What is the speed limit when approaching a railroad crossing with limited visibility?

When approaching a railroad crossing with limited visibility, the speed limit is set at 15 mph. This lower speed limit is specifically designed to allow drivers adequate time to scan for any signs of an approaching train, ensuring they can stop safely if necessary. Reduced visibility conditions, such as those caused by vegetation, buildings, or the curvature of the track, heighten the risk of a collision. Therefore, driving at a slower speed provides drivers with the reaction time needed to respond appropriately to any potential hazards. This safety measure is crucial for minimizing accidents at railroad crossings, where trains can approach quietly and quickly.
