Is there anyone left who still disputes the importance of wearing a seatbelt every single time you get in the vehicle, no matter how short the distance? We hope not. Buckle up every time you get behind the wheel. If you want to know just how important it is, ask your local EMT to show you a "star" on a windshield. Then ask how it got there. Then think about what kind of headache that would cause.
Here, too, we'd consider information from any quarter, including family, friends and neighbors to be admissible evidence.
