The result of inertia due to failure to wear a seatbelt will result in the passenger becoming a projectile. The weight of the passenger and the speed of travel prior to the collision will be multiplied together to equal the force their body will endure. For example, the force a person will be subjected to for a passenger weighing 100 pounds, in a vehicle traveling at 60 mph, will be the equivalent of 6000 pounds (3 tons) hitting a brick wall.
