Relating to crossing arms on buses that transport schoolchildren.

HB 1619 requires school buses manufactured in 2021 or later to have a front-mounted crossing arm that extends at least 70 inches outward when activated. This arm creates a safe zone for students crossing in front of the bus by requiring them to maintain distance from the vehicle. The bill also mandates specific mirror and flashing light systems for all school buses to improve visibility. School districts may accept donations to fund these required safety features, with the donation provision taking effect in 2025 and the full requirements in 2026. The bill directly affects school bus operators and students in Texas school transportation.
