IOWA CITY—Is it time to tune up your driving skills? Attend the AARP Driver Safety Program on Wednesday, Aug. 5 sponsored by the Hills Bank Friends Club. This classroom refresher course, which is open to everyone, will teach defensive driving techniques, new traffic laws, and rules of the road. Especially designed for drivers age 50 and over, you’ll find out how to adjust your driving to normal, age-related changes in vision, hearing, and reaction time. There are no tests, and course completion may even entitle you to an insurance discount.
