Key Concepts of an Arizona DUI:
- Actual physical control of a vehicle means you have control of a vehicle and that control presents a real danger to you or others. Under this theory, you could be charged with DUI even if you weren’t actually driving. Proving actual physical control is fact specific. Evidence that is considered when determining actual physical control includes:
- whether the vehicle was running;
- whether the ignition was on;
- where the ignition key was located;
- where and in what position you were found in the vehicle;
- whether you were awake or asleep;
- whether the vehicle’s headlights were on;
- where the vehicle was stopped;
- whether you had voluntarily pulled off the road;
- time of day;
- weather conditions;
- whether the heater or air conditioner was on; and
- whether the windows were up or down.
- Impairment to the slightest degree means your ability to operate a vehicle was diminished due to drugs or alcohol. Any impairment will satisfy this DUI element. There are no specific alcohol or drug concentration thresholds. This means you can be charged with DUI even if your alcohol concentration is below the legal limit of 0.08.
- Alcohol concentration is primarily determined through the analysis of blood or breath samples. Generally, an alcohol concentration of 0.08 or higher within two hours of driving qualifies as a DUI. For commercial drivers, an alcohol concentration of 0.04 or higher within two hours of driving is enough to be convicted of DUI.
- Drugs or their metabolites can also be the basis of an Arizona DUI charge. Qualifying drugs include marijuana, cocaine, methamphetamines, and other controlled substances. The full list of drugs that can result in a DUI is extensive. Most DUI drugs fall into the following general categories: cannabis, dangerous drugs, narcotic drugs, and prescription-only drugs.
