This Idaho bill (H 500) updates traffic laws to explicitly include human-powered vehicles, bicycles, and electric-assisted bicycles under existing motor vehicle regulations. It requires drivers to exercise due care to avoid collisions with these vehicles and gives riders the same rights and duties as motor vehicle drivers (except where impractical). Key provisions ban riding without a permanent seat, limit passenger capacity to the vehicle's design, and allow secure child carriers. The changes apply to all riders of these vehicles and take effect July 1, 2026.
