Okla. Stat. tit. 63, § 63-4210.11: Refusal to submit to drug or alcohol testing -

Exceptions.

If a conscious person under arrest refuses to submit to testing

of his or her blood or breath for the purpose of determining the

alcohol concentration thereof, or to a test of his or her blood,

saliva or urine for the purpose of determining the presence or

concentration of any other intoxicating substance, or the combined

influence of alcohol and any other intoxicating substance, none

shall be given, unless the investigating officer has probable cause

to believe that the person under arrest, while intoxicated, has

operated a vessel in such a manner as to have caused the death or

serious physical injury of any other person or persons. In that

event, the test otherwise authorized by law may be made in the same

manner as if a search warrant had been issued for the test or tests.

The sample shall be taken in a medically acceptable manner at a

hospital or other suitable health care facility.
