DUI vs. DWAI at the Larimer County Courts
What is the Difference Between Driving Under the Influence and Driving While Ability Impaired in Fort Collins?

Driving Under the Influence and Driving While Ability Impaired, C.R.S. 42-4-1301, are both charged at the Larimer County Courts in Colorado when a person’s ability to drive is affected by alcohol, marijuana, and/or another substance.  While the two offenses are charged under the same statute and are both misdemeanors, they are also charged based on different levels of intoxication.  This generally makes DWAI a less severe offense than DUI.  Whether you have been charged with DWAI or DUI, don’t wait, and contact a top DUI lawyer today to represent you at the Larimer Couty Courts.

3. DUI vs. DWAI in Loveland and Estes Park

Both Driving Under the Influence / DUI and Driving While Ability Impaired / DWAI are charged in Loveland and Estes Park for driving while intoxicated due to alcohol, marijuana, and/or a controlled substance.  One of the primary differences between these two charges is that DWAI is charged when that substance affects your ability to drive “to the slightest degree.”  DUI is instead charged when your driving ability is far more substantially impaired.  Additionally, if your BAC is between 0.05 and 0.08, you will be charged with DWAI, regardless of how badly impaired your ability to drive was.  Similarly, a BAC over 0.08 will instead result in DUI charges, even if your ability to drive was not substantially impacted.
