The bill establishes a pilot program by the Washington State Patrol to evaluate the effectiveness of oral fluid roadside testing in enforcing driving under the influence (DUI) laws. The program will be implemented in at least ten geographical locations, with a deadline for initiation set for March 1, 2025. The State Patrol is tasked with selecting reliable oral fluid testing instruments, providing training for law enforcement officers who will administer the tests, and ensuring the protection of personally identifiable information.

Additionally, the bill mandates that the Washington State Patrol submit a report on the pilot program's outcomes to the relevant legislative committees by June 30, 2026. The provisions of this section will expire on January 1, 2027, indicating a temporary measure to assess the viability of oral fluid testing in DUI enforcement.
