger vehicles, while commercial drivers face a stricter threshold of 0.04 percent. Long Island DWI defense attorney Jason Bassett points out that a separate rule applies to younger motorists under New York's Zero Tolerance Law, which addresses drivers under 21 who operate a vehicle with a BAC of 0.02 percent to 0.07 percent. This is a distinct offense handled differently from a Section 1192.2 charge.

Bassett explains how a per se charge differs from other alcohol-related driving offenses in New York. Driving While Ability Impaired under Section 1192.1 is a traffic infraction that relies on evidence of impairment, while common-law DWI under Section 1192.3 is based on an intoxicated condition shown through observed evidence. Aggravated Driving While Intoxicated under Section 1192.2-a is a per se offense based on a BAC of 0.18 percent or higher, carrying steeper penalties.

To secure a conviction under Section 1192.2, prosecutors must establish two core elements: that the defendant operated a motor vehicle, and that the driver's BAC was 0.08 percent or higher at the time of operation. "Impairment is not an element of this charge," Bassett observes. "These cases rely heavily on chemical test results, their admissibility, and their accuracy, which makes the testing process a cornerstone of any per se case." BAC can be measured through breath, blood, or urine tests, and New York law requires that the chemical test be administered within two hours of the alleged operation of the vehicle.

Attorney Bassett notes that the admissibility of BAC evidence depends on strict compliance with legal requirements. Breathalyzer devices must be regularly calibrated and maintained, the officer administering the test must be properly trained and certified, and the driver must generally be observed for at least 15 minutes before testing to rule out contamination. Any deviation from these protocols can raise doubts about the reliability of the results and may support a challenge to their admissibility.

The penalties for a Section 1192.2 conviction are significant even for first-time offenders. Bassett explains that a first-offense per se DWI is a misdemeanor carrying mandatory fines ranging from $500 to $1,000, a minimum license revocation of six months, and up to one year of potential jail time. Installation of an ignition interlock device is mandatory for all misdemeanor and felony DWI convictions, and convicted motorists must also pay a Driver Responsibility Assessment fee of $250 per year for three years, along with a mandatory surcharge and related fees.

Penalties escalate sharply for repeat offenses. A second DWI within ten years is classified as a Class E felony, with fines from $1,000 to $5,000 and up to four years of incarceration, while a third within ten years becomes a Class D felony, carrying fines from $2,000 to $10,000 and up to seven years. "Because a prior conviction can turn a new charge into a felony, reviewing a client's record carefully is essential before building a defense," Bassett emphasizes.

Attorney Bassett advises that a per se charge is not the same as a conviction, and that several defenses may apply. These include challenging probable cause for the traffic stop, questioning the accuracy and maintenance of the testing device, raising the rising BAC defense when there was a delay in testing, pointing to physiological factors that can cause falsely elevated readings, and identifying chain of custody issues. If a stop is found invalid, the field sobriety and chemical test results may be suppressed, which can lead to a reduced charge or dismissal.

The firm represents clients throughout Suffolk County courts and the surrounding Long Island area. Bassett brings more than 25 years of experience and a background that includes prior service as an Assistant District Attorney and Principal Assistant County Attorney, informing how he approaches each Section 1192.2 case.
