Ontario, CA, DUI Lawyer Traffic Stop Tips:

Most people don't plan to be pulled over, but knowing how to handle the situation is important for all Ontario, CA, residents. Here are four tips from a Ontario, CA, DUI Lawyer for you to use the next time a police officer stops you on the road:

Tip #1: Have Your Documents Ready
It's normal to be nervous after being pulled over and asked for your ID, registration, and insurance. If you're struggling to locate them and keep hold of them, the officer may think you're intoxicated. By following this tip, you avoid that risk.

Tip #2: If You or the Officer Smells Alcohol, Don't Speak
If there's a scent of alcohol on your person or in your vehicle, don't talk. You have the right to remain silent during any form of questioning. Protect yourself by keeping quiet until your lawyer arrives.

Tip #3: Refuse Voluntary Tests
In California, field sobriety tests are voluntary unless you are under the age of 21 or are on probation. You can still be arrested if the officer believes you've broken the law, but you're giving them less evidence this way. However, you can face consequences if you refuse a blood alcohol content test after you've been arrested.

Tip #4: Be Polite and Don't Argue
Refusing to cooperate with the police won't help — it will come back to bite you. You should be respectful for more than its own sake, though; it also helps your defense: By acting out or arguing, you are giving the police more evidence, which could contribute to their probable cause to arrest you.


What Happens After a DUI Arrest in Ontario?

California DUI Law allows an officer to arrest you without a BAC level over the limit, or even if you don't blow at all. Officers are able to arrest you this way because CA allows them to make subjective judgements, likely via field sobriety tests, then decide whether or not to arrest you based on how you do.

As soon as you're arrested, the CA legal system automatically begins the process for both a license suspension and criminal charges. After the arrest, be prepared for the following:

  1. Suspension: Your license suspension can go into effect at the time of the arrest – at that time, you will be given a 30-day, temporary license, while the officer will keep your regular license. While you're proceeding through the system, the police are informing the DMV about the arrest, at which point, you're officially facing a license suspension.
  2. Arraignment: After your arrest and before your release, you will go to court, and a prosecutor will announce what charges you're up against.
  3. DMV Hearing: While all of the criminal proceedings are going on, you'll need to start fighting for your license right away. This starts with arranging a DMV hearing, which you need to do within 10 days.
  4. Pretrial Motions: It's possible to be held in jail before your trial, but that's not very likely in DUI cases. While you're waiting for the trial, your Ontario DUI defense lawyer will file motions to strengthen your defense, such as ones to review the arrest footage, and a "blood split" motion to retest your blood sample.
  5. Negotiations With the Prosecutor: Inbetween pretrial motions, your DUI defense attorney will bargain with the Ontario district attorney to try and secure a favorable deal before a trial. But if the case goes to trial, your attorney should be building a defense now.
  6. Criminal Trial: Outside of extraordinary circumstances, it's rare for a DUI case to go to trial, but just in case it does, our team always crafts a trial-ready defense.
  7. Sentencing/Sealing: Depending on the outcome of your case, you may face some form of sentence. 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 guidance for any charge, on both the criminal defense and DMV side. Whatever stage in the process you're at, you can start with a call to our offices!



Ontario DUI Allegations and Criminal Cases vs. DMV Hearings

Ontario, CA, DUI charges include two separate fights: The criminal case and the administrative case. This will always require two separate defenses, but both cases can be fought by the same DUI defense lawyer.

Here are some things you need to know about both, and what our attorneys will do for your liberty and vehicular rights:

Ontario, CA, DUI Criminal Charges

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

Most of the steps in a DUI criminal case are identical to that of another criminal charge – arrest, arraignment, pretrial activity, and possibly trial.

At the Law Offices of David S. Chesley, we listen to your side of the story and attack the accusations. We'll debate the legality of the traffic stop, question the legitimacy of the officer's subjective observations, look for contaminations or errors in blood, breath, or urine tests, and look for witness testimony and other proof that can tell a different story.

With our defense strategies, we are almost always successful at protecting our Ontario, CA, clients from jail time. Commonly, we'll negotiate a plea deal to reduce the charges, typically to a wet reckless, exhibition of speed, or reckless driving charge. We'll also work out probation over jail or prison time.

Ontario, CA, DUI License Suspension

While it might be tempting to focus exclusively on the criminal case, you also need to consider the DMV and your license suspension. This suspension goes into effect regardless of where you're at in the criminal process, and to effectively 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 hearing is to determine if you were legitimately 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. These hearings have serious consequences that require an expert Ontario, CA, DUI lawyer to navigate. At the hearing, we'll argue over 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 request that hearing. This is why it's important to contact a Ontario DUI defense attorney without delay after the arrest.



Sentence You Could Face for a DUI in Ontario, CA

Ontario, CA, DUI criminal penalties can permanently affect your life – even though some are misdemeanors, you could still be sentenced to a year in jail, or six months for a first offense.

On this table, you can review the different penalties you could be looking to avoid, depending on the allegations you're facing:

DUI Criminal ChargeJail/Prison TimeFine

DUIs and Immigration

DUI immigration consequences can be devastating. On the bright side, most first-time DUIs at this time will not result in deportation. The bad news is that if certain circumstances apply, like DUIs causing injury or repeat offenses, you can qualify for deportation. What's worse, if H.R.875 passes, any DUI conviction will qualify an immigrant for deportation. For individuals working on the naturalization process, even if you aren't deported, it can count against your "good moral character," which you need to establish before becoming a citizen.

These accusations can be intimidating, but they are not the end. Your Ontario, CA, immigration lawyer can give you practical advice on what comes next. At the Law Offices of David S. Chesley, can provide assistance with all of your legal needs, not just against criminal accusations: We'll explore diversion programs to protect your record, fight to keep you in the country, and offer expert advice as you apply for citizenship.

After the Case: Expungement/Sealing

Whether you're found guilty or not guilty, it's natural to want to move on and leave this in the past. You'll find, though, that your arrest and/or criminal record won't go away on its own. Depending on your case outcome, there's a chance you're eligible to either expunge or seal your records. A Ontario, CA, DUI defense lawyer can help you with these processes, and give you an opportunity to clean your record.

DUI Defense Strategies in Ontario, CA

Every DUI case needs a defensive strategy, and our Ontario, CA DUI defense lawyers are here to help you find the right one. Choosing the correct defense for your particular circumstances is essential in finding the best possible outcome. Below are some of the most effective ones.

Challenge the Legitimacy of the Traffic Stop
If law enforcement made a mistake while conducting their investigation, we can challenge the evidence, and even the legitimacy of the case itself. This defense is effective if, for example, the officer did not observe you for the full 15-minute period required before asking you to take a breath test.

Show Issues With Chemical Tests
Chemical tests that measure the amount of alcohol in your blood, breath, or urine are strong evidence, but are not infallible. Our team will highlight the ways that these tests can give false readings, introduce alternative evidence when possible, and highlight any errors in the chain of custody.

Challenge Field Sobriety Tests
Field sobriety tests, like 'horizontal gaze nystagmus,' are a typical part of any traffic stop that turns into a DUI investigation. But these tests are subjective. Your local DUI lawyer will inspect any records of the test and look for expert analysis that will show your performance in a more favorable light.

Explain BAC With Medical Conditions
Maybe there were no mistakes with your blood, breath, or urine test, and your BAC was .08 or higher. While properly conducted BAC tests are hard to disprove, there are still ways to fight it. We can examine your diet and medical conditions to find alternative explanations.
