Concerning impaired driving.

HB 2362 lowers Washington's legal blood alcohol concentration (BAC) limit for driving from 0.08% to 0.05% for all drivers, effective upon enactment. The bill amends statutes governing impaired driving (RCW 46.61.502 and 46.61.504) to establish this new threshold, alongside setting a THC concentration limit of 5.00 for cannabis impairment. It maintains existing penalties for violations but adds defenses for drivers who consumed alcohol/cannabis *after* driving but before testing. The change directly affects all drivers in Washington, aligning state law with international standards adopted by 84% of the global population.
