Driving Under the Influence

It is unlawful for any person who is under the influence of intoxicating liquor or any drugs to drive or be in actual physical control of any vehicle. There are many conditions that can affect your ability to drive even after one drink; for example, body weight, emotional state or physical condition. The best rule to follow is still: If you drink, do not drive.

When you apply for and accept the privilege to drive a vehicle in Arizona, you give consent to test for blood alcohol concentration or drug content (BADC) if you are arrested for driving while under the influence of intoxicating liquor or drugs (DUI). This is known as the Implied Consent Law.

When a law enforcement officer has reason to believe you have been driving while under the influence, the officer will request that you submit to a BADC test of your blood, breath, urine or other bodily substance to measure the amount of alcohol or drugs present in your bloodstream.

DUI Penalties

If you are stopped for driving under the influence and a test shows that you have an alcohol concentration of 0.08 percent or more (0.04 in a commercial vehicle requiring a commercial driver license), or if a blood alcohol or drug test result is not available, you will lose your driving privilege on the spot. In addition you will be required to complete alcohol or drug screening before you can obtain a restricted permit or reinstate your driving privilege.

It should be understood that you may be found guilty of driving while intoxicated or while under the influence of any drug or its metabolite even though the blood alcohol concentration was less than 0.08 percent. If you are under 21, your license may be suspended if there is any alcohol concentration.

If you refuse to submit to or do not successfully complete any tests when you are arrested for driving under the influence, you will automatically lose your driving privilege for 12 months or 24 months for a second refusal within 84 months. In addition you will be required to complete alcohol or drug screening before you can obtain a restricted permit or reinstate your driving privilege.

In addition to any criminal penalties imposed by the court for a second or third offense DUI violation, your driving privilege will be automatically revoked.

Certified Ignition Interlock Device

A certified ignition interlock device is a breath alcohol testing instrument connected to the ignition and power system of the vehicle. The driver blows into the device before attempting to turn the ignition. If the driver’s alcohol level is above a certain level, the vehicle will not start. While the vehicle is operating, the driver must blow into the device at random intervals.
