“Click!” That’s the sound of safety. That’s the sound of survival. That’s the sound of a seat belt locking in place. Seat belts save lives and that’s a fact. That’s why I don’t drive anywhere until mine is on tight. Choosing to wear your seat belt is as simple as choosing between life and death. Which one do you choose? Think about it. When you’re driving in a car, you may be going 100 km/h or faster. That car is zipping down the road. Then somebody ahead of you locks up his or her brakes. You don’t have time to stop. The car that you are in crashes.

Some people think that seat belts are uncool. They think that seat belts cramp their style, or that seat belts are uncomfortable. To them, I say, what’s more uncomfortable? Wearing a seat belt or flying through a car windshield? What’s more uncool? Being safely anchored to a car, or skidding across the road in your jean shorts? Wearing a seat belt is both cooler and more comfortable than the alternatives. Let’s just take a closer look at your choices. If you are not wearing your seat belt, you can hop around the car and slide in and out of your seat easily. That sounds like a lot of fun. But, you are also more likely to die or suffer serious injuries. If you are wearing a seat belt, you have to stay in your seat. That’s no fun. But, you are much more likely to walk away unharmed from a car accident. Hmmm... A small pleasure for a serious pain. That’s a tough choice. I think that I’ll avoid the serious pain.
