A modular pedal assembly for use with a vehicle that includes a prime mover, a control circuit, and a brake assembly. The modular pedal assembly including a base that is removably connectable with the vehicle, a brake pedal, an accelerator pedal that is displaceable between a first position and a second position, and a control output regulator that includes a first sensor and a second sensor. In a vehicle having an electric motor prime mover, the first sensor is a limit switch electrically connected to the control circuit, and the second sensor is a variable resistor. In a vehicle having an internal combustion engine prime mover, the first sensor is a limit switch operable to control a starter motor, and the second sensor is a limit switch operable to control a spark plug ignition.
