People who wear their shoulder belt under their arm will not be protected in cases of accidents. Their chest can go forward and hit the steering wheel or the windshield.

NO..
Yes you do. Seat belt keeps you from sliding under the shoulder belt. Shoulder belt keeps your body (and head) from slamming forward into things like the dashboard. Put them both on. If it bothers you, pretend you are flying a jet fighter. Pilots wear them too.
This can vary depending on if seat belt use is required by law but rule of thumb is: If the car came equipped with the shoulder belt it must be used.
You undo the belt strap at the bottom, the shoulder strap (on the same side). Slip into it, then redo-up the belt and shoulder.
The proper way to wear a seatbelt is to wear it snugly against the body. With a should belt, it should be over your shoulder, not under. When wearing a lap belt, it should not go across the stomach, but lowered near the pelvic bone.
If the car is equipped with shoulder belts you are required to wear them.
Be sure to wear your seat belt and shoulder belt in a vehicle with air bags.
if you are on the right hand side of the car you put the seatbelt on your right shoulder and if you are on the left put the seatbelt on your left shoulder
if there are cracks on under side, wear of belt,,grooves missing on belt, just normal wear and tear!!
Short answer is Yes. As far as I know, most cars have the 3 point seat belt.
