Police officers must generally follow statutory and constitutional protections when arresting or interacting with individuals. In a recent case, the Washington Court of Appeals addressed the consequences of failing to provide the required statutory warnings before administering a breath test to a defendant arrested for driving under the influence (DUI).
In State v. Murray, 192 Wash. App. 1040 (2016), a Washington State Patrol Trooper stopped the defendant for a traffic violation. The trooper alleged that she smelled alcohol from inside the defendant’s vehicle and that the defendant’s eyes were bloodshot and watery and her speech slurred. After the defendant performed field sobriety tests, the trooper arrested her. During a standard inventory search, a pipe and a bag of marijuana were found in the defendant’s vehicle. At the police station, the trooper read the defendant the implied consent warnings for the breathalyzer test, but she failed to provide warnings about per se THC concentration in her blood. The defendant agreed to a breath test that indicated a level over the per se limit for alcohol.
Pursuant to RCW 46.20.308, an officer is required to inform a driver of specific warnings regarding the consequences of denying or submitting to a breath test. Before trial, the defendant moved to suppress the evidence of the breath test results, contending that the trooper’s failure to provide all of the warnings required by RCW 46.20.308 was a violation of her rights. The defendant’s motion was denied by the trial court, and the defendant was found guilty as charged. On appeal, the superior court reversed the lower court, holding that officers do not have discretion to decide which of the required warnings are given to subjects suspected to have consumed both alcohol and THC. The state appealed, and the matter was brought before the Washington Court of Appeals.
