In order to use the B.D.F. Hand Control, a vehicle with automatic transmission is required, which is the only requirement for the installation. No other modification of a vehicle is necessary. The installation does not change the operation of a vehicle since accelerator and brake pedals remain unobscured, thus allowing normal operation for people without limited movement of legs. The main bracket of the B.D.F. Hand Control flange is screwed under the seat slider bracket (the existing screws of the bracket are used). The uniquely designed longitudinal bracket allows adjustments to various types of vehicles, therefore subsequent readjusting is possible. There are also no traces of usage in the car interior even after a potential removal, without any damage on liners or other parts of the vehicle.
With the help of the B.D.F. Hand Control, a disabled person-driver can operate a vehicle manually - using the lever to accelerate (by moving it backward) and to brake (by moving it forward). In terms of safety, it is particularly important that both of these functions can't be performed simultaneously.
