A 62 year-old male was about to be discharged from the hospital. He was diagnosed with a stroke and was started on medications. He regained some of his strength in both upper and lower extremities but still has a visual field defect with loss of vision on the same side of both eyes. He has an outpatient appointment with a neurologist in two weeks. He is a commercial truck driver and the primary breadwinner for his family. You advised him not to drive until he regains full strength and complete vision. However, the patient reports that he cannot afford not to work and expresses strong desire to drive from tomorrow. What is the most appropriate step in the management of this patient regarding his driving?
