Some of the world's best monster truck drivers were in Singapore to show off their skills at the one-night-only Monster Jam, held yesterday at the National Stadium.
These drivers can steer the huge trucks into doing gravity-defying backflips and vertical two-wheel tricks.
The event also involved high-speed racing of up to 120kmh and a freestyle competition.
A typical monster truck weighs 5,400kg, and is 3.8m high and 3.2m wide. A single tyre weighs almost 300kg and is 1.67m high.
