Many states require motorists to stop at least ____ feet from the rail of the railroad and not more than ____ feet away.

Motorists are generally required to stop at least 15 feet from the railroad tracks. This distance is set to ensure the safety of both the driver and passengers, preventing potential accidents with oncoming trains. Stopping at this minimum distance provides adequate space to react and ensures that the driver has a clear view of any approaching trains. The upper limit of stopping no more than 50 feet away is also important; staying within this range ensures that the driver remains alert and focused on any signals or approaching trains without losing situational awareness.

The selected answer reflects a sensible standard for maintaining safety at railroad crossings, adhering to the principle of safety first when encountering the intersection of roads and railways.
