Defines the terms "impaired" and "intoxication" for the purposes of the vehicle and traffic law

This bill (S 5875) defines two key terms in New York's vehicle and traffic law: "impaired" and "intoxication." It states that "impaired" occurs when a driver's physical or mental abilities are affected by any substance, even slightly, while "intoxication" is a more severe state where a driver cannot safely operate a vehicle. The bill also adds a limited defense for drivers claiming an allergic reaction or medical emergency caused their condition, but this defense does not apply if the substance involved is listed in Public Health Law §3306. This definition change directly affects drivers charged with driving under the influence (DUI) or similar offenses.
