Arrested for DUI in Arizona but Not Charged?
Here's What Happens Next.
One of the most common phone calls we receive goes something like this:
"I was arrested for DUI a few weeks ago, but I still haven't been charged. Did they decide not to file the case?"
The answer is: maybe—but don't assume that's the case.
In Arizona, it is very common for someone to be arrested for DUI, released from custody, and then wait weeks or even months before criminal charges are filed.
Understanding why this happens—and what you should be doing while you wait—can help you avoid costly mistakes and reduce some of the uncertainty.
Why Wasn't I Charged Immediately?
Many DUI cases involve a blood draw instead of (or in addition to) a breath test.
Unlike a breath test, blood samples must be analyzed by a crime laboratory. Depending on the laboratory's workload, staffing, and the complexity of the testing, toxicology results can take several weeks or even several months to be completed.
Many Arizona law enforcement agencies and prosecutors prefer to wait until they have those results before filing criminal charges.
This often occurs because prosecutors want all of the available evidence before making charging decisions.
It is also common in cases involving:
Drug-related DUI investigations
Multiple substances
Serious collisions
Property damage
Aggravated assault allegations
Criminal damage allegations
Felony DUI investigations
These investigations frequently take longer because officers are gathering additional evidence beyond the blood test.
Does This Mean My Case Has Been Dropped?
Not necessarily.
There are several possible outcomes after a DUI arrest.
Charges are eventually filed.
This is the most common outcome. Once prosecutors receive the laboratory results and complete their review, they may file criminal charges.
Prosecutors decide not to file charges.
Sometimes the evidence is insufficient, laboratory results do not support impairment, or prosecutors determine they cannot prove the case beyond a reasonable doubt.
Additional investigation is requested.
Occasionally, prosecutors ask law enforcement to gather more information before deciding whether charges should be filed.
Unfortunately, there is no way to determine which outcome will occur simply because time has passed.
How Long Can It Take?
Every case is different.
Some cases are filed within a few weeks.
Others may not be filed for several months after the arrest.
The timeline often depends on:
Crime laboratory turnaround times
Complexity of the investigation
The prosecutor's workload
Whether additional evidence is needed
Waiting several months does not necessarily mean the case has gone away.
What Happens With My Driver's License?
This is where many people become confused.
Your criminal case and your driver's license are two separate matters.
Even if criminal charges have not yet been filed, you may still have deadlines involving the Arizona Motor Vehicle Division (MVD).
Depending on your circumstances, you may be facing an Administrative Per Se suspension or another administrative license action.
These proceedings have their own deadlines and procedures that are completely separate from the criminal court process.
Missing those deadlines can have serious consequences for your driving privileges.
What Is an Administrative Per Se Suspension?
Arizona law allows the MVD to suspend a driver's license under certain circumstances after a DUI arrest.
This administrative process is separate from whether you are ultimately convicted of DUI.
In many cases, drivers have the right to request a hearing to challenge the suspension.
Because strict deadlines apply, it is important to understand your rights as soon as possible after your arrest.
How Will I Know If Charges Are Filed?
If criminal charges are filed, you will typically receive notice through the mail.
Depending on the circumstances, you may receive:
A summons to appear in court
A notice of an arraignment
Other court documents
It is important to make sure your mailing address is current.
Missing a court notice can lead to missed hearings, additional legal complications, and in some cases, a warrant being issued.
You can also monitor Arizona court records to determine whether a case has been filed.
Should I Just Wait?
Waiting without understanding your situation can create unnecessary stress.
While you are waiting, it may be helpful to:
Keep copies of all paperwork you received at the time of your arrest.
Calendar any MVD deadlines.
Make sure your mailing address is current.
Monitor court records periodically.
Consult with an attorney if questions arise.
Can an Attorney Help Before Charges Are Filed?
Absolutely.
Many people assume they should wait until they receive a court date before speaking with an attorney.
In reality, there are several ways an attorney may be able to assist before charges are ever filed.
Depending on the circumstances, an attorney may:
Explain the criminal process.
Advise you regarding the MVD and Administrative Per Se process.
Represent you at MVD hearings.
Monitor court filings.
Submit public records requests.
Answer questions about employment applications, professional licensing, fingerprint clearance cards, immigration concerns, or other issues affected by a pending investigation.
Be prepared to immediately respond if charges are filed.
Having someone monitoring your case can provide peace of mind during what is often a very uncertain period.
Frequently Asked Questions
Can I still drive?
That depends on your license status and any MVD actions that have been taken. The answer is not determined solely by whether criminal charges have been filed.
Could I never be charged?
Yes. Some investigations never result in criminal charges. However, you should not assume this simply because several weeks or months have passed.
Should I check the court myself?
You can. Many people also choose to have an attorney monitor their case to ensure that filings are not missed.
Should I hire an attorney now or wait?
Every case is different. Some people prefer to wait until charges are filed, while others appreciate having legal guidance during the waiting period—especially if they have questions about the MVD process, employment, licensing, travel, or other issues related to the investigation.
Final Thoughts
Being arrested but not immediately charged can be one of the most frustrating parts of a DUI investigation. The uncertainty often leaves people wondering whether they should prepare for court or simply move on.
The reality is that delayed charging is common in Arizona DUI cases, particularly when blood testing is involved.
Understanding the process—and staying informed while you wait—can help you avoid missed deadlines and be prepared for whatever comes next.
If you have questions about a pending DUI investigation, the Administrative Per Se process, or whether charges have been filed, an experienced Arizona DUI defense attorney can help you understand your options and guide you through each stage of the process.
