The DWI Law in New York
In New York the offense is DWI, and the limit is 0.08; driving while ability impaired (DWAI) is charged from 0.05.
Driving in New York is consent to a breath or blood test when an officer has cause to suspect DWI; the license case that follows a refusal or a failed test is run by the DMV, separately from the criminal case.
For charging and sentencing, New York counts prior offenses within 10 years.
Who Makes DWI Arrests in Lockport
The Niagara County Sheriff's Office and the agency that reports for Lockport (filed by the FBI as Lockport Police Department) make the DWI arrests in and around Lockport.
Together, the eight agencies in Niagara County with all twelve months of 2025 on file reported 2,830 arrests to the FBI that year, all offenses together; the FBI's count for Niagara County does not break DWI out.
