What Is the Difference Between DUI, DWAI, and DUID in Fort Collins, Colorado?

Under C.R.S. 42-4-1301, Colorado treats impaired driving in tiers based on the level of impairment:

  • DUI (Driving Under the Influence): driving while substantially incapable, whether mentally or physically, of operating a vehicle safely due to alcohol, drugs, or both. A blood alcohol content (BAC) of 0.08 or higher is also treated as DUI.
  • DWAI (Driving While Ability Impaired): driving while affected to the slightest degree by alcohol or drugs. A BAC of 0.05 or higher can support a DWAI charge.
  • DUID (Driving Under the Influence of Drugs): impaired driving caused by marijuana, prescription medication, or other drugs. Colorado law allows a permissible inference of impairment at 5 nanograms or more of delta 9-THC per milliliter of blood.

Penalties depend on the charge and your history, and they can include:

  • Jail time: possible even for a first offense
  • Fines and court costs: which add up quickly
  • Probation and community service: with alcohol or drug education and treatment
  • License consequences: a separate DMV process can lead to suspension or revocation
  • Ignition interlock: often required after certain violations

Repeat offenses, high BAC levels, or an accident involving injury can increase the charge level, and a fourth lifetime offense can be charged as a felony.
