What Happens After a DUI Arrest in Diamond Bar?
CA DUI Law allows an officer to arrest you even if you blow below the legal limit, or if you aren't tested at all. Officers are able to arrest you this way because CA allows them to make subjective judgements, likely utilizing field sobriety tests, then make arrests based on your performance.
As soon as you're arrested, the CA legal system automatically begins the process for both a license suspension and criminal charges. You can expect the following steps to play out in your case:
- Suspension: Your license suspension can begin as soon as you're arrested – at that time, you will be given a 30-day, temporary license, while the officer will keep your regular license. Meanwhile, they are providing a record of the arrest to the CA DMV, which updates their records to show your license as suspended.
- Arraignment: After your arrest and before your release, you will go to court, and a prosecutor will tell you the exact laws you're charged with breaking.
- DMV Hearing: As soon as you're released from jail, you'll want to set up a DMV hearing within 10 days to protect your license.
- Pretrial Motions: In most DUI cases, you'll be released in some capacity pending a trial. In the meantime, your Diamond Bar DUI defense lawyer will file pretrial potions, likely including some to suppress evidence, and a "blood split" motion to have an independent lab examine your blood sample.
- Negotiations With the Prosecutor: While filing pretrial motions, your DUI defense lawyer will communicate with the Diamond Bar prosecutor to avoid a trial with a plea deal that protects you. But if the case goes to trial, your attorney should be preparing now.
- Criminal Trial: It's unlikely that your DUI case will go to trial, but we're prepared to defend your license and freedom if it does.
- 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 help you out, no matter where you are in the process, on both the criminal defense and DMV side. Whatever stage in the process you're at, give us a call so that we can help!
Defending Against Diamond Bar DUIs: Criminal Cases vs. DMV Hearings
Diamond Bar, CA, DUI charges include two separate fights: 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 some things you need to know about both, and ways we defend your freedom and driving privileges:
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 protect your rights and attack the allegations. We'll challenge the legitimacy of the traffic stop, argue against he officer's observations, look for weaknesses in the breathalyzer test, and see if there's anything the police missed that can show you are not guilty.
The vast majority of our DUI clients in Diamond Bar do not receive any jail sentence. In many cases, we'll work out a plea for reduced charges, frequently to a wet reckless, exhibition of speed, or reckless driving charge. We'll alsoavoid jail time with a probation sentence.
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 goes into effect automatically, and if you want to fight it, you'll need to request an administrative hearing within ten days of your arrest.
At the administrative hearing, you're not facing criminal charges. In fact, you can lose your license regardless of the outcome of the criminal case. 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 alcohol tests, whether or not you were properly informed of the consequences. When you hire us, we'll fight the legitimacy of the stop, the arrest, and the BAC reading.
Outside of that ten-day window, though, you'll likely have to endure the suspension. Outside of rare cases, you don't get a second chance to schedule that hearing. This is why it's crucial to contact a Diamond Bar DUI defense attorney as soon as you can after an arrest.
Diamond Bar DUI Sentences and Consequences
CA DUI criminal penalties can be harsh – while many are considered misdemeanors, they can still result in up to a year in jail, or six months for a first offense.

After the case, regardless of the outcome, odds are, you'll want to leave it in the past and move forward with your life. However, your arrest and/or criminal record doesn't go away easily.
