What term describes being able to stop within half the range of vision and to stop for obstructions?

• A. Restricted Speed
• B. Caution Speed
• C. Maximum Authorized Speed
• D. Restricted Proceed

Answer: (A)

Restricted speed is the pace at which a train must operate when conditions don’t allow you to see far enough ahead to stop safely at normal speeds. The rule is that you must be able to stop within the range of vision you have and be prepared to stop for any obstruction or signal you might encounter. Saying you can stop within half the range of vision emphasizes that when visibility is limited or the track environment is risky (yard limits, curves, single-track sections, or areas with obstructions), you must be able to bring the train to a stop quickly and safely. This makes it the best fit for the description. Caution speed describes a general slowdown for safety but doesn’t specify the requirement to stop within a limited distance. Maximum Authorized Speed is simply the highest permitted speed on a track, not about stopping capability. Restricted Proceed refers to moving with certain restrictions, not specifically the stopping-distance requirement of restricted speed.
