You must always stop within __________ with a lowered crossing gate, a flashing electric signal or a rapidly-approaching train.

When approaching a railway crossing with a lowered gate, a flashing electric signal, or a rapidly-approaching train, it is crucial to stop at an appropriate distance to ensure safety. Stopping between 10 to 50 feet from the outer rail allows enough space to avoid any potential hazards associated with trains, which can move at high speeds and may not be visible until they are very close. This distance is set to provide a safe buffer zone for both the vehicle and the train, ensuring that drivers do not endanger themselves or anyone else nearby.

Following this guideline helps prevent accidents and reinforces the importance of respecting railway signals. Understanding this rule is essential for maintaining safety while driving near rail crossings, so that drivers can react swiftly and correctly when encountering these warning signals.
