class A
No- NOT wearing a seatbelt is NOT safe. Wearing a seatbelt IS safe. It prevents you from being slammed against the intterior of the car, or being thrown out where you will be crushed by the car. You are NOT strong enough to brace yourself against the impact.
You are not more likely to survive a collision if you are thrown from the vehicle. You need to wear a seat belt.
...body from being flung into the steering wheel/wind shield or thrown out of the car in case of an accident.
No.
Under United States Army regulations, any accident that results in a fatal injury to any personnel is classified as Accident Class A.
Prevents your head from going thru the windshield (ouch). Also prevents you from being thrown out of the car during an accident.
In a 15 mph crash without a seatbelt, the crash test dummy would experience the full force of the impact which could result in injuries such as head trauma, whiplash, or broken bones. Without the seatbelt to restrain the dummy's movement, it may also be thrown forward or out of the vehicle, increasing the risk of serious harm or death.
The seat belt is meant to keep you in place during impact. If you are not wearing one and the impact is strong enough, you could be thrown through the windshield or around inside the vehicle. It is meant for protection to minimize injury.
Wearing a seatbelt significantly reduces the risk of serious injury or death in a car accident by preventing you from being thrown from the vehicle or hitting the windshield. Seatbelts also help to distribute the force of a collision across the strongest parts of your body, such as the chest and pelvis, minimizing the impact on vulnerable areas. It is a simple and effective way to protect yourself and others in the car.
Nothing compared to the risk of not wearing one. (In theory, you may be trapped in the car. However, all research shows that this is negligble a danger compared with being thrown through the windshield at 30 miles per hour.)
If you're in the rear seat and the car has a head-on collision you will be thrown into the people in the front seats with an amazing force. You might injure them directly, or cause their belts to snap, leaving them free to get thrown into the windshield or be ejected out of the car.
