VISTA DUI DEFENSE LAWYER

If you have been arrested anywhere in San Diego County for driving under the influence of alcohol or drugs, including drunk driving car accidents or felony DUIs, Vista DUI attorney Peter M. Liss can help. He has personally defended hundreds of individuals following their DUI arrests in North County, and he guarantees all clients top-quality representation for a reasonable fee.

DUI Charges in Vista

When someone is arrested for driving drunk, and they have a Blood Alcohol Level above 0.08% (or 0.01% for minors and 0.04% for commercial drivers), they will be charged with a DUI. The charge can also be applied to anyone suspected to be driving under the influence of drugs, even legal medications.

What to do When You’re Pulled Over

Most people want to get back on the road as soon as possible after an officer stops them. However, if you were drinking, it is more important to protect your rights. Anything you say can be used as evidence against you, so if you are pulled over after drinking or using any drug (including legal medications that may impact your ability to drive), do the following:

Follow Directions

Follow the police officer’s instructions as much as possible, particularly when it comes to where and when to pull over your car, though you can wait to find a safe place to stop. If you fail to follow an officer’s instructions or pull over in a dangerous area, the prosecution will use it as evidence of impaired thinking. Do not exit your vehicle unless the police officer asks you to.

Remain Silent

Be polite to the officer, but never provide more information than is legally required. Roll down the window a few inches to speak with the officer and give him your driver’s license and insurance cards. You must provide information regarding your name, address, and nothing more.

Do not provide information about where you have been, where you are going, whether or not you have been drinking, and whether you have taken any medications. Instead, say you are invoking your Fifth Amendment right to silence.

Take a Chemical Test, Not a Field Sobriety Test (FST)

The officer may ask you to perform field sobriety tests or to submit to a preliminary alcohol screening device. Unless you are under 21, these tests are optional. Field sobriety tests are always optional, even for minors. Refuse to take them unless you know for a fact that you have no alcohol or drugs in your system. These tests are designed solely to provide the police with more evidence to use against you, and taking them can make your case much more challenging for your lawyer.

Submitting to a breathalyzer or blood test is not optional under California state laws. The Implied Consent law says you must choose one or the other. If you refuse, the police officers will get a search warrant for your blood, and you will face, at minimum, a one-year license suspension. Additionally, the prosecutors will charge you for refusing to take a chemical test, which carries mandatory jail time.

Write Everything Down

After you are released, write down every possible detail related to your DUI traffic stop. Try to remember everything the police officer said to you, every step of the chemical DUI test, and every other bit of information you recall. Even the smallest detail could make a dramatic difference in your case.

Many attorneys are able to successfully fight DUI charges by showing the officers lacked probable cause or by proving that the blood test or breathalyzer was not performed properly.

Call a Lawyer ASAP

You only have ten days to file for a license suspension hearing with the DMV, so call an attorney immediately. Don’t miss the opportunity to schedule your hearing. It allows you a chance to protect your license and provides you and your lawyer the opportunity to review and question the evidence against you. The experience serves as a sort of mini-trial that can make all the difference when it comes to preparing for the actual trial.

Don’t make the mistake of assuming these charges aren’t serious. A DUI will result in the loss of your license, expensive fines, and even jail time.

DUI Tests and Evidence

You cannot be charged with a DUI without evidence because the prosecution relies on this information to prove your guilt and secure a conviction. Without chemical tests and officer testimony, there is insufficient proof for you to be charged with a DUI, let alone convicted. When looking for the best Vista DUI lawyer for your case, be sure he understands the ins and outs of evidence law, as this will dramatically affect your defense.

Breathalyzer Vs. Blood Test

A professionally administered chemical analysis of a driver’s blood, breath, or, in very limited circumstances, urine, is the cornerstone of the prosecution’s case. Under California’s Implied Consent law, you must submit to a chemical test if asked to do one. If you refuse, police will obtain a search warrant to draw your blood, and you still will be charged with drunk driving. Violating the Implied Consent law will also cause you to lose your driver’s license for an entire year and face mandatory jail time.

