Play systems of the present disclosure comprise a children's ride-on vehicle and a companion track. The companion vehicle and track each include a guide surface that is complementary to the companion apparatus and configured to guide the vehicle along a path of travel defined by the track. The children's ride-on vehicle may be powered, steerable, and configured to operate on and off the track. When the children's ride-on vehicle is guided and/or steered along the path of travel, the complementary guide surfaces do not substantially impede progress of the vehicle. When the children's ride-on vehicle is guided and/or steered away from the path of travel, the complementary guide surfaces contact and/or frictionally engage to direct the vehicle along the path of travel and/or to slow progress of the vehicle.
