When approaching a railroad crossing, what is the required minimum distance you must not pass within?

When approaching a railroad crossing, the required minimum distance to stop is 15 feet, which means it is important to keep a safe distance from the tracks. However, in relation to the question about not passing within a certain distance of the crossing, this typically refers to the stopping distance when you see warning signs or a signal indicating that a train is approaching. The correct answer of 100 feet reflects the standard measure used in many scenarios to ensure safety.

This distance allows enough space for safe observation and reaction, helping to prevent any potential accidents as trains can approach quickly and silently. Being 100 feet away provides the driver with sufficient visibility and reaction time to assess the situation and make informed driving decisions in relation to oncoming trains. Remember, safety around railroad crossings is paramount, as it is essential to be aware of your environment and adhere to the required distances to minimize the risk of collisions with trains.
