DUI – DWI Defense Lawyer in Phoenix Area

Jonathan L. Warshaw



Arizona law prohibits a person from driving a vehicle while they are under the influence of alcohol or drugs. If you have been charged with a DUI or DWI, a Gilbert DUI attorney is your most likely shot at avoiding excessive fines, jail time, loss of license, and more. At the Law Office of Jonathan L. Warshaw, I had years of experience as both a police officer and a prosecutor—experience which you can now use to your benefit.


The legal limit for most drivers is a blood alcohol concentration of 0.08 percent BAC. Arizona has a zero-tolerance policy for drivers under the age of 21. Underage drivers can be charged if they have any amount of alcohol in the body above 0.00 percent BAC. For drivers of commercial vehicles, the legal BAC limit is 0.04 percent. Even if a driver tests below the BAC limit, they may still be charged if they are under the influence of alcohol or any substance if the driver is impaired to any degree.

I am proud to bring a number of benefits to all of my clients, including:

  • Low-cost payment plans & options.
  • Free consultations.
  • Former police officer and prosecutor.
  • Thousands of cases dismissed.
  • Over 15 years of experience.

If you have been charged with a DUI, my firm can help you to navigate what happens after. Contact us today to learn more about the services I offer.


Police and law enforcement test a driver’s impairment in a variety of ways. Some of the information used by police to determine intoxication is from observation of the driver before and after being pulled over. This includes observation of how the person was driving, including speeding, failing to stop for signals, or swerving between lanes.

After a driver is stopped, an officer may observe the driver’s actions, including slurred speech, and the smell of alcohol. An officer may also request the driver participate in a series of standardized field sobriety tests (SFSTs).

Officers may also utilize chemical testing, and present this evidence in court to show that the driver was per se intoxicated (above a certain level, like .08). This includes a breath test, blood test, and in some cases a urine test. Chemical tests involving the suspect’s urine or blood can detect not only the levels of alcohol in the body, but also the presence of drugs. Even if the drug is legal, such as medication, a DUI can be charged if the driver is impaired.


At the Law Office of Jonathan L. Warshaw, I constantly seek to protect your right to continue owning and operating a vehicle, as well as to keep you out of jail. I have years of experience handling these types of cases, first as law enforcement, then as a prosecutor, and finally as a highly skilled Gilbert DUI defense lawyer. I am proud to provide my clients with the comprehensive, knowledgeable counsel they need to succeed.
