It's hard to believe that summer is almost over. We all know what that means -- it's back-to-school time. Now's the time to make a concerted effort to stay alert and be smarter behind the wheel. Build in some extra time for your commute…always look twice…stop at all crosswalks…and obey school zone speed limits. And remember that kids, whether they're walking, driving, or riding bicycles, can be very unpredictable. Expect the unexpected.
