Concerning impaired driving.

SB 5742 amends Washington State’s impaired driving laws by lowering the blood alcohol concentration (BAC) threshold for certain penalties from 0.15% to 0.10% for first-time offenders within seven years. It requires courts to impose electronic home monitoring with alcohol detection breathalyzers (or 24/7 sobriety programs) instead of jail time for some offenses, with offenders paying associated costs. The bill also mandates non-suspendable minimum fines ($350-$500) and adds substance use assessments for repeat offenders. It directly affects drivers convicted of driving under the influence with specific BAC levels or test refusals. The changes apply to all impaired driving convictions under RCW 46.61.502 or 46.61.504.
