During a Los Angeles DMV hearing, the burden is on the driver to prove that they were not intoxicated while driving at the time of the arrest. If an attorney has been hired on the case, then it is the job of the attorney to present a case that demonstrates that there was little or no blood alcohol content. This is completed through testimony, casting doubt on the credibility of the arresting officer’s report and any additional witnesses or documents that are necessary.

During the routine DMV hearing the DMV officer will determine whether there was reasonable suspcicion of the arresting officer to stop the driver, whether a blood alcohol content test was taken, and whether the results of that test were over .08. For most DMV hearings, the issues addressed will be these. However, when no BAC test was taken, the DMV hearing will follow an alternate path.

When there is a refusal, the officer will address the issues pertaining to the refusal. They will ask what the reasons were for refusing to take any of the tests offered and whether the person was read an admonishment of rights regarding the refusal.

Contrary to what some people may think, a DUI case against a person is not dismissed based simply on the fact that there is no blood alcohol content (BAC) reading. Many people think that if they refuse to take a BAC test, then there is no evidence or proof against them that they were intoxicated while driving. Not only is this not the case, but it may lead to additional penalties if the person is found guilty.

When granted driving privileges in California, a person agrees to comply with authorities if stopped or questioned for a DUI. This implied consent is a silent acceptance when a person is issued a California driver’s license. When a person refuses to take a BAC test it is a violation of the implied consent and is taken into serious consideration by legislation and the Courts.

This BAC test refusal does not lead to a dismissal of a case due to lack of evidence. There are other types of evidence that will be introduced in court by Prosecution that could lead to a conviction. The officer’s report is considered evidence. It contains the arresting officer’s observations and account of the night of the arrest. This is referred to as discovery. Observations made by the officer are held with high credibility and will be taken into consideration by the Judge as strong evidence of the driver’s intoxication.

During a routine DUI stop in Southern California, the officers will ask the driver to submit themselves for a field sobriety test. This is usually a breathalyzer test administered at the site of the stop and gives officers a preliminary idea regarding the person’s blood alcohol content (BAC). This BAC test is not mandatory, and if completed, is completed as a courtesy and in an effort to cooperate with officers.

If a driver is taken into a police station on suspicion of the DUI, they will be offered a second BAC test, either blood or breath. The second test administered at the station is mandatory and refusal to do so can result in added penalties and consequences. When a driver is issued a California driver’s license they agree to comply and cooperate with officers during any DUI stop. This includes submitting to a blood or breath test so that officers may collect an accurate reading for the person’s blood alcohol content. This implied consent is an agreement between anyone with a valid driver’s license and the State of California and if violated warrants significant consideration.

When a driver refuses to take a BAC test at the station, it is considered an enhancement to the DUI charge. An enhancement results in penalties in addition to those of a DUI without refusal. This includes a longer suspension of driving privileges, additional fines and mandatory jail time.

If a person is charged with a DUI, and they refused to take a breath or blood test at the time of the arrest, they may face additional consequences if convicted. When a driver is issued a California license, they give implied consent to submit for a blood alcohol test if asked to do so by officers. When a person refuses to do so, they are violating this previously given consent, and the penalties are taken seriously by the DMV and the government.

Many of our clients do not explicitly refuse to take a blood or breath test, but are unable to do so for various reasons. For example, many people who are overwhelmed and stressed out find it difficult to calmly breathe into a breathalyzer to get an accurate result. Some have asthma and are unable to properly breathe into the machine. Those that are unable to take the breath test and provide usable results, must take the blood test as an alternative. But many times, the officials administering the blood test are unable to find a vein or collect a sample large enough. The driver may also have a fear of needles and cannot submit to the blood these. As a result, the person is unable to take the blood test or the breath test, but have cooperated and provided legitimate attempts to do so.

For example, say Sally is stopped for a DUI and is asked to take a BAC test. She has asthma and does not have her inhaler with her. She, nevertheless, tries to breathe into the machine in order to provide a sample but officers tell her that none of the attempts were valid. She is then asked to take a blood test since the breath test was not valid. They try to take her blood but cannot find a vein and after several attempts, fail at gathering a sample. Sally followed directions and tried to aid the officers in gathering a sample to the best of her ability, but because of uncontrollable factors she was unable to do so.

When a person is stopped and asked to take a Blood Alcohol Test, a refusal to do so, may lead to serious consequences. When a person is granted the privileges of driving in California, along with the obligations and duties is implied consent to cooperate if a driver is questioned by officers regarding a possible DUI. By holding a valid driver’s license, you are agreeing that if you are stopped by officers, you will comply with requests to take a breathalyzer or blood test in order to test your blood alcohol content (BAC). Refusing to take the BAC test will have serious consequences because you are going against your previously given consent.

During a DUI arrest, officers will administer BAC tests at two separate occasions. You will be given a field sobriety test at the scene of the stop when the officer initially questions the driver. The initial sobriety test is not required by law and will not have severe consequences for refusal. However, the breath or blood test you are asked to take after being taken into custody at the police station is required by law. You do have the right to refuse, but will face additional consequences if convicted of a DUI.

