A portable hand control system for operating an accelerator and brake pedal of a vehicle by hand. The portable hand control system includes an accelerator control rod releaseably couplable to the accelerator pedal of the vehicle and a brake control rod releaseably couplable to the brake pedal of the vehicle. A thumb control is mounted on the accelerator control rod for selectively receiving a thumb of a user controlling the accelerator control rod. A handle is mounted the brake control rod selectively receiving a hand of a user controlling the brake control rod. A coupling member is mounted on the brake control rod for operationally coupling the accelerator control rod to the brake control rod. A quick release coupling system is provided for coupling the accelerator control rod to the accelerator pedal of the vehicle and for coupling the brake control rod to the brake pedal of the vehicle.
