What is the minimum stopping distance required at a railroad crossing?

The correct answer specifies that the minimum stopping distance required at a railroad crossing is no closer than 15 feet and not further than 50 feet. This standard is established to ensure safety when approaching a railroad crossing. Stopping no closer than 15 feet allows for a safe buffer zone from the tracks, helping to prevent collisions with any trains that may be approaching. Additionally, the upper limit of 50 feet ensures that drivers can still have a clear view of oncoming trains while maintaining their position at a safe distance from the crossing itself. This distance is particularly crucial for school bus drivers, as they are responsible for the safety of their passengers, making it imperative to adhere to these guidelines when approaching railroad crossings to prevent accidents.

Other options suggest differing distances that either fall beneath the minimum requirement or exceed the practical distance needed to maintain safety without sacrificing visibility. As such, adhering to the specified range is vital for safety compliance at railroad crossings.
