This bill mandates that all school bus drivers, including those employed by boards of education and private or parochial schools, undergo biannual unannounced medical testing for drugs and alcohol. The testing will check for the presence of substances as defined by the "New Jersey Controlled Dangerous Substances Act." The timing of these tests will be determined by the employing board or contractor, who will also receive the results. If a driver fails the test or refuses to take it, they will be immediately disqualified from operating a school bus. Additionally, the Commissioner of Education is tasked with establishing criteria for disqualification and creating an appeal process for drivers who wish to contest their disqualification based on testing results.

Furthermore, the bill amends existing laws to require that evidence of the medical testing be filed with the county superintendent before any driver is assigned to operate a school bus. This includes the submission of the driver's name, social security number, valid school bus driver's license, criminal background check, and records of any alcohol or drug-related motor vehicle violations. The new provisions aim to enhance the safety of school transportation by ensuring that drivers are regularly tested for substance use.
