A toy vehicle play set may include a toy vehicle and a track assembly including a track along which the vehicle may travel. In some examples the vehicle may include a drive mechanism that is adjustable for changing the speed of the vehicle, and a play set may include a speed changer for selectively changing the vehicle speed. In some examples, the track assembly may include a selectively actuated trapdoor in the track. In some examples, the play set may include a vehicle trap assembly having a cover defining a chamber for receiving, for example, a vehicle passing through the trapdoor opening. In some examples, the vehicle trap may include an assembly, such as the vehicle trap that falls apart when contacted by a vehicle traveling along the track.
