It may be hard, but the best place to start is having an honest conversation with yourself. How have your physical abilities changed? What about your thinking skills? This exercise is about recognizing areas where you might need extra help or training.
Talk to your health care team about wanting to drive again. Sometimes stroke survivors are unaware of the effects the stroke has on driving skills. You may feel it's safe to drive when it isn't. Your team can evaluate problem-solving abilities, reflexes, vision, memory, and visual-spatial skills. Each of these areas is critical to safe driving. Certain post-stroke medicines, such as those for pain or seizures, can also make driving unsafe.
In some places, doctors are required to tell local driving authorities about strokes and provide written documentation that you are safe to drive. Ask your doctor what the rules are where you live or contact your state DMV and ask for the office of driver safety.
