The Laws On Consent And Rights In California DUI Arrests

In California, getting pulled over for a traffic infraction can be a scary experience. Even for a minor offense like a speeding ticket, no one loves getting into problems with the law. Even worse is getting pulled over for driving while intoxicated (DUI). Driving while intoxicated is not only very dangerous, but it can also be very embarrassing.


However, in addition to your DUI in Los Angeles, refusing to submit to a chemical test may result in other consequences. So, can authorities force you to take a breathalyzer test in California? How about consent laws? Can refusal lead to more penalties?

Let's look at what our Los Angeles DUI lawyers have to say about it:

California's Chemical Testing Consent Law

Given that you are aware of your right to be free from arbitrary searches and seizures under the Constitution, you may want to refuse to submit to a chemical test administered by the police. This is accurate, but it's a little more complicated than what movies and TV shows portray. You may be required to submit to chemical testing by law enforcement due to a legal concept known as "implied consent."


By using and driving your vehicle on the state's roads and highways, all drivers have implicitly consented to chemical testing, according to the implied consent regulation. Essentially, your agreement to chemical testing is inferred by operating a vehicle. You must comply with this requirement on your subsequent trip to the DMV.


The police cannot physically force you to submit to a chemical test, but you cannot opt-out of it either. Therefore, your choices in this scenario are merely for the type of testing you will submit to (i.e., a breathalyzer test, a blood test, or a urine test).


The California Vehicle Code states that the authorities must provide you the option of doing a breathalyzer test and drawing blood. So if one of those choices isn't available, you'll have to accept the alternative. Likewise, you might have to provide a urine sample for analysis if neither of the two is possible.

What Are the Consequences For Refusing A Breathalyzer Test In California?


Depending on your driving history and history of DUIs, the specific consequences for refusing to take a breathalyzer test or another type of chemical testing after being detained may differ. For example, a driver with a recent DUI on their driving record will be subject to harsher penalties than a first-time offender.

  • The most minor penalties apply if you have never been charged with a DUI before. However, if you are found guilty of the DUI, you will have your license suspended for a year and could also face additional required fines and jail time.

  • If you refuse to take a breathalyzer test and have been convicted of a DUI once during the last ten years, you will face the same penalties as above, but your license will be suspended for two years rather than one.

  • In the same way, if you have had two or more DUI convictions in the last ten years, your license will be taken away for three years.

In addition to your history of DUIs, your license status may also impact the suspension of your license. For example, your license suspension might be extended if it has already been suspended, even if you have no prior DUI convictions.


Your initial suspension had to have occurred within the previous 10 years and be connected to a refusal to submit to chemical testing. Call us to arrange a free case review if you declined chemical testing; our prescreened DUI defense attorneys in Los Angeles can assist.

You Can Still Be Found Guilty Of A DUI In Your Refuse A Breathalyzer

Because they are aware that a breathalyzer test will be used to show their intoxication, some drivers refuse to take it. However, you must realize that declining to take the test would not exonerate you from the DUI allegations.


It is unnecessary, but the findings of a post-arrest breathalyzer test would surely aid the prosecution in getting your conviction. Even without a breathalyzer test, you might still be charged with DUI and found guilty. Even worse, you will be subject to further fines if you refuse to take the test.


Before making an arrest, police officers could also request that you take a breathalyzer test. This breathalyzer test is different from the testing done after an arrest. The pre-arrest breathalyzer can be refused, but the post-arrest chemical testing cannot.


You will still be charged with refusing to submit to testing even if the prosecutor decides to withdraw your DUI charges due to a poor case without a post-arrest breathalyzer test or other chemical testing.

There is no simple solution to this problem. Charges for the DUI, charges for refusing to submit to testing, or even both may be brought against you. Please contact a prescreened criminal defense attorney in Los Angeles immediately if you declined a breathalyzer test.

Official California State Bar Lawyer Referral Service

Established in 2005, 1000Attorneys.com is a California State Bar–certified Lawyer Referral and Information Service, operating under LRIS Certificate No. 0128, accredited by the American Bar Association, and independently listed as a LawHelpCA Verified Resource.

Certified referral services exist to promote public protection, allowing consumers to bypass self-serving and misleading attorney advertising

Our role is to connect Californians with reputable, vetted, independently licensed counsel through a regulated, certified channel.

 

We do not advertise on behalf of any law firm, do not auction inquiries to multiple competing attorneys, and do not engage in advertising-based or pay-to-play rankings.

 

While our primary focus areas are California employment law and personal injury matters, our referrals extend to many additional practice areas.

 

Each match is based on the legal issue presented, jurisdiction, statute-of-limitations considerations, and the attorney's licensure and experience profile.

Why Lawyer Referrals Matter in California

The California State Bar investigates thousands of attorney misconduct complaints each year.

 

Verifying that an attorney holds an active license is necessary but not sufficient — licensure alone does not capture disciplinary patterns, practice-area depth, or fit for a specific legal matter.

 

A State Bar Certified LRIS operates under defined statutory authority — Business and Professions Code § 6155, Rule 3.800 of the California Rules of Court, and the State Bar's Minimum Standards for a Lawyer Referral Service.

 

Non-certified matching platforms and lead-generation services are not authorized to operate under this framework.

As part of our referral process, we review publicly available licensure and disciplinary records and consider substantive practice experience in the area at issue.
