Hand controls are devices installed in vehicles that allow those who are not able to use the gas and brake pedals the ability to drive. There are a variety of designs and styles that offer some variations in function to meet the needs of the individual user.
They can be set up for right-handed or left-handed use but must only be installed in vehicles with automatic transmissions and power steering.
I have just finished posting an article in the vehicle equipment section of Mobility Basics on hand controls. For more information please visit http://mobilitybasics.ca/vehicle-equipment/vehicle-hand-controls
