Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 26 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“In cases where test results show levels of alcohol significantly above 0.10% and where blood samples have been obtained soon after suspects have been stopped, there is a very strong inference that blood alcohol levels were in the prohibited range while driving. However, ... where the blood alcohol test result barely exceeded the 0.10% level and the lapse of time between driving and the taking of the blood sample was not insignificant, the inference is weakened.”
2 later decisions quote this exact passage“The crime of driving under the influence can be committed not only by a person who drives, but also by one who “operates” or is “in actual physical control of the movement” of a vehicle. A person does not drive unless he actually has the vehicle in motion, however, a person may operate or be in actual physical control of the movement of a standing vehicle. These terms are more comprehensive than the term drive. (They cover certain situations where a person under the influence is a threat to public safety even though he is not driving at the time.) Thus a person operates a vehicle if he is in actual physical control of either the machinery of the motor vehicle or the movement of the vehicle itself.”
1 later decision quote this exact passage“[t]he entire width between property lines or other boundary lines of every way or place of which any part is open to the public for purposes of vehicular travel as a matter of right or custom.”
