A garbage truck is a truck that picks up trash cans and dumps the trash into the truck and transports the trash to landfills. The 1920s saw the first open-topped trucks being used, but due to foul odors and waste falling from the back, covered vehicles soon became more common. These covered trucks were first introduced in more densely populated Europe and then in North America, but were soon used worldwide. In 1937, George Dempster invented the Dempster-Dumpster system in which wheeled waste containers were mechanically tipped into the truck.George Dempster invented the garbage truck and how. The trucks got larger and faster engines to transport trash efficiently and faster. I would improve the garbage truck by making the truck go faster to the trash cans so It will go quicker to the trash cans and the landfills so the trashman’s job goes faster.
