How far should you stop from a train crossing when lights are flashing?

When you encounter a train crossing with flashing lights, it is crucial to stop a minimum distance to ensure your safety and that of others on the road. Stopping at least 15 feet from the crossing provides ample space to avoid potential dangers associated with approaching trains. This distance is designed to allow enough reaction time and to prevent your vehicle from being in harm's way should a train be approaching, which may not always be immediately visible. Additionally, this distance helps ensure that your vehicle does not interfere with any railway equipment or the movement of trains.

In comparison, the lesser distances suggested in other choices may not provide sufficient safety buffer, especially since trains can approach quickly and can take a significant distance to come to a complete stop. Observing the proper stopping distance is vital for driver awareness and promoting safe practices around rail crossings.
