Requires school bus drivers to submit to biannual testing for drugs and alcohol.

This bill requires all school bus drivers in New Jersey - employed by public school districts or private/parochial schools - to undergo unannounced drug and alcohol testing twice each school year. It directly affects school bus drivers by mandating testing for alcohol, narcotics, and habit-producing drugs under state law, with immediate ineligibility for operation if results are positive or if a driver refuses testing. Drivers must be given an appeal process to challenge testing accuracy before termination, and school districts must submit testing evidence annually to county superintendents. The law aims to enhance student safety through regular, surprise screenings, building on existing background checks and medical requirements.