Officers often ask suspects to take a breath test without informing them that they also have the option to take a blood test. However, you have the right to choose either chemical test. Drivers accused of driving under the influence of drugs generally must take a blood test, though urine tests may be available in rare circumstances. Your attorney may be able to challenge the evidence regardless of which chemical test you take.

Breathalyzers Are Less Accurate

Breath tests, performed with breathalyzer machines, are the best-known and most frequently used evidence in a DUI case. Despite their regular usage, these tests are not entirely accurate. Many things can throw off the results (though most myths about “beating the breathalyzer” are, indeed, only myths). These factors may fool the breathalyzer into thinking your Blood Alcohol Content (BAC) is higher than it actually is:

  • Chemicals in the testing area
  • The breathing pattern of the test-taker
  • Medical conditions such as diabetes
  • Diet sodas
  • The test-taker’s temperature
  • Hand sanitizer
  • Improper calibration
  • Acid reflux
  • Inexperienced operators
  • Being a smoker
  • Low-carb or Keto diets
  • Temperature fluctuations in the testing area
  • Recent belching or regurgitating

Blood Tests Can be Retested

Fewer things can cause a blood test to go wrong than a breath test, leaving a lawyer with fewer ways to challenge the results. However, a blood draw requires a sample to be stored, meaning it can be retested later. A number of procedures must be strictly adhered to for a blood result to be legally admissible, including proper collection, storage, transportation, and testing methods. Problems that could affect its admissibility include:

  • the wrong type of tube being used
  • the sample being stored improperly
  • the test being performed improperly
  • the sample being tampered with
  • alcohol being used to clean the skin
  • the sample getting lost at any point

Field Sobriety Tests as DUI Evidence in Vista

While shows often depict police officers asking DUI suspects to do things like recite the alphabet backward, the National Highway Traffic Safety Administration (NHTSA) has approved only three field sobriety tests (FST) for use as courtroom evidence —though some officers still request suspects to take other tests. Together, these tests are estimated to be 82-91% accurate in ideal conditions. However, the accuracy of these highly subjective tests drops dramatically under real-world conditions. While the tests are optional, police officers rarely inform suspects that they have the right to abstain. Luckily, an experienced DUI lawyer can help fight this type of evidence.

Test NameThe Walk and Turn Test (WAT)The One-Leg Stand (OLS)The Horizontal Gaze Nystagmus (HGN)
Accuracy Level68-79%65-79%77-89%
InstructionsWalk heel to toe in a straight line, then turn and walk backStand on one leg while counting out loudFollow a pen or flashlight with your eyes without moving your head
PurposeEvaluating the suspect’s balance and ability to follow and remember directionsMeasuring a person’s ability to balance while focusing on a simple activityDetermine if the person’s eyes move smoothly or erratically
ProblemsUneven pavement, physical disabilities, memory conditions, and poor footwear can affect balancePoor footwear and mental or physical impairments can negatively impact performanceEyesight problems make this test more difficult —and 95% of officers administer the test improperly

Officer Testimony

The police officer’s testimony is one of the most critical pieces of evidence in a DUI trial. It can make or break your case because the officer is considered an “expert witness.” The officer will explain:

  • why they pulled you over
  • what made them believe you were drunk
  • your behavior during the interaction
  • what you said during the encounter

It is rare for officers to fail to submit the required paperwork after a drunk driving arrest or to fail to appear at a trial. For these reasons, your DUI defense lawyer’s ability to critically question the officer’s testimony is essential to winning your case, as it can help undermine the officer’s credibility.

The Best DUI Defenses Used in Vista

If you have been accused of driving under the influence of alcohol or drugs, you probably have many questions, but the most pressing question is likely, “Is it possible to beat my DUI charges?” While no attorney should ever guarantee the outcome of a case, you’ll be happy to know that plenty of people can and do successfully fight their drunk driving charges in San Diego County. However, DUI case law is very complex, and many defenses apply only to a handful of scenarios. Avoiding a conviction is typically only possible with the help of a skilled Vista attorney with a thorough knowledge of the best possible DUI defenses.

Challenging Chemical Test Results

One of the main pieces of the state’s evidence in a DUI trial is the chemical test. If you can prove it was improperly performed or that the results were otherwise falsely high, you may weaken the state’s case enough for you to win your case.

