One Mom's tragedy made us stop and take action.

The tragedy: Georgia State Patrol has confirmed that Mom Sheila Vines, her husband, and their 13-year-old son were killed Wednesday night when their car crashed into a lake during wintry weather conditions, reports WSBTV.

Take action: In an accident like this one, the car's electrical system often short-circuits before the car fills with water. That means the windows won't roll down and the seatbelts won't come off. But a car hammer can cut seatbelts and break auto glass—and possibly save your life. And it can help in any emergency situation where you or someone else in your family is trapped in a car.  Buy a car hammer for every vehicle you own.
