Frequently Asked Questions About Rancho Cucamonga DUI Lawyers

How much does a Rancho Cucamonga DUI lawyer cost?

DUI defense fees vary depending on the attorney, the complexity of the case, prior DUI convictions, whether an accident occurred, and whether the case proceeds toward trial. Prospective clients should ask about the total fee, what services are included, and whether additional court or expert costs may apply.

How long do I have to fight my driver’s license suspension after a DUI arrest in California?

California DMV states that you generally have 10 days to request a DMV administrative hearing after receiving the suspension or revocation order.

Is the DMV DUI case separate from the criminal DUI case?

Yes. California DMV describes the administrative license action as separate from the criminal court case. The DMV proceeding addresses your driving privilege, while the criminal case determines whether you are guilty of the DUI offense.

Where are DUI cases heard in Rancho Cucamonga?

Criminal cases for the Rancho Cucamonga area are handled through the Rancho Cucamonga District of the Superior Court of California, County of San Bernardino, located at 8303 Haven Avenue.

Can a DUI charge be dismissed in California?

A DUI charge can potentially be dismissed depending on the facts and evidence. An attorney may examine issues involving the traffic stop, arrest, chemical testing, field sobriety testing, constitutional rights and the prosecution’s ability to prove each required element. The outcome depends on the individual circumstances of the case.

Can I still drive after being arrested for DUI?

That depends on the specific circumstances and any applicable DMV action. California DMV states that DUI arrests can trigger an Administrative Per Se suspension or revocation process, which is separate from the criminal case.

Do I need a DUI lawyer for a first offense?

You are not legally required to hire a lawyer, but a first DUI can still involve both criminal and DMV consequences. A DUI attorney can review the evidence, explain potential consequences, handle court proceedings, and advise you regarding the DMV process.

What happens if I refuse a breath or blood test?

Refusing or failing to complete a required chemical test can result in separate DMV consequences. California DMV states that refusal can lead to suspension or revocation of driving privileges, depending on the circumstances and prior history.

Can a Rancho Cucamonga DUI lawyer help with a DMV hearing?

Many DUI defense attorneys handle both the criminal case and DMV administrative proceedings. When hiring a lawyer, it is worth specifically asking whether the firm’s representation includes the DMV hearing and whether it will handle the hearing separately from the court case.
