- C 0.02%

What is the difference between DWAI and DUI in Colorado?
- A DWAI is for drivers under 21; DUI is for drivers 21 and older
- B DWAI is impairment to the slightest degree; DUI is being substantially incapable of safe driving
- C DWAI is a parking offense; DUI is a moving offense
- D DWAI applies to drugs only; DUI applies to alcohol only
Show answer
B. DWAI is impairment to the slightest degree; DUI is being substantially incapable of safe driving
DWAI (Driving While Ability Impaired) means you are impaired to the slightest degree. DUI means you are substantially incapable of safe driving. Both can be proven by your driving behavior and field sobriety tests, not just your BAC.
