Revises mileage limit for mandatory school transportation for students in preschool through grade four.

This bill revises New Jersey's school transportation policy by lowering the mandatory mileage threshold for preschool through fourth-grade students. Under the change, school districts must now provide free bus transportation to students living more than 1.5 miles from their public school (down from the previous 2-mile limit for this grade group). The bill maintains existing distance requirements for older students: 2 miles for grades 5-8 and 2.5 miles for grades 9-12. It directly affects public school students in preschool through fourth grade who live beyond the new 1.5-mile distance from their assigned school.
