What is the maximum speed for Slow Speed signals?

Answer: B — Not exceeding 15 MPH

The maximum speed for Slow Speed signals is established to ensure safety in areas where operational conditions may require more caution, such as in proximity to stations, track work, or areas with limited visibility. Slow Speed signals generally mandate a maximum travel speed of not exceeding 15 MPH. This speed limit is designed to allow conductors and operators adequate time to respond to any unforeseen circumstances that may arise while navigating through these sensitive areas. Understanding the implications of this speed limit is crucial for maintaining safety standards and preventing accidents. Higher speeds could compromise safety, particularly where track conditions, passenger movement, or infrastructure might present hazards. Therefore, adhering to the 15 MPH limit under Slow Speed conditions is essential for operational safety and regulatory compliance.
