Without consent, or a warrant it is unconstitutional for the police to collect a DUI blood sample.
There are a few exceptions in which the police can obtain a blood test for investigation
In this article we will focus on the DUI medical blood draw exception, to a search warrant.
Under exigent circumstances, police can request a blood sample that is taken incidental to a blood draw for medical purposes.
The Arizona Supreme Court recently considered the question of when this exception would apply.
The blood draw exception requires medical personnel to give some of the blood sample drawn for medical reasons to a law enforcement officer, upon request.
The police can request a sample for a DUI investigation only if they have probable cause to believe the driver was under the influence of drugs or alcohol.
Here we take a closer look at the case and decision involving the medical treatment exception. , the AZ Supreme Court added another layer of protection to assure a driver’s rights are protected by due process of law.
In the past if police requested a DUI blood test under the medical treatment exception, they needed to show probable cause, exigent factors, and that a blood test was being done for medical reasons. As a result of this decision, that state further needs to provide a showing that the driver’s rights to direct their own medical treatment were not violated.
