2024(Espinoza, at p. 113.) The Espinoza court went on to state, however, “it is unclear whether the high court would approve of a civil license suspension based solely on a motorist’s refusal to submit to a warrantless blood test.” (Ibid.) Elaborating on this point, the Espinoza court noted that, under Birchfield and McNeely, “[t]he police could not force Espinoza to submit to a blood test against her will unless they obtained a warrant or showed there were exigent circumstances that justified a warrantless search.” (Espinoza, supra, 10 Cal.App.5th at p. 113 .) The Espinoza court stated: “Conseque

2024Rather than decide whether Espinoza’s license could be lawfully suspended based solely on her refusal to submit to a warrantless blood test, we conclude her license was lawfully suspended because she did not submit to a warrantless breath test.” (Espinoza, supra, 10 Cal.App.5th at p. 114 .) Here, of course, the facts differ from those in Espinoza.

2025Whether a warrantless blood test of a drunk-driving suspect is reasonable must be determined case by case based on the totality of the circumstances.’ ” (Alvarez, supra, 98 Cal.App.5th at p. 543, quoting McNeely, supra, 569 U.S. at p. 156 ; see also People v.

The Supreme Court then applied these legal conclusions to the three cases before it. ( Birchfield, supra, 579 U.S. at pp. 477–478.) The court held Birchfield could not be forced to submit to a warrantless blood test incident to his arrest.

2019As the First District stated in People v. Gutierrez (2018) 27 Cal.App.5th 1155 , review granted January 2, 2019, S252532 (Gutierrez), just because “the state cannot compel a warrantless blood test does not mean that it cannot offer one as an alternative to the breath test that it clearly can compel.” (Id. at p. 1161.)1 Hence, Birchfield does not prohibit a finding of implied consent under California’s former law under these circumstances.

Despite the absence of a per se rule, “[w]hen police have probable cause to believe a person has committed a drunk-driving offense and the driver’s unconsciousness or stupor requires him to be taken to the hospital or similar facility before police have a reasonable opportunity to administer a standard evidentiary breath test, they may almost always order a warrantless blood test to measure the driver’s BAC without offending the Fourth Amendment.” (Mitchell, supra, 588 U.S. at p. 8

2020(Missouri v. McNeely (2013) 569 U.S. 141, 152 [ 185 L.Ed.2d 696 ].) An exigent circumstance exists when blood-alcohol evidence is dissipating and “some other factor creates pressing health, safety, or law- enforcement needs that would take priority over a warrant application.” ( Mitchell, supra, 204 L.Ed.2d at pp. 1050-1051.) The United States Supreme Court found such factors 7 when a drunk-driving suspect was unconscious, and when the suspect was in a vehicle accident that required police to attend to other pressing needs.