If you refuse to take the breath or blood test that is required, officers must admonish you of the consequences. They must read it verbatim from a form and have you sign it acknowledging that you understand the additional penalties you may face for having refused. If this form is not read and signed, there is a strong argument for any additional penalties incurred as a result of the refusal to be dismissed.

California state law prohibits anyone from driving a motor vehicle when your driving ability is impaired under section 23152 (a) of the vehicle code. Drivers are also prohibited under section 23152 (b) of the vehicle code to drive a motor vehicle when their blood alcohol level is a .08% or more.

Whether you take a breath test or blood test after being stopped and arrested on suspicion of driving under the influence, the seriousness of your case relies in great part on the readings obtained at the time that you were stopped and tested.

A criminal prosecution for this charge carries serious consequences including probation, fines in excess of $1500, required attendance at a lenghly alcohol program, and a range of other consequences.

Many different factors come together to affect the rate of alcohol absorption, how quickly it is distributed into your blood stream and how quickly it is eliminated from your body.

Alcohol absorption is affected by the food you have ingested and the type of drink. When food is eaten along with alcohol, the alcohol absorption is a lot slower and the blood alcohol concentration peak (the point of greatest intoxication) is generally achieved anywhere between an hour to six. For people who haven’t had as much to eat, and are not eating along with their alcohol, the blood alcohol concentration peak is reached faster, generally in half an hour to two. The type of food ingested; fat, proteins or carbohydrates may have an effect on the quickness of absorption, but there is no concrete evidence. There is proof however, that the bigger the meal, and the closer in time to drinking that it is eaten, there is a slowing effect on alcohol absorption.

The stronger a drink is, the faster it will be absorbed by the body. Drinks that are generally between 10% and 30% of alcohol concentration will be most rapidly absorbed. Drinks that are less than 10% will take longer to be absorbed by the body.

Client always asked me at our first consultation, whether or not it is possible to get the their recent DUI case dismissed. I provide each client with an honest answer, that is, it depends. The law requires that for a driver to be convicted of a driving under the influence charge, certain legal requirements must be properly proven.

Regardless of a drivers blood alcohol level at the time that they were stopped on suspicion of driving under the influence, the police must legally justify a traffic stop by specifically identifying the vehicle code violation committed by the driver which gives rise to a lawful stop. This critical foundation is known as the principle of probable cause. Essentially, every DUI stop is required to have sufficient probable cause, or legal reason.

The absence of probable cause requires dismissals are granted, when it is determined by a prosecutor, judge, or jury that the officer lacked probable cause to justify a stop. Our firm recently represented a client who was stopped by the police for driving without his rear license plate illuminated. The driver was arrested for DUI because he had a blood alcohol reading of .18, over two times the legal limit. This case was ultimately dismissed on a defense motion when the driver and two passengers contested the police allegation regarding the light.sThe judge determined that the officer lacked probable cause to stop the driver because he believed that there was in fact a working license plate light as testified by the driver and his witness/passengers.

This is a very good question. There are two kinds of chemical tests under California state law to determine a driver’s blood alcohol content (BAC) at the time he was stopped on suspicion of driving under the influence of alcohol, drugs, or both. Until recently, there was also a urine test which was part of the drivers choice of tests. This test after many years. was eliminated by the legislature due to their determination that this type of test did not meet the high standards of accuracy required by the law.

There are two remaining tests which a suspected drunk driver has to chose from. These tests are the blood and breath tests. The blood test, which most experts view as the more accurate of the two because this test essentially through a direct analysis, measures the percentage of alcohol in the blood drawn from a suspected driver.The result is a blood alcohol concentration or bac which is directly correlated to the language of the law prohibiting blood-alcohol levels of .08 or over.

In addition, if the suspected driver is also under the influence of a drug, a blood test or urine test is the only way to determine their presence. A breath test is only capable of measuring alcohol.

There is nothing illegal about drinking alcohol. There or is also nothing illegal about drinking alcohol and driving. It is only against the law to drive a motor vehicle with a blood alcohol level (BAC) of .08% or more.

The state of California created this law under section 23152 of the vehicle code. This law has a number of different sections which make it illegal to drive a motor vehicle under certain circumstances. 23152 (a) V.C. prohibits any person to drive a car when their driving ability is impaired by either alcohol or drugs or the combination. 23152 (b) V.C. prohibits driving by those people who have a blood-alcohol level of .08% or more.

When I asked my clients how much they have had to drink, the most common response is with a number. For example, clients will tell me they had a couple of drinks, a few glasses of champagne etc. Our average client speaks of their drinks like they were all the same. Nothing could be further from the truth. This oversimplification, is what commonly gets my clients in trouble. Although, counting and keeping track of what one has to drink is important, what you are drinking is just, and maybe more important than just the number.
