You can still be charged with a DUI.  Alcohol impacts everyone differently, so it is possible that your capabilities were intact.  However, under the NJSA 39:4-50 DUI law in New Jersey, you can be guilty of DUI if:   - You were under the influence of drugs or alcohol, or - If your BAC was over the 0.08% legal limit   Because of the way the law is constructed, the police do not technically have to prove you were impaired for the DUI charges to stick.  The 0.08% BAC measure provides a bright-line tool for police to use in DUI cases—primarily as a way to deter people from drinking and driving under any circumstances.
