When arrested for a DUI there are two common charges that a prosecutor files against a defendant.
- The first is driving under the Influence of alcohol under Vehicle Code 23152(a), and
- The second is driving with a BAC of .08 or more under vehicle code 23152(b).
In this post, I am going to show you 7 ways a BAC of .08& or more could be wrong.
But first, watch this video to understand what the prosecutor needs to prove for a conviction.
Under California Vehicle Code 23152(b) it is a crime to drive a motor vehicle with a BAC of .08 or more1
How Do Police Determine Your BAC is .08 or Higher?
Police officers will determine if your blood alcohol concentration was above .08 in one of two ways.
There is a rebuttable presumption that if the person had 0.08 percent or more, by weight of alcohol in his or her blood at the time of driving, that the person is guilty of DUI, whether or not the person was actually driving under the influence2.
However, the presumption is not conclusive and can be challenged on various grounds.
Lets start with the DUI breath test…….
There a number of ways that a breath test could have provided a false reading or your BAC was not .08 or higher at the actual time of driving rather than the time the test was taken.
- Your BAC was rising when you took the breath or blood test.
- You had mouth alcohol which gave a false reading.
- You were suffering from GERD or acid reflux when you took the test which gave a falsely high reading, or
- The breath testing machine was not properly calibrated.
- You were a passenger and not the driver of the vehicle.
Your BAC Was Still Rising
Let me give you an example of a situation where your BAC at the time of driving could have been lower than the legal limit.
After being pulled over for a DUI and taking some field sobriety tests a defendant blows a .08 BAC and is immediately arrested for DUI.
The defendant takes another DUI breath test at the police station which registers a .095 BAC.
In this scenerio you can clearly see that the defendants blood alcohol concentration was continuing to rise which would show that at the actual time of driving the defendant was even lower than the .08 original breath test.
This commonly happens because your body may have still been absorbing the alcohol as you drove.
Estimate Your BAC With Our Blood Alcohol Calculator
The Result was Inaccurate Due to Mouth Alcohol or GERD:
The result of the chemical test was based on mouth alcohol rather than deep lung air which would signify a true blood alcohol concentration.
A person with a condition such as GERD or acid reflux could potentially always have some amount of alcohol coming up from their stomach which may result in a falsely high reading.
To prove this an expert would have to be brought in for the defense and testify on behalf of the defendant.
The Breathalyzer Was Incorrectly Maintained
The chemical test machine has to be correctly calibrated and maintained.
If you can prove that the officers did not comply with the
- DUI breath testing requirements,
- That the machine was faulty, or
- That the technician was not competent, you may be able to get the test results thrown out.
You Were Not Driving The Car
To prove that you are guilty of violating vehicle code 23152(b), a prosecutor has to prove the following facts or elements3:
Was There Evidence of Your Driving?
To prove that you violated this offense, a prosecutor has to provide evidence that shows that you were actually “driving” with a BAC of 0.08% or higher.
This requires proving that you moved the car any distance no matter how slight6.
If the defendant was merely sleeping in the car while the car was parked, or if he/she was at the wheel while a friend ran into a store, he/she did not violate VC 23152(b).
For more on this topic see my article on the DUI “no driving” defense.
Now lets focus on a blood test…….
California’s Code of Regulations Title 17 governs the performance of blood and breath tests.
Title 17 requires that when a DUI blood test is conducted the following procedures have to be followed:
- The blood should be collected using sterile equipment
- The draw site must be sterilized using a non-alcoholic non-volatile cleaning agent
- The draw should be performed only by authorized personnel such as a specially trained technician
- There should be a sufficient amount of coagulant and preservative in the vile
- The blood should be mixed with the coagulant and preservative
- The blood should be stored properly in a clean dry contained that is closed with an inert stopper
How Do You Know If Title 17 Procedures Were Not Followed?
An investigation into the crime lab where the blood test was performed can be conducted.
Additionally, is you suspect the Blood test result is incorrect our firm can submit a DUI blood split order and have your blood independently tested from a different lab.
If any of these procedures are violated, the test results should be challenged as inaccurate, as the resulting BAC may be too high.
|Fine||$390-$1,000 + penalty assessments||$390-$1,000 + penalty assessments|
|Probation||3-5 years informal probation||3-5 years formal probation|
|License Suspension or Revocation||6 month – 3 years suspension7||4 year revocation|
|Ignition Interlock Device||Depends on county||Yes|
|Habitual Traffic Offender Status||No||Yes|
|DUI Program||3-30 Months DUI School||Yes|
|Jail Or Prison||Max of 6 months county jail||Max of 3 years state prison|
Additionally, there will be costs for SR-22 Insurance which will be required as a DUI offender.
Can you remove a violation of VC 23152(b) from your record?
After completing all requirements of sentencing you may be eligible to expunge a DUI conviction depending on the circumstances. However, expunging your conviction will not remove priorability for any future DUI’s.
Aggravating Factors: The following 4 factors, if present in addition to a violation of the offense Vehicle Code 23152(b), will cause a defendant to incur additional or enhanced terms of punishment.
These factors are called “aggravating factors.”
- BAC .15 or higher
- Refusal ff the chemical test
- Excessive Speeding or reckless driving
- Minor under 14 years of age in the vehicle
Pursuant to Vehicle Code Section 23578 — Excessive Blood Alcohol —
If a person is convicted of a violation of Section 23152 or vehicle code 23153 dui causing injury, the court will also consider a concentration of alcohol in the person’s blood of:
- 0.15 % or more, by weight, or
- the refusal of the person to take a chemical test,
As a special factor that may justify enhancing the penalties in sentencing, in determining whether to grant probation, and, if probation is granted, in determining additional or enhanced terms and conditions of probation.
- Penalty Enhancement
- Penalty Enhancement
Pursuant to Vehicle Code Section 235788, a defendant can incur additional or enhanced terms of punishment if you refused to submit to chemical testing.
What if I Could Not Understand the Officer?
If the officer asked you to take a chemical test and you did not respond than this may constitute a refusal9. However, the officer must admonish you in a manner that is clearly comprehensible to you10.
If you were so intoxicated that you could not understand the officer then you can still be held to answer for refusing a chemical test11.
Under Vehicle Code Section 23582, anyone who drives a car
- 30 or more miles per hour over the maximum, or posted speed limit on a freeway, or
- 20 or more miles per hour over the maximum, or posted speed limit on any other street or highway,
While also violating Sections 23152 or 23153 will, in addition to the punishment given upon conviction of a violation of Sections 23152 or 23153.
Be punished by an additional and consecutive term of 60 days in the county jail12.
Under Vehicle Code Section 23572, if you are convicted of Driving With a BAC of 0.08% or More under Vehicle Code Section 23152 and
- You have a minor riding with you in the car,
The court will impose additional penalties, based on which section of the Vehicle Code the original offense is punishable under13.
