At uncontrolled railroad crossings, the speed limit is:

• A. 25 mph
• B. 20 mph
• C. 15 mph
• D. 30 mph

Answer: (C)

Approaching a railroad crossing without warning devices, you slow down to 15 mph. This lowered speed gives you enough time to look and listen for approaching trains and to stop safely if one is coming. Trains can be long and close quickly, and there are no gates or lights to tell you when to go, so moving at a light, cautious pace helps prevent getting into a position where you can’t stop before the tracks. Higher speeds would reduce your reaction and stopping distance, increasing the risk of a collision. If warning devices are present, you must follow them, but the question focuses on uncontrolled crossings, where 15 mph is the standard.
