What is "DWI-DUI?"

DWI is defined as “driving while Intoxicated.”  DUI is defined as “driving under the influence” of alcohol or drugs

All 50 States, the District of Columbia, and Puerto Rico have by law set a threshold making it illegal to drive with a BAC of .08 g/dL or higher.  DWI is defined as “driving while Intoxicated.”  This means having a BAC of 0.08%. Washington D.C. has a Zero Tolerance for drivers under the age of 21. This means that if you are under the age of 21 you are not allowed to have any measurable alcohol in your system's blood, breath or urine. ​The Washington D.C. DUI / DWI law also includes driving under the influence of controlled substances such as marijuana, cocaine, inhalants and other drugs. DUI is defined as “driving under the influence” of alcohol or drugs.  This can be applied even if your BAC is below 0.08% if it can be proved you are impaired.
