Many people are surprised to learn that refusing a breath test does not always prevent law enforcement from obtaining chemical evidence.

In some situations, officers may request a search warrant authorizing a blood draw to obtainevidence in a DWI investigation.

Attorney Jordan G. Fries helps clients understand how blood warrants work, the legal requirements involved, and how those issues may affect the defense of a DWI case.

What Is a Blood Warrant?

A blood warrant is a search warrant signed by a judge or magistrate authorizing law enforcement to obtain a blood sample for chemical testing.

Before issuing a warrant, the court generally reviews information presented by law enforcement to determine whether legal requirements have been met.

Blood warrants are frequently requested after:

  • Breath test refusals
  • Serious accidents
  • Injury crashes
  • Fatal crashes
  • Situations where officers believe additional evidence is necessary

Does a Blood Warrant Mean the Case Is Over?

No.

A blood test is only one piece of evidence.

Questions may still arise regarding:

  • The traffic stop
  • The warrant application
  • Probable cause
  • Collection procedures
  • Laboratory testing
  • Chain of custody
  • Constitutional issues

Each step deserves careful review before conclusions are drawn about the strength of the State’scase.
