NC S16

Expands "implied-consent offenses" to include violations of G.S. 20-141.4(a2) in addition to impaired driving and alcohol-related offenses.

Requires law enforcement to request a blood sample from persons charged with G.S. 20-141.4 violations, in addition to or instead of breath analysis, unless breath sample shows .08 alcohol concentration or higher.

Mandates law enforcement officers to seek a warrant for blood sample if a person charged with G.S. 20-141.4 refuses to provide one and officer has probable cause to believe offense involved impaired driving or was alcohol-related.

Provides that failure to obtain a blood sample under warrant procedures is not grounds for charge dismissal and is not an appealable issue.

Effective December 1, 2011, and applies to offenses committed on or after that date.
