Just as New York law punishes drivers for driving while intoxicated (DWI) by prohibiting a blood alcohol level in excess of .08 percent, the state also provides penalties for impaired driving. A motorist will be considered to have been impaired by alcohol consumption if a chemical test reveals a blood alcohol content of between .07 and .08 percent. A blood alcohol content of between .05 and .07 percent will be considered relevant evidence, but not presumptive proof of impairment by alcohol.