While chemical tests are rarely exempted as evidence, if your case goes to trial, your lawyer in Vista may be able to question these factors enough to win the jury over, which is why challenging this evidence is one of the most successful DUI strategies.

The Initial Traffic Stop Was Illegal

California DUI laws state that police must have a reasonable suspicion that you committed a Vehicle Code violation or are driving impaired before stopping a vehicle. They must also not detain a driver longer than is reasonable if they don’t suspect a crime.

If an officer stopped you for an infraction unrelated to your driving and had no cause for reasonable suspicion, he would have no grounds to ask you to take a field sobriety test or breathalyzer. An officer lacking reasonable suspicion is one of the most common reasons for DUI charges to be dismissed in Vista. Other mistakes officers could make that may undermine the prosecution’s case include:

  • Taking a blood sample without a warrant
  • Improperly performing a field sobriety test
  • Not warning suspects about the consequences of refusing a chemical test
  • Failing to observe suspects for 15 minutes before a breathalyzer to ensure they do not belch or regurgitate, which can falsely inflate the test results
  • Administering the breath test incorrectly
  • Failing to maintain the blood sample’s chain of custody

The Black and White Fever Defense

A common defense used to question the officer’s observations regarding a defendant’s erratic driving behavior is known as “black-and-white” fever. This condition occurs when someone notices that a police vehicle is following them, and they start looking in their rearview mirror more and more often until it affects their concentration and ability to drive. Worrying about getting pulled over can distract drivers so much that they may start driving erratically. Many jurors will relate to this feeling.

The Rising Alcohol Defense

Practically everyone would eventually be over the legal limit to drive after taking 5 shots of vodka at once. But it takes anywhere from 20 to 90 minutes for the alcohol to take effect, meaning if someone drove before that time, they were not yet drunk.

The rising alcohol defense argues that you did drink alcohol, but it did not enter your system when you were driving but did by the time your BAC was tested. Since you are only guilty of DUI if you are under the influence while behind the wheel, you did not break the law if the alcohol was not yet affecting you.

This defense will not work if you took a breathalyzer shortly after being pulled over, unless it showed you were under the legal limit and you failed a second test later.  For people well over the limit, this defense can sometimes be used to argue that they should be sentenced to basic DUI penalties, rather than facing enhanced penalties for having a high blood alcohol level.

The DUI Checkpoint Was Operated Illegally

DUI checkpoint

While DUI checkpoints are legal, they are only permitted if performed under a specific set of rules. Some courts insist that police must allow drivers the opportunity to turn away and leave the checkpoint rather than pass through it, although some do not require a way to opt out. If officers do not stop every car, then the vehicles must be stopped at set intervals —meaning they cannot stop a specific car based on how it, or its driver, looks. Even if a driver has slurred speech, they cannot be stopped if they do not fit into the pre-determined pattern.

If your rights were violated at an improperly operated checkpoint, a Vista DUI attorney could help get the charges against you dismissed or reduced.

The Medical Emergency Defense

Those seeking help in a true, immediate emergency have a solid defense against DUI allegations as long as they had no alternative. While only applicable in a handful of cases, it is a total defense, meaning that when successfully argued, you cannot be convicted for a DUI charge no matter your BAC.

To use this defense, your attorneys must show that a reasonable person would have acted the same way. For example, if the adults on a family camping trip are drinking, they could drive to get aid for a child who stopped breathing if they are out of cell phone range.

Other emergencies also qualify, but only if a person believes the life or that of another person is at risk. For example, you could legally drive to flee from someone threatening you with a gun, as long as you stopped driving once you escaped.

Involuntary Intoxication

If you drove after someone spiked your drink with drugs or alcohol without your knowledge and you started to feel weird or woozy, you did not break the law. However, it is illegal to drive knowing you are intoxicated, so if you realized you were drunk or high, it would be a crime.

Involuntary intoxication is the reason those who suffer from auto-brewery syndrome can successfully fight their DUI charges.

DUI Plea Bargains in Vista

Even in cases where you may not be able to fight your charges entirely, a skilled DUI attorney may be able to negotiate a beneficial plea bargain with minimal sentencing or alternative sentencing. Attorneys can often have the charges reduced to a wet reckless rather than drunk driving.

