For those with limited or no mobility of the right foot or leg, the Portable Left-Foot Accelerated Pedal is designed to act and feel like an existing factory pedal. With the PLFA model, the one-piece pedal-actuator arm unit is already affixed to the flexible, non-slip bottom plate, which one simply lays on the floor and aligns (i.e., right pedal in front of the vehicle's accelerator, left pedal to the left of the vehicle's brake). With the AMM model, the rigid bottom plate is first fastened to the floor then the pedals-actuator arm unit thumb-screwed into the plate.
