Bill > SB230

This bill establishes a per se limit for marijuana blood concentration while driving in Kentucky, creating a new legal standard for determining marijuana impairment. Specifically, the bill adds language to define marijuana concentration as nanograms of tetrahydrocannabinol (THC) per milliliter of blood and introduces a new provision that makes it illegal to operate a motor vehicle with a marijuana concentration of 6 or more nanograms per milliliter of blood. The bill creates a two-tiered approach to marijuana impairment: if a driver has less than 4 nanograms of THC per milliliter of blood, they are presumed not to be under the influence, and if they have between 4 and 6 nanograms, the concentration can be considered as evidence of impairment along with other factors. The legislation amends multiple sections of Kentucky law to incorporate this new standard, including sections related to license suspension, hardship driving privileges, and ignition interlock requirements. These changes align marijuana testing standards with existing alcohol impairment laws, providing law enforcement with a clear, quantifiable metric for determining potential marijuana-related driving impairment, while also ensuring that drivers have mechanisms to challenge or mitigate potential penalties.
