Driving under the influence, more commonly known as drunk driving or driving while intoxicated, is a heavily punishable criminal offense in Tucson, Arizona. The state considers DUI a “violent crime” and results in harsh punishments, even for first offenders.
ARS § 28-1381 defines a DUI offense as being in physical control of a vehicle while under the influence of intoxicating liquor, drugs, vapor-releasing substance, or a combination of these substances that can impair a driver at even the slightest degree. More specifically, people are considered intoxicated if they have a blood-alcohol content (BAC) level of 0.08% or higher. If they drive a vehicle within two hours of exceeding the minimum BAC, they can be subject to a DUI charge, lose their driver’s license, and serve jail time.
Not everything is black and white, however, and every DUI case has different circumstances. If you or someone you love gets a drunk-driving charge, you’ll need solid DUI defense strategies and an experienced DUI defense attorney to defend your rights.
Here are examples of DUI defense options that you can use depending on the circumstances surrounding your case. Note that DUI defenses aren’t a remedy to dismiss your case instantly. Rather, they are a good starting point to build your case, so having an experienced DUI defense lawyer on your side is vital.
Let’s get started.
Police officers use breathalyzers to determine if a driver has exceeded the acceptable intoxication threshold. These devices analyze the amount of alcohol vapor in the lungs and determine a person’s BAC level. However, the value that breathalyzers provide is an indirect measurement of a person’s blood alcohol level. Moreover, they can give false positives due to several factors:
If any of these scenarios apply, you can add this argument to your DUI defense strategies.
Like with the breathalyzer results, you can challenge the integrity of your blood tests if you have reason to believe your sample may have been contaminated, tampered with, or improperly handled, such as it wasn’t stored properly or it took hours before your blood sample was tested in a lab. BAC findings are often evidence in drunk-driving cases, so contesting its accuracy and reliability is also one of the most common DUI defenses.
Most people behave exactly as you would expect of a drunk person. Hence, police officers conduct FST to verify intoxication. The three standardized FSTs are the one-leg stand, walk-and-turn, and horizontal gaze nystagmus test.
The first thing you should know is you’re not required to do an FST in Arizona. You have the right to refuse, which you should do if circumstances aren’t in your favor:
If you agree to perform FSTs, your performance can be used against you. Suppose you complied with the tests and didn’t do so well. You can counter with these DUI defenses:
The second counter argument brings us to another of the most common DUI defenses you can use, not because it is a loophole but because many officers violate this rule.
Traffic law states that officers can only pull over a vehicle if they have a reasonable and articulable basis of cause. This means they can only stop a moving car on the road and check for the possibility of a DUI if:
Police officers only need minor violations like broken tail lights to pull over a vehicle legally. Only then can they investigate you for possible intoxication. But if you didn’t break any laws and they have no reasonable cause for suspicion, your DUI defense attorney can build a case for dismissal.
This is one of the textbook DUI defenses attorneys can use: prove that the officers performed an unlawful stop because they had no basis to stop your vehicle. If the court agrees, any evidence the police obtains after pulling you over – an over 0.08% breathalyzer result or failed FSTs – will become inadmissible under the exclusionary rule. The prosecutor will have no choice but to drop the charges against you.
The Fourth Amendment of the US Constitution protects everybody from unreasonable searches and seizures. The state bears the burden of proving they have legally obtained evidence that a crime has been committed.
This applies to getting pulled over for suspected drunk driving. The burden of proof lies on the police officers, and they cannot pull you over simply because they have a hunch that you’re intoxicated. Watch out for unreasonable causes for stopping your car; they are some of the best DUI defense strategies you can use to dismiss your DUI charge:
Arizona’s law explicitly defines DUI as driving and having physical control of a vehicle while under the influence of alcohol, thereby becoming a threat to others. So, if you weren’t driving or in control of a vehicle at the time of arrest, the state doesn’t have a case against you.
For example, if you sat inside your car with the engine running to turn on the air conditioning, fully intending to wait until the effects of the alcohol wore off, you can make a case before the jury that you weren’t driving and aren’t guilty of DUI. This is one of the most common DUI defense options your defense attorney can use. However, you may need solid evidence, like interior dash cam footage, to strengthen your case.
Here are more examples of circumstances that can benefit from this argument:
It’s difficult to disprove “actual physical control of a vehicle” in court. The prosecution will use the following to prove that you were:
