DUI (Driving under the influence) Laws:
DUI charges are usually based on a person's BAC or blood alcohol concentration and may be determined by the administering of a breath, blood or urine test (which is usually conducted if drugs are suspected).
The Legal Limits:
A person's BAC is the percentage amount of alcohol found in his or her bloodstream.
Most states have a legal limit of 0.08 for citizens over age twenty-one.
The Penalties for Drunk Driving:
The punishments vary significantly from state to state. All drunk driving offenses carry potential jail sentences. However, most first offenders are given lesser punishments, such as driver's license restrictions, fines, mandatory attendance of drunk driver's education classes, mandatory attendance of "Alcoholics Anonymous" meetings or alcohol counseling, community service, or probation.
