What Happens After a DUI Arrest in Diamond Bar?

CA DUI Law allows an officer to arrest you even if you BAC is below .08, or if you aren't tested at all. Police officers can do this because they when they rely on other methods to tell if you are impaired, likely using field sobriety tests, then arrest you based on your performance.

Once this happens, the CA legal system starts moving towards both a license suspension and criminal charges. In most DUI cases, here's how things will progress:

  1. Suspension: Your license suspension can start the minute the officer arrests you – you will be given a 30-day, temporary license, and your permanent license will be confiscated by the officer. Meanwhile, the police are contacting the DMV about your DUI arrest, which updates their records to show your license as suspended.
  2. Arraignment: While under arrest, you will go to court, and a prosecutor will give you a formal notice of the charges you're facing.
  3. DMV Hearing: Separate from the criminal charges, you'll need to set up an administrative hearing with the DMV within 10 days to fight the suspension.
  4. Pretrial Motions: Often, at the same time as your arraignment, the court will set conditions for your release, pending a trial. Meanwhile, your Diamond Bar DUI defense attorney will file pretrial potions, likely including some to suppress unlawfully collected evidence, and a "blood split" motion to have an independent lab examine your blood sample.
  5. Negotiations With the Prosecutor: Inbetween pretrial motions, your DUI defense attorney will negotiate with the Diamond Bar prosecutor to try and secure a favorable deal before a trial. But if you do have to fight the charges in a trial, your attorney should be crafting a strategy now.
  6. Criminal Trial: Your case probably will not go to trial, but just in case it does, our team always crafts a trial-ready defense.
  7. Sentencing/Sealing: Depending on how your case turns out, you may face penalties. However, if you are found not guilty or enough time has passed, we may be able to help you clean your record.

Our DUI legal experts can provide you with advice on the best way to move forward, on both the criminal defense and administrative side. No matter where you are in your case, our team has the knowledge to guide you forward!



Defending Against Diamond Bar DUIs: Criminal Cases vs. DMV Hearings

Diamond Bar, CA, DUI charges are always a two-pronged challenge: The criminal case and the license suspension. Different CA organizations cover each of these aspects, but when you hire the right attorney, they can defend you in both cases.

Here are things to watch out for with both cases, and ways we defend your freedom and license:

Diamond Bar, CA, DUI Criminal Charges

Allegedly violating DUI laws will result in criminal charges. To fight them, you'll have to go through CA courts.

Criminal cases, including DUIs, all follow the same basic process – first, you're arrested. Second, you're informed of the charges at an arraignment. Third, you go through pre-trial motions and negotiations. And finally, if it comes to it, a trial.

At the Law Offices of David S. Chesley, we build your defense and push back against the allegations. We'll deconstruct the traffic stop, poke holes in the subjective analysis of the officer, look for weaknesses in the breathalyzer test, and search for other witnesses or evidence that can show you are not guilty.

The vast majority of our DUI clients in Diamond Bar do not receive any jail sentence. For several cases, we'll get the prosecutor to reduce the charges, frequently to a wet reckless, exhibition of speed, or reckless driving charge. We'll alsowork out probation over jail or prison time.

Diamond Bar, CA, DUI License Suspension

On the other side of a Diamond Bar DUI charge is the DMV and your license suspension. This suspension doesn't wait for your criminal case, and to fight it, you'll need to request an administrative hearing within ten days of your arrest.

The criminal charges are not always relevant in the DMV hearing. In fact, your license can still be suspended even if you do not receive a criminal conviction. Instead, the outcome of the DMV hearing hinges on whether or not you were rightfully arrested, if your BAC was at or above 0.08, the legal limit, or, if you refused to blow, whether or not you were properly informed of the consequences. At the Law Offices of David S. Chesley, we'll challenge the legitimacy of the stop, the arrest, and the BAC reading.

If it's been more than ten days after your arrest, though, you're out of luck. Outside of rare cases, you don't get another chance to set up that hearing. This is why it's critical to contact a Diamond Bar DUI defense attorney as soon as you can after an arrest.



DUI Punishments in Diamond Bar

CA DUI criminal penalties can be harsh – even for the ones considered misdemeanors, you could still end up with a year in jail, or six months for a first offense.

DUI Manslaughter (Felony) 4, 6 or 10 Years Up to $10,000

You'll also be facing significant collateral consequences, such as more expenses on your insurance and roadblocks when applying for professional licenses.

After the Case: Expungement/Sealing

After the case, regardless of the outcome, you'll want to get back to life as normal, before the charges. Unfortunately, your arrest and/or criminal record keeps coming up and getting in your way. Depending on your case outcome, you may be eligible to either expunge or seal your records. A DUI defense attorney can help you out here, too, and give you an opportunity to clean your record.
