Understanding Field Sobriety Tests in California

Top-Rated DUI Defense Attorneys in Los Angeles, California

Are you facing DUI charges in California? Don’t navigate the complexities of the legal system alone. At Law Offices of David S. Chesley, we specialize in providing aggressive and strategic defense for individuals charged with driving under the influence (DUI) in Los Angeles and throughout California. With our extensive knowledge of California DUI laws and dedication to client advocacy, we are committed to achieving the best possible outcome for your case.

Field sobriety tests (FSTs) are commonly used by law enforcement officers during DUI stops to assess a driver’s level of impairment. These tests are designed to detect signs of intoxication and provide probable cause for a DUI arrest under California Penal Code Section 23152. However, it’s essential to recognize that FSTs are not infallible and can be challenged with the right legal representation.

Common Types of Field Sobriety Tests

Horizontal Gaze Nystagmus (HGN) Test: This test measures the involuntary jerking of the eyes as they track a moving object. According to California law, officers may administer the HGN test to determine impairment by alcohol or drugs (California Vehicle Code Section 23152).
Walk-and-Turn Test: During this test, the driver is instructed to take nine heel-to-toe steps along a straight line, turn, and return in the same manner. Failure to maintain balance or follow instructions may indicate impairment (California Vehicle Code Section 23152).
One-Leg Stand Test: In this test, the driver must stand on one leg while counting aloud for a specified period. Swaying, hopping, or putting the foot down may suggest impairment and provide probable cause for arrest (California Vehicle Code Section 23152).

Challenging Field Sobriety Test Results

Know Your Rights

If you’ve been subjected to field sobriety tests during a DUI stop, it’s crucial to understand that these tests can be flawed. Factors such as weather conditions, medical issues, or officer bias may influence test results. Our experienced DUI defense attorneys meticulously review the circumstances surrounding your arrest to identify potential weaknesses in the prosecution’s case and develop a strong defense strategy.

If you are pulled over and asked to perform field sobriety tests, it’s essential to understand your rights under California law. You have the right to refuse to take these tests, although doing so may result in other consequences, such as the suspension of your driver’s license. Additionally, you have the right to request to speak with an attorney before submitting to any tests or answering any questions from law enforcement.

Our client faced multiple serious charges in Los Angeles County, including Penal Code § 211 (Robbery), § 245(a)(1) (Assault with a Deadly Weapon), and § 245(a)(4) (Assault with Force Likely to Cause Great Bodily Injury). Unlike a co-defendant represented by another firm who pled to a felony conviction with a "strike," our legal team pursued a different strategy. Through the submission of a comprehensive mitigation package to the District Attorney, we successfully negotiated a complete dismissal of all charges.
Our client faced serious charges under Penal Code section 211 for alleged felony robbery involving force and fear in Riverside County (Murrieta Court) . The prosecution argued that probation was not appropriate due to our client’s prior felony convictions in San Bernardino County, including a previous robbery in April 2021 and grand theft in November 2019. Despite the severity of these allegations, our legal team successfully demonstrated insufficient evidence during the preliminary hearing. As a result, all charges were dismissed. This outcome allowed our client to move forward without the burden of a new conviction.

Rodrigo L.

I left court yesterday with my last case being wrapped up. Two court appearances and that’s it. He represented me in a couple of different cases and was impressive to say the least. Always a phone call or text message away. Confident and aggressive when he needed to be. Calming and thorough when meeting with me. Attorney Chesley did exactly what he said he would and I got the results I needed. He seemed to know all the right people at the Temple Street courthouse. You can always get in contact with him quickly and he is a great lawyer. I highly recommend his legal services.
Ricardo Esteves

My brother was given a very caring attorney that was assigned to his case and we had very helpful case managers throughout the process. I strongly recommend David Chesley to anyone who is in trouble. I called in to get help on my brothers case and right away I liked their service. My brothers charges were eventually dismissed after the attorney got him into a program, now he could go on without the trouble of having anything on his record
Erica Geller

I retained Mr. Chesley and his firm and from the beginning they were extremely professional both in communicating the status of my case to me, explaining the situation as a whole, and just downright taking care of business. It was money well spent for a job well done. Thanks again to David and Melissa others that worked on my case. I recommend this firm to anyone in need of legal representation. Don’t just accept things the courts force on you, call this firm and protect yourself.
Elizabeth F.

I contacted Mr. Chesley and his firm because some unfortunate events had left me in a jam. Detectives were demanding I testify or be prosecuted for a crime I didn’t commit. (I wasn’t involved or even at the scene of the alleged crime when it supposedly took place.) Mr. Chesley explained to me that he had been through similar situations with his clients before and understood exactly what was going on. His response to what took place was nothing short of amazing. No matter how small my concern, Mr. Chesley addressed it in a timely manner. He advocated for what is right and empathized with me in dealing with the Court system. After meeting with the supervising D.A. and providing alibi evidence he was able to get me out the situation. I’m very grateful to have found him.
Leon Hanley

I hired David Chesley for my criminal defense in 2012. he was recommended to us for is success results and his low fees. David is very smart and his professional legal advice was honest & much appreciated during these stressful time. David’s knowledge, advice, and communication about what we were to expect was reassuring and beneficial to me. He charged me a reasonable flat rate and didn’t charge me any surprise fees. In my case David Chesley was able to negotiate with the prosecution attorney for the best result I could hope for. He had success at getting my criminal charges dismissed with the judges approval. You will not be disappointed if you hire The Law Offices of David S. Chesley.
Britanny Givens

David is very professional, yet very casual. Although it is typically not easy to speak straight up with an attorney, he is very easy to talk to. He replied to my questions quickly and was available all hours. Not only did he get my case resolved with a dismissal, he went above and beyond and got me an expungement without me even requesting it. He never beats around the bush and tells you like it is. At the same time is willing to work overtime to get the results you request. I would use David’s services again in the future.

Gabriel V.

An old felony charge came up, so I hired David and his team in June, and he got me a release on my own cognition on a felony charge in July which has never happened to me, and got it dismissed in October. He was responsive when I called and always kept me updated. Got my case dismissed, was easy to work and handled everything for me. He did an excellent job. I highly recommend David Chesley for any criminal defense.
