Patricia H., I did check with my auto insurance agent about driving with PD and he advised that is was not illegal nor dangerous unless I felt I was unable to safely control the vehicle. Some time ago I read that some eastern U.S. states gave regular driving tests to qualify PWP for continued driving. Texas so far does not have such a program. As long as we PWP continually evaluate our own driving skills honestly and stop driving before we become a hazard on the highway, we should be okay. It will be a hard decision for me to stop driving, but I know it is coming someday. Best regards and good luck, Bob Baker
