Which vehicles are required to stop at all uncontrolled railroad crossings?

School buses carrying children are required to stop at all uncontrolled railroad crossings due to the heightened safety concerns associated with transporting children. This regulation is in place to ensure that children are not at risk of accidents at potentially dangerous intersections where rail crossings do not have signals or gates.

The requirement for school buses to stop reflects the understanding that children may not be as aware of their surroundings as adults and need extra precautions to ensure their safety. In situations without visual warnings or signals, stopping allows the bus driver to look and listen for oncoming trains, making it safer for children to disembark or board the bus in proximity to these crossings.

While other vehicles have varying regulations regarding railroad crossings, school buses are uniquely mandated to prioritize the safety of their young passengers in these scenarios.
