If approaching the limits of a planned work location and the Employee in Charge grants permission to pass through the limits without stopping at the red board, what speed must you maintain through the limits unless otherwise specified?

• A. Authorized Speed
• B. Restricted Speed
• C. Maximum Speed
• D. Slow Speed

Answer: (B)

Restricted speed is the standard speed to maintain when passing through planned work limits without stopping at the red board. This speed is defined as the rate at which you can stop within the range of vision and be prepared to stop before any obstruction or signal. In a work zone, conditions can change quickly: workers, equipment, and temporary signals may not be visible far ahead, so maintaining restricted speed provides a safety margin. The instruction “unless otherwise specified” means you only go faster if the Employee in Charge explicitly tells you to; otherwise, you stay at restricted speed to protect everyone in the area. Higher speeds like Authorized Speed would require explicit authorization, while Maximum Speed is the normal line speed—not the default in a work-limits context, and Slow Speed isn’t a formal term used for this rule.
