The maneuver where a monster truck spins in tight continuous circles is called donuts.
A donut is a sustained power-slide in which the truck rotates around a tight center while its tires trace a circular path. Throttle, steering angle, tire grip, and weight transfer all help keep the vehicle rotating rather than traveling forward. The maneuver often produces tire smoke, dirt spray, or a visible ring of rubber.
Monster-truck shows commonly feature donuts during freestyle performances, where drivers are judged on control, excitement, and the ability to keep the truck moving. Modern Monster Jam competitions have even included dedicated donut contests.
“Donuts” and “doughnuts” are both accepted spellings in general driving terminology. Some monster-truck communities distinguish a donut from a faster “cyclone,” but those labels are not used consistently across every show or source. The listed answer is therefore the standard, fair quiz answer.
