Being pulled over for a suspected DUI is nerve-wracking, and drivers know that a conviction means big life changes. So to avoid it, drivers might refuse a blood test, which legally, the driver can do.

However, if a police officer has reasonable suspicions that you might be under the influence, the officer can get a warrant, at which point you must submit to a blood test. If your DUI charges had questionable circumstances, hire an Arizona DUI attorney to represent your case.

Why Drivers Might Delay a Blood Test

When you get behind the wheel of a car in Arizona, you submit to the laws and regulations of such activity. One law is that you must drive responsibly, which means not drinking and driving. So when an officer pulls you over and asks for a blood test and you know you've been drinking, sometimes delaying that test can be helpful.

The longer that you delay the blood test, the more likely you'll be to sober up in that time, making the blood alcohol content lower. If the officer smells alcohol on your breath, you're slurring your words, you fail a field sobriety test or there are other indicators of driving under the influence, the officer could obtain a warrant for the blood test.

Arizona DUIs and Blood Testing

The fourth amendment of the Constitution protects you from unlawful search and seizure. That applies to both your vehicle and your person, which means your blood is protected by the law.

This means that a police officer cannot randomly submit you to DUI tests. There must be signs of drinking and driving before the officer can make you take any tests. These signs might include:

  • Slurred speech
  • Smelling like alcohol
  • Bloodshot or glassy-looking eyes
  • Struggling with fine motor skills
  • Problems with balance
  • Confusion
  • Aggressive behavior

When a driver admits to drinking alcohol before driving - even if it's within moderation - this can also give the officer cause to test you. Be very careful about what you say during a traffic stop to avoid this common trap.

Signs of Drinking and Driving That Give Officers Cause to Test
Physical Signs Slurred speech, Bloodshot or glassy-looking eyes, Problems with balance
Motor Skills Struggling with fine motor skills
Behavioral Signs Confusion, Aggressive behavior
Mental State
Sensory Indicators Smelling like alcohol
Admission of drinking alcohol before driving - even if it's within moderation - this can also give the officer cause to test you
