What Is a DWI in New York?

A DWI (Driving While Intoxicated) generally occurs when a person operates a motor vehicle with:

• A blood alcohol concentration (BAC) of 0.08% or higher, or
• Evidence of impairment by alcohol or drugs

DWI is considered a criminal offense and carries serious penalties, especially for repeat offenders or cases involving high BAC levels (Aggravated DWI).

Possible consequences of a DWI include:

• Jail time, particularly for repeat or aggravated offenses
• Substantial fines and court fees
• License suspension or revocation
• Mandatory alcohol or substance abuse programs
• Installation of an ignition interlock device
• A permanent criminal record

A DWI conviction can also increase insurance rates and impact employment or professional licensing.

What Is a DWAI in New York?

DWAI (Driving While Ability Impaired) is typically charged when a driver’s ability to operate a vehicle is impaired by alcohol or drugs, but the BAC is below 0.08%.

DWAI is generally considered less serious than DWI. However, it still carries significant penalties and should not be taken lightly.

Possible consequences of a DWAI include:

• Fines and surcharges
• Points on your driver’s license
• Shorter license suspensions
• Mandatory alcohol or drug education programs
• Probation in certain circumstances

Although penalties may be lighter than DWI, repeat DWAI offenses can lead to more severe charges and long-term consequences.
