Driving Under the Influence Jury Instruction
Vehicle Code section 23152(a) as defined by CALCRIM 2110
The defendant is charged Count 1 with driving under the influence of an alcoholic beverage or a drug or under the combined influence of an alcoholic beverage and a drug in violation of Vehicle Code section 23152(a).
To prove that the defendant is guilty of this crime, the People must prove that:
1. The defendant drove a vehicle;
AND
2. When he or she drove, the defendant was under the influence of an alcoholic beverage or a drug or under the combined influence of an alcoholic beverage and a drug.
A person is under the influence if, as a result of drinking or consuming an alcoholic beverage and/or taking a drug, his or her mental or physical abilities are so impaired that he or she is no longer able to drive a vehicle with the caution of a sober person, using ordinary care, under similar circumstances.
The manner in which a person drives is not enough by itself to establish whether the person is or is not under the influence of an alcoholic beverage or a drug or under the combined influence of an alcoholic beverage and a drug. However, it is a factor to be considered, in light of all the surrounding circumstances, in deciding whether the person was under the influence.
An alcoholic beverage is a liquid or solid material intended to be consumed that contains ethanol. Ethanol is also known as ethyl alcohol, drinking alcohol, or alcohol. An alcoholic beverage includes __________ <insert type[s] of beverage[s] from Veh. Code, § 109 or Bus. & Prof. Code, § 23004, e.g., wine, beer>.]]
A drug is a substance or combination of substances, other than alcohol, that could so affect the nervous system, brain, or muscles of a person that it would appreciably impair his or her ability to drive as an ordinarily cautious person, in full possession of his or her faculties and using reasonable care, would drive under similar circumstances.
If the People have proved beyond a reasonable doubt that the defendant's blood alcohol level was 0.08 percent or more at the time of the chemical analysis, you may, but are not required to, conclude that the defendant was under the influence of an alcoholic beverage at the time of the alleged offense.
In evaluating any test results in this case, you may consider whether or not the person administering the test or the agency maintaining the testing device followed the regulations of the California Department of Health Services.
It is not a defense that the defendant was legally entitled to use the drug.
If the defendant was under the influence of an alcoholic beverage and/or a drug, then it is not a defense that something else also impaired his or her ability to drive.
