Steering wheel mounted controls

  • are electronic control rings mounted over or under the steering wheel
  • you squeeze the ring to accelerate - either pushing it or pulling it towards the steering wheel
  • are usually used with a steering column mounted brake
  • as they're electronic, don't need mechanical linkages giving you smoother control
  • are good for people who need the stability of keeping both hands on the steering wheel at all times
  • tend not to interfere with the other controls
  • 'are less obvious and take some of the stigma attached to driving with hand controls'
In January 2017, we held two workshops with new users of driving controls at QEF Mobility Services, Carshalton, Surrey. The research report which is intended for professionals advising disabled people, has useful comments and advice from disabled drivers: Go to Primary driving controls research report here.
