That’s an achievement Chicago should strive to match and exceed. Ordinary people can help with adopting safe practices. Such as: Don’t talk or text on your smartphone when you’re driving — or when you’re walking across a street. Drive within the speed limit and don’t blow through red lights. In short, keep the safety of yourself and everyone else foremost in your mind, whether you’re behind the wheel or on foot. That is the surest way to prevent accidents.
