A portable step for supporting a person while working in the engine compartment of a vehicle, such as a truck. The portable step comprises a generally planar member and two legs on the generally planar member having a wheel attachment assembly at their upper ends for hooking onto either the front wheel or rear wheel of the vehicle thereby to suspend the planar member in a position wherein it is generally horizontal and at an elevation above the ground where a person standing on the planar member has convenient access to the engine compartment of the vehicle. Also disclosed is such a portable step wherein the wheel attachment assembly and the planar member are collapsible to minimize the size of the portable step for storage.
