The invention relates to a variable speed limiting device suitable for an expressway section prone to water accumulation. The variable speed limiting device comprises a water accumulation monitoring frame and a speed limiting display frame. A water accumulation monitoring unit, a first power supply unit and an equipment box are arranged on the water accumulation monitoring frame; a display unit and a second power supply unit are arranged on the speed limiting display frame; the first power supply unit supplies power to the water accumulation monitoring unit and the equipment box; and the equipment box controls work of the water accumulation monitoring unit and sends a display instruction to the display unit. The second power supply unit supplies power to the display unit, and the display unit receives the display instruction sent by the equipment box and executes display. The water accumulation monitoring unit comprises a plurality of accumulated water sensors, wherein one accumulated water sensor is correspondingly arranged above each lane; and the display unit comprises a plurality of speed limiting display panels, wherein one speed limiting display panel is correspondingly arranged above each lane. The road speed limit information can be adjusted in real time according to the real-time accumulated water depth of the road and different accumulated water depths on different lanes of the same road.
