Which statement best describes the maximum speed under DROP PANTOGRAPH INSTRUCTION FORM D unless otherwise stated?

Explanation:
When a Drop Pantograph Instruction Form D is in effect, the default operating speed is 30 mph unless the instruction specifically states a different limit. This provides a safe, conservative speed for operation with the pantograph down, reducing the risk of damage to the overhead system or equipment and ensuring predictable performance. The phrase “unless otherwise stated” means you only use a higher or lower speed if the Form D explicitly lists it for a given section. So the best choice is the one that says not exceeding 30 mph unless otherwise stated.
