A hand control throttle system includes an actuating mechanism and a sensor. The system is mounted to a standard steering wheel for a vehicle, so that a disabled driver can operate the throttle using a single hand (either right or left) while the hand is also holding the steering wheel.

A cruise control for a vehicle having a mounted rotatable accelerator sleeve and throttle housing which is mounted to a handlebar. The cruise control mounts entirely to the accelerator sleeve and rotates in perfect unity with the throttle when it is rotated. The cruise control is mounted between the throttle housing and the rubber/plastic grip's inner end, directly onto the accelerator sleeve. When the single button of the cruise control is pressed, the cruise control engages and uses friction against the surface of the throttle housing to hold the throttle in place. The operator can force the throttle to rotate by overpowering the friction caused by the cruise control, or preferably, they can disengage the cruise control by pressing the single button again, resetting the cruise control to be engaged again by pressing the single button.