DUI Sentences in Vista

Those found guilty of driving under the influence in San Diego County face jail time, $390 to $1000 in fines (plus a 180% penalty assessment), alcohol or drug treatment programs, vehicle impoundment between 6 and 12 months, driver’s license suspensions, and mandatory use of ignition interlock devices. The specific penalties vary based on whether or not you have any previous DUIs on your record or if you may face enhanced penalties, such as having a minor in the vehicle, excessive speeding, or a BAC over 0.15%. No matter the penalties, even celebrities can expect a DUI conviction to change their lives and cost a lot of money, both in terms of court fines and higher insurance costs.

When is a DUI a Felony?

A 4th or subsequent DUI within 10 years can be filed as a felony. When an intoxicated driver causes a car accident by driving negligently or violating a traffic law, it can also be a felony if someone is even slightly injured. The sentences are even more severe when someone dies in an accident. Felony-level DUI charges always require the expertise of a skilled defense attorney.

Military DUI Penalties

Anyone charged with drunk driving on a military base, as well as members of the armed service who are charged with DUI off the base, will be charged in a federal court. JAG officers prosecute these cases, and while the penal codes are the same as under California law, the sentences are typically lighter.

Alternative Sentences Available in San Diego County DUI Cases

Alternative sentences are usually only available as part of a plea bargain, where you agree to plead guilty to one or more criminal charges. Whether or not you can receive an alternative sentence depends on your particular case, the charges you plead to, the agreement itself, and whether the judge accepts that agreement. Alternative sentences can include alcohol or drug rehabilitation programs, community service, counseling and/or attending AA meetings, MADD VIP programs, probation, electronic monitoring under house arrest, and other sentences.

DUI FAQs

Why are There Multiple DUI Charges?

In California, those accused of driving under the influence of alcohol are usually charged with two different offenses, “driving under the influence of alcohol” and “driving with a blood alcohol level of .08 or higher.” Both offenses carry the same penalties. You cannot be sentenced for both crimes, but you may be found guilty of one, both, or neither of the charges.

Those accused of driving under the influence of drugs are only charged with this specific charge. If drugs and alcohol are present, the charge will be “driving under the influence of alcohol and drugs.”

Can You Get a DUI if Your BAC was Under 0.08%?

Driving under the influence is a crime even if your blood alcohol content is below the legal limit as long as the alcohol affects your ability to drive. If you are a non-commercial driver over the age of 21 and are arrested with a BAC of .05% or below, you are presumed innocent of drunk driving. However, if your BAC is below 0.08% but above 0.06%, the case will mainly rely on the police officer’s testimony, including how you fared on any Field Sobriety Tests you took.

Additionally, drivers under 21 are subject to California’s zero-tolerance DUI law, meaning they can get a DUI for driving with a BAC over 0.01%. Commercial license holders cannot drive with a BAC over 0.04% at any time, while drivers for hire (for companies such as Lyft) cannot have a BAC above 0.04% while on the clock.

What Should I do if I am Pulled Over and the Officer Asks if I was Drinking?

If you have not been drinking, tell the truth. If you have been drinking, refuse to answer and say you are invoking your 5th Amendment rights. You are not required to answer any questions that may incriminate you. These same rules apply when an officer asks where you are coming from, especially if you just left a bar or a party.

What is the Legal Limit for Driving on Drugs?

There is no legal limit defining how much marijuana, methamphetamine, heroin, cocaine, or other drugs someone may consume while behind the wheel. You even can be charged with driving under the influence when taking prescription drugs if they affect your ability to control a vehicle. Just explaining to the police that you used a prescription medication can be used as evidence against you.

What is a Wet Reckless Charge?

A “wet reckless” is a reduced offense from DUI that can be used as a prior if you are charged with a DUI in the future and will result in two points being added to your DMV record. It has lower fines and a shorter probation period than a true DUI. The court and DMV record will show a conviction for reckless driving (with alcohol conditions). The DMV will not take any further action to suspend your license for the conviction, but you still face a 4 month suspension for having a BAC of .08 or above.
