Do you need a doctor to tell you that your belly is touching the wheel? Most car seats and steering wheels can adjust these days.
I know my steering wheel and chair are adjustable however it was said to ME that for insurance purposes I wouldnt be covered in an accident.

and BTW - I am quite capable of determining whether or not I can drive. I was simply asking a question as to whether there was a law or if anyone else had needed a medical certificate to be approved to drive as *I* was told.
