Define 'Restricted Speed'.

• A. A speed that permits stopping within one-half the range of vision. It also permits stopping short of a train, car, on-track equipment, obstructions, stop signals, derails, or improperly lined switches. It is not to exceed 15 mph until the entire movement has cleared turnouts, crossovers, and power operated switches.
• B. A speed that permits stopping at any distance.
• C. A speed limit for yard operations only.
• D. A speed that allows stopping at any distance.

Answer: (D)

Restricted speed means you operate at a pace where you can stop within the distance you can see ahead, and you must be prepared to stop for any obstruction, signal, or hazard that could appear on the track. This is used in conditions where vision is limited or where track conditions and signals require extra caution. In practice, you’re limited to a low speed (often around 15 mph in many rules) until you have cleared turnouts, crossovers, and power-operated switches, at which point you may proceed at a higher, permitted speed. This concept ensures you can stop in time for anything you might encounter on the track.
