n the event of a car crash, seat belts reduce your risk of suffering an injury and even death. If you are in a car accident, wearing a seat belt will lessen the severity of your injuries. Here’s what the statistics say regarding the risk of not wearing a seat belt:
If you’re sitting in one of the front seats of a passenger car that gets in an accident, wearing your seat belt decreases your risk of suffering a fatal injury by 45 percent, and decreases your risk of suffering a moderate to critical injury by 50 percent.If you’re sitting in a light truck that gets in an accident, wearing your seat belt decreases your risk of suffering a fatal injury by 60 percent, and decreases your risk of suffering a moderate to critical injury by 65 percent.
Here are a few crash statistics from 2015 that explain how important it is to buckle up and why doing so can save your life:
In 2015, there were 35,092 accident-related deaths48 percent of those 35,092 weren’t wearing their seat belts when they got into those car accidents.Seat belt use saved the lives of an estimated 13,941 people in 2015.
Now, keep in mind that, among people in the United States, the seat belt usage rate is 90.1 percent. Despite the fact that only 9.9 percent of Americans neglect to use their seat belts, those non-users make up 48 percent of the casualties in car accidents.
You can likely attribute some of this to riskier driving behaviors. After all, if a driver takes the risk of driving without a seat belt, it stands to reason that they may commit other riskier driving behaviors, such as speeding. But the more significant factor in preventing higher death and injury rates is simply to just wear your seat belt at all times. Let’s take a look at how.
HOW A SEAT BELT WORKS
Before we go over the seat belt, it’s important to understand what happens to your body in a car accident. When you’re in a car, your body is moving at the same speed as the car. If you’re driving on the freeway going 70 miles per hour, then your body is also traveling at 70 miles per hour.
A car accident may stop your car, but it doesn’t stop your body, which still has that forward momentum. Without anything to hold you in place, your body would go flying forward while your car stopped. This could send you flying out of the car or cause you to collide with part of the car.
A seat belt holds your body in place during a car accident. The modern version of the seat belt is the three-point seat belt, which has the shape of the letter “y.” When you get into a car accident while you’re wearing a three-point seat belt, the seat belt disperses your body’s momentum into your chest, your shoulders and your pelvis. Depending on the speed you were going and the suddenness of the impact, this could still leave you sore and bruised, but it will keep you in your seat.
The three-point seat belt is a combination of two earlier versions of the seat belt – the lap belt and the sash belt.
The lap belt is still the seat belt of choice in airplanes, and it used to be common in cars. Many cars would have three-point belts in the front seats and lap belts in the back seats. The problem with the lap belt is that it only disperses your body’s momentum in that one area. All that force near your waist can cause spinal damage and even paralysis.
The sash belt has typically been used with lap belts in cars, but originally, it was a completely separate component. This meant that the occupant could use only the lap belt or only the sash belt. Just like the lap belt, the sash belt alone has a dangerous issue. If you get in a car accident while wearing only the sash belt, you could slide forward underneath the sash belt, which means it doesn’t provide sufficient protection.
Auto manufacturers began combining the lap belt and sash belt into one component, thus creating the modern three-point seat belt found in almost every vehicle. This has all the benefits of the previous two types of seat belts without their weaknesses.
