splashboard

noun

1. A guard towards the front of a horse-drawn vehicle, to prevent splashing by mud or water from the road.

   “The old driver was hanging over the splash-board like some grotesque scarecrow, his arms dangling absurdly in front of him.”

   “Reluctantly Cora handed up the basket and was hauled up over the splash-board herself, and bumped down on the chaffbags as Ted Farrell clicked up the horse again.”
