Working Car Vroom

This is an app where you can watch and play with the unique movements of various working vehicles. It features simple tap operations with various interactive elements.

The app includes construction site vehicles such as power shovels, dump trucks, mixer trucks, bulldozers, power loaders, aerial work platforms, pump trucks, garbage trucks, trucks, container trucks, motor graders, vacuum trucks, postal delivery vehicles, courier trucks, camping cars, lumber trucks, car carriers, road rollers, tankers, convoy trailers, F1 cars, and giant heavy machinery like big dump trucks. Emergency vehicles such as police cars, ambulances, fire trucks, ladder trucks, and highway patrol cars also appear, along with public transportation vehicles like buses, taxis, and school buses.

Tapping an icon changes the type of vehicle running in the center of the screen. Tapping a vehicle lets you see its unique movements. Other passing vehicles can also be tapped to trigger different actions. Sometimes, dinosaurs or UFOs may appear—try tapping them to see what happens. Trains, including bullet trains, also appear in the background.

Pressing the **Special Item Button** (available in the unlimited version) consumes **5 hearts** and allows unlimited use of special items for **60 seconds**. There are four types of special items, and activating one enables unlimited use of that button for a certain period:

1. **Convoy Trailer Button** – Large vehicles such as convoy trailers, tankers, and car carriers appear.

2. **F1 Machine Button** – Many F1 cars appear.

3. **Big Button** – Working vehicles grow larger in two stages.

4. **Big Dump Button** – Four types of large heavy machinery, including big dump trucks, appear. Tapping them activates their unique movements.
