MO SB1014

Chemical analysis of blood, breath, saliva, or urine showing 0.08% or more blood alcohol content constitutes prima facie evidence of intoxication in criminal trials, license suspension proceedings, and municipal ordinance violations involving vehicles, vessels, or aircraft

Charges must be dismissed with prejudice if chemical analysis shows less than 0.08% blood alcohol, unless: the test is unreliable due to time lapse, the defendant was under the influence of controlled substances, or there is substantial evidence of intoxication from witness observations or defendant admissions

Breath test results from offenses occurring between December 30, 2012 and April 4, 2014 are made admissible if simulator solutions used to calibrate breathalyzers had vapor concentrations within 5% of 0.10%, 0.08%, or 0.04%

Explicitly overturns Missouri court rulings in Stiers v. Director of Revenue (2015 and 2016) that had restricted admissibility of certain breath test evidence

Declared an emergency act, taking effect immediately upon passage to address public safety concerns related to intoxicated driving prosecutions
