In New York State, you can be arrested for any of these offenses: aggravated driving while intoxicated (Agg-DWI), driving while intoxicated (DWI), driving with a blood alcohol content of .08 percent or more (.08 BAC), driving while ability impaired by a drug (DWAI-drug), driving while ability impaired by alcohol (DWAI), or driving under the combined influence of alcohol and drugs.
Blood alcohol content (BAC) is the percentage of alcohol in your blood and is normally determined by a chemical test of breath, blood, urine or saliva. A BAC of more than .05 percent is legal evidence that you are impaired, a BAC of .08 percent or higher is evidence of intoxication, and a BAC of .18 percent or more is evidence of aggravated driving while intoxicated.
Many people think chemical test evidence is required to prove you were intoxicated or impaired. However, the testimony of a police officer about the way you drive, your appearance and behavior when arrested can provide enough evidence to convict you, even without a chemical test.
If you are found guilty of any alcohol or drug-related violation, the court must revoke or suspend your driver license when you are sentenced. Even if the court allows you to continue driving for 20 days, your driver license will be taken immediately.
