An electric slot car racing track includes a "spin out track" for providing an intermittent and temporary obstruction to one or more of the slot car racing lanes. The obstruction is provided in the form of a simulated vehicle which temporarily blocks the path of one or more of the racing lanes to test the skills of the participating drivers in avoiding the obstruction. The "spin out track" provides an added degree of unpredictability or chance to the ultimate outcome of the race, therefore making the toy racing set the more attractive to younger or less skilled children. The frequency and duration of the intermittent obstruction is regulated by electrical controls which are actuated by movement of the racing vehicles over a sensing element. The electrical control is provided as a unit integrated into the spin out track section such that this track section may be installed and employed in conventional slot racing sets.
