It's time for the hardworking trucks at the construction site to get cleaned up! But when the narrator tries to round up the muddy machines, they dig in their wheels and refuse to be led away. They don't want to waste time being soaked and lathered, scrubbed high and low--they want to flatten soil, haul dirt, carry bricks, and lift beams. They want to WORK!

When the trucks discover that washing away the grime means they get to keep loading and lifting, they snap into action. It turns out that getting clean actually is work! Together, the trucks sponge and scrub until they sparkle. As they revel in their newfound gleam, the narrator reveals they're cleaning up for an extra special purpose--a truck parade! The shiny machines roll down the street to the cheers of a diverse group of truck fans.

With charming, expressive illustrations and playful rhyming text, this book brings the construction site to life in an energetic tale that will have readers shouting, "Hooray for trucks!"
