Rancho Cucamonga DUI Attorney

Charged with a DUI?

Driving under the influence (DUI) of alcohol or drugs has become a nationwide problem – as well as a top priority for law enforcement agencies. In San Bernardino County and the surrounding communities of Southern California, there is a great deal of attention placed on arresting, prosecuting, and convicting motorists who get behind the wheel while impaired.

Being charged with a DUI can be a very serious matter, especially if this is not the first time you've been charged with a DUI. The circumstances of every DUI arrest vary, but if your blood alcohol level is over .08% at the time of arrest, meaning there are .08 grams of alcohol or more for every 100 milliliters of blood in your body, you can be charged with a DUI.

If you or a loved one have been charged with driving under the influence, contact our DUI attorneys in Rancho Cucamonga today to learn more about your options.

DUI Penalties in California

In California, defendants are generally charged on two different counts, a charge for driving under the influence and a charge for driving with a blood alcohol level of .08% or higher, which initiates a DMV hearing in which your license can be suspended.

Some factors that can influence penalties include:

  • The charge involved (misdemeanor or felony DUI)
  • A driver's blood alcohol content (BAC)
  • Prior DUI convictions
  • DUIs resulting in injury or death
  • DUIs involving child passengers

If convicted, a DUI can bring with it harsh penalties such as:

  • License suspension
  • Steep fines
  • Jail time
  • Community service
  • Mandatory completion of DUI programs
  • Required installation of an Ignition Interlock Device

It is possible to face some or all of these consequences depending on the circumstances of your case and whether you have prior DUIs, so it is crucial to have solid representation. Contacting an attorney immediately should be your first step after being arrest for drunk driving.

It is important to remember that any of these penalties can threaten one's personal and financial well-being, which is why working with an experienced Rancho Cucamonga DUI lawyer is essential.

Why Do Some DUIs Get Dismissed?

Driving under the influence is a serious matter in California. With so many individuals relying on driving as a means of transportation, it is important to keep the roads safe. For those charged with a DUI, the consequences can be dire and follow you long after the incident. However, you may have heard that some DUI cases get dismissed. A DUI charge can be dropped numerous ways.

No Probable Cause for Traffic Stop

In order for the authorities to pull you over, they need probable cause for believing you are driving under the influence. If you can prove that the police officer did not have a probable cause for the stop, a judge can potentially drop the DUI charge. Usually, a police video can show whether the stop was founded or not.

Defective Breathalyzer

When an officer believes you are driving under the influence, he or she will administer a breathalyzer test. This test consists of you breathing into a machine that estimates how much alcohol is in your system. However, like all machines, the test is not foolproof. Sometimes, if not adjusted appropriately, the breathalyzer can improperly calibrate and show your blood alcohol as being higher than it really is. If the machine was faulty and inaccurately recorded the results, you can potentially have your case dismissed.


Sometimes, police officers present a situation that inevitably makes you look guilty. For example, let us say that you were drunk and decided to sleep it off in your car until you were sober. However, a cop comes over and forces you to drive home. As soon as you do, he or she arrests you for a DUI. This situation is an example of entrapment. Because of the misleading information and requests, you can potentially have your case dismissed.
