In addition, any state, county, or municipal law enforcement officer who is certified pursuant to chapter 590 may, prior to arrest, administer a portable chemical test to any person suspected of operating any vessel in violation of section 306.111 or 306.112. A portable chemical test shall be admissible as evidence of probable cause to arrest and as exculpatory evidence, but shall not be admissible as evidence of blood alcohol content.

4. A licensed physician, registered nurse, or trained medical technician, acting at the request and direction of a law enforcement officer, shall withdraw blood for the purpose of determining the alcohol content of the blood, unless the medical personnel, in the exercise of good faith medical judgment, believes such procedure would endanger the life or health of the person in custody. Blood may be withdrawn only by such medical personnel, but such restriction shall not apply to the taking of a breath test or a urine or saliva specimen. In withdrawing blood for the purpose of determining the alcohol content in the blood, only a previously unused and sterile needle and sterile vessel shall be used and the withdrawal shall otherwise be in strict accord with accepted medical practices. Upon the request of the person who is tested, full information concerning the test taken at the direction of the law enforcement officer shall be made available to such person.

6. Any person who is dead, unconscious or who is otherwise in a condition rendering such person incapable of refusing to take a test as provided in sections 306.111 to 306.119 shall be deemed not to have withdrawn the consent provided by section 306.116 and the test or tests may be administered.
