SB 136 Wisconsin Senate · 2025-2026 Regular Session

Relating to: school bus back-up lamps.

SB 136 amends school bus lighting rules to allow painted school buses (per §347.44(1)) to use specific safety features. It permits one amber or white back-up lamp on each side (mounted near wheels, with downward light direction), front and rear illuminated signs (steady, non-glaring light), and LED strobe lights meeting SAE J845 Class II standards. These changes directly affect school bus manufacturers, school districts, and the Department of Transportation (which will set installation rules). The bill updates existing safety equipment requirements without creating new mandates, focusing solely on technical specifications for lighting and signage.
