The proposed legislation, known as the Richard Lenhart Act, aims to enhance the safety and security of students on public school buses by designating trespassing on these buses as a felony offense. The bill introduces a new section to chapter 9A.52 RCW, defining "school bus trespass" as knowingly entering or remaining unlawfully on a public school bus or intentionally disrupting its normal operation. This offense is classified as a class C felony. The act outlines exceptions for law enforcement officers, authorized personnel, and emergency situations, while also granting local law enforcement the authority to enforce these provisions.

Additionally, the bill mandates that school districts and educational institutions collaborate with local law enforcement to establish enforcement protocols and implement educational programs to raise awareness about the importance of safety on school buses. It also requires the placement of visible warning placards on school buses regarding the consequences of trespassing. The existing law, RCW 9.94A.515, is reenacted and amended to include "School Bus Trespass" as a recognized crime within the seriousness level table. The act includes a provision ensuring that if any part of the legislation is deemed invalid, the remainder will still be enforceable.
