Plain-language summary

Beta

This bill would establish a specific measurable limit for THC, the active substance in marijuana, in a person's blood to legally define when someone is considered too impaired to drive. Currently, Kentucky law does not set a fixed THC blood level for driving under the influence, so this change would create a clearer legal standard similar to the blood alcohol limit for drunk driving. It would also update related laws to match the new standard. Who it may affect: drivers, law enforcement, and prosecutors handling impaired driving cases.
