Which vehicles are typically exempt from stopping at railroad crossings?

Emergency vehicles are typically exempt from stopping at railroad crossings when they are responding to an emergency. This exemption is based on the understanding that emergency responders may need to reach their destination quickly to provide assistance or address urgent situations. However, it is important for emergency vehicle operators to ensure the crossing is clear and safe before proceeding, as trains have the right of way and can approach quickly.

School buses and public transport buses are generally required to stop at railroad crossings, regardless of the circumstances. This rule is in place to ensure the safety of passengers and to give the driver an opportunity to check for oncoming trains. The option stating that all vehicles must stop emphasizes the general requirement for all other vehicle types, highlighting the critical nature of safety around railroad crossings.
