Why should a driver be aware that some states allow certain small buses or vehicles under specific conditions to be exempt from the mandatory stop at particular crossings, while most large school buses are not?

Pick an answer

1. Exemptions apply universally to all school buses in every state
2. This distinction is irrelevant to how a driver should approach a crossing
3. Rules can vary based on vehicle type and specific crossing conditions, so understanding which rule actually applies to their bus matters
4. Every vehicle, regardless of type or state, follows the exact same railroad crossing rule with no variation, so a driver needs only one rule
